Problems solved by technology

However, due to the possible large influence of atmospheric turbulence in the soft refueling process, the influence of the refueling drogue by the atmospheric turbulence and the head wave effect of the refueling machine, the success rate of one refueling is very low; in addition, the refueling pipe- The drogue produces complex dynamic characteristics, which has a major impact on the control of the oil receiver and even the flight safety of the oil receiver and receiver
At this stage, although some dynamic modeling and simulation research work has been carried out on the dynamic characteristics of the aerial refueling hose-drogue sleeve, the dynamic aerodynamic characteristics of the refueling hose-drogue sleeve are not well understood

Abstract

The invention provides a test device for the dynamic characteristics of a low-speed wind tunnel aerial refueling hose-taper sleeve. The device comprises a refueling pipe, a refueling taper sleeve, a refueling pipe supporting mechanism, a refueling pipe movement mechanism, a fuel receiver model, a fuel receiving taper pipe, two high-speed cameras and PIV (Particle Imaging Velocity) equipment, wherein the refueling pipe is installed on the refueling pipe supporting mechanism; the refueling pipe supporting mechanism is installed on the rotary table of the refueling pipe movement mechanism; refueling pipe movement equipment is controlled to move to drive the refueling taper sleeve to move; when the refueling taper sleeve is near the head of the fuel receiver model, the position of the refueling taper sleeve is regulated to enable the refueling taper sleeve to be connected with the oil receiving pipe; two high-speed cameras collect each piece of test data in a connection process; and the PIV equipment is started to collect bow wave effect data in the connection process of the refueling taper sleeve and the fuel receiving taper pipe. By use of the device, a refueling process can be moretruly simulated so as to be favorable for better researching the quality of the refueling taper sleeve and the length and the rigidity of the refueling pipe, and especially researching the influence effect of different connection speeds for the refueling process.

Description

technical field [0001] The invention belongs to the technical field of low-speed wind tunnel drop test, and relates to a low-speed wind tunnel aerial refueling hose-taper sleeve dynamic characteristic test device. Background technique [0002] Air refueling technology is mostly based on soft refueling. Soft refueling technology is more suitable for flight formation refueling and UAV refueling due to its one-to-many refueling capability, high refueling safety, low cost, and flexible use. In the future, it will still be a very important way of refueling. However, due to the large influence of atmospheric turbulence in the soft refueling process, the influence of the refueling drogue by the atmospheric turbulence, and the head wave effect of the refueling machine, the success rate of one refueling is very low; in addition, the refueling pipe- The drogue produces complex dynamic characteristics, which has a major impact on the control of the oil receiver, and even the flight sa...
