UPRATING THE FRONTAL THRUST OF A SPHERICAL GAS-DYNAMICAL RESONATOR-PULSE AMPLIFIER

Calculations were carried out with application of current numerical methods and with the use of scientifi ctechnical developments of a gas-dynamical resonator-thrust amplifi er. The possibility of creating an exit device with a resonator for a small-size gas-turbine engine that in fl ight provides for thrust uprating by no less than 6% via gas mass attachment in the pulsating process is shown. In this way the size–mass characteristics of the exit device are preserved in the process.
