Airplane Engine Test Stand

Supplying Power and Air Compression for Specialized Equipment.

Spencer Bristol Engineering, a Gray company, worked with an aviation industry leader to design electrical power distribution and air compression systems for a new airplane engine test stand.

Airplane Engine Test Stand

Spencer Bristol provided MEP design engineering and contract administration services for the customer’s new airplane engine test stand. To conduct testing, the stand required high-pressure, dry, heated air supplied by a 700 HP air compressor, an air dryer, a 1 MW heater, and booster compressors of 350 HP and 120 HP.


Project design included a new 480V, 1600A switchboard for electrical power distribution to the air compressors, as well as the installation of a new 600A breaker into an existing switchboard to power the air heater.


Project services:

  • Conceptual, schematic, design development, & contract documents
  • Field engineering
  • Contract administration


Key features:

  • Chilled water HVAC
  • Series air compressor design to simulate flight pressures
  • Heated dry air to simulate internal combustion conditions
  • New electrical service & distribution board
