818 WORLD AERO-ENGINE INDUSTRY Snecma's main series-production engine continues to be the Atar turbojet for Mirage fighters, a situation which has pre vailed virtually throughout the company's history; approxi mately 3,750 Atars have been built. Also in series manufacture is the CF6-50 turbofan for the A300, for which Snecma under takes about two-thirds of the work, including assembly and test. Scheduled to enter quantity production is the Larzac, manufacture of which is being shared with Turbomeca, MTU and KHD. Overall, 1973 was expected to show a continuation of the rising sales curve of 1972, and an increase of ten per cent was anticipated. Thereafter in 1974, a falling-away was forecast, reflecting reducing export sales of the Mirage. This trend is likely to have been reversed since the issue of the company's 1972 annual report. For the future, the M45H turbofan for the VFW 614 is entering small-scale manufacture, shared with Rolls-Royce, and hopefully the Olympus 593 for Concorde will be the recipient of further orders, as well as representing an im portant item in Snecma's R&D programme. The most exciting project for the future is the CFM56 ten-tonne turbofan being shared with General Electric. The first runs of this unit at GE and Snecma are scheduled for the second half of this year. On the military front, the M53 turbofan is advancing steadily as a successor to the Atar series, and will power the Mirage F.1E and Avion de Combat Futur. The prototypes of these aircraft should fly this year and in 1976 respectively. The M53 is the only wholly Snecma, wholly French-financed engine under development by the company. Earlier this year, Snecma increased its capital from Fr231-11 million, £19-83 million, to Fr261-77 million, £22-46 million. This resulted in the French Government's holding in the company increasing from 81-6 per cent to 83-7 per cent. SOLOV1EV (USSR) In the transport engine sector, Soloviev is Russia's most suc cessful bureau, and is prominent also in the large-helicopter turboshaft field. Three Soloviev commercial turbofans are in production, and are extensively used in Tupolev and Ilyushin transports. They are the D-20P, D-30P and D-30K, spanning 11,9051b to 26,4001b, the D-30 series having effectively displaced the Kuznetsov NK-8 turbofan in the Tu-154 I1-62M-200. It is conceivable also that the Soloviev bureau was the design originator of the Ivchenko/Lotarev D-36 turbofan for the Yak42. An earlier intention to power the forthcoming 11-86 with an updated D-30KP has recently been cancelled (no doubt because of an escalating thrust requirement), and Soloviev and Lotarev are competing to design a larger unit with a presumably higher bypass ratio. Kuznetsov, Russia's "big engine" bureau, is evidently not participating. The 5,500 e.h.p. Soloviev D-25V turboshaft powers a trio of large Mil helicopters. SURVOL (France) Survol Sari. 30 Chemin de la Roubine, 06-Cannes-La Bocca. M C. Fauvel, designer of tailless sailplanes, and a collaborator, M E. de Coucy, have developed a small 55 h.p. horizontally- opposed piston engine for powering self-launching sailplanes. TELEDYNE (USA) Teledyne CAE and Teledyne Continental Motors Aircraft Products, Division of Teledyne Incorporated. Teledyne CAE Divisional Headquarters: 1330 Laskey Road, Toledo, Ohio 43697. Tel: (419) 475-4641. Teledyne Continental Motors, Air Products Divisional Headquarters: PO Box 90, Mobile, Alabama 36601. Tel: (205) 438-3411. Division of public company engaged in electronics, control systems, aerospace and materials manu facture. CAE is engaged in aero- and non-aero gas-turbine manufacture, and Continental Motors manufactures a wide variety of piston engines for aero- and non-aero duties. Cor porate assets $1,230 million, £512 million, and employees 54,000. Corporate sales in 1973 up to $1,455 million, £581 million, of which aero engine sales represented a minor proportion. Teledyne CAE, which has built well over .10,000 turbines, mainly for unmanned applications, defines its marketing activities as being "concentrated in applications for small and medium-size gas turbines under 15,0001b thrust and 5,000 h.p." As such the company has had major successes in powering large numbers of Teledyne Ryan Firebee and other drones with its J69 and J10O turbojets, and these powerplants con stitute its main business today. The emergence of remotely piloted vehicles as major new weapons in the US armoury has usefully broadened the company's potential market. How ever, Teledyne's earlier near-monopoly position in the "un manned" engine sector is now being contested by other US manufacturers, including GE, AiResearch, Williams Re- FUGHT International, 20 June 1974 ALSPI FRENCH GOVERNMENT 9 PER CENT 50 PER CENT UNITED AIRCRAFT 80 PER CENT 11 PER CENT SNECMAT>J CONCORDE ENGINES CFM56 INTERNATIONAL c CFM56 turbof a 22,000lb D GENERAL ELECTRIC ( CF6 50 turbofan for \ f V^Airbus Industrie ASOOBy ^ ^RnlSUPPORT ORGANISATION IPERCENT 50 PER CENT GROUPEMENT TURBOMECA SNECMA 23 PER CENT < M49 Larzac tu 2,300lb 5,400lb rbofan ~\ Olh ) TEL CF6-50 tu 49,000lb5 68 PER CENT MOTOREN UND TURBINEN UNION Q c F6- 50 components II— 10PER CENT irbofan *\ I.OOOlby1 M53 turbofan 12,3501b 18,7001b FABRIQUE NATIONALE ROLLS-ROYCE TURBOMECA /^M45HanclM45SD rbofans ),072lb ROLLS ROYCE I IVI^iJi 1 (31 1U JVI ( turbofaf \J,760lb 10,t Adour turbofan 5,000lb-9,405lb Adour afterburner J ( Olympus 593 "N turbojet L 38,050lb 40,000lb/ Atar 08 and 09 turbojets J 1,0001b 15,4001b search and United Aircraft of Canada. To expand its product range both for its traditional markets and also into the "manned" engine field, Teledyne in late 1972 acquired the US rights to the Turbomeca-Snecma Larzac turbofan. After nearly two years without an application this powerplant (designated Model 490) may be selected to re-engine the Rock well International T-39A, thus representing yet another in stance of a modern turbofan displacing an earlier vintage turbojet, in this case the Pratt & Whitney J60. Continental Motors ranks with Lycoming as a major inter national supplier of light piston engines for the general aviation market. Continental, whose engines power the majority of Cessna models plus a high proportion of Beech- craft aircraft, has diverged from Lycoming by appointing a licensee (Rolls-Royce Motors) to be responsible for a large slice of the globe outside the Americas, and by developing a new generation of technically advanced units, the Tiara series. The latter has not emerged with quite the success and impact hoped for, but undoubtedly represents an investment which will prove its worth in the long term. Together, the traditional range of Continental units and the new Tiara family cover a power bracket of 90 to 450 h.p. As a temporary setback, Continental Motors suffered a partial shut-down earlier this year before concluding a fresh three-year labour agreement with the United Auto Workers union. THERMO-JET (USA) Thermo-Jet Standard Incorporated. Headquarters: PO Box 1528, Kerrville, Texas 78028. Tel: (512) 367-2148. This company produces a family of valveless pulse-jets for RPVs and home-built aircraft. Four units are being marketed at present covering a thrust range of 211b to 901b, suitable for use at speeds up to Mach 0-8. TUMANSKI (USSR) One of Russia's leading military engine bureaux. Tumanski produces, among other units, the R-ll and R-13 afterburning turbojets spanning 13,6701b to 14,5501b. These power such air craft as the MiG-21 series, and are being licence-built by Hindustan Aeronautics.
