Abstract

The invention relates to the field of wind tunnel tests, and discloses an improved wind tunnel air inlet test model supporting system which comprises a ventilation arm and an attack angle pre-deviation rod, and the ventilation arm is connected with a roll angle rotating shaft mechanism on a wind tunnel attack angle mechanism; the ventilation arm is sequentially provided with a gas passage, a wiring passage and a ventilation cavity from inside to outside; the gas passage and the ventilation cavity are coaxially arranged; the ventilation arm is connected with the attack angle pre-deviation rod; a gas passage extension section communicated with the gas passage and a routing passage extension section communicated with the routing passage are arranged in the angle-of-attack pre-deviation rod; the ventilation cavity is communicated with the ventilation pipeline, and the gas passage extension section is communicated with the gas outlet pipeline; and a wiring hole is formed in the wall of the attack angle pre-deviation rod. The problems that in the prior art, a traditional model supporting system cannot achieve integrated arrangement of ventilation and wiring, and operation is inconvenient due to the fact that instruments and pipelines are many in the wind tunnel testing process are solved.

Description

technical field [0001] The invention belongs to the field of wind tunnel testing, and more particularly relates to an improved model support system for a wind tunnel intake duct test. Background technique [0002] The air intake is one of the important parts of the power plant of the air-breathing aircraft. In order to study and evaluate the aerodynamic performance of the aircraft intake port in the wind tunnel test, it is usually necessary to simulate the flow conditions of the aircraft intake port in the wind tunnel, and measure the angle of attack and sideslip angle of the intake port under different incoming Mach numbers. Aerodynamic performance. [0003] Typically, the intake duct model is mounted in the wind tunnel by a support system. In low-speed wind tunnels, due to the relatively low airflow velocity, small aerodynamic load and large size of the wind tunnel, the test requirements for the support system are generally not high. It is relatively easy to fix and pro...
