Abstract

The invention relates to the field of wind tunnel tests, and discloses an improved wind tunnel inlet test model support system. The model support system includes a ventilation arm and an angle of attack pre-bias rod. The ventilation arm is connected to the wind tunnel angle of attack mechanism. The roll angle shaft mechanism is connected; the ventilation arm is provided with a gas passage, a routing passage, and a ventilation cavity in sequence from the inside to the outside; the gas passage and the ventilation cavity are coaxially arranged; the ventilation arm and the angle of attack pre-biased rod connection; the angle of attack pre-bias rod is provided with an extended section of the gas passage connected with the gas passage, and an extended section of the routing passage connected with the routing passage; the ventilation cavity is communicated with the ventilation pipeline, and the extended section of the gas passage is connected with the The air outlet pipeline is connected; the wall of the angle-of-attack pre-deflection rod has a wiring hole. The invention solves the problem that the traditional model support system in the prior art cannot realize the integrated setting of ventilation and routing, and the problem of inconvenient operation caused by many instruments and many pipelines in the wind tunnel test process.

Description

technical field [0001] The invention belongs to the field of wind tunnel tests, and more particularly relates to an improved wind tunnel inlet test model support system. Background technique [0002] The air intake is one of the important parts of the air-breathing aircraft power plant. In order to study and evaluate the aerodynamic performance of the aircraft inlet in the wind tunnel test, it is usually necessary to simulate the flow conditions of the aircraft inlet pipe in the wind tunnel, and measure the angle of attack and sideslip angle of the inlet at different incoming flow Mach numbers aerodynamic performance. [0003] Typically, the intake duct model is mounted in a wind tunnel by a support system. Due to the relatively low airflow velocity, small aerodynamic load, and large size of the wind tunnel, the low-speed wind tunnel generally does not have high requirements for the support system. Fixing and protection are relatively easy, and simple fixation and protect...
