Systematic Wind-Tunnel Measurements on Missiles

Abstract

Investigation of models in wind tunnel was conducted for the purpose of developing a desirable parallel jet, requiring a well-defined nozzle design for each Mach number. Nonrotating missiles were investigated in the range of Mach numbers from 1.2 to 3.2. The wind tunnel operates on the Prandtl principle. A brief stationary air stream is produced in an evacuated tank by induction of atmospheric air. The air in Laval nozzles did not expand adiabatically because of condensation of water vapor during expansion.
