AERODYNAMICS.

Abstract

Possible radical advances in aerodynamics that may be introduced by 1990 - 1995 include the introduction of the waverider to attain higher supersonic speeds, the use of suction to maintain laminar flow over sweptback wings of subsonic aircraft in the interests of fuel conservation, and the reintroduction of propeller-driven aircraft also to conserve fuel. Possibilities of evolutionary aerodynamic advances are noted in wing design for subsonic transports, improved high-lift devices, engine nacelles with reduced interference drag and improved noise shielding, and, finally, improved supersonic transports with variable wing geometry.
