You might know your reciprocating engine well, but how about jet engines?

1. 1) This particular component of an axial flow turbine engine is an integral part of the engine that helps reduce the chances of compressor stall from occurring.

   Variable stator vanes help to reduce compressor stalls of a turbine engine by regulating the airflow into the compressor section. Closing these stators will help reduce the load placed on the low pressure compressor which will help reduce an engine from surging.

2. 2) Turbine aircraft provide a _______ source from the engine in order to allow certain equipment to work such as packs, anti-ice and air turbine starters.
   

   Usually, there is a low pressure and a high pressure pneumatic bleed source that is tapped from the compressor section of the engine. This bleed is source is essential for various aircraft components.

3. 3) What would you most likely see on an accessory gear drive?

   An accessory gear box is located on the side of each aircraft engine. The AGB is directly connected to the N2 shaft, which when on, drives the accessory gear box. This accessory drives oil pumps, integrated drive generator (AC electrical power) and other various components.
