FLIGHT International, 7 lanuary 1973 69 -«- paoe 66 TURBOMOTORI (Italy) Turbomotori Internationale SpA. Headquarters: Via della Farnesina 269 00194 Rome. Tel: (06) 326 267. Public company owned equally by General Electric, Fiat and Alfa Romeo. Engaged in marketing aircraft turbines. Farmed in 1970, the company co-ordinates the resources of its three parent concerns to meet market requirements for GE gas-turbine aero-engines. Turbomotori has been engaged initially in distributing GE-designed engines and spare parts and in providing service support for GE- powered Italian aircraft. * s.h.p., contingency 1,910 s.h.p.; length 78-7in, maximum > diameter 22-4in, weight 5251b. J Marbore Single-shaft turbojet. This unit powers a variety T of light strike and trainer aircraft and drones. Produc- t tion by Turbomeca exceeds 5,300, and around twice as I many units have been licenc&-built by Teledyne CAE as £ the J69. Applications and projects; Aerospatiale CT.20 (IX 8801b * Marbore n or 1 X 1,0561b Marbore VI); Aerospatiale j Magister (2 X 8801b Marbore II); Aerospatiale Super Magister (2 X 1,0581b Marbore VT); Potez MS.760A Paris I I, II and ni (2 X 1,0561b Marbore VI). I Marbore VI Single-stage centrifugal compressor, annular reverse-flow combustor, single-stage turbine. Take-off J 1,0591b, pressure ratio 3-84:1, mass flow 21-61b/sec, length / 55 • 7in, width 23 • 4in, height 24 • 8in, weight 3831b. MHA Turboshaft. The projected Moteur d'Helicoptere t Arme is a multi-national study aimed at the Franco- German HAF/PAH-2 battlefield helicopter. * TURBOMECA-SNECMA (France) r Groupement Turbomeca-Snecma GRTS. Headquarters: 1 <> Rue Beaujon, BP 37, 75008 Paris Cedex. Joint management company formed as the result of an '- agreement in 1969 on economic collaboration between > Turbomeca and Snecma. The principal objective of the > company is the development of the Larzac turbofan for ( the Dornier/Dassault-Breguet Alpha Jet. Larzac Two-shaft turbofan. The 2,980n>tbrust-04 version of the Larzac has been developed for the Alpha Jet Franco- German trainer, so far its only application. Deliveries of the engine started last year, following military qualification in May 1975 and award of a production contract in ' January 1976. The current order book comprises 168 engines for France, 252 for Germany, 80 for Belgium and another 31 engines for Togo and the Ivory Coast. The German companies MTU and KHD are participating in co-production of the Larzac, with FN in Belgium also having a share. A large export market for the Alpha Jet and its engine is foreseen. By October last year total Larzac test time amounted to around 12,000hr, including more than 4,200hr in the air. The Larzac is licensed in America to Teledyne CAE. Larzac 04 Two-stage fan, four-stage h-p compressor, annular combustor, single-stage h-p and 1-p turbines. Take off 2,9801b, bypass ratio 1-13:1, pressure ratio 10-65:1, length 45in, diameter 23-7in, weight 6391b. TURBO-UNION (United Kingdom) Turbo-Union Ltd Headquarters: PO Box 3, Filton, Bristol BS12 7QE. Tel: 0272 693871. Public company owned 40 per cent by Rolls-Royce, 40 per cent by Motoren- und Turbinen-Union Munchen, and 20 per cent by Fiat. Engaged in management of aircraft tur bine programmes. RB.199 Three-shaft augmented turbofan. The RB.199 is under joint three-company development for the Panavia Tornado multi-role combat aircraft. R-R, with a 40 per cent share in the programme, is responsible for the 1-p compressor, combustor, h-p turbine, afterburner and ducts, and fuel control systems for the main engine and after burner. MTU, also with a 40 per cent share, is responsible for the i-p and h-p compressors, the i-p turbine, inter mediate casing and gearbox, bypass duct, integral thrust- reverser and operating controls. Fiat shares its 20 per cent with Alfa Romeo and Motoravio Sud, and has responsibility for the 1-p turbine and shaft, rear bearing support, jetpipe and variable nozzle. A highly compact design, largely as a result of its three-shaft design and short afterburner, the RB.199 is tailored to suit the divergent multi-role requirements of the Tornado. In particular, it couples a high percentage reheat thrust for combat with low s.f.c. for long-range low-level penetration, By October last year more than 15,000hr running had been completed by 16 bench engines and 51 flight-test units. Four versions of the turbofan have been tested to date: the RB.199-01 rated at less than 90 per cent of the design augmented thrust of 16,8601b and which has been used for the bulk of Tornado flying; the RB.199-02 uprated version giving closer to 90 per cent thrust; the RB.199-03, intermediately rated between the -02 and full design thrust; and the RB.199-04, which is only two or three per cent below design rating. Deliveries of the -04 are imminent, as is completion of the engine's Formal Qualification Test. The production standard engine is the Mk 101, of which 400 have so far been ordered for 150 Tornados. First deliveries of this version are scheduled for May next year. Total planned requirement of RB.199-34Rs for the UK, Germany and Italy's intended procurement of 809 Tornados is over 2,000 units. An uprated engine, of about 17,0001b thrust, is under development for the air-defence variant, which will enter service in the mid-1980s. Twin RB.199 configurations charac terise some proposals for the RAF's AST403 Harrier/ Jaguar replacement, and the powerplant without after burning is also under consideration! for Sweden's projected Saab B3LA trainer/light-attack aircraft. RB.199-34R Three-stage fan, three-stage 1-p compressor, six-stage h-p compressor, annular combustor, single-stage h-p and i-p turbines, two-stage 1-p turbine, close^coupled afterburner with convergent nozzle and thrust reverser; bypass ratio approximately 1:1; pressure ratio in excess of 23:1, mass flow 1541b/sec, length 66-9in, diameter 34-25in, weight 2,2051b. VOLVO (Sweden) Volvo Flygmotor AB. Headquarters: S-461 01 Trollhattan. Tel: 0520 301-00. Subsidiary of AB Volvo, a public company with cor porate activities comprising manufacture of motor vehicles, marine and industrial engines, agricultural and forestry machinery, aero-engines and sundry minor products. Cor- MHF Turboshaft. Being studied by Turbomeca and R-R as a joint venture under government contracts, the Moteur d'Helicopter© Futur is rated in the 1,500-2,000 s.h.p. class. Its intended application is the proposed European tactical transport helicopter planned for the mid-1980s. MHF is understood to embody features additional to those incor porated in the Makila. Turmo Free-turbine two-shaft turboshaft. The Turmo has ratings extending from 1,384 to 1,632 s.h.p. and has been used extensively on Aerospatiale twin and three-engined helicopters. Over 1,800 units have been delivered and pro duction continues. - Applications: Aerospatiale SA.330 Puma (2 X 1,384 s.h.p. , Turmo IIIC4 or Turmo IVB, or 2 X 1,417 s.h.p. Turmo TVA, or 2 X 1,560 s.h.p, Turmo IVC); Aerospatiale SA.321 Super f Frelon (3 X 1,450 s.h.p. Turmo IHC5, or 3 X 1,517 s.h.p. Turmo mC6, or 3 X 1,550 s.h.p. Turmo IIIC7). ? Turmo IIIC7 Single-stage axial plus single-stage centri fugal compressor, annular reversfrflow combustor, two- 1 stage compressor and power turbines. Integral rear- , mounted gearbox. Take-off 1,632 s.h.p., pressure ratio 5-9:1, mass flow 13-71b/sec, length 71-6in, width 27-3in, height i 28-2in, weight 7161b.
