Jet flap lift augmentation connecting wing system and aircraft applying same

Abstract

The invention discloses a jet flap lift augmentation connecting wing system, comprising a turbofan engine, a wing, a hanging rack and a turbine shaft rectifying cone, wherein the wing is provided witha trailing flap; the turbine shaft rectifying cone extends backwards by a length and is provided with a multi-scale convergent diffusion spray pipe; two air flow convergent diffusion devices, which separately consist of an outer front edge and two external convergent diffusion sheets, are respectively arranged at the left side and right side of an outer duct spout; two air flow convergent diffusion devices, which separately consist of an inner front edge and two internal convergent diffusion sheets, are respectively arranged at the left side and right side of an inner duct spout; the wing isa connecting wing; the jet flap lift augmentation connecting wing system can generate a resultant force of upward lift forces when vertically taking off and landing; the jet flap lift augmentation connecting wing system can generate a thrust force and a lift force when executing horizontal cruising flight. The invention discloses an aircraft applying the jet flap lift augmentation connecting wingsystem; the aircraft can realize vertical taking off and landing, high-speed flight as well as smoother conversion between high-speed flight and vertical taking off and landing.

Description

[0001] This application is a divisional application of an invention patent application with application number: 2015104991667, invention name: jet-flap high-lift connecting wing system and its aircraft, and application date: August 14, 2015. technical field [0002] The invention relates to a jet-type external blowing flap increasing-lift system, in particular to a jet-type flap increasing-lift connecting wing system and an aircraft using the jet-type flap increasing-lift connecting-wing system. Background technique [0003] There are two kinds of known jet-type external blowing flap lift-increasing systems, the one is the jet-type upper wing surface blown flap lift-increasing system, and the other is the jet-type lower wing surface blown flap increase-lift system. [0004] The jet-type upper-wing-blown flap lift system can accelerate the jet flow of the jet engine to accelerate the flow of the airflow on the upper wing surface. The flow is also powered up on the upper surfa...

Problems solved by technology

[0004] The jet-type upper-wing-blown flap lift system can accelerate the jet flow of the jet engine to accelerate the flow of the airflow on the upper wing surface. The flow is also powered up on the upper surface of the wing, the jet velocity is high, and the noise and vibration caused by the scouring of the upper wing skin are large; the jet temperature is high, so the upper wing skin and the The ablation of the wing structure is serious, and the requirements for the skin and wing structure are high. Another disadvantage is that the engine jet velocity is high and the noise is loud during takeoff and landing.

[0005] The jet-type lower wing blowing flaps increase lift system can make the jet flow of the jet engine pass through the trailing edge slats of the wings to accelerate the airflow on the upper wing surface of the wing. , and the high-speed jet flow of the jet engine flows through the lower surface of the wing at a short distance during the cruising stage, which reduces the air pressure on the lower surface, reduces the lift coefficient, and makes the cruise efficiency of the wing low; another disadvantage is that the engine High jet speed, loud noise
