FLIGHT International, 26 July 1962 ASIA'S AIRCRAFT INDUSTRIES . . . passengers, but an agricultural version is planned. 0 Max speed, 100 m.p.h.: range, 410 miles. Tchan-Tia-Kou Sailplane Works Shen Yang, near Mukden Quantity production of Polish-designed ABC, Bocian, Jaskolka and Mucha sail planes began at Shen Yang in 1955-56. At about the same time, a design team was formed, under the leadership of Dipl. Ing. J. Niespal of the Polish SZD (experimental glider establishment). The first product of this team, which includes Dipl. Ing. Tchen-Kuei-Wen and Li-Ti-Tiun, is the Lie-Fang No 1, which flew for the first time on May 10,1958. Lie-Fang No 1 One of the main materials used in the construction of this tandem two- seat semi-aerobatic training and cross country sailplane is a Chinese lightweight wood known as "Poton." The design is perfectly orthodox, with a single-spar mid- set wing, plywood-covered fuselage, nose skid, mono-wheel and tail-bumper, and spoilers above and below each wing. • Span, 49ft 2\in; length, 26ft 3in; wing area, 199 sq ft; gross weight, 9251b; empty weight, 5051b; max L/D, 22; min sink 2.6ftj sec at 38.5 m.p.h. INDIA Aeronautical Service! Ltd 31 Chittaranjan Avenue, Calcutta 12 This company is manufacturing for the Indian Civil Aviation Department 56 Ashvini-II and 35 Rohini-I training sail planes. Both types were designed at the Department's Technical Centre under the leadership of Mr S. Ramamritham. Aeronautical Services Ltd have also built many IT-G3 single-seat intermediate train ing gliders based on the Grunau Baby. TS-4 Ashvini-n This tandem two-seat medium-performance training sailplane has been developed to meet the requirements of Indian Civil Aviation Gliding Centres and the National Cadet Corps. It is of all-wooden construction, with a two-spar cantilever high-set wing, DFS-type air brakes and mono-wheel undercarriage. # Span, 58ft; length, 28ft 6in; wing area, 210 sq ft; gross weight, l,102lb; max L/D, 23; min sink, 2.7ft\sec at 36 m.p.h. RG-1 Rohini-I First flown on May 10, 1961, this open-cockpit side-by-side two- seat training sailplane utilizes many compo nents of the Ashvini-II, including the tail surfaces, wingribs and air-brakes. Construc tion is of wood and the two-spar wing is supported by a single bracing strut each side. • Span, 54ft 4in; length, 26ft 9\in; wing area, 223.5 sq ft; gross weight, 1,0891b; empty weight, 6111b; max LID, 21; min sink, 2.79ft\sec at 38 m.p.h. 135 Hindustan Krishak prototype Hindustan Aircraft Ltd Bangalore District Since it was founded in 1940, Hindustan Aircraft has been India's leading aircraft manufacturing company; it also operates extensive repair, overhaul and servicing facilities. Production of the company's first original design, the HT-2 primary trainer, has ended after delivery of a total of 160 to the Indian Air Force, Indian flying clubs and Ghana. Today it is manu facturing the Folland Gnat fighter under licence for the Indian Air Force, and a two- seat lightplane of its own design named the Pushpak. Under development are the Hindustan HF-24, the first supersonic fighter designed and built in Asia, a four-seat development of the Pushpak known as the Krishak, the HJT-16 basic jet trainer and a logistic air support aircraft of which no details are available. In addition to building under licence Bristol Siddeley Orpheus turbojets for its home-produced Gnats, Hindustan is devel oping the 90 h.p. PE-90H flat-four piston- engine for future versions of the Pushpak and a small turbojet (approx 3,0001b thrust) to power its HJT-16 trainer. It holds a licence from Rolls-Royce to manufacture Dart 531 turboprops for the Avro 748s being produced at Kanpur. HF-24 This twin-engined fighter has been developed by Hindustan under the leader ship of Dr Kurt Tank, designer of many wartime Focke-Wulf aircraft. Work on the project began in 1955, to meet an Indian Air Force requirement, and first flight tests of the aerodynamic envelope were made in March 1959 with a full-scale wooden glider. The first prototype HF-24, powered by two 4,8501b thrust Bristol Siddeley Orpheus 703 turbojets, flew in June 1961. It was announced then that the fighter was already in production, but this was clearly optimistic. With its present powerplants, the HF-24 can be no more than transonic and a decision has yet to be reached on the type of engine that will be fitted in produc tion aircraft. Much favoured by Hindustan is a reheat version of the Soviet-built KJimov VK-7, or RD-9, which develops 6,7001b thrust dry. The prototype HF-24 has room for a second pilot, with dual controls, in the rear of the cockpit, but this space will normally be occupied by armament, fuel, cameras or electronic equipment. No details of the armament have been released, but there are two gun ports on each side of the nose. Pushpak Hindustan Aircraft claim to have started construction of the prototype Push pak on August 7, 1958, and to have flown in the following month, on September 28. Nine production models were completed in the 1960-61 financial year and more than 25 had been sold to flying clubs in India by the beginning of this year. The prototype had wooden wings, but production Pushpaks are all-metal. They are powered at present by a 90 h.p. flat-four Continental, but Hindustan hope to replace this eventually by their own PE-90 engine. • Span, 36ft; length, 21ft; height, 9ft lin; wing area, 175 sq ft; gross weight, 1,3501b; empty weight, 8701b; max speed, 90 m.p.h.; cruising speed, 70-85 m.p.h.: max rate of climb at si, 500ft/min; service ceiling, 14,000ft; range, 250 miles. Krishak Powered by a 190 h.p. Conti nental engine, the four-seat Krishak is a multi-purpose development of the Pushpak, suitable for agricultural, casualty evacua tion, AOP and liaison duties, as well as for training and private flying. The first prototype flew in 1959 and has since been joined by a second. PE-90H This simple four-cylinder hori zontally-opposed air-cooled engine is the first practical result of Hindustan's ambi- Indonesian NU-90 Belalangs
