Abstract

In this paper, the environmental control system of aircraft driven by a power turbine is further analyzed. Through the numerical simulation of the change of the bleed state under different flight conditions and the change of the flow field under different nozzle opening, the simulation results are verified by the experimental results, and the specific change rules of the power turbine output torque, power, and bleed flow are obtained. It is analyzed quantitatively that adjusting the adjustable nozzle ring can keep the output power stable, widen the flight envelope, and improve the stability of the environmental control system.
