It is available new or as a conversion kit for the E4. In US Army service it is known as the H-23F. H23D Raven This is the military counter part of the 12E, powered by a 250 h.p. Lycoming VO-435-23B engine. Deliveries to the US Army began in 1957 for obser vation and training duties. A further $6.6m order received in 1961 is the largest-ever contract for Army light helicopters in peacetime. • Gross weight, 2,7001b; empty weight, Kaman HU2K-I Seasprite 1,8161b; max speed, 95 m.p.h.; cruising speed. 82 m.p.h.; max rate of climb at s.l., 1,050ft/ min; hovering ceiling out of ground effect, 1,250ft; range, 205 miles. Ten99 By taking advantage of the high power-to-weight ratio of the 500 s.h.p. Canadian Pratt & Whitney PT6 shaft turbine, and by mounting it above the cabin, Hiller have produced in the Ten99 the first of a new generation of compact light heli copters of great versatility. The overall dimensions are no larger than those of current light helicopters, yet the Ten99 offers twice the usual passenger capacity, two and a half times the usable cargo volume and nearly double the pay load. Standard seating for six passengers is combined with new features such as aft clamshell doors, four other large doors, overhead cargo hook and an advanced high-lift rotor system. • Length of fuselage, approx. 29ft; height, approx. 10ft; gross weight, 3,5001b; empty weight, 1,9001b. HO-5 Five prototypes of this four-seat lightweight helicopter are under construc tion, to compete against the Bell HO-4 and Hughes HO-6 in the Army's light observation helicopter (LOH) evaluation trials. Like its rivals, the HO-5 has a 250 s.h.p. Allison T63 shaft-turbine engine and will carry a 4001b payload in addition to the pilot and fuel. X-18 Largest tilt-wing aircraft yet flown, the X-18 has been grounded recently for studies of downwash effects on ground environment during simulated hovering in a test rig. Prior to this, it has made 20 flights as a fixed-wing aeroplane, with its wing set at angles of attack of up to 50°. The X-18 utilizes major fuselage assem blies of a Chase YC-122 transport. Two 5,850 s.h.p. Allison T40-A-14 turboprops drive large contra-rotating propellers which would function as helicopter rotors during take-off and landing with the wing tilted vertically. At the same time, the jet efflux from a fuselage-mounted Westinghouse J34 turbojet would be exhausted through deflector nozzles at the tail for pitch control. • Span, 48ft; length, 63ft; height, 24ft 7in; gross weight, 33,0001b; design max speed, 250 m.p.h. Hughes Tool Company, Aircraft Division Culver City, California Model 269A Hughes claim that this two- seat ultra-light helicopter can be flown for a direct operating cost of only $10.65 per hour. It is of all-metal construction, with a steel-tube basic structure and bonded main rotor blades. The 180 h.p. Lycoming O-360-C2E engine uses a vee-belt drive system, eliminating the need for a clutch. FLIGHT International, 7 June 1962 Deliveries have been at the rate of two per day since the end of 1961. • Rotor diam, 25ft; length of fuselage, 22ft 3in; height, 7ft llin; gross weight, 1,5501b; empty weight, 8671b; max speed, 90 m.p.h.; max cruising speed, 85 m.p.h.; max rate of climb at s.l., l,450ft/min; hovering ceiling ;n ground effect, 6,000ft; normal endurance, 3.6 hours. HO-6 Five HO-6 four-seat light observa tion helicopters have been ordered for US Army evaluation at Fort Rucker, Alabama, in competition with the Bell HO-4 and Hiller HO-5. They will each be powered by a 250 s.h.p. Allison T63 shaft turbine. The Kaman Aircraft Corporation Old Windsor Road, Bloomfield, Connecticut H-43B Huskie This helicopter will re main in production until at least July 1963 as the result of a follow-up order for 59 received in November 1961. Meanwhile the aircraft already operational with the Air Rescue Service of MATS at more than 40 USAF bases have achieved an enviable record. In 18 months, they made more than 80 rescue flights and saved the lives of 34 aircrew whose aircraft crashed and burned. Developed from the earlier HOK/ HUK/H-43A series of piston-engined heli copters, the H-43B features the intermeshing rotor system found on all Kaman designs prior to the Seasprite. It is powered by an 860 s.h.p. Lycoming T53-L-1B shaft turbine, mounted above its cabin, and its normal payload consists of a pilot, two fully-clothed firefighters and 1,0001b of firefighting and rescue gear. In other roles, it can carry a crew of two and ten passen gers, or pilot, four stretcher patients and a medical attendant. An H-43B is being used to flight test a set of rotor blades made entirely of glass- fibre. The performance figures below are for a gross weight of 5,9701b. • Rotor diam, 47ft; length of fuselage, 25ft 2in; height, 15ft 6Jin; max gross weight, 8,8001b; empty weight, 4,4701b; max speed, 120 m.p.h.; econ cruising speed, 98 m.p.h.; max rate of climb at s.l., 2,000ft/min; hover ing ceiling out of ground effect, 18,000ft; range, 235 miles. HU2K-1 Seasprite Although the Seasprite departs from the familiar Kaman inter meshing rotor system, it retains the servo- flap control—a small aileron-type flap on the trailing-edge of each blade—which has proved a valuable aid to stability. Design of the Seasprite began in 1957, following an industry-wide competition for a utility helicopter for the US Navy. It is powered by a 1,250 s.h.p. General Electric T58 shaft turbine and is fitted with the latest electronic equipment for all- weather flight, auto-navigation and auto- stabilization. Typical payloads are a crew of two and eleven passengers, four stretchers or equivalent cargo, and it can pick up as many as 14 survivors on air-sea rescue missions. • Rotor diam, 44ft; length of fuselage, 37ft; height, 12ft 5in; gross weight, 7,5951b; max speed, 162 m.p.h.; cruising speed, 127-147 m.p.h.; max rate of climb at s.l., 2,820ft/min; hovering ceiling out of ground effect, 11,200ft; range (standard tankage) 10 per cent reserves, 610 miles.
