Abstract : A study is presented of the nature of aerodynamic information, particularly of an experimental type, required in connection with future high altitude flight. Correspondingly, the features of experimental equipment required to provide this data are delineated. Emphasis is placed on the blowdown wind tunnel with combustion-fired ceramic storage heater (supply temperature = 3000R) for fluid mechanical information in all ranges of rarefaction; on the shock tunnel for real gas information; and on the combined shock tunnel and wind tunnel for providing test air in chemical equilibrium. The versatility of these systems is stressed. The complementary nature of other types of test facility is pointed out. Some fluid mechanical aspects of the problem of providing uniform low density flows are outlined together with possible means of dealing with the problem. (Author)
