ABSTRACT:
A method for controlling the amount of side load experienced by a gas turbine engine and associated airframe components is provided, where the gas turbine engine includes a thrust vectoring system which deflects thrust at a vector angle away from a centerline thereof. The method includes the steps of calculating engine thrust, calculating a side load vector angle limit as a function of the calculated engine thrust and a side load limit, and limiting the vector angle of the thrust vectoring system to the side load vector angle limit in order to maintain operation of the gas turbine engine within the side load limit.
