Abstract
This note reviews the fundamental principles of the Schlieren method and describes the design and construction of the Schlieren system built for the DREV Hypersonic Range No. 5. This system is designed for detection of the shock waves and wake instabilities associated with a model travelling at hypersonic velocities in a rarefied atmosphere. It is composed of five stations each of which is capable of taking a short exposure (0.5 microsecond) Schlieren photograph or of being equipped with a high-speed framing camera capable of taking 18,000 Schlieren photos per second. The Schlieren system sensitivity has so far permitted detection of shock waves and wake instabilities behind 2.7 inch spheres travelling at 14,500 feet per second at pressures as low as 1.2 torr.
