Abstract
Description
technical field
[0001] 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
[0002] 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.
[0003] 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 r...

Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] 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...
