Abstract
A test facility provides high temperature, high pressure and high mass flow fluid to a test object to form a relatively large thermal gradient on the object. Energy in the fluid is recuperated to drive system components, such as a heat exchanger and a turbocharger compressor. A test chamber housing the test object can be arranged to conform to a contour of the test object. A control system permits independent variation of pressure, temperature, cooling fluid and fluid velocity, as well as mechanical loading on the test object. Noncontact, optical inspection measurement techniques can be employed to measure test chamber and/or test object parameters. The test object can be configured to direct cooling airflow to permit various temperature or pressure gradients to be implemented. The test facility is relatively inexpensive to operate and provides a significant cost advantage over testing conducted in a full gas turbine engine.
