Abstract
The present disclosure relates to off-grid testing of a gas turbine engine using an undersized load compressor as part of the testing apparatus. By lowering the pressure experienced by the gas turbine engine at its intake and/or exhaust, validation testing can be performed at the gas turbine's maximum combustion temperature and/or maximum cycle pressure ratio without exceeding the power output that the load compressor is able to absorb. Subsequently introducing compressed air from the load compressor into the combustor of the gas turbine engine allows for surge margin testing to be performed.
