The Diemech TP 100 is an American turboprop and turboshaft aircraft engine that was under development by Diemech Turbine Solutions of DeLand, Florida in 2012.{{cite news|url = https://www.avweb.com/air-shows-events/is-there-room-for-a-240-hp-turbine/|title = Is There Room For A 240-HP Turbine?|accessdate = 27 March 2012|last = Bertorelli|first = Paul|date = 26 March 2012| work = AVweb|archive-url= https://archive.today/20201224164550/https://www.avweb.com/air-shows-events/is-there-room-for-a-240-hp-turbine/|archive-date= 24 December 2020|url-status= live}}{{cite web|url = http://www.diemechturbines.com/TP100.htm|title = TP Turboprop 100|accessdate = 27 March 2012|author = Diemech Turbine Solutions|author-link = |date = 2010|archive-url = https://web.archive.org/web/20120810140121/http://www.diemechturbines.com/TP100.htm|archive-date = 10 August 2012|url-status = dead}}
By June 2017 the company website had been taken down and it is likely that the company is out of business and engine development ended.{{cite web|url= http://www.diemechturbines.com/|title= Company|access-date= 15 December 2020|author= Diemech Turbines |work= diemechturbines.com|year= 2015|archive-url= https://web.archive.org/web/20170610082147/http://www.diemechturbines.com/|archive-date= 10 June 2017|url-status= dead}}
Design and development
The TP 100 was developed from an engine developed by PBS Velká Bíteš of the Czech Republic for use in UAVs. The design goal was to provide an engine that could run on globally available fuels, such as Jet-A or ultra-low-sulfur diesel, given the disappearance of avgas in most parts of the world.
The TP 100 develops {{convert|241|hp|kW|0|abbr=on}} and weighs {{convert|125|lb|kg|0|abbr=on}} plus accessories. The engine was expected to produce a specific fuel consumption of 0.82 lb/hph (0.5 kg/kWh), yielding a cruise fuel flow of {{convert|21|u.s.gal}} per hour which would have been 52% more than the equivalent piston engine, the Lycoming IO-540, which produces the same power at a SFC of 0.45, burning {{convert|12.7|u.s.gal}} per hour. In examining these numbers AVweb editor Paul Bertorelli stated that this "illuminates the harsh fact that turbine engines just aren't as efficient as piston engines and the smaller the turbines are, the less efficient they are".{{cite news|url = https://www.avweb.com/insider/sun-n-fun-redbird-flies/|title = Sun 'n Fun: Redbird Flies|accessdate = 14 March 2012|last = Bertorelli|first = Paul|date = 29 March 2012| work = AVweb|archive-url= https://archive.today/20201224164432/https://www.avweb.com/insider/sun-n-fun-redbird-flies/|archive-date= 24 December 2020|url-status= live}}
The company had planned to work with PBS to obtain Federal Aviation Administration certification in the US. The engine was expected to fly first in mid-2013 on a Van's Aircraft RV-10 testbed, but development ended before the engine was flown.
By 2022 PBS Velká Bíteš was offering the TP 100 for sale as the non-certified PBS TP100 Turboprop Engine "for small aircraft and unmanned aerial vehicles".{{cite web|url= https://www.pbsaerospace.com/aerospace-products/engines/turboprop-engines/ts-100-turboshaft-engine|title= PBS TP100 Turboprop Engine|access-date= 17 May 2022|author= PBS Velká Bíteš|author-link= PBS Velká Bíteš|work= pbsaerospace.com|year= 2022|archive-url= https://archive.today/20220517135401/https://www.pbsaerospace.com/aerospace-products/engines/turboprop-engines/ts-100-turboshaft-engine|archive-date= 17 May 2022|url-status= live}}
