Effect of Side Jets in a Supersonic Flow Measured and Calculated on a Flat Plate and a Generic Missile Configuration

摘要

An investigation on side jets in an M = 5.0 flow was conducted on a flat plate as well as on a generic missile configuration. Surface pressure measurements, oil flow visualisations, force measurements and associated numerical simulations gave insight into the interaction of different jet configurations and their influence on the efficiency of side jet control described by the amplification factor. The analysis of the data especially in the wake of the jet showed that the low pressure region is much less dominant than assumed and that the position of the side jet nozzle is vital also with respect to the exploitation of a desired amplification of the side jet thrust.
