SOME LOW-SPEED PROBLEMS OF HIGH-SPEED AIRCRAFT
Abstract
The low-speed aerodynamics of aircraft shapes suitable for achieving a required range at supersonic speeds are treated. No attention is given to 'slewed' wings, nor to possible application of powered lift or variable geometry. Wind tunnel tests are described on a simplified model with boundary layer control methods applied. Mention is also made of the possibility of adverse ground effect on maximum lift. Work aimed at clarifying some of the requirements for handling qualities of future aircraft are also discussed. Flight tests on an Avro 707A aircraft, with artificially worsened characteristics, are described, and it is shown that substantially constant performance in the piloting task can be achieved at the expense of increased pilot effort. Some tentative conclusions on desirable levels of speed stability and phugoid damping are drawn.
