...create window-shattering sonic booms all across the countryside, and possibly even leave enough carbon dioxide in the upper layers of the atmosphere to change the earth's climate. Now Robert T. Jones of NASA'S Ames Research Center, near San Francisco, has suggested a radical new SST design that he claims would overcome most of these objections. It would also be one of the oddest looking planes ever to take...
Jones, a pioneer in the development of swept-wing aircraft, proposes building an SST with a single elliptical-shaped wing that would pivot on the fuselage. During takeoff, the wing would be set at right angles to the fuselage to provide maximum lift. But as the plane approached supersonic speed, the wing would be pivoted by about 45 ° to reduce drag, making the craft resemble a flying pair of scissors...
...delta wings. Thus it could operate with conventional, relatively quiet turbofan jets, sharply reducing noise on landings and takeoffs. It would also prevent pollution of the stratosphere by burning less fuel and by flying at lower jet altitudes (40,000 ft. v. 65.000 ft. for the originally proposed U.S. SST). Finally, unlike other SSTs. it could fly economically at Mach 1.2. At that speed, it would create no sonic boom (under normal atmospheric conditions) and could fly over populated land without causing discomfort and damage below...
...radio controlled subsonic flights. Building a full-scale prototype would be costly and would undoubtedly involve difficult engineering problems, but NASA apparently shares Jones' enthusiasm for the plane. It recently awarded a contract for studies of the antisymmetric design to Boeing, the frustrated contractor for the vetoed American SST...
According to DOT Secretary John Volpe, 50,000 copies of SST-T-T have been distributed to educators as part of the department's Interagency Aircraft
