Future Vertical Lift

After a decade of combat from Operation Iraqi Freedom and Operation Enduring Freedom, the U.S. Department of Defense found that the U.S. Army's rotorcraft fleet was wearing out. Combat operations made the helicopters fly five times more often than in peacetime. Manufacturers have been remanufacturing and upgrading existing families of aircraft without creating original platforms. The Future Vertical Lift (FVL) concept is to create a new rotorcraft that uses new technology, materials, and designs that are quicker, have longer range and higher payload capacity, are more reliable, easier to maintain and operate, have lower operating costs, and can reduce logistical footprints. FVL is to create a family of systems to replace most Army helicopters. The Joint Multi-Role (JMR) phases will provide technology demonstrations. JMR-TD will develop the aerial platform; JMR Phase I will develop the air vehicle; JMR Phase II will develop mission systems. The Army plans to acquire as many as 4,000 aircraft from the FVL program.{{Citation |url= http://www.aviationtoday.com/rw/military/dod/Future-Vertical-Lift&thinspAn-Overview_79167.html |title= Future Vertical Lift: An Overview |newspaper= Aviation today |date= 1 May 2013 |access-date= 17 September 2021 |archive-date= 13 September 2016 |archive-url= https://web.archive.org/web/20160913225533/http://www.aviationtoday.com/rw/military/dod/Future-Vertical-Lift%26thinspAn-Overview_79167.html |url-status= live}}.

In October 2011, the Deputy Secretary of Defense issued the FVL Strategic Plan to outline a joint approach for the next generation vertical lift aircraft for all military services. The Strategic Plan provided a foundation for replacing the current fleet with advanced capability by shaping the development of vertical lift aircraft for the next 25 to 40 years. It indicates 80 percent of decision points for the DoD vertical lift fleet to either extend the life, retire, or replace with a new solution occurring in the next eight to ten years. Implementation of the FVL Strategic Plan will impact vertical lift aviation operations for the next 50+ years.{{Citation |url= http://www.defensemedianetwork.com/stories/joint-multi-role-jmr-the-technology-demonstrator-phase-contenders/ |title= Joint Multi-Role (JMR): The Technology Demonstrator Phase Contenders |newspaper= Defense media network |date= 8 October 2013 |access-date= 13 October 2013 |archive-date= 12 October 2013 |archive-url= https://web.archive.org/web/20131012232604/http://www.defensemedianetwork.com/stories/joint-multi-role-jmr-the-technology-demonstrator-phase-contenders/ |url-status= live}}.

In March 2013, the Army asked the industry to submit proposals for an effort called the Alternative Engine Conceptual Design and Analysis. Although formal requirements for the FVL family of systems had not yet been set, they will need to have hover, speed, range, payload, and fuel efficiency characteristics "beyond any current rotorcraft". This may require an aircraft that can hover at {{convert|10000|ft|||}} and cruise at {{convert|30000|ft|||}}. Capabilities include good hover maneuverability at high altitude.{{Cite web |url=https://www.fbo.gov/utils/view?id=a5565b60f76fb235432f6779d0a9c97d |title=Archived copy |access-date=6 March 2016 |archive-date=17 February 2017 |archive-url=https://web.archive.org/web/20170217134842/https://www.fbo.gov/utils/view?id=a5565b60f76fb235432f6779d0a9c97d |url-status=live}}{{Cite web |url=https://www.fbo.gov/utils/view?id=30d9477b774fd2e196779f3a65fb934b |title=Archived copy |access-date=6 March 2016 |archive-date=17 February 2017 |archive-url=https://web.archive.org/web/20170217134755/https://www.fbo.gov/utils/view?id=30d9477b774fd2e196779f3a65fb934b |url-status=live}}

The engine will require alternative, advanced engine/power system configurations that enable enhanced mission capability, such as improved time on station, increased mission radius, and quieter operation.

AVX has teamed with Rockwell Collins, General Electric, and BAE Systems. It features entry doors on both sides of the fuselage with a large rear ramp for easy cargo handling. Both versions have retractable landing gear, and the attack variant carries all armaments stored inside until needed to provide a clean aerodynamic design.

The company refers to the unnamed concept as an "innovative compound coaxial helicopter" capable of achieving 80 percent of the speed of the V-22 Osprey at half the cost.

AVX considers its position as a smaller company (with 25 employees, some of which worked on the V-22) to its advantage without a legacy or burden of overhead attributes like larger defense corporations; if selected to supply an aircraft, AVX will likely have a teaming arrangement with another company that can handle assembly, integration, and production support.[https://www.flightglobal.com/news/articles/avx-expects-work-to-continue-on-its-future-vertical-lift-398898/ AVX expects work to continue on its future vertical lift design] {{Webarchive|url=https://web.archive.org/web/20140506203132/http://www.flightglobal.com/news/articles/avx-expects-work-to-continue-on-its-future-vertical-lift-398898/ |date=6 May 2014}} – Flightglobal.com, 6 May 2014 Like Sikorsky, AVX considers coaxials as unsuitable for heavy-lift, and suggests their tiltrotor instead for Capability Set 4 (Chinook replacement).{{cite web|url=https://www.flightglobal.com/news/articles/avx-would-replace-heavy-lift-chinook-with-tiltrotor-424834/ |title=AVX would replace heavy-lift Chinook with tiltrotor|work=Flightglobal|access-date=1 May 2016|archive-date=1 May 2016|archive-url=https://web.archive.org/web/20160501095832/https://www.flightglobal.com/news/articles/avx-would-replace-heavy-lift-chinook-with-tiltrotor-424834/|url-status=live}}

Karem Aircraft proposed to design an optimum-speed tiltrotor (OSTR), designated the TR36TD demonstrator. It would have had twin {{convert|36|ft|m|adj=mid|-diameter}} variable-speed rotors powered by existing turboshaft engines. The production version of the TR36D would have had a level flight speed of {{convert|360|knot|mph km/h|abbr=on}}. Karem says its variable-speed OSTR configuration offers advantages in weight, drive train, and aerodynamic and propulsive efficiency. It has high speed, "robust" hover performance at altitude, higher climb rate and sustained maneuverability, and longer range than other vertical-takeoff-and-landing configurations. They also say it offers reduced complexity, inherent safety advantages, simplified maintenance, and low total ownership cost.[http://www.aviationweek.com/Article.aspx?id=/article-xml/awx_10_02_2013_p0-623233.xml&p=1 Karem Unveils Variable-Speed Tiltrotor For U.S. Army JMR Demo] {{Webarchive|url=https://web.archive.org/web/20131005015215/http://www.aviationweek.com/Article.aspx?id=%2Farticle-xml%2Fawx_10_02_2013_p0-623233.xml&p=1 |date=5 October 2013}} – Aviationweek.com, 2 October 2013 {{asof|2016}}, Karem continues to work on versions of the TR36, intending to start testing rotors around 2018.{{cite web|url=https://www.flightglobal.com/news/articles/karem-readies-optimum-speed-tiltrotor-for-fvl-424842/ |title=Karem readies optimum-speed tiltrotor for FVL|work=Flightglobal|access-date=1 May 2016|archive-date=2 May 2016|archive-url=https://web.archive.org/web/20160502114445/https://www.flightglobal.com/news/articles/karem-readies-optimum-speed-tiltrotor-for-fvl-424842/|url-status=live}}

Piasecki Aircraft was bidding its PA61-4 Advanced Winged Compound (AWC). The full-compound version was planned to fly at {{convert|233|knot|mph km/h|abbr=on}} and used their vectored-thrust ducted propeller (VTDP), flown previously on the Piasecki X-49. It propelled the aircraft and had a long-span wing for lift and anti-torque. The wing pivoted in pitch for addition flight control and to reduce rotor download in the hover. Removing the wing but retaining the VTDP produced the {{convert|180|knot|mph km/h|abbr=on}} thrust compound version, which could be used for shipboard operations. Replacing the VTDP with a conventional tail rotor produced the {{convert|160|knot|mph km/h|abbr=on}} version, which was slower but was lighter, cheaper, and could better handle external-lift or vertical-replenishment missions.

On 5 June 2013, Bell announced that its V-280 Valor design had been selected by the Army for the Joint Multi-Role (JMR) Technology Demonstrator (TD) phase. The Army classified the offering as a Category I proposal, meaning it is a well-conceived, scientifically or technically sound proposal pertinent to program goals and objectives with applicability to Army mission needs, offered by a responsible contractor with the competent scientific and technical staff supporting resources required to achieve results.[http://www.bellhelicopter.com/en_US/News/PressReleases/NewsRelease/NewsRelease.html?ReleaseID=1827292 Bell V-280 Valor Selected for Army’s JMR-TD Program] {{Webarchive |url=https://web.archive.org/web/20130718135146/http://bellhelicopter.com/en_US/News/PressReleases/NewsRelease/NewsRelease.html?ReleaseID=1827292 |date=18 July 2013}} – Bell press release, 5 June 2013.[http://www.flightglobal.com/news/articles/us-army-selects-bell-sikorskyboeing-team-for-jmr-demonstration-386742/ US Army selects Bell, Sikorsky/Boeing team for JMR demonstration] {{Webarchive|url=https://web.archive.org/web/20130614082442/http://www.flightglobal.com/news/articles/us-army-selects-bell-sikorskyboeing-team-for-jmr-demonstration-386742/ |date=14 June 2013}} – Flightglobal.com, 5 June 2013.

The Boeing-Sikorsky team, pitching the high-speed compound helicopter design based on the X2 prototype, also reported they were invited to negotiate a technology investment agreement for the JMR-TD Phase I program.

EADS withdrew from the program before designs had been selected, and Piasecki Aircraft was not chosen to continue in the effort.

On 31 July 2013, Boeing and Sikorsky pledged they will invest more than double the amount money the government is spending on JMR if the team is chosen to build and demonstrate a rotorcraft for the program.[http://www.janes.com/article/25358/boeing-sikorsky-pledge-to-more-than-double-us-army-s-initial-jmr-investment Boeing-Sikorsky pledge to more than double US Army's initial JMR investment] {{Webarchive|url=https://web.archive.org/web/20130805101303/http://www.janes.com/article/25358/boeing-sikorsky-pledge-to-more-than-double-us-army-s-initial-jmr-investment |date=5 August 2013}} – Janes.com, 31 July 2013

On 2 October 2013, the U.S. Army awarded technology investment agreements (IIA) to AVX Aircraft, Bell Helicopters, Karem Aircraft and Sikorsky Aircraft under the Joint Multi-Role Technology Demonstrator Phase I program. There are two general types of proposals: tiltrotors with rotors that serve as both rotors and conventional propellers, and compound helicopters that use vertical rotors and separate rear-mounted propellers. AVX and Sikorsky are offering compound designs with two counter-rotating rotors to provide vertical lift. For forward movement, AVX uses two ducted fans and Sikorsky uses a single propeller on the back. Bell is offering the V-280 Valor tiltrotor. Karem Aircraft is offering a tiltrotor with optimum-speed rotors, allowing the aircraft to speed or slow the propellers depending on speed or efficiency demands. Similar technology was used on the A160 Hummingbird. JMR-TD is to develop and demonstrate an operationally representative mix of capabilities, technologies, and interfaces to investigate realistic design trades and enabling technologies.

The TIAs give the four teams nine months to complete preliminary design of their rotorcraft, which the Army will then review and authorize the construction of two competing demonstrators to fly in 2017. While there was a potential for an early downselect, the four teams are focused on the 2017 flight demonstrations. Emerging results from JMR TD Phase 1 will be used to inform the FVL effort regarding vehicle configurations, the maturity of enabling technologies, attainable performance and capabilities, and will highlight affordable technical solutions required to achieve those capabilities.[http://www.flightglobal.com/news/articles/army-selects-four-companies-for-advanced-rotorcraft-concepts-391299/ Army selects four companies for advanced rotorcraft concepts] {{Webarchive|url=https://web.archive.org/web/20131005122857/http://www.flightglobal.com/news/articles/army-selects-four-companies-for-advanced-rotorcraft-concepts-391299/ |date=5 October 2013}} – Flightglobal.com, 3 October 2013{{cite web |url=http://www.defensenews.com/article/20131002/DEFREG02/310020022/Four-Companies-Get-US-Army-s-Nod-Begin-Critical-Helicopter-Designs |archive-url=https://archive.today/20131004180126/http://www.defensenews.com/article/20131002/DEFREG02/310020022/Four-Companies-Get-US-Army-s-Nod-Begin-Critical-Helicopter-Designs |url-status=dead |archive-date=4 October 2013 |title=Four Companies Get US Army's Nod to Begin Critical Helicopter Designs |publisher=DefenseNews |date=2 October 2013 |access-date=4 October 2013 |author=McLeary, Paul}} Each of the four teams received $6.5 million from the Army for this phase of the program.{{usurped|1=[https://web.archive.org/web/20131027030048/http://defensetech.org/2013/10/25/doubts-swirl-around-armys-next-generation-helicopter-fleet/ Doubts Swirl around Army’s Next Generation Helicopter Fleet]}} – Defensetech.org, 25 October 2013 On 21 October 2013, defense executives bidding for the program stated that the Army plans to downselect to two companies in 2014, who will then develop prototypes for flight tests in 2017.

Submissions for JMR evaluations were to be entered by the four competitors by June 2014, with the Army selecting two to build demonstrators to fly between 2017 and 2019, but the Army may choose a non-JMR vehicle for FVL, and may pursue different types for different FVL classes.

After the flight tests and technology development, JMR will end and a Request for Proposals (RFP) will be issued open to all companies to begin the projected $100 billion FVL effort. Demonstrators developed under JMR will be "X-planes" to demonstrate some key technologies, but they won't have production-representative engines or real mission systems architecture; JMR will show off technologies to enable Army rotary-wing aviation to make the next leap in speed, lift, protection, and interoperability under FVL for the 2030s.

The program is intentionally slow-paced partly due to the challenges seen in the Joint Strike Fighter program and failures of past programs like Future Combat Systems, which was cancelled after complex requirements could not be met within established budgets and timelines. A contract for a joint common architecture standard was to be awarded in July 2014 for lab-based testing, and the FVL RFP is to be issued in 2019.[https://archive.today/20140527161024/http://www.defensenews.com/article/20140505/DEFREG02/305050028/Step-by-Step-US-Army-Slowly-Nears-Apache-Black-Hawk-Replacements Step by Step: US Army Slowly Nears Apache, Black Hawk Replacements] – Defensenews.com, 5 May 2014 The Sikorsky-Boeing team submitted the SB-1 Defiant design and risk report to the Army in mid-June for JMR."[http://news.usni.org/2014/06/17/sikorsky-boeing-team-submit-new-army-helicopter-design Sikorsky and Boeing Team Submit New Army Helicopter Design] {{Webarchive|url=https://web.archive.org/web/20140619203258/http://news.usni.org/2014/06/17/sikorsky-boeing-team-submit-new-army-helicopter-design |date=19 June 2014}}" – News.USNI.org, 17 June 2014.

The Army is looking at five criteria to downselect JMR-TD entries: how much the design advances the services' science and technology goals; whether the design meets performance specifications; how well the demonstrator validates specifications; whether the competitor has kept to their schedule; and whether the company has the skills and competency to carry out a flight demonstration. Even with the prospect of sequestration returning in FY 2016, the JMR program will likely be spared from cuts or cancellation due to the Army's support of research and development programs.[https://archive.today/20140709075406/http://www.nationaldefensemagazine.org/blog/Lists/Posts/Post.aspx?ID=1548 Companies Await Decision on Joint Multi-Role Helicopter Program] – Nationaldefensemagazine.org, 1 July 2014 The demonstrator aircraft will have a lifespan of 200 flight hours, and the Army's budget is $240 million.{{cite news |last=Trimble |first=Stephen |title=Looming FVL demonstrator awards plot uncertain path for US rotorcraft industry |url=http://www.flightglobal.com/news/articles/analysis-looming-fvl-demonstrator-awards-plot-uncertain-path-for-us-rotorcraft-401100/ |work=FlightGlobal |date=22 July 2014 |access-date=24 July 2014|archive-url=https://web.archive.org/web/20140724190144/http://www.flightglobal.com/news/articles/analysis-looming-fvl-demonstrator-awards-plot-uncertain-path-for-us-rotorcraft-401100/|archive-date=24 July 2014 |url-status=live}} In July 2014 the Army decided which two competitors would proceed to Phase One, but will hold program discussions with all four parties to determine a reasonable path forward before announcing the winners,Insinna, Valerie.

On 11 August 2014, the Army informed the Sikorsky-Boeing and Bell-Lockheed teams that they had chosen the SB-1 Defiant and V-280 Valor to continue with the JMR demonstration program. The aircraft designs show the Army is pursuing both coaxial and tilt-rotor designs, and preferring larger and established contractors over the smaller entries. AVX Aircraft says it is still in negotiations with the Army and believes they can still continue with some level of work on the program.

In early September 2014, a panel of aviation experts advised personnel from the FVL initiative how to avoid mistakes made by previous acquisition efforts, namely the F-35 Joint Strike Fighter. The panel had three suggestions: split the program into different manageable pieces; use the expertise of the commercial helicopter industry; and secure early support from the U.S. Congress. FVL is seeking to develop four separate lift classes, which may even become five if the program includes medium lift aircraft for the Navy and U.S. Marine Corps, so the sheer diversity of requirements casts doubt that a single program can successfully produce different versions of a given design.{{Citation |url= http://breakingdefense.com/2014/09/fvl-helicopters-how-to-avoid-f-35-snafu/ |title= FVL Helicopters: How To Avoid F-35 Snafu |newspaper= Breaking defense |date= 8 September 2014 |access-date= 14 September 2014 |archive-date= 14 September 2014 |archive-url= https://web.archive.org/web/20140914223113/http://breakingdefense.com/2014/09/fvl-helicopters-how-to-avoid-f-35-snafu/ |url-status= live}}.

One main problem the F-35 program encountered was having a single program to try to meet different needs with variants of one design. It is possible for FVL to avoid this and still meet it primary goals of using common drive trains, engines, and communications across different helicopters in different services; although the Army's Apache and Black Hawk designs are entirely different, the Marines' UH-1Y Venom utility and AH-1Z Viper attack helicopters have 85 percent parts commonality despite using different airframes. Money and time could be saved by using available technologies from commercial helicopter manufacturers, which was impossible to do with the high-performance F-35.{{Citation |url= http://breakingdefense.com/2014/09/fvl-helicopters-how-to-avoid-f-35-snafu/ |title= FVL Helicopters: How To Avoid F-35 Snafu |newspaper= Breaking defense |date= 8 September 2014 |access-date= 14 September 2014 |archive-date= 14 September 2014 |archive-url= https://web.archive.org/web/20140914223113/http://breakingdefense.com/2014/09/fvl-helicopters-how-to-avoid-f-35-snafu/ |url-status= live}}.

Even though the JSF has secured international partners and FVL has none, partners would be welcomed once the program officially starts, and pre-acquisition industry-to-industry cooperation was advised before government-to-government agreements occur. Congressional support was also advised to be secured early on, as keeping lawmakers in the dark caused lack of trust and imposition of reporting requirements for funding with the F-35.{{Citation |url= http://breakingdefense.com/2014/09/fvl-helicopters-how-to-avoid-f-35-snafu/ |title= FVL Helicopters: How To Avoid F-35 Snafu |newspaper= Breaking defense |date= 8 September 2014 |access-date= 14 September 2014 |archive-date= 14 September 2014 |archive-url= https://web.archive.org/web/20140914223113/http://breakingdefense.com/2014/09/fvl-helicopters-how-to-avoid-f-35-snafu/ |url-status= live}}. As Army Aviation purchase budgets has decreased 40% in 3 years, FVL funding could be conflicting with modernization of the current rotorcraft fleet.{{citation |url=http://www.flightglobal.com/news/articles/opinion-why-us-army-aviation-plans-are-in-a-spin-410842/ |title= Why US Army aviation plans are in a spin |work=Flightglobal |publisher=Reed Business Information |date=8 April 2015 |access-date=9 April 2015 |archive-url=https://web.archive.org/web/20150409145434/http://www.flightglobal.com/news/articles/opinion-why-us-army-aviation-plans-are-in-a-spin-410842/ |archive-date=9 April 2015 |url-status=live}}{{citation |first=Stephen |last=Trimble |url=http://www.flightglobal.com/news/articles/cash-strapped-us-army-aviation-focuses-on-immediate-410730/ |title=Cash-strapped US Army aviation focuses on immediate needs |work=Flightglobal |publisher=Reed Business Information |date=31 March 2015 |access-date=9 April 2015 |archive-url=https://web.archive.org/web/20150409145557/http://www.flightglobal.com/news/articles/cash-strapped-us-army-aviation-focuses-on-immediate-410730/ |archive-date=9 April 2015 |url-status=live}}

In January 2015, the Army confirmed that the FVL-medium category would be split into two different versions, one for attack/reconnaissance and one for utility and troop carrying. Though the program seeks component commonality across the fleet, service leaders identified that different sized aircraft are needed for attack and troop-carrying, so the same airframe may not be used for both missions; other services may also tailor their own FVL-medium variants for specific needs. The versions may even use different forms of propulsion (one tiltrotor and one pusher propeller with coaxial blades), but nothing would be certain until the results of the 2018 TD test flights.{{Citation |url= http://breakingdefense.com/2015/01/army-looks-to-build-two-forms-of-medium-future-vertical-lift/ |title= Army Looks To Build Two Forms of Medium Future Vertical Lift |newspaper= Breaking defense |date= 29 January 2015 |access-date= 1 February 2015 |archive-date= 3 February 2015 |archive-url= https://web.archive.org/web/20150203061059/http://breakingdefense.com/2015/01/army-looks-to-build-two-forms-of-medium-future-vertical-lift/ |url-status= live}}
