...highest scoring students also compete individually for prizes of up to $500, but most students said they participate to challenge themselves. Charles M. Kodner '89, who is enrolled in Math 22a, a high level calculus course, said the test was comparable to "jumping off a very high cliff...
...outsize beer barrels draped over a discarded boxcar. But inside each barrel was a three-bladed propeller, and between two of them was a stubby wing. The boxcar fuselage contained some of the most complex machinery in the history of flight. The whole contraption was billed as the X-22A. Bell's contribution to the roster of V/STOL (Vertical/Short Takeoff and Landing) airplanes...
...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...
