138 N-58 Cygnet, by Nihon University ASIA'S AIRCRAFT INDUSTRIES stage fan will be in line with the turbine and driven by exhaust gases in the main engine, but will be mechanically indepen dent. It is designed to offer a 40 per cent increase of thrust compared with the J3, with no increase in fuel consumption. J3-IHI-3 The original J 3-1 version of this simple single-spool axial-flow turbojet was developed by Nippon Jet-Engine Co, which was formed in 1953 by a group of manufacturers including Mitsubishi, Ishi- kawajima, Kawasaki and Fuji. The pro gramme was taken over by Ishikawajima- Harima in 1959 and their improved YJ3 prototype engine was flown for the first time in the Fuji T1FI trainer in 1960. As a result of successful flight tests of this aircraft, a production batch of 20 J3- IHI-3 turbojets was ordered and the first of these was delivered in April 1962 to power the production version of the T1FA for the JASDF. The other 19 are scheduled for completion by November. The J3-IHI-3 has an eight-stage steel compressor, annular combustion chamber with 30 burners and a single-stage turbine. Its pressure ratio is 4.2 : 1 and air mass flow 49.51b/sec. • Max dia, 28.35in; overall length, 72.85 in; dry weight, 8151b; weight with accessor ies, 9481b; max rating, 2,6451b thrust; s.f.c, 1.05. Kawasaki Kokuki Kogyo Kabushiki Kaisha (Kawasaki Aircraft Co Ltd) 38 Akashi-machi, Ikuta-ku, Kobe Like most other Japanese companies, Kawasaki re-entered the aviation industry by undertaking the overhaul of USAF aircraft, followed by licence manufacture of US designs. Since 1955, it has produced 210 Lockheed T-33A jet trainers and more than 150 Bell 47 helicopters. Production of the latter is continuing and Kawasaki is also building 54 Lockheed P2V-7 Nep- tunes for the JMSDF, of which the first 14 were assembled from US components. It is a major sub-contractor to Mitsubishi in the F-104J Starfighter programme and FujiT/F2(TIA) will assemble the last eight of ten Vertol 107 helicopters which it is importing as Boeing's Japanese licencee. As a follow-on to its successful KAQ-1 piston-engined target drone, it is now developing the rocket-powered KAQ-5. Another current project is the MAT (TATM-1) anti-tank missile. KAQ-5 This is a high-speed target drone powered by a slow-burning solid-propellant rocket motor manufactured by Dainihon Celluloid Co. It has a high-wing aeroplane configuration and is designed to be air- launched from a T-33A, with parachute recovery. Guidance is by a self-contained, pre-programmed system and a miss-dis tance indicator is available. The present contract from the Japanese Defence Agency is for two prototypes and an evaluation batch of nine drones. • Span. 6ft 3in; length, lift Win; height, 3ft; gross weight, 3751b; weight after burn out, 2201b; cruising speed, M.0.8 at 35,000ft; endurance, approx 8min. MAT (TATM-1) MAT is a conventional wire-guided anti-tank missile for use by infantry and from helicopters. It is powered by a two-stage solid-propellant motor pro duced by Dainihon Celluloid Co and Prince Motors Co. Control is by spoilers on each wing, via push-button control box. A two-man firing team is required. More than 400 test versions have been produced to date, and it is hoped to have MAT operational next year. • Span, 2ft; length, 3ft 3in; body dia, 5in; gross weight, 34lb; mean speed, 190 m.p.h.; range, 1,970yd. Nihon Kokuki Seizo Kabushiki Kaisha (Nihon Aircraft Manufacturing Co Ltd) Daido Building, No 46, 1-Chome, Minami- Sakumacho, Shiba, Minato-ku, Tokyo NAMC was formed in 1959 to take over from the Transport Aircraft Development Association responsibility for Japan's YS-11 national medium-range transport project. Its capital was subscribed jointly by the Japanese Government and the private companies which had established TADA. YS-11 Scheduled to fly this summer, the "AiRevicw," Tokyo, photograph FLIGHT International, 26 July 1962 YS-11 is a 52/60-seat turboprop transport of conventional low-wing monoplane lay out. Two prototypes are being built by NAMC, each powered by two 3,060 h.p. Rolls-Royce Dart RDa.10/1 Mk P542 engines, plus two further airframes for static testing. Production will be divided between the six private companies (Fuji. Japan Aircraft Manufacturing Co, Kawa saki, Mitsubishi, Shin Meiwa and Showa) which have an interest in NAMC. Fifty- four YS-lls are to be built between 1963 and 1966, according to present plans, for All-Nippon Airways (25), Japan Air Lines (about 10), the Japanese Defence Agency (10), the Maritime Safety Agency (2 for ASR) and the Meteorological Agency (four for weather observation). • Span, 105ft; length, 86ft 3\in; height, 30ft; gross weight, 50,2651b; empty weight (equipped), 31,9701b; max cruising speed at 20,000ft, 296 m.p.h.; econ cruising speed at 20,000ft, 288 m.p.h.; max rate of climb at s.l., l,520ft/min; service ceiling, 27,500ft; t.o. field length (SR422B), 2,900ft; landing field length (SK422B), 3,790ft; range wuh max fuel and 5,4001b payload, with reserves for 230-mile diversion and 45min stand-off, 1,485 miles; range with max payload, same reserves, 380 miles. Nihon Hikoki Kabushiki Kaisha (Japan Aircraft Manufacturing Co Ltd) No 32, 3-Chome, Choja-Machi, Naka- Ku, Yokohama This company is engaged mainly on overhaul of US Navy aircraft and of the 60 Grumman Tracker anti-submarine aircraft of the J MSDF. It built the mock-up of the NAMC YS-11 and is responsible for the design and production of compo nents for this transport. Under JASDF contract, Japan Aircraft Manufacturing Co has also carried out a lengthy high-lift research programme with a much-modified Saab-91B Safir. In its latest form, with the designation Z1G3, this aircraft has a 260 h.p. Continental IO-470-D engine, reduced span of 31ft 6in, blown flaps, large trailing-edge fillets, slotted tailplane and other changes to give it STOL performance. Nihon University, College of Science and Engineering Surugadai-Machi, Chiyoda-ku, Tokyo The students of this university, under the leadership of Dr Hidemasa Kimura, have designed and built two light aircraft. The first was the Okamura N-52 low-wing monoplane, which flew on April 7, 1953. The second is a high-wing four-seat light- plane known as the N-58 Cygnet. N-58 Cygnet Although the Cygnet bears a close resemblance to the Piper Tri-Pacer, it is a new design utilizing existing Tri-Pacer components only in its undercarriage, engine mounting and control systems. Construction is all-metal, with fabric covering, and it is powered by a 140 h.p. Lycoming O-290-D2 engine. • Span, 35ft 2in; length, 22ft llin; height, 8ft 9in; wing area, 185 sq ft; gross weight, l,950lb; empty weight, l,256lb; max speed, 117 m.p.h.; econ cruising speed, 93 m.p.h. at 6,600ft; stalling speed, 42 m.p.h.; rate of
