A STUDY ON THE INDUCED DRAG OF A THRUST-VECTORED JET TRANSPORT ALRCRAFT DUE TO YAWED JET DEFLECTION abstract
The effects of yawed jet deflection changes to the exhaust nozzle angle have been studied for a vectored civil jet transport aircraft to see how the induced drag coefficient and factor of wing-jet combination interact with the yaw jet deflection. As experimental study has been coducted using a low-speed open-return wind tunnel with a closed test-section to test the externally adjustable exhaust nozzles on twin wing-mounted turbofan engines. A discussion of the theoretical and experimental work is given. Both circular and rectangular nozzles provide the jet deflections at various yaw angles ranging from -40 to 40 gegrees. The experimental results were used to fit analytical curves and to obtain suitable equations for the induced-drag factors of the wing-jet configuration.
