With a blast of newspaper ads last week, Westinghouse Electric Corp. boasted it had "the world's most powerful jet engine qualified for production." The new model of its J40 turbojet, said Westinghouse, produces "more than 25,000 h.p. at flight speeds," will go into the Navy's McDonnell Demon and Douglas Skyray fighters...
Conceived in the wind tunnels and laboratories of Hitler's Third Reich, the delta wing passed its early years as a kind of aeronautical curiosity, something for designers to toy with when they sketched supersonic planes of the future. Then turbojet and rocket experts began to turn out engines that had enough power to shove a man-carrying airplane up toward the speed of sound. The fantastic troubles of high-speed flight changed from drawing-board theory into tough, practical problems...
...Rotor. McDonnell will not tell what its convertiplane will be like. Sky-side gossip believes that it will have a rotor driven by some sort of jet. One possibility is small ram-jets on each blade tip to push the rotor around. Another is a central turbojet engine blowing hot gases through hollow rotor blades. The gas will escape as jets from one side of each blade tip, making the rotor spin. When the aircraft has gained enough altitude, the central engine will be used to propel it forward, supported partly by the windmilling rotor, partly by small wings...
...attraction was the cigar-shaped, swept-wing Hawker P-1067 interceptor-fighter, powered by a Rolls-Royce turbojet and touted as the "fastest fighter in the world." To show what the P-1067 can do, Hawker's chief test pilot, Neville Duke, opened the throttle and snapped his plane low over the runway at 15 m.p.h. faster than the official world record (670 m.p.h.), held by the U.S.'s F-86 Sabre. The whip-cracking sound of its passage hit the crowd like an explosion and knocked a microphone out of an announcer's hand...
...through them by means of a compressor. The air keeps the reactor from overheating. In doing this service, it gets hot itself. It expands enormously and roars out of the other end of the reactor, spinning a turbine that turns the compressor. This is little more than an ordinary turbojet engine with its combustion chambers replaced by a nuclear reactor. After passing through the turbine, the blast of hot air rushes out the tailpipe, while the reaction to the blast drives the airplane forward...
