PROJECT SQUID. Semi-Annual Progress Report

Abstract

In connection with Project Squid, a program for the development of liquid-fuel rocket and pulsejet engines, a semi-annual progress report by Princeton University is given. Phase 1 of the Princeton research, as outlined in the initial program report of the Squid Project, is covered. A study of the interaction of boundary layer and shock waves over the rear of airfoils and bodies of revolution, at supersonic Mach numbers, over a wide range of Reynolds numbers is to be performed. The experimental study will at first be concerned with the high Reynolds number range (from two to forty million) for a series of Mach numbers from 1.5 to 5.0. This wide range of conditions will be obtained in a supersonic "blow-down" tunnel, which is operated by a high pressure air supply system, capable of supplying up to 150,000 cu ft of "free" air at pressures ranging from approximately 30 psi to 500 psi abs. The tunnel and its instrumentation are described in detail.
