FLIGHT International, 2 January 1975 Directory 7 flight in late 1976. The T701 has been tentatively" proposed as an upper-surface-blowing engine for augmentor jet-flap systems. Growth of the T701 is envisaged to 9,500 s.h.p. by increased turbine entry temperature, and to 11,000 s.h.p. via introduction of a compressor zero stage. Model 912 Two-shaft turbofan. Described under its military designation of TF41. T56 Single-shaft turboprop. Described under its commercial designation of Model 501. T63 Two-shaft turboshaft. Described under its commercial designation of Model 250. T70I Free-turbine two-shaft turboshaft. Described under its commercial designation of Model 501-M62. TF41 (Model 912) Two-shaft turbofan. Jointly developed and manufactured by Allison and Rolls-Royce, the TF41 is derived from the RB.168-25R Spey powering RAF and RN F-4M and F-4K Phantoms. The two companies have to date received orders for more than 1,200 TF41s for LTV A-7D (1 X 14,5001b TF41- A-l) and A-7E (1 X 15,0001b TF41-A-2 and -400) Corsair II aircraft for the TJSAF and USN. The A-7D line is financed for the USAF to this year, and the A-7E line for the USN" to 1977, to give a total of 1,387, plus 60 A-7Es to be supplied to Greece. Also flying is an A-7E modified as the YA-7H two-seat trainer prototype. In service, the TF41 has achieved a lower maintenance to-flight ratio and higher rate of life development than any other strike-aircraft engine in the US. Higher-thrust versions of the TF41 are under consideration for a new development of the Corsair II. A fly-off contest between the A-7D and the General Electric TF34-powered Fairchild Industries A-10A in April last year to decide on the USAF's future close-support aircraft is now expected to result in quantity orders for the A-10A. Variable Cycle Engine Allison is one of four companies partici pating in a joint USAF/USN component research programme leading to a variable-cycle Joint Technology Demonstrator Engine (JTDE). Allison has been financed to develop a variable- area h-p turbine, and is expected to develop an associated variable 1-p turbine with its own money. Allied to this, the USAF is supporting Allison in research on a v-p fan, h-p com pressor and high-temperature combustor. Assembly of the complete JTDE is planned for about 12 months' time. DREHER (USA) Dreher Engineering Co. Headquarters: 933 5th Street, Santa Monica, California 90403. Private company engaged in manufacture of aero-engines. The specialist activity of Dreher is to the development of ultra-small turbojets for powered sailplanes and drones. A series of these engines has been built, including the 551b-thrust TJD-76C Baby Mamba, the 1201b TJD-79A Baby Python, and the 1101b TJD-81A Baby Boa. The Baby Mamba has flown in a Prue 215A sailplane. TJD-79A Baby Python. Single-stage mixed flow compressor, annular combustor, single-stage axial turbine. Take-off 1201b, pressure ratio 3:1; length 25-6in; diameter llin; weight 361b. FABRIQUE NATIONALE (Belgium) Division Moteurs, Fabrique Nationale Herstal SA. Corporate head quarters: B-4400 Herstal. Tel: 04 64 08 00. Public company with a wide variety of activities comprising firearms and cartridge manufacture, aero and non-aero gas- turbine manufacture and overhaul, and precision engineering. Corporate sales in 1973-74 down from 1972-73 figure of BFr 3,854 million, £44.5 million, of which the Division Moteurs sales accounted for 20-30 per cent. FN suffered an increased trading loss of BFr46.4 million, * £536,000, in 1973-74 compared with the 1972-73 loss, despite increasing participation in aero-engine work. Manufacturing programmes currently include subcontract work on the Turbo- meca-Snecma Larzao, CFM International CFM56, and Snecma M53. The company is also likely to be a major beneficiary of the fighter re-equipment decision at present pending for Belgium and other Nato countries, FN being the sole aero-engine company among the various European aerospace industries involved. FN is also engaged in overhaul and spares manufacture for Snecma Atars, Microturbo Noelle starters and Boeing 502- 12B ground- starters. FIAT (Italy) Sezione Motori Avio, Aviation Division, Fiat SpA. Divisional headquarters: Gorso Ferrucci 122, Oasella Ostale 343 Ferr. 10100 Torino. Tel: 332 022. Public company engaged in motor vehicle, tractor, iron and steel, diesel engine and aero- and non-aero gas-turbine manu facture. Corporate sales in 1973 up to L2,370,000 million, £1,526 million, of which aero-engine sales represented about 2 per cent. Corporate employees 200,575. Fiat, despite experiencing its first trading loss for 25 years caused by problems on its vehicle manufacturing side, was able to describe its aero-engine activities during 1973 as having "de veloped well." The Aero Engine section, which today constitutes the major part of Fiat's Aviation Division, has supplemented its traditional licensed manufacture of General Electric and Rolls- Royce engines "with participation in three international develop ment programmes—the Turbo-Union RB. 199, the Pratt & Whitney JT10D, and the Rolls-Royce Viper 600 series, the first two of these being in conjunction with Alfa Romeo, with which Fiat also collaborates on licence production of GE engines. This latter activity is supplemented by subcontract manufacture of a wide variety of engine and helicopter gears and gearboxes. With participation in Alfa Romeo's production of J85-GE-13A turbo- jets for the G.91Y at an end, manufacturing activity is currently centred on the J79-GE-19 for Aeritalia F-104S Starfighters and on 120 or so T64/P4D turboprops for 44 Aeritalia G.222 transports now on order. With the growth in business expected from the RB.199 production programme—and possibly also the Pratt & Whitney F100 for the Lockheed/Aeritalia F-204 Lancer—Fiat may be in a position to expand its activities at Nuova SAC A Motori at Brindisi in southern Italy (see below). FLYGMOTOR (Sweden) Volvo Flygmotor AB. Headquarters: S-461 01 Trollhattan. Tel: 0520/301-00. Subsidiary of AB Volvo, a public company with corporate activities comprising manufacture of motor vehicles, marine and industrial engines, agricultural and forestry machinery, aero engines and sundry minor products. Corporate assets Kr8,822 million, £889 million, and employees 51,408. Corporate sales in 1973 up to Kr8,986 million, £905 million, with aero-engines accounting for around Kr290 million, £29.2 million. Current 12-monthly rate of aero-engine sales (April 1973—March 1974) up to Kr319 million, £32.1 million. Flygmotor's main activity is manufacture of RM6 turbojets and RM8 turbofans. Other work includes development of small rocket engines and overhaul and maintenance of military and airline engines, in particular R-R Avon turbojets and P&W JT8D turbofans. Total payroll at Flygmotor on these activities is 2,000. In August 1973 the parent company announced an agreement with Klockner-Humboldt-Deutz, Garrett Corporation and Mack Trucks to develop a 500 h.p. gas turbine for com mercial vehicles as an alternative to diesel engines. Volvo Flygmotor's RM8A and -B provide thrust for the Viggen
