Abstract
Provided is a connecting device for a folding wing surface folding gap of a flutter wind tunnel model. The device comprises folding rotating shaft mechanisms (3), an H-shaped limiting element (4), and a fastener (5). The H-shaped limiting element (4) is specifically in an H shape. An end of the H-shaped limiting element (4) is provided with a through-hole structure. The H-shaped limiting element (4) is fixedly connected with a folding wing (1) through the fastener (5) and the through-hole structure. The other end of the H-shaped limiting element (4) is movably connected with a fixed wing (2). The device is light in weight. In a balanced position, clockwise turning gap and anticlockwise turning gap are the same. The device is suitable to be used in a flutter wind tunnel model, and has relatively great economic and social value.
Description
Technical field
The utility model relates to the coupling arrangement in the folding gap of folded surface, and a kind of coupling arrangement of the folding gap of folded surface of flutter wind tunnel model is provided especially.
Background technology
At present, the coupling arrangement in the folding gap of the folded surface of flutter wind tunnel model takes up room greatly, and Heavy Weight, causes testing test result inaccurate.
People urgently wish to obtain a kind of coupling arrangement of the folding gap of folded surface of flutter wind tunnel model.
Utility model content
The purpose of this utility model is a kind of coupling arrangement that is applicable to the folding gap of folded surface of flutter wind tunnel model, make the rotating shaft position of modeling aircraft, and gap length can be adjusted easily.
The coupling arrangement in the folding gap of folded surface of described a kind of flutter wind tunnel model is constructed as follows: folding rotary shaft mechanism 3, I shape locating part 4 and securing member 5; Described I shape locating part 4 is specially I shape, one end of I shape locating part 4 is provided with through-hole structure, I shape locating part 4 is fixedly connected with folding wings 1 with through-hole structure by securing member 5, the other end of I shape locating part 4 is flexibly connected with fixed-wing 2, the end of fixed-wing 2 is plugged in the I-shaped groove of I shape locating part 4, described folding rotary shaft mechanism 3 is positioned at the both sides of I shape locating part 4, but described folding rotary shaft mechanism 3 middle parts are provided with the connecting link of its bending, the two ends of folding rotary shaft mechanism 3 are connected with fixed-wing 2 with folding wings 1 respectively.The effect of described folding rotary shaft mechanism 3 is to prevent folding wings 1 and fixed-wing 2 Plane Rotations.
The thickness of the I-shaped groove of described I shape locating part 4 is greater than fixed-wing 0.1-5mm.
The coupling arrangement in the folding gap of folded surface of described flutter wind tunnel model is when folding wings 1 is when folding rotary shaft rotates, I shape locating part 4 together rotates with folding wings 1, because I shape locating part 4 and fixed-wing 2 tolerance clearances are limited, make the folding wings anglec of rotation limited; The groove size coordinating with fixed-wing by adjustment I shape locating part is carried out adjusting play size.
The I shape locating part 4 of the coupling arrangement in the folding gap of folded surface of described flutter wind tunnel model is simple in structure, processing cost is low, dependable performance during simulation gap, and additional damping not, take up room little, lightweight, when equilibrium position, clockwise, counterclockwise corner gap is identical, is suitable for using in flutter wind tunnel model; There is larger economy and social value.
