Summary. Ground effect on lift and pitching moment has been measured on a Comet 3B in flight at one particular value of incidence for the whole range of heights where ground effect is significant. The flight results are ...

A piloted simulation of the take-off manoeuvre of a large aircraft has been developed to aid research into take-offdirector instruments. Records of undirected take-offs made in real flight and on the simulator have been ...

The investigation of aircraft handling characteristics at high angle of attack and high subsonic speeds is hampered by the lack of accurate data on aerodynamic derivatives. The development of a rig and method of test for ...
