US Supersonic Transport(SST) Program post-1971

PROPULSION TECHNOLOGY ADVANCES NEEDED FOR A QUIET SUPERSONIC TRANSPORT

Operation of a U.S. developed supersonic transport must and will meet community noise standards. This paper examines the airport noise problems of large transport aircraft, highlights critical considerations, and then studies possible solutions available from advanced propulsion technology.

Planform effects on the supersonic aerodynamics of multibody configurations - NASA Technical Reports Server (NTRS)

An experimental and theoretical investigation of the effect of planform on the supersonic aerodynamics of low-fineness-ratio multibody configurations was conducted. Longitudinal and lateral-directional aerodynamic and flow visualization data were obtained on three multibody configurations. The...

Hi! McDonnell DouglasDouglas DC-AST model.

「In the 1990s, NASA restarted development of an American supersonic jetliner, a project started and terminated in the 1960s, under the "High Speed Civil Transport" brand. McDonnell Douglas proposed a 300-passenger quadjet with a range of 5000 nautical miles and top speed as high as Mach 2.4, but never built anything close to a full airframe. That was the second time the company or its predecessors had planned a supersonic jetliner but dropped their proposal, as the Douglas 2229 was not submitted to the FAA in the same project that saw the earlier Boeing 2707 and Lockheed L-2000. McDonnell Douglas's only supersonic planes remained the ones built for the military until the 1997 merger with Boeing, and again their only supersonic planes are military. Maybe we'll get an American Concorde flying some day. In the meantime, there is a large model of the McDonnell Douglas SST designated DC-AST at the National Museum of Transportation in St. Louis, Missouri.」
