Abstract

The invention provides a trailing edge jet-propelled vector propelling deformable wing. The deformable wing comprises a rigid box section, an elastic box section and a driving mechanism. A pipeline arranged in the rigid box section can conduct high-pressure airflow generated by an aircraft engine to a driving mechanism distributed in the wing elastic box section; a hollow bent pipe of the drivingmechanism can conduct high-pressure airflow to the rear edge of the wing, and the high-pressure airflow is sprayed out from the rear edge of the wing at different angles to generate thrust, so that the purpose of distributed vector propulsion is achieved. Meanwhile, the driving mechanism can drive the elastic box section to deform, the wing form is changed, and the aerodynamic efficiency, stall attack angle limit, lift coefficient and flight performance are improved.

Description

technical field [0001] The invention relates to the technical field of aircraft wings, in particular to a trailing edge jet vector propulsion deformable wing. Background technique [0002] Both manned and unmanned aerial vehicles are widely used in military and civilian fields. The aircraft mainly relies on the wing to generate lift in the directional air flow field, and the lift coefficient and drag coefficient of the wing vary with different airfoils. according to. The engine thrust system is usually external and set independently from the wings. Under the condition of given airflow speed, the wing generally adopts two ways to change the lift force to achieve maneuvering flight. One is to change the angle of attack; the other is to change the deflection angle of the control surface or the camber of the wing airfoil. Traditional configuration aircraft usually change the angle of attack of the wing by manipulating the deflection angle of the tail to change the pitch angl...
