Snecma-Turbomeca Larzac
The Snecma Turbomeca Larzac is a military turbofan jet engine that the French consortium GRTS ( Groupement Turbomeca - SNECMA ) was developed in the late 1960s. It was selected in February 1972 as a drive for the German - French light fighter-bomber and trainer aircraft Alpha Jet and 1993 as a MiG- ATF - drive.
Development
The French company SNECMA and Turbomeca had founded for the development of the engine in 1968, the consortium MRTS. The first test run of the M49 Larzac took place in 1969. This originally designed for civilian use engine was further developed after the realignment of the military market for Larzac 04- C6, which was selected in 1972 as a drive for the Alpha Jet. From October 1973 until the end of 1975 the flight tests were conducted in the Alpha Jet in Istres granting the authorization. Other milestones included the first flight of the first production Alpha - Jets (November 4, 1977 in Istres ) and the first German Alpha Jets (April 12, 1978 in Oberpfaffenhofen ).
In 1975, a cooperation agreement with the German company Klöckner- Humboldt -Deutz (KHD, Deutz AG today ) and MTU was completed for the series production of the engines. To this was added after the purchase of the Alpha Jet in Belgium or the Belgian FN Partner (now Techspace Aero). This ultimately resulted in proportions of 29.4 % for Turboméca, 23 % of SNECMA, MTU of 22.6%, 22 % of KHD and 4% of FN / Aerospace Tech in the development and production.
The original Alpha Jet engine Larzac 04- C6 was further developed into the uprated Larzac 04- C20 from 1981. This version or the parts kits for the conversion of 04- C6 variants were delivered from 1984. A planned civilian version Larzac 03 to equip the Aérospatiale Corvette was not ready for the market.
Construction
The Lazarc is a twin- engine without afterburner. The low-pressure compressor or fan is on two levels and the four-stage high-pressure compressor, the high pressure and low pressure turbines each stage. All compressor and turbine stages are traversed axially. The engine has an annular combustion chamber.
Use
- Alpha Jet ( two Larzac 04- C6 or C20 - 04 )
- HAL HJT -36 Sitara (prototypes for flight testing with a Larzac 04 -H20)
- MiG ATF ( export version, with two Larzac 04- R20)
