Embodiment 1

[0033]In 2015, a certain type of refueling pod hose joint stabilization umbrella with variable resistance characteristics was successfully carried out (the area of ​​the umbrella cover is: wind tunnel test, and the test effect is remarkable. According to the outer diameter of the fixed ring of the tanker stabilization umbrella φ262mm and 8 circumferential Design parameters such as M8 threaded through holes, etc., according to the refueling pod hose joint stabilizer umbrella in the real connection state of the aircraft, the stabilizer umbrella joint is designed, and a φ55 size rod balance with M10 threaded holes at both ends is selected. The rod balance is connected by M10 bolts. The stabilizing umbrella joint and the scimitar support rod are connected respectively. The scimitar branch and the scimitar tail support device are connected by nut fastening. In terms of test data, the resistance characteristic test value of the stabilizing umbrella of the refueling pod hose joint: 0.3...

Embodiment 2

[0035] According to the same design idea, a new type of refueling pod joint stabilization parachute force measuring device is established. In 2016, it was successfully applied to the wind tunnel test of a two-type tanker hose joint stabilization umbrella, and the test effect was remarkable. Taking a new type of refueling pod stabilizing umbrella as an example, the designers successfully completed the C-stage selection of this type of umbrella through wind tunnel tests. In terms of test data, the resistance characteristic test value is 0.36m2, and the theoretical value is (0.35~0.40)m2.

Abstract

The invention, which belongs to the technical field of the wind tunnel testing, relates to a force measurement device of a stable parachute of a hose pipe of a pod of an oiling machine. On the basis of the existing rod type scale technology and bent blade type tail boom device technology, a stable parachute joint, a bent blade type support bar, and a rod type balance transfer bolt are designed andare used for forming a force measurement device based on an aerodynamic environment in a real flight state of an oiling pod hose pipe connector stable parachute. The force measurement device has thefollowing advantages: the automation degree and the control precision are high; the technical staff is able to carry out remote control precisely and conveniently; and the test efficiency and safety are improved. With the good support mode, the data deviation caused by the dead load influence of the stable parachute is eliminated effectively; the support interference is reduced; the aerodynamic data of the stable parachute are tested precisely; and the practicability is high. The force measurement device is easy to promote and apply in tunnel testing and has the great practical value.

Description

technical field [0001] The invention discloses a tanker pod hose stabilization parachute force measuring device belonging to the wind tunnel test technology, involving aerodynamics, structural mechanics, testing technology and aviation parachute theory. Background technique [0002] It is understood that several domestic tanker pod hose joint stabilization umbrellas (hereinafter referred to as stabilization umbrellas) all adopt the constant resistance feature technology. With the increasing number of national aircraft types, the demand for multi-type aerial refueling is also increasing day by day. As soon as possible, fill the technical field of variable resistance characteristics, the field of medium and low-speed flight refueling, and the field of refueling and stabilizing parachute for multiple types of helicopters and fixed-wing aircraft as soon as possible. A void is imminent. As one of the important components of the refueling technology, the hose stabilization umbrel...
