The invention provides a variable-configuration short-distance take-off and landing unmanned aerial vehicle based on upper surface blowing lift augmentation and a method. The variable-configuration short-distance take-off and landing unmanned aerial vehicle comprises a variable nose module and an unmanned aerial vehicle body, when the variable nose module is located in the original position, the short-distance take-off and landing unmanned aerial vehicle is in a wing body fusion layout; and when the variable nose module uplifts forwards and upwards in place relative to the unmanned aerial vehicle body, the short-distance take-off and landing unmanned aerial vehicle is in a canard type layout, so that the configuration conversion of the short-distance take-off and landing unmanned aerial vehicle between the wing body fusion layout and the canard type layout is realized. According to the short-distance take-off and landing design based on the principle of blowing lift augmentation and jet flow control on the upper surface of the aircraft body, variable layout conversion between a canard layout and a wing body fusion layout is achieved through simple actuation of the aircraft head, the take-off and landing distance can be remarkably shortened, meanwhile, more excellent hovering and wrestling performance is obtained, and the aircraft is suitable for being popularized and applied. And meanwhile, the variable layout design fuses aerodynamic advantages of various overall layouts, and various technical indexes of the aircraft can be remarkably improved to meet future combat requirements.
