Saturn AL-34

Last updated

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, [1] the Myasishchev M-101T Gzhel business jet, [2] the ROS-Aeroprogress T-101 Grach nine-passenger aircraft, [3] its derivative T-108 Zolotoy Orel nineteen-passenger aircraft, [4] and the Krunichev T-511 "AIST-M". [5] As a turboshaft, the AL-34 was proposed to power the Mil Mi-54 [6] and the Kazan Ansat [7] helicopters. The engine was also considered for unconventional aircraft such as the Mil Mi-30L Vintoplan tiltrotor aircraft, [8] 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. [10]

The engine came in two versions. The AL-34-1 was an engine that produced 550 horsepower (410 kW) in cruise conditions. [2] It weighed 363 pounds (165 kilograms), which included a compact, 88 lb (40 kg) recuperator. The AL-34-2 was a twin-configuration engine producing 1,100 hp (820 kW), weighing about 1,200 lb (540 kg), and using a common gearbox in a single module. [11]

In October 2000, Saturn/Lyulka confirmed that it was still developing the AL-34 engine in the 1,000 to 1,500 hp (750 to 1,120 kW) power range, and it was working with Kawasaki on stationary powerplant applications. [12] The AL-34 would cost 200-240 thousand dollars, and it would require about 22 million dollars to complete development. [13] 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. [5] However, the AL-34 never entered production.

Honeywell T55 Family of turboprop aircraft engines

The Honeywell T55 is a turboshaft engine used on American helicopters and fixed-wing aircraft since the 1950s, and in unlimited hydroplanes since the 1980s. Today, there have been more than 6,000 of these engines built. It is produced by Honeywell Aerospace, a division of Honeywell based in Phoenix, Arizona, and was originally designed by the Turbine Engine Division of Lycoming Engines in Stratford, Connecticut, as a scaled-up version of the smaller Lycoming T53. Both engines are now produced by Honeywell Aerospace, and the T55 serves as the engine on several major applications including the CH-47-Chinook, the Bell 309, and the Piper PA-48 Enforcer. The T55 also serves as the core of the Lycoming ALF 502 turbofan. Since the T55 was first developed, progressive increases in airflow, overall pressure ratio, and turbine inlet temperature have more than tripled the power output of the engine.
