Embodiment 1

[0024] The embodiment of the present invention is provided with aircraft model 1, rod type six-component force balance 6, front taper sleeve 7, rear taper sleeve 14, sleeve 12 and pole 5, and aircraft model 1 is pulled and suspended by traction rope 2, and traction rope 2 One end is connected to winch motor assembly 4 by pulley 3, and the other end of traction rope 2 is connected with strut 5, is used for suspending and supporting aircraft model 1, and rod type six-component force balance 6 is located in aircraft model 1, and rod type six The force component balance 6 is coaxial with the aircraft model 1, the front end of the rod-type six-component force balance 6 is connected with the front cone sleeve 7 through 8, and the rear end of the rod-type six-component force balance 6 is connected with the rear cone sleeve 14 through a bolt 15, and the sleeve The cylinder 12 is fixedly connected to the rear taper sleeve 14 through bolts 17, the sleeve 12 is installed parallel to the r...

Embodiment 2

[0032] Figure 4 It is a schematic diagram of Embodiment 2 of the present invention. The installation and fixing methods of the airplane model and the rod-type six-component force balance assembly are the same as in Embodiment 1. to combine Figure 5 Example cross-sectional view with Figure 6 It can be seen that the difference between embodiment 2 and embodiment 1 is that there is no tail plug, and the rear taper sleeve 14 located at the rear end of the balance is extended with an extended hollow pipe 19 extending out of the tail. Some small poles 5 are arranged on the prolongation hollow pipe 19, are used for tying the traction rope.

[0033] Embodiment 2 is an extension of the application of Embodiment 1. Different embodiments can be adopted according to the aerodynamic layout of the model appearance and the test purpose requirements, or the plug 16 of embodiment 1, or the extended hollow tube 19 added in embodiment 2, to change the layout of the rope system, thereby ch...

Abstract

The invention relates to air vehicle models, in particular to a model rope supporting system capable of realizing wind tunnel virtual flight. The model rope supporting system is provided with an airplane model, a rod type six-component balance, a front taper sleeve, a rear taper sleeve, a sleeve and a supporting rod. The airplane model is pulled and hung by a pulling rope, one end of the pulling rope is connected to a winch motor assembly through a pulley, and the other end of the pulling rope is connected with the connecting rod and used for hanging and supporting the airplane model; the rod type six-component balance is coaxially arranged in the airplane model, the front end of the rod type six-component balance is connected with the front taper sleeve through bolts, and the rear end of the rod type six-component balance is connected with the rear taper sleeve through bolts; the sleeve is fixedly connected to the rear taper sleeve through bolts and installed parallel to the rod type six-component balance without making contact with the surface of the rod type six-component balance; the airplane model is locked to the front taper sleeve through bolts, the supporting rod is arranged on the sleeve and used for tying the pulling rope, and the pulling rope is connected with a pulley arranged on an external base. The model rope supporting system is easy and convenient to install and high in generality, the influence on a flow field is small, and testing is convenient.

Description

technical field [0001] The invention relates to an aircraft model, in particular to a model rope support system capable of realizing virtual flight in a wind tunnel with a built-in six-component force balance. Background technique [0002] Wind tunnel test is one of the most important means to predict the aerodynamic performance of aircraft and obtain the key aerodynamic parameters required for aircraft design. Wind tunnel test is also one of the main means of aerodynamic basic research and applied research, so it plays an extremely important role. [0003] In the wind tunnel test, the required various aerodynamic load data are generally obtained through a six-component force balance. Among them, the rod-type six-component force balance is widely used in the measurement of aerodynamic parameters because of its simple structure and high measurement accuracy. The traditional method is to install the rod-type six-component force balance in series on the support rod, and then ...
