On the Design and Use of a Flexible Nozzle for the GALCIT Transonic Wind Tunnel


Dhawan, Satish (1949) On the Design and Use of a Flexible Nozzle for the GALCIT Transonic Wind Tunnel. Engineer's thesis, California Institute of Technology. doi:10.7907/ESYY-5P20.


Some aspects concerning the design of flexible nozzles for use in supersonic wind tunnels are discussed. Methods are investigated for matching the deflection patterns of nozzle plates and the theoretical aerodynamic shapes required for uniform, parallel, shockfree flow. Application of the design procedures to the Galcit 4" x 10", transonic wind tunnel is detailed. As a demonstration of a use of the tunnel, the Mach number of shock detachment from a 10° wedge (half angle) is experimentally investigated.
