FLIGHT, 3 June 1955 759 The F.F.A. P-16 attack prototype, powered by an Arm- strong Siddeley Sap- phire, has now done several hours flying (an in-flight view was published in our May 23rd issue). Points of interest are the almost-flush in- takes, the very thin sharp - edged wing, with large plain flaps and drooping ailer- ons, the twin 30mm Oerlikon 302RK guns and the six wheels. AIRCRAFT INTELLIGENCE U.&A. Boeing 707. Metal-bonded sandwichpanels, with a metal honeycomb in the centre crushed around the edges by aHydro-press, are used in the flaps, inboard ailerons and trailing-edges of this Americanprototype. According to Aviation Week, Boeing are developing a method of machin-ing honeycomb by means of an electrode. Convair F-102A. It is reported that the performance of this all-weather intercepter will shortly benefit from the extra thrust provided by the new Pratt and Whitney J57-P-35. This type of J57 delivers no less than 17,2001b thrust when the afterburner is brought in, an increase of 1,200 lb over the engines at present fitted. Later pro- duction models of the F-102 are to be powered by Pratt and Whitney's forth- coming J75 turbojet, in place of the Wright J67 originally selected. Boeing £-47 Stratojet. Government Air- craft Plant Six, at Marietta, Georgia, which is at present building B-47Es under Lock-heed management, is to manufacture 15 B-47s specially equipped with the MA-2radar bombing system developed for the Boeing B-52 long-range bomber. Desig-nated YB-47J, this Stratojet variant will be employed by Strategic Air Command as acrew-trainer, in order to have fully- or partially-trained crews ready for theB-52Bs as the latter are delivered. Netherlands Aviolanda AT-21. At their works inPapendrecht, the Dutch Aviolanda Com- pany (who also help to make Hunters) havedesigned and built an electronically con- trolled target with this designation. TheAT-21 is built largely of plastics, the nose being of sandwich construction. Power isprovided by a SNECMA-Aviolanda pulse- jet delivering between 100 and 190 lbthrust. The AT-21 has a span of 13ft, a length of almost 20ft and a weight of 660 lb.A special hit-recorder is carried and two parachutes are employed in landing. France S.E. Vampire with Thrust Reversal.Three years ago the S.N.E.C.MA. com- pany demonstrated their Vampire equippedwith a reverse-thrust device of their own design and manufacture. It is knownthat retraction of the characteristic rings has been successfully tested, and that anAtar turbojet has been fitted with the device. S.N.C.A.N. N.C.856. Of 112 N.C. 856A.O.P. machines ordered from S.N.C.A.N. at Bourges, 90 had been delivered by thebeginning of June. One float-equipped model, the N.C.856H, was handed overlast month to Prince Rainier, of Monaco, for his personal use. Czechoslovakia Czech-built Helicopter. The prototype ofa two-seater helicopter has been con- structed by the Czechoslovak industry, andquantity production will begin shortly. The qualities of this machine are said to be"well up to world standard," and the type will be suitable for training and generalpurposes.
