FLIGHT, 11 November 1955 741 AIRCRAFT INTELLIGENCE Great Britain Mixed-Power Intercepters. It is reportedin Italy that two mixed-power intercepters —;one a Saunders-Roe, the other an Avro—will soon make their first flights. One of these machines, it is said, will have a deHavilland Gyron or Gyron Junior and a Spectre, whereas an Orpheus and anArmstrong Siddeley rocket are specified for the other. U.S.A. Piasecki YH-16A. Since this, the world'slargest helicopter, was illustrated in Flight's special Philadelphia Show reports (Sep-tember 16th and 23rd), the tail has been completely revised, now having anhedralhorizontal surfaces and vertical fins at the extremities. FairMd C-119 Flying Boxcar. The last machine of this type—the 1,112th—re- cently left the Fairchild production line at Hagerstown, Maryland. Bell Helicopters. Three gas turbines are the intended powerplants of a 28/36- passenger transport development of the Bell HSL anti-submarine helicopter. Pre- sent powerplant of the HSL is the Pratt and Whitney R-2800 piston engine. Troubles continue to be encountered with the anti- submarine version. Rotor blades of larger diameter are to be fitted. Boeing KC-135. It is intended that thistanker equivalent of the 707 transport shall have a starter on only one of its four turbo-jets. The other three will be started by compressor-bled air from that engineblown into the intakes, thus saving space and weight. Hiller Rocket Helicopter. The destruc-tion by accident is reported of a recently completed Hiller helicopter developed fromthe Hornet but with the ramjets replaced by "oxygenated water rockets." Addi-tionally there was a small piston engine mounted in the fuselage and driving apropeller. The machine is reported to have climbed vertically with the rockets and tohave flown horizontally as an autogiro. It is surmised that "alterations of dynamicstability and insufficiency of directional control" may have been the causes of theaccident. BoeingKB-50. One hundred Boeing B-50bombers are being converted by the U.S.A.F. into KB-50 three-point tankers.They will be employed by Tactical Air Command, T.A.C. having long stated arequirement for multiple-point refuelling for its fighters and fighter/bombers.Hitherto.. KB-29s, equipped with the Boeing flying-boom system, have served.Aerodynamic improvements will add a few knots to cruising speed. Stroukoff MS-S-l. This designation de- Seen in its "anti-atom" finish, the Conyair 6-36 on the left was photographed recently over Kent. A B-36 reconditioning and modifi- cation programme is now under way at Con- vair's Fort Worth plant. Seen below in the new U.S. Navy colour scheme of grey and white is a Chance Vought F7U-3M Cutlass. The missile launchers are clearly seen under the folded outer wings. Note also the slats. notes a forthcoming development of theAvitruc. A "pantobase" transport, it will have turboprop power and boundary-layercontrol. France Nord 1500 Guepard. The name Guepard(Cheetah) has been conferred on the Nord 1500 experimental delta-wing fighter,which made its first flight from Melun/ Villaroche on September 20th. Officiallyadmitted to be "characterized by two sorts of powerplants," the Guepard is under-stood to have a turbojet arranged along the axis of a ramjet. S.E.210 Caravelle. The latest priceunofficially quoted for this twin-Avon transport is $1,857,000 (approximately£664,000). During October the machine was inspected by—among others—Alexan-der Kartyeli and officials of the Republic organization; directors of U.A.T.; Messrs.Gray and Campbell Orde, respectively of the M.O.S. and B.O.A.C; and Dr. Kimura,technical adviser to Japan Airlines. S.N.C.A.S.O. Vautour (Avons). As re-ported in Flight of October 28th, a Vautour all-weather fighter has been fitted with twoRolls-Royce Avon RA.41 turbojets. The thrust of this Avon is now given as 9,925 lb,and it has been disclosed that the particular Vautour is No. 09, one of the six pre-production aircraft being delivered this year. Together with the three prototypes,these machines will serve for operational development work. It is officially statedthat, while endurance tests and armament trials with bombs, guns and missiles arebeing effected with the other prototype and pre-production aircraft, No. 09 will "con-tribute practical information on the be- haviour and performance of the Vautourairframe equipped with high-thrust engines." Deliveries of Vautours to theFrench Air Force will begin in the spring of 1956, but all these machines will bepowered by S.N.E.C.M.A. Atar 101E3 turbojets of 7,720 lb thrust. Potez 75. Having undergone gunnerytests at Cazaux, this twin-boom pusher left Les Mureaux recently for tests in NorthAfrica. The aircraft is now equipped with four machine guns and has provision foreight rocket projectiles. S.N.C.A.S.O. Djinn. The first Djinn helicopter to be sold outside France was delivered recently to a Swiss company. Marcel Dassault Mystere IVA. Somedays ago M. Roger Gromand, Assistant Air Prefect, visited the Cambrai base of theFrench Air Force to witness resumption of flying within the framework of "OperationCormy." This operation had previously been interrupted as a result of a "jet enginefailure." Operation Cormy is described as a stepped-up Service exercise involving allDassault Mystere IVAs powered with the Hispano-Suiza Verdon turbojet. The firstsquadron was equipped with these machines at Cambrai in May this year. Principalobject of the exercise is to determine requirements in spares, supplies and main-tenance of the Verdon-Mystere over a 4,000-hr flying period.
