File Picture of High-Altitude Test Facilities

Gas Turbine Research Establishment (GTRE) has initiated the process to conduct High-Altitude Tests for its Kaveri Engine after it cleared technical audit conducted by French Aerospace engine maker Safran. GTRE recently issued tender asking High-Altitude Test Facilities to send in their proposals which can offer their facilities to test Kaveri engine.

High-Altitude Test Facilities allow Experimental engines to be tested in a test cell which simulates altitude and speed conditions. High-Altitude Test Facilities usually are capable of testing Experimental engines up to Mach 2-3 and can also simulate altitudes up to 75,000 feet.

Cells in such facilities can provide engines sub-zero inlet temperatures which can mimic harshest of the takeoff conditions. Such facilities are also used to explores the altitudes at which an engine relight is possible in case of sudden shut down of the engines.

As per Technical Audit report of Safran, Kaveri engine has been cleared for limited flight envelope trials which means the engine is now cleared for aircraft integration. Kaveri engine in 2017 was tested for 155 hours in endurance mode and performed very well in the Ground test rigs and after analyzing the data collected by Safran cleared the engine.
