The environmental effects of the sand and dust test chamber are as follows:
The dust environment is an important environmental factor that causes the failure of many military weapons and equipment, including helicopters. The widely distributed sand and dust environment has a serious impact on military equipment and helicopter components, systems and airborne equipment. The main damage types are: erosion, wear, corrosion and penetration. For helicopters, the sand and dust carried by strong winds deliberately wear the moving parts and fixed surfaces of the aircraft under the action of natural wind and rotor-induced wash air flow. Angled particles can penetrate gaps, cracks, bearings, seals and The connection of electrical appliances causes damage to the equipment.
The natural sand and dust environment is usually related to dry and hot areas, but this environment also exists seasonally in most other areas. Therefore, the sand and dust storms generated in nature are an important factor to be considered when using equipment. But as the degree of mechanization of military operations increases, they cause more problems than natural sand and dust environments. In order to determine whether the sand and dust test box is suitable for the equipment to be tested.
