...quest for diversification, Mr. Mac has been trying for years to break into the ranks of civilian-airplane manufacturers. And he has been repeatedly frustrated. In the late 1950s, he sank $15 million into a four-engine turbojet transport intended to be a corporate plane or Air Force trainer. Nobody would buy it. "That was the time," says McDonnell ruefully, "that old Mac got doodlebugged again...
...unbearable. Not so with the government-owned Canadian National Railways, which last week announced that though it lost $60 million on 1965 passenger service, it has now ordered five of the turbotrains developed by the U.S.'s United Aircraft Corp. Even without roadbed improvements, these lightweight, low-slung, turbojet-powered whizbangs should be able to clip nearly an hour off the present five-hour Montreal-Toronto...
...operate, it must first be accelerated to a speed of several hundred miles per hour by an auxiliary turbojet or rocket engine, or get a lift from a conventional plane. After that, enough air is rammed into the engine's front inlet to set up a pressure barrier that forces the burning gases to escape at the rear, thus providing thrust (see diagram...
After delivering supplies to a space station, say, the scramjet would fire retrorockets, re-enter the atmosphere and fly back to earth. It would be capable of landing at any large airport with the aid of a turbojet engine, which would begin operating at lower speeds after the scramjet engine is shut down and bypassed. A 500,000-lb. scramjet might well be able to carry as much payload into orbit as a 4,000,000-lb. multistage rocket...
...ducted 7-ft. fans that the X-22A uses as props are a futuristic blend of modern metallurgy and plastic engineering-fiber-glass blades with steel cores and nickel edges. The power behind those fans is a Rube Goldberg blend of engineering-four turbojet engines feeding a total of ten different gearboxes. The barrel-like ducts, along with their -big props, can be rotated by separate hydraulic motors. With the ducts horizontal and the props pointing forward, the X-22A should be capable of more than 300 m.p.h. in level flight; with ducts rotated to a vertical position, the ship...
