8 February 1957 181 AIRCRAFT INTELLIGENCE U.S.A. Re-engined Boeing B-52. A version of the eight-jet Boeing B-52 Stratofortress powered with Pratt and Whitney J75 engines (each of 15,000 lb thrust approxi- mately) in place of the present J57s (10,000lb approx.) is being developed by Boeing with the endorsement of Strategic Air Command. Hughes Model 269. The model 269 is a new Hughes helicopter—a two-seater weighing 850 lb empty, having a cruising range of 170 miles at 75 m.p.h. and powered with a four-cylinder Lycoming O-340-A1A engine. Main rotor diameter is 25ft. Aviation Week reports that U.S. Army interest has progressed to the point of "processing an order for an evaluation quantity'—five to ten of the copters." Canada DHC-4 Caribou. Now known as the Caribou, the DHC-4 is already the subject of American and Canadian orders. Two prototypes will be built to meet the require- ments of the Canadian Army and seven machines are being acquired for the U.S. Army, which Service was granted exemp- tion from its 5,000 lb limit as the machine is considered to be a "cargo" type. A 2|/3-ton payload is reported, and landing and take-off runs should be about 500ft. Although the eventual use of turboprops is being studied, Pratt and Whitney piston engines will be initially installed. The undercarriage is of nosewheel type. France Fouga Magister. Following demonstra- tions in the U.S.A., the Grumman Aircraft Corporation has taken an option on a licence to construct the Fouga CM-170R and CM-175 versions of the Magister jet trainer. These models are for land and naval use respectively. Negotiations have also been under way in Germany and in other European and Middle East countries. Having regard to this widespread interest, Air Fouga, in agreement with the French Air Ministry, are said to have adopted measures intended "through a distribution of licences and co-operation programmes, to establish a construction project in France and abroad for approximately a thousand Magisters." Leduc 022. Since its flight on December 26, this supersonic ramjet research aircraft has made about ten flights with the SNECMA Atar D.3 turbojet in operation.A French news report states: "After solving all the utilization problems regard-ing this jet engine installed for the first time at the inside of the thermo-propulsive pipe,a new series of flights will be undertaken with the pipe ignited. Even at the presentdate, the performance of the aircraft during take-off and landing, carrying more than75 per cent of the maximum weight, is more or less identical to the performances ofpresent French fighter planes." An Hispano HA-11J2-M1-L (Me 109 develop- ment) of the Spanish Air Force. The engine is a Rolls-Royce Merlin 500-45 driving a four- blade Rotol aincrew. Note the streamlined rails for a total of eight R.Pt. S.E.210 Caravelle. The second prototypeof the Caravelle twin-Avon transport has now made over 54 flights, totalling 200 hr.It has been fitted out for tourist class travel with 70 seats, and a noise level of 84 deci-bels is reported to have been recorded in the cabin. This compares with 85 decibelsfor a luxury American car of Cadillac type. The machine is now in the workshops atToulouse before its American tour, scheduled for next May. Poland Record Flights. It is learned that onDecember 28 last a TS-8 Bies trainer, fined with a WN-3 engine of 320 h.p.,established a new international height record for light piston-engined aircraft byachieving an altitude of 7,200 metres (23,620ft). The pilot was A. Ablamowicz.Previously the record was held by a Russian Yak-18, with a height of 19,790ft.On December 27 the same pilot had taken a CSS-12 prototype (this machine is a twin-engined transport) to 21,653ft, carrying a load of 2,240 1b. The height record estab-lished on the Bies is the first international record ever put up by a Polish aeroplanefitted with an engine of Polish design. The Bies—several prototypes of which are nowflying—is in large-scale production for the Polish Air Force and for club use.
