The fan rotational speed of a dual axial compressor forward fan engine is the same as the. Low-pressure compressor. Forward turbine wheel. High-pressure compressor. Rear turbine wheel.

The function of the exhaust cone assembly of a turbine engine is to. Collect the exhaust gases and act as a noise suppressor. Swirl and collect the exhaust gases into a single exhaust jet. Straighten and collect the exhaust gases into a solid exhaust jet. Return and throw out the exhaust gases into a solid exhaust jet.

The highest heat-to-metal contact in a jet engine is the. Burner cans. Turbine inlet guide vanes. Turbine blades. Compressor blades.

The non-rotating axial-flow compressor airfoils in an aircraft gas turbine engine, are called. pressurization vanes. stator vanes. bleed vanes. Guides vanes.

The pressure of subsonic air as it flows through a convergent nozzle. increases. decreases. remains constant. is inversely proportional to the volumen.

The pressure of supersonic air as it flows through a divergent nozzle. increases. decreases. is inversely proportional to the temperature. Keeps constant.

The procedure for removing the accumulation of dirt deposits on compressor blades is called. the soak method. field cleaning. the purging process. Treatment against corrosion.

The purpose of a bleed valve, located in the beginning stages of the compressor, in an aircraft gas turbine engine is to. vent some of the air overboard to prevent a compressor stall. control excessively high RPM to prevent a compressor stall. vent high ram air pressure overboard to prevent a compressor stall. Increase low RPM to prevent a compressor stall.

The recurrent ingestion of dust or other fine airborne particulates into a turbine engine can result in. Foreign object damage to the compressor section. The need for less frequent abrasive grit cleaning of the engine. Erosion damage to the compressor and turbine sections. Foreign object damage to the turbine section.

The stator vanes in an axial-flow compressor. convert velocity energy into pressure energy. convert pressure energy into velocity energy. direct air into the first stage rotor vanes at the proper angle. Avoid air flow into the first stage rotor vanes at the proper angle.

The stators in the turbine section of a gas turbine engine. increase the velocity of the gas flow. decrease the velocity of the gas flow. increase the pressure of the gas flow. increase the temperature of the gas flow.

The turbine section of a jet engine. Increases air velocity to generate thrust forces. Utilizes heat energy to expand and accelerate the incoming gas flow. Drives the compressor section. Drives the turbine section.
