34 TURBINE ENGINES OF THE WORLD macchi KN-2 derivative of the MB.326. First flight of the Alpha Jet is planned for October this year, with series pro duction to begin in 1976. Larzac-04 Two-stage fan/l-p compressor, four-stage h-p com pressor, annular combustor, single-stage h-p and 1-p turbines. Take-off 2,9001b; pressure ratio 10-65:1; length 45in; diameter 22in; weight 5841b. Teledyne CAE JlOO (USA) Single-shaft turbojet. It is designed for drone applications involving operation at alti tudes of up to 80,000ft and speeds of up to Mach 105. The initial model is rated at 2,7001b, with a later version being uprated to 3,0501b. J100-CA-100 Three-stage compressor, annular combustor, two-stage turbine. Take-off 2,7001b; mass flow 451b/sec; pressure ratio 6-3:1; length 48-2in; diameter 24-7in; weight 4301b. Teledyne CAE Model 490 (USA) Two-shaft turbofan. A pro posed licence-built version of the Snecma/Turbomeca Larzac series for RPVs and drones. Versions are the 2,3001b Model 490-1, 2,4701b Model 490-2, 2,7601b Model 490-3 and 2,9651b Model 4904 (corresponding to the Larzac 04). As primarily the sector providing power units for trainers and light strike aircraft, it contains two of the most exten sively manufactured turbojets of recent years, the J85 and Viper. Having proved themselves in the critical role of trainer engine, these two units in their later, more powerful versions continue to be specified, even though they may be heavier and less economic than their more recent turbofan competi tors. Proven durability, reliability and, above all, cost are the reasons why they are still chosen. In Continental Europe, Czechoslovakia, France and Ger many are developing a fresh generation of trainer engines, but of turbofan configuration, namely the AI-25 and Larzac. The latter is also being licensed to Teledyne CAE in America as the Model 490. In both cases these engines are effectively the successors to earlier quantity-built centrifugal turbojets of lower thrust (the M 701 and Marbore), a combined total of 7,000 to 8,000 of which have been produced. Up to 2,5001b, IlkN TJ125 EtJ331^x^ Edair;| Cougar M701 TRS12 TRS18] J69 J402^\ - -J Marbore Arbizon;. J400 WR2-6 WR19^^| WR24-7 ZJ i i I I I 1 2,5001b Alvis/Kover TJ125 Minijet (UK) Single-shaft turbojet. Its sole application is in the Belgian MBLE Epervier surveillance drone. The Minijet is a two-speed engine with double-datum governor to reduce speed before the landing of the radio- controlled Epervier. TJ125 Minijet Single-stage compressor, annular combustor, single-stage turbine. Take-off 1141b; mass flow 2-051b/sec; pressure ratio 3-9:1; length 22in; width 10-6in; height 12-lin; weight 391b. FLIGHT International, 4 January 1973 Garrett AiResearch ETJ331 (USA) Single-shaft turbojet. A low-cost expendable engine which was developed (in competi- • tion with the Teledyne CAE J402) to power the McDonnell Douglas AGM-84A Harpoon anti-ship missile. The Teledyne engine has now been chosen for this missile. Microturbo Cougar (France) Single-shaft turbojet. The Cougar has an application in the Government Aircraft Factories Turana target drone under development for the Australian Navy. Initial acceptance trials at sea were com pleted last autumn. Basic rating of the Cougar is 1321b thrust for a weight of 58 -41b. There is also the 1981b-thrust Eclair turbojet used as a booster for sailplanes such as the Fauvel Aile Volante AV45, AV46 and AV48, and the Caproni Vizzola Calif A-21J. Motorlet M-701 (Czechoslovakia) Single-shaft turbojet. As the only Czech turbojet, the M-701 has been built in large numbers to power the L-29 Delphin trainer. M-701C-500 Single-stage compressor, tubular combustor, single-stage turbine. Take-off 1,9621b; mass flow 37-31b/sec; pressure ratio 4-3:1; length 81-4in; width 35-3in; height 36-5in; weight 7281b. Sermel TRS 12 (France) Single-shaft turbojet. It is designed for remote telemetered control of starting, thrust level and shut-down, and is suited to missile and drone application. The TRS 12 is rated at 1441b and the TRS 18 at 2201b. The latter engine has also been installed as a booster in the Calif A.21J sailplane. TRS 18 Single-stage compressor, annular combustor, single- stage turbine. Take-off 2201b; length 24-2in; diameter 12in; weight 661b. Teledyne CAE J69 (USA) Single-shaft turbojet. Based on the Turbomeca Marbore and Gourdon turbojets, the J69 has both drone and manned-aircraft applications. Well over 10,000 engines have been built. Current applications include the 1,0251b J69-T-25 in the Cessna T-37B, 1,7001b J69-T-29 in the Teledyne Ryan BQM-34A subsonic drone, 1,9201b J69-T41A in a special-purpose aircraft, and the 1,9201b J69-T406 in the BQM-34E and -F supersonic drones.
