Problems solved by technology

[0004] Domestic medium-sized aircraft have not yet designed slats, and large-scale aircraft have added slat designs, and require the inspection of the consistency of wing surface motion, but the research and development and application of such products are still in the early stages, and there are no relatively mature products

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0025] The invention relates to a slat tilt detection device for a high-lift system of an aircraft, which can realize the detection of the inconsistency of the movement of adjacent airfoil surfaces of a plurality of side-by-side slats, and transmit the detected signal to the flight control system; ensure that the steel cables are under tension state and self-compensation for the length change of the cable under high and low temperature, wing deformation, etc.; the mechanism itself realizes self-locking; tension limit protection.

[0026] Such as figure 1 As shown, it includes a slat tilt detection sensor 1 and a steel cable 2; wherein, the steel cable 2 is arranged through a plurality of side-by-side slats in sequence, one end is fixed to the outermost slat, and the other end passes through t...

Abstract

The invention relates to a slat tilting detection device of an aircraft high lift system. The slat tilting detection device comprises a slat tilting detection sensor and a steel rope, wherein the steel rope sequentially penetrates through a plurality of parallel slats, one end of the steel rope is fixedly connected with the outermost slat, and the other end of the steel rope is fixedly connected with the innermost slat through the slat tilting detection sensor; the slat tilting detection sensor comprises a fixed support seat, a step cylinder, a sleeve cylinder, a piston, a target and a probe, the fixed support seat is fixedly arranged on the corresponding slat, the step cylinder is fixedly arranged on the fixed support seat, the sleeve cylinder and the piston are sequentially sheathed into the step cylinder, the target is fixedly arranged at the sealing end of the sleeve cylinder, and the probe is fixedly arranged on the fixed support seat corresponding to the target; the probe and the target form a proximity sensor, and the output end of the probe is used as the output end of the slat tilting detection detector; a sleeve cylinder spring is sheathed on the exterior of the sleeve cylinder; one end of the sleeve cylinder spring is connected with the sleeve cylinder, and the other end of the sleeve cylinder spring is connected with a spring clamping boss; a pre-tightening piston spring is sheathed on the part, extending into the sleeve cylinder, of the piston; one end of the piston spring is connected with the piston, and the other end of the piston spring is connected with the sleeve cylinder; the extending end of the piston is connected with the steel rope.

Description

technical field [0001] The invention belongs to the field of aircraft high-lift systems, and relates to the consistency detection and output of detection signals of slat wing surfaces, in particular to a slat tilt detection device for aircraft high-lift systems. Background technique [0002] The high-lift system mainly changes the camber and area of ​​the wing through the downward extension of the slat and the deflection of the flap backward to increase the lift of the aircraft during take-off and the lift and drag during landing, thereby shortening the take-off and sliding distance of the aircraft and improving the aircraft's performance. takeoff and landing performance. When the slat is normally retracted and lowered, the consistency of the movement of the wing surface should be maintained. If the inconsistency exceeds a certain threshold, it will affect the aerodynamic characteristics of the aircraft and reduce the lift-drag effect of the high-lift system during the take-...
