Description

Valve Test Module and Gravity Servile Test Apparatus

The present invention relates to the performance test of the gravity tracking valve, in particular, the acceleration tracking performance of the valve is tested by providing instantaneous acceleration direction change while applying gravity acceleration on the ground, so that a reliable performance test can be performed without the actual flight test. The gravity tracking test apparatus is applied to the valve test module.

In general, guided weapons and aerospace systems frequently change attitude and acceleration due to the maneuverability in the air, and thus the valve applied to the guided weapon or aerospace system must always ensure smooth and stable operation performance regardless of acceleration direction and strength.

Therefore, valves applied to guided weapons or aerospace systems, regardless of their type, must be tested for performance under specific acceleration conditions.

Valve test methods for this purpose are variously applied, but there are representative methods using centrifugal force and centripetal force and linear acceleration.

For example, the centrifugal force and centripetal force may be used as a centrifugal acceleration test apparatus.

The centrifugal acceleration test apparatus can be equipped with a test object (valve) and consists of a long arm whose center of rotation is to generate centrifugal force and centripetal force, and by changing the rotational speed of the center of rotation when the long arm rotates By accelerating, the acceleration applied to the test object (valve) can be varied to varying magnitudes.

On the other hand, the way in which linear acceleration is used may be a rail accelerator.

The rail accelerometer is provided with a rail of a certain length and a test object (valve) to move on the rail with an instantaneous acceleration to apply acceleration to the test object (valve), and adjust the magnitude of the instantaneous acceleration to the test object (valve). The applied acceleration can be varied in various magnitudes.
