Flexible mounting assembly for an air frame structure

摘要

A flexible mounting assembly allows relative movement between a top and a bottom structural member of an air frame, for instance, a helicopter. The flexible mounting assembly comprises a vertical frame member and an isolation frame member where one of the vertical frame member and the isolation frame member has a pin and the other of the vertical frame member and the frame isolation member has an aperture adapted to slidingly receive the pin in a way to accommodate relative vertical motion therebetween while substantially restraining lateral movement therebetween. The flexible mounting assembly may also include a horizontal shear wall assembly extending between adjacent vertical frame members that accommodates relative vertical motion between top and bottom structural members while substantially restraining lateral movement therebetween.
