Abstract

The embodiment of the application provides a wind tunnel test model supporting device and system. A first pulley and a second pulley, which the wind tunnel test model supporting device comprises, arearranged at one end of an airplane model, and a third pulley and a fourth pulley are arranged at the other end of the airplane model; one end of a first rope is connected with a first wall plate included in a wind tunnel test cavity, the other end of the first rope passes through the first pulley and the second pulley to be connected with a second wall plate which is included in the wind tunnel test cavity and is opposite to the first wall plate; and one end of a second rope is connected with a first pitching mechanism, the other end of the second rope passes through the third pulley and the fourth pulley to be connected with a second pitching mechanism, and the first pitching mechanism and the second pitching mechanism are used for controlling the airplane model to take the rotation motion around a first direction determined by two ends of wings of the airplane model, so that when the airplane model has a certain freedom degree, an attitude of the airplane model can be regulated in the wind tunnel test process.

Description

Technical field [0001] This application relates to the technical field of wind tunnel testing, and in particular to a wind tunnel testing model support device and system. Background technique [0002] During part of the test on the wind tunnel test model (aircraft model), the wind tunnel test model needs to be fixed in the wind tunnel test cavity, and the fixing device must be a soft support structure in order to imitate a real flight scenario. However, the existing soft support structure cannot provide real rigid body degrees of freedom for the wind tunnel test model, and during the test process, it is necessary to design a special steering gear device on the wind tunnel test model to control the attitude of the wind tunnel test model. Making adjustments is very complicated. [0003] In view of this, how to provide a test mechanism that can meet the freedom and attitude adjustment requirements of the wind tunnel test model is a problem for those skilled in the art. Summary of th...
