Noise screening aircraft hangar - has movable wall for sloping triangular opening formed by triangular panel walls

摘要

The movable wall is provided at one end of a hanger used for testing aircraft on the ground without disseminating noise. Fixed walls consist of two triangular panels (1), enclosing a virtually triangular area, and a limited triangular opening, encompassed by the movable wall (2), and inclined from the vertical. The triangular panels may be inclined towards each other, and can form the whole, or almost the whole, of the fixed walls. The movable one can be a flat panel, pref. swivelling about a horizontal axis at the end opposite to the base side. This is versatile, easily assembled from prefabricated components and lightweight but stable.
