Auxiliary Power Unit (APU) Test Cell
 Auxiliary Power Units provide a source of energy to start the main engines in most jet aircraft, military vehicles, rockets, and spacecraft. In addition, the APU can provide a supply of energy to non-propulsion systems when the main engine is non-operational.
Testing of such equipment is essential to ensure the reliability and functionality of the APU. In a typical test scenario, engineers ignite and power up the APU with different conditions to verify that thrust generation, fuel consumption, vibration, and other operational characteristics are conforming to design.
Engineers isolate APUs, which are high-powered engines, in a special cell of the test facility away from control equipment and personnel for operational safety.
A typical APU test facility manages hundreds of process signals and transducers. These signals relate to the control and measurement of engine fuel, power, and speed.
