INVESTIGATION OF THE PROPAGATION OF GAS FLOW OUTGOING FROM A GAS TURBINE ENGINE UNDER THE MAIN ROTOR AND THE INFLUENCE OF IT ON THE STATE OF AIR AROUND A SINGLE-ROTOR HELICOPTER,

Abstract

Models of a helicopter rotor and the outlet of a gas turbine engine were used to study the propagation and washing out of gas jets beneath the rotor. Tests were also carried out directly on a helicopter, and the results are compared with those of the model tests. Discharging the gas depends greatly upon the operating conditions of the helicopter and the speed of the wind about it. The temperature fields of the air and the gas concentrations in the space below the rotor are unstable. (Author)
