Abstract

The invention relates to a wind tunnel test device, and more particularly, relates to a high-speed wind tunnel unmanned aerial vehicle launching test mechanism. The mechanism is a three-degree of freedom mechanism (in short, a vertical beam and slider mechanism) formed by upper and lower guide rails, a vertical beam, a vernier slider and an attack angle ring, wherein the vertical beam can realizefront-back (X direction) movement along the upper and lower guide rails; the vernier slider can realize up-down (Y direction) sliding along the vertical beam; and the rotary attack angle ring is in charge of setting of the attack angle of a launched object. The device has the advantages of simple structure, accurate simulation, high precision, simple state change and low cost, and particularly, due to the light structure and corresponding small blocking interference, a critical important role is played in correct throwing object load extraction.

Description

technical field [0001] The invention relates to a wind tunnel test device, in particular to a high-speed unmanned aerial vehicle delivery test mechanism. [0002] technical background [0003] When the aircraft is flying, after the drop is launched or dropped from the aircraft, due to the mutual interference between the aircraft and the drop, it will have a great impact on the safe flight of the aircraft. The motion trajectory is simulated for measurement. [0004] There are currently two typical wind tunnel testing techniques that can be used to measure the trajectory of a droplet separating from an aircraft. That is, the free throw technology and the capture trajectory test technology. The advantage of the free drop technology is that it is not interfered by the support system of the external model, and the drop trajectory is close to the real trajectory, but the disadvantage of this technology is also very obvious, and it is very complicated to realize in a high-speed wi...
