Study on Regulating Law of Two-stage Turbo charger System of Piston Aircraft Engine
The power of engine can be recovered at high altitude by matching turbocharger, however, if the mass flow of turbine is not accurate, it will result in under power or boost pressure exceed engine required strength of structure, therefore the mass flow of turbine should be regulated exact.A certain type of piston aircraft engine was selected as a testing engine and its two-stage turbo charger model was built based on GT-Power software and the models effectiveness was demonstrated by a large number of experiments.The regulating law of turbine waste-gate in different operating conditions can be researched by using this model.The results show that the power and the intake air pressure of the engine can be achieved to the design goal within an altitude of 10,000 meters.The regulating law of the turbine waste-gate is the basis for Turbine Control Unit, which is fairly important for the development of piston aircraft engine.
