Khlystun O. Aerodynamic and heat exchange processes in transport aircraft hermetic cabins simulations

The work is directed on the energetic consumption reduce and improvement of the comfort in the hermetic cabins of modern transport aircrafts under air conditioning. It is demonstrated the necessity of system approach to transport aircrafts air conditioning equipments development. The model of the her-metic cabins dynamic thermal regimes is presented; the inside inverse problem solution of their heat ex-change is received. The results of the hermetic cabins thermal protection mathematical simulation are pre-sented, an algorithm for jet protection against water condensation designing is proposed. It is received the cabin ventilation simulation problem solution, which accounts viscous, turbulent, non isothermal charac-ter of flow. Aircraft automatic pneumatic valves method of simulation is presented, the damping charac-teristics of the valve pneumatic actuator are determined experimentally by its free motion measuring.
