Abstract

An improved technique is proposed to carry out experimental investigations by means of gas-dynamic differential plant. These experiments are intended for comparative studies of several high-altitude nozzles, detailed investigation of non-steady gas flows within nozzles, detection and estimation of factors affecting on a thrust of jet engine nozzles. The kernel of the technique consists in some mediate comparison of two tested nozzles with the reference compensating nozzle. An experimental error is evaluated for various operation conditions of the tested nozzles.
