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...

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 , 2 , 3, 4, 5, 6, 7, and 8, the jet-flap increase-lift connecting wing system of the present invention comprises a turbofan engine, a wing, a pylon 5 connecting the turbofan engine and the wing, and the turbofan engine has The turbine shaft rectifying cone 3, the wing has trailing edge flaps, the turbine shaft rectifying cone 3 is extended backward for a certain length, and the multi-fish scale type convergent and diffusing nozzle 4 is arranged on it, and there is one on the left and right sides of the outer duct nozzle. For the airflow convergence and diffusion device for the jet flow in the external channel, there is also an airflow convergence and diffusion device for the jet flow in the inner channel on the left and right sides of the nozzle of the inner channel. The airflow converging and diffusing device for the...
