<p>A canopy assembly for an aircraft includes a forward canopy panel (2) and a rear canopy panel (4) carried by a support frame. The canopy panels (2 and 4) are mounted on the support frame (6) by buttstraps (40,42,44). The bottom edges of the forward canopy panel (2) and the rear canopy panel (4) are set in a bed of sealing compound. A bed of a release agent prevents adhesion between the front part of the forward canopy panel (2) and the bed. The canopy panels (2 and 4) are attached to one another at a central region by internal and external buttstraps (56 and 58). The adjacent parts of the panels (2 and 4) are contained in beds of sealing compound, and a release agent is applied to said adjacent parts. The rear edge of the canopy panel (2) and the front edge of the canopy panel (4) are scalloped adjacent each clamping bolt. In the event of a birdstrike the forward canopy panel (2) deforms and moves locally rearwardly with respect to the aircraft fuselage. The central buttstraps may also move locally rearwardly with respect to the aircraft fuselage and rear panel (4).</p> |
