Saturn AL-34
{{Short description|Unbuilt aircraft engine}}The Saturn/Lyulka AL-34 was an unbuilt turboshaft/turboprop engine for rotary and fixed-wing aircraft, proposed by the Soviet Union in the early 1990s. In turboprop form, the engine was offered for light aircraft such as the Sukhoi Su-86 eight-passenger business airplane, the Myasishchev M-101T Gzhel business jet, the ROS-Aeroprogress T-101 Grach nine-passenger aircraft, its derivative T-108 Zolotoy Orel nineteen-passenger aircraft, and the Krunichev T-511 "AIST-M". As a turboshaft, the AL-34 was proposed to power the Mil Mi-54 and the Kazan Ansat helicopters. The engine was also considered for unconventional aircraft such as the Mil Mi-30L Vintoplan tiltrotor aircraft, and it was to be an auxiliary engine for powering the boundary layer control system and air cushion on the EKIP flying saucer (a flying wing aircraft).
The AL-34 was one of the few engines to use a recuperator to recover and reuse waste heat from combustion.
The engine came in two versions. The AL-34-1 was an engine that produced {{convert|550|hp}} in cruise conditions. It weighed {{convert|363|lb|kg|abbr=off}}, which included a compact, {{cvt|88|lb}} recuperator. The AL-34-2 was a twin-configuration engine producing {{cvt|1100|hp}}, weighing about {{cvt|1200|lb}}, and using a common gearbox in a single module.
In October 2000, Saturn/Lyulka confirmed that it was still developing the AL-34 engine in the {{cvt|1000|to|1500|hp|kW}} power range, and it was working with Kawasaki on stationary powerplant applications. The AL-34 would cost 200-240 thousand dollars, and it would require about 22 million dollars to complete development. As late as January 2004, the engine was still being proposed for the T-511 "AIST-M" derivative of the Krunichev T-411 Aist light utility aircraft. However, the AL-34 never entered production.
