摘要

The outcome of theoretical and experimental research into controlled nozzleblocks with a short length and high degree of expansion which are promising for application aircraft engines with an elevated configuration density are presented. Special attention is focused on plate-type annular nozzles and nozzles with cylindrical and bell-shaped nozzle heads. The issues of shaping the control surfaces as well as the methods of analyzing localized and integral parameters, particularly pressure profiles and rate characteristics and impulse responses, are considered.
