Scaling of Rocket Nozzle Admittances [PDF]
AIAA Journal, 1974 To apply the admittance data measured experimentally for small-scale nozzles, the necessary scaling criteria must be established. The results of an investigation undertaken to determine these criteria are presented and the data indicate that under cold-flow conditions the damping of axial instabilities provided by full-scale nozzles can be determined ...

Several nozzle concepts that promise a gain in performance over existing conventional nozzles are discussed in this paper. It is shown that signie cant performance gains result from the adaptation of the exhaust e ow to the ambient pressure. Special attention is then given to altitude-adaptive nozzle concepts, which have recently received new interest ...

Fluid flow in rocket nozzles [PDF]
34th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 1998 An analysis is presented to simulate the turbulent compressible flow in converging diverging nozzles using a time-marching finite difference scheme of MacCormack. The Navier-Stokes equations governing the physical domain are transformed to a rectangular computational domain and the resulting equations are cast into finite difference form. The effect of
