AE 325 Gas Turbine Engine Components Quiz

The cold section of a turbine engine includes the air ______ duct and the compressor section.

The first major section of a turbine engine is the air ______.

The engine air inlet is designed to provide a relatively turbulent free supply of air to the face of the ______-pressure compressor or fan.

The design of the intake duct is vital to the performance of the engine under all airspeeds or angles of attack to avoid compressor ______.

Many inlets are shaped to raise the air pressure above atmospheric pressure to achieve ram recovery or ______ recovery.

Convection cooling/film cooling uses compressor bleed air directed in through the hollow blades and out through holes in the tip, leading edge, and trailing edge for blade ______.

The conical fuel spray from the nozzle intersects the recirculation vortex at its center in the ______ section.

Combustion should be completed before the dilution air enters the flame tube, otherwise the incoming air will cool the flame and incomplete combustion will result in the ______ section.

Transpiration cooling is only used on stationary nozzle vanes, where bleed air is ducted into the vanes and exits through the ______ material.

Counter Rotating Turbines are chosen by engine designers for their effectiveness in dampening gyroscopic effects and reducing engine ______, not for aerodynamic reasons.

An electric spark from an igniter plug initiates combustion and the flame is then self-sustained in the ______ section.

A typical exhaust section extends from the rear of the turbine section to the point where the exhaust gases leave the engine, directing the flow of hot gases rearward to prevent ______.

Fuel is supplied to the airstream by different methods. The most common is the injection of a fine atomized spray into the recirculating airstream through spray nozzles in the ______ section.

The exhaust cone assembly consists of an outer duct, an inner cone, radial hollow struts, and tie rods, channeling and collecting turbine discharge gases into a single ______.

A turbine transforms a portion of the kinetic energy in the hot exhaust gases into mechanical energy to drive the compressor and accessories in the ______ section.

The turbine section of a turbojet engine is located downstream of the combustion section and consists of four basic elements: case, stator, shroud, and ______.

A tailpipe is an extension of the exhaust section that directs exhaust gases safely from the exhaust cone to the exhaust, or jet ______.
