Abstract

A process for testing a full-sized aircraft or full-sized gas turbine engine in a wind tunnel and includes the steps of securing a full-sized aircraft or engine in a wind tunnel for testing; filling an underground storage reservoir with compressed air; passing pre-treated compressed air from the underground storage reservoir through the wind tunnel for testing of the full-sized aircraft or engine; connecting an outlet of the wind tunnel to an ejector; and, passing compressed air from the underground storage reservoir through the ejector to decrease the exit pressure at the wind tunnel during testing of the full-sized aircraft or engine. The step of pre-treating compressed air from the underground storage reservoir includes preheating the compressed air; and, passing the higher temperature compressed air into the wind tunnel.

Claims (14)

1. A process for testing a full-sized aircraft or full-sized gas turbine engine in a wind tunnel comprising the steps of:

securing a full-sized aircraft or engine in a wind tunnel for testing;

filling an underground storage reservoir with compressed air;

passing pre-treated compressed air from the underground storage reservoir through the wind tunnel for testing of the full-sized aircraft or engine;

connecting an outlet of the wind tunnel to an ejector; and,

passing compressed air from the underground storage reservoir through the ejector to decrease the exit pressure at the wind tunnel during testing of the full-sized aircraft or engine.

2. The process for testing a full-sized aircraft or engine in a wind tunnel of claim 1 , and further comprising the steps of:

the step of pre-treating compressed air from the underground storage reservoir includes preheating the compressed air; and,

passing the higher temperature compressed air into the wind tunnel.

3. The process for testing a full-sized aircraft or engine in a wind tunnel of claim 2 , and further comprising the steps of:

the step of pre-treating compressed air from the underground storage reservoir includes preheating the compressed air without lowering an oxygen content of the compressed air to a higher temperature.

4. The process for testing a full-sized aircraft or engine in a wind tunnel of claim 1 , and further comprising the steps of:

the step of pre-treating compressed air from the underground storage reservoir includes passing the compressed air from the underground storage reservoir through an air turbine to lower the temperature of the compressed air; and,

passing the lower temperature compressed air into the wind tunnel.
