An efficient supersonic wind tunnel drive system for Mach 2.5 flows

Stephen Wolf, James A. Laub, L. S. King

Abstract

A novel efficient drive system has been developed which provides for the continuous operation of a pitot Mach 2.5 wind tunnel at compression ratios down to 0.625:1. The drive system does not require an overpressure to start, and no hysteresis has been observed. The general design of the proof-of-concept wind tunnel using the new drive system and its modifications are described.
