...airplane in 1911, built thousands of bombers and fighters in both world wars, and in recent years experimented with a series of novel vertical takeoff and landing craft. But his greatest fame still stems from the mammoth DO-X flying boat built in 1929. It had twelve engines, a wingspan of 157 ft. and a passenger capacity of 169. Uneconomic though it was, the DO-X could fly the Atlantic and was the ancestor of today's even bigger jumbo jets...
...Breguet 941 accomplishes all this with the modest power of four 1,500-h.p. turboprop engines mounted on a 77-ft. wingspan, and two striking innovations. All four engines are mechanically linked to a flexible driveshaft set in the leading edges of the wings. If one or more engines fail, all four of the 941's big 15-ft. propellers continue to spin, powered by the engines still running. In addition, the wings are equipped with outsize flaps that lower to an angle of 105°-about 15° more than the flaps of any conventional aircraft...
Filling the Gaps. Last week a live ringer for the Tin Goose, Aircraft Hydroforming's newly refined Bushmaster 2000, trundled down a Long Beach, Calif., runway and took off over the Pacific on a test flight. The Bushmaster has the 77-ft. 10-in. wingspan, all the lifting power and durability of its venerable predecessor, and the basic structure of the aircraft remains virtually unchanged. "After all," says Hydroforming's president, Ralph P. Williams, "not one Tri-Motor in all these years has ever had a structural failure...
...price tag of $900,000-about a third of the cost of the F-4 Phantoms the U.S. is using in Viet Nam-the Freedom Fighter is a lot of plane. With a razor-thin wingspan of only 27 ft., the F-5 can carry ordnance, including nuclear bombs, weighing up to half of its own 61-ton weight. That makes it, pound for pound, just about the biggest payload carrier of any supersonic plane. So maneuverable is it that pilots claim that "under 30,000 feet, the F-5 can lick anything that flies-no matter how fast...
...Super VC 10 has some radical innovations for a plane its size. It mounts its four engines aft on twin pods attached to the fuselage, much like the smaller two-engine French Caravelle and three-engine Boeing medium-range 727. This design leaves its swept-back wingspan uncluttered, permits slower landing speeds, shorter takeoffs and more dependable lift. For the passengers, there is more comfort: more leg room, improved air conditioning and a considerably quieter ride...
