Keywords: gas turbine engine, aerodynamic thrust

This first principles methodology enables the direct measurement and calculation of the wind tunnel drag effects acting upon the engine and support structure that are necessary to derive the aerodynamic thrust correction for an indoor test facility, and thus, eliminate the need for open air / free field testing.
