Abstract : The paper describes an experimental study of the wakes produced by hypersonic cones flying at a velocity of 15 000 ft/s. Three basic cone shapes have been flown; 0.7 in base diameter, 20 deg. included angle cones with sharp and blunted noses, and a 1.0 in. base diameter, 44 degrees included angle sharp nose cone. Because of the complexity of the flow field generated by these cones usually flying at some angle of attack. The experimental study was limited to one set of ambient conditions, a cone velocity of 15,000 ft/s and an ambient pressure of 100 Torr of air.
