BMW production of J79-GE-IIA turbojets. Orenda turbojets The compressor rotors in the foreground belong to Aeromere's F8L Falco, being exhibited by the German and Austrian agent A. Brenner it is exhibiting its products, and particularly the fuel filters installed in the Alouette, Frelon and Super Frelon helicopters. HANOVER SHOW Bristol Siddeley Pegasus lift-thrust ducted fan A. Brenner, Euckenstrasse 2, Munich 25, West Germany. As German and Austrian agent for Aero- mere of Trento, Italy, Brenner are exhibiting the Falco F8L and Superfalco CAR3 two-seat aerobatic and sporting aircraft, exceptionally attractive machines offering excellent perfor- mance on a Lycoming 150 h.p. engine, superb finish and distinctive appearance. Bristol Siddeley Engines Ltd, Mercury House, 195 Knightsbridge, London SW7, England. No fewer than 15 power units are being shown on the Bristol Siddeley stand. They are the Pegasus lift/thrust turbofan; Olympus 301, Orpheus 803, Viper 20 and Viper 11 turbojets; Gnome 1200, Coupled Gnome and Nimbus Rristol Siddeiey Gnome H.I200 turboprop 664 FLIGHT International, 23 April (944 turboshaft engines; BSRJ 824 ramjet; Cumu- lus, Palouste and Artouste turbo compressors" and Gamma 301, Stentor and PR37 rocket engines. The Pegasus has been flying successfully for more than two years in the Hawker P. 1127 VTOL strike aircraft. A number of these machines have been ordered by the British, American and German governments for joint tactical trials, and the British government has announced its decision to order the Hawker P.I 145 Mach 2 VTOL fighter, which is powered by the similar but more powerful BSIOO engine. Key feature of the Pegasus is the use of four movable jet nozzles—directed downward for lift, backward for thrust, forward for braking, or in any intermediate direction. Used ia combination with pure lift engines, the Pegasus can provide at its most economical throttle setting all the propulsive thrust necessary for conventional flight and, at take-off and land- ing, contribute its maximum thrust to meet the VTOL requirement. A turbojet in the highest thrust class, the Olympus powers all marks of Avro Vulcan bomber. A supersonic version, the Olympus 22R, has been chosen to power the British Aircraft Corporation's TSR.2, the new tactical - strike/reconnaissance aircraft on order for the British Royal Air Force; a civil derivative of . this engine—the Olympus Mark 593—is being developed in collaboration with the French aero-engine manufacturers, SNECMA, for the Anglo-French Concord supersonic airliner. ; Orpheus engines have already flown in ten different aircraft types excluding flying test . beds. Most powerful production version is the Orpheus 803 of 5,0001b thrust, which powers ? the Fiat G-91. The Viper 20 is a development of the Viper 11. It powers the Hawker Siddeley 125 and - has also been specified for the Piaggio-Dougla* 808 Vespa-Jet executive aircraft. The principal difference between the two engines is that the . Viper 20 incorporates an additional stage on the front of the compressor. The Viper 11 powers the Macchi MB 326 and is manufac- tured under licence in Italy by Piaggio & C. All Hunting Jet Provost trainer aircraft and Jindivik target drones are fitted with Vipers • Gnome HI200 turboshaft engines are in quantity production for the British Ministry of Aviation and are to be the standard power unit for all the Westland Whirlwinds of the Royal Air Force now in service in the Far East, Middle East and Germany as well as in the United Kingdom. Gnome engines also power the Italian Agusta Bell 204B ten-seat general purpose helicopters and have, in addition, been fitted to the twin-engined Vertol 107 helicopters of the Swedish armed forces; They are also specified for the large three- engined Agusta 101G and the Westland SR.N3 and SR.N5 Hovercraft. The Coupled Gnome is in production for the Westland Wessex Mk 2, and the similar Wessex Mk 5 Commando helicopter for the Royal Navy. A free turbine engine with a shaft drive, the Nimbus is in quantity production for the
