Strapped windshield assembly for rotorcraft

摘要

This description relates to a strapped windshield assembly for a rotorcraft (200,300). In some implementations, the rotorcraft (200, 300) includes an airframe (202, 302, 502), a windshield (204, 504), and a plurality of independent straps (210, 510) connected to the airframe (202, 302, 502) and the windshield (204, 504), the straps (210, 510) operative to move independently with respect to one another. The independent movement of the straps (210, 510) allow relative movement of portions of the windshield (204, 504) in response to a strike. In some implementations, the straps (210, 510) are spaced every 4-6 inches along an edge of the windshield (204, 504). In some implementations, the straps (210, 510) are over an edge of the windshield (204, 504). The straps (210, 510) can have a modulus of elasticity of 8-12 millions of pounds per square inch (MSI). The windshield (204, 504) can include polycarbonate material.
