FLIGHT International, 25 July 1963 135 excess of hover capability, by using normal take-off and landing runs. It has a standard Lycoming VO-435 engine and Model 47 rotor system, but the angle of the rotor mast can be varied in flight—a feature introduced by Bell on two previous research helicopters. Span of the Wing Ding is 25ft, with a 15 US gal fuel tank attached to each wingtip. Conventional flaps and ailerons are fitted, and a controllable elevator has been added. The ventral fin is a fixed surface, and the tail rotor is standard. The four-wheel landing gear is fitted with toe-operated brakes. Bell test pilots have made steep helicopter- type descents in the Wing Ding, taken off and landed with forward runs and flown cross-country at 100 m.p.h. They report that the addition of wings causes no loss of efficiency in hovering flight. Model 413-1 Ranger There is no change this year in the Ranger, which is a stream lined member of the 47 family with 305 h.p. (derated to 260 h.p.) Lycoming VO-540-B1B engine, metal rotor blades and powered controls. The pilot sits centrally, and the rear bench seat for three passengers can be folded up to provide a clear space for cargo, or removed to make room for two stretchers plus a jump-seat. Removal of the port door and a trap permits use of an internal powered hoist for rescue missions. Furnish ing can be to utility or de-luxe standards, and either skid or pontoon landing gear can be fitted. Rotor diam, 37ft l±in; length of fuselage, 32ft 4\in; height, 9ft 3$in; gross weight, 2,850/b; empty weight, i,730tb; max speed, 105 m.p.h.;*max cruising speed, 93 m.p.h.; max rate of climb at s.t., BQOftjmin; hovering ceiling in ground effect, 9,200ft; max range, 260 miles. UH-13R Known formerly as the HUL-1M, this is basically a Model 47J re-engined with a 250 s.h.p. Allison T63-A-3 turboshaft. Two have been built for US Navy evaluation, and the first flew in February 1962. Gross weight, 2,850/b; empty weight, 1,3501b; max speed, 105 m.p.h.; max rate of climb at s.l., over 1,300ft/min; hovering ceiling out of ground effect, 9,400ft; range with 1,1701b pay load, 200 mites. UH-IB Iroquois This nine-seat utility helicopter has been in production for the US Army for two years. Early models have a 960 s.h.p. Lycoming T53-L-5 shaft-turbine, but those now being delivered have an 1,100 s.h.p. T53-L-11. In an ambulance role the UH-IB can carry three litters and a medical attendant. Sixteen UH-lBs are being delivered to No 9 Sqn RAAF, for search and rescue, casualty evacuation, reconnaissance and logistic support for 'be Australian Army. Under contracts announced last month, 55 are to be built for the USAF in 1963-64, and many more later, for ICBM site support duties. Like the earlier UH-1A, the UH-IB is operating in a close-support role in Vietnam, with a pair of electrically-controlled 0.5in Suns mounted on each side of its fuselage. Sixteen were delivered to the US Army for evaluation as missile-carriers, with six ™.I1 missiles slung from outrigger booms, and Ford are developing a 40mm grenade- launcher suitable for nose mounting. The Performance data are at a weight of 6,6001b. Uf^"""' 44ft: len*th of fuselage. 39ft 7 in: height, •m 7i n; gross weight, 8.5001b: empty weight. 4,5021b; Bell UH-ID Iroquois max speed, 138 m.p.h.; cruising speed, 126 m.p.h.; max rate of climb at s.l., 2,350ftjmin; hovering ceiling out of ground effect, 12,500ft; max range, 253 miles. UH-ID Iroquois First flown on August 16, 1961, the UH-ID utilizes the same 1,100 s.h.p. T53-L-11 engine and rotor system as the UH-IB, but has a lengthened cabin and increased fuel capacity. Reloc ation of the fuel tanks has helped to make room for a pilot and 12 troops, or six stretchers and a medical attendant. One of the seven YUH-1D development aircraft set up a 1,000-km Class Eld closed-circuit speed record of 134.93 m.p.h. and two Class El time-to-height records in 1962. Series production is scheduled to begin this year. UH-1E Bell are building more than 100 assault support helicopters (ASH) for the US Marine Corps under this designation. The first flew in February. The UH-1E is generally similar to the UH-IB, but has a personnel hoist, rotor brake and special navigation and communications equipment. It will replace the Cessna O-IB and O-IC aeroplanes and Kaman OH-43D helicopters. Model 204B Bell's commercial version of the UH-IB was certificated by the FA A on April 5. Standard powerplant is the 1,100 s.h.p. Lycoming T5309A turboshaft. VHF radio is standard; optional extras include a wide range of radio aids, dual controls, external cargo hook, heater and stretchers. Fuji are producing the 204B in Japan under sub-licence from Mitsui & Co. Agusta in Italy are producing a version designated AB 204-B (q.v.). Rotor diam, 48ft; length of fuselage. 48ft I'm; height. 14ft 6in; gross weight, 8,5001b; empty weight, 4,6001b; cruising speed, 120-138 m.p.h.; rate of climb at s.l., 1,600ft/ min; hovering ceiling out of ground effect, 2,400ft; range, 230 miles. Model 533 Under US Army contract, Bell have modified a UH-IB into a research vehicle on which to evaluate drag-reduction techniques and alternative rotor systems. The aircraft flew for the first time on August 10, 1962, and has achieved speeds of up to 188 m.p.h. in a shallow dive. Design changes include the use of a tilting rotor shaft, cambered vertical stabi lizer and aerodynamic fairings on the fuse lage. Rotor systems tested to date include the standard UH-IB two-blade rotor, and both gimballed and rigid three-blade rotors, with each of which level speeds in excess of 173 m.p.h. have been attained. Future plans for the 533 include the addition of wings and two Continental J69-T-9 turbo- jets. OH-4A This small four-seat helicopter will compete with the Hiller OH-5A and Hughes OH-6A for US Army contracts worth an estimated $200m for approxi mately 3,600 light observation helicopters (LOH). Each company was awarded a contract for five prototypes for competitive testing. First to fly, on December 8, 1962, was Bell's first OH-4A, built with produc tion tools and jigs in less than 13 months from contract and two months ahead of schedule. Few details are available, except that the OH-4A is powered by a 250 h.p. Alli son T63 turboshaft and is designed to carry a pilot and over 4001b of payload at more than 115 m.p.h. It will be able to carry armament for close-support duties. Bensen Aircraft Corporation Raleigh-Durham Airport, Raleigh, NC B-8 Series The basic B-8 Gyro-Glider rotor-kite provided at least the inspiration for a high proportion of the ultra-light autogyros now flying throughout the world. In its unpowered form it can be built and flown by almost anyone, without a licence, in either single-seat or two-seat configura tion. The B-8W Hydro-Glider is the same thing on floats, towed by a motor-boat instead of a car. During the past year, the original round-bottomed floats have been superseded by flat-bottomed wood and Styrofoam pontoons giving better planing and less spray. Third variant is the B-8B Gyro-Boat, in which the basic rotor sys tem is mounted inside a small dinghy to produce a true flying boat. The B-8B takes off at 23 m.p.h. and lands at 7 m.p.h. Some idea of the popularity of the B-8 series and its powered development, the Gyro-Copter, is given by the fact that Bensen have sold over 1,500 completed rotor blades, plus 900 semi-finished and 5,000 in kit form to customers in nearly every country. B-8M Gyro-Copter The first Gyro-Cop ter, produced by Igor Bensen in 1955, was little more than a Gyro-Glider fitted with a target-drone engine, pusher propeller, fuel system and throttle. Continuous refine ment has led to the current B-8M, a really practical little single-seat autogyro powered by a 72 h.p. McCulloch 4318E four-cylin der two-stroke. It can be bought complete, in kit form or as a set of plans from Bensen or from the British agents, Campbell of Hungerford, Berks. The range of optional extras has been extended considerably in the past year and now includes a floor control column instead of the normal overhead stick, rotor spin- up gear, nose-wheel arrester to prevent
