 Such as Figure 1~5 , a synchronous aeroelastic-pressure measurement wind tunnel test device considering the effect of aerodynamic interference, including a test bench 2 fixed in the wind tunnel 1, and a test unit 3 arranged on the test bench 2, the test bench 2 is circumferentially Closed, with a number of concentric annular chute 21 on the top surface; the radial distance d between each chute 21 is equal to ensure that the auxiliary test unit can approach or move away from the main test unit in an equal adjustment manner relative to the main test unit unit, the opening width r of each chute 21 is equal to ensure the general installation of the auxiliary test unit; the test unit 3 is divided into two types, the main test unit and the auxiliary test unit, wherein the main test unit has one, which is arranged on all chutes 21 at the common center of the circle; there is at least one auxiliary test unit, which can be slidably arranged in the chute 21 and can be fixed by a...
 Such as Figure 6 , 7 , The difference with Embodiment 1 is that in this embodiment, it also includes sealing blocks 9 arranged in the thickness direction of the top surface of the test bench 2; the sealing blocks 9 are arranged in pairs in each chute, and the opposite sides are Round head type, the away side is connected to the inner side of the test bench in the thickness direction through the return spring 10 arranged horizontally; under no external force, the sealing blocks 9 in each chute will push against each other in pairs to seal the chute 21; when there is a vertical When the external force acts, the sealing block 9 overcomes the active force of the back-moving spring 10 and is pushed away; From the first embodiment, it is not difficult to find that there is a risk of wind blowing even if the opening width r of the chute 21 is small, so the structure of the sealing block 9 is designed and used in conjunction with the return spring 10, so that the auxiliary te...
