Abstract
A improved tilt rotor aircraft comprising an airframe, at least one wing member coupled to the airframe, and at least one tilt rotor assembly carried by the at least one wing member. The improved tilt rotor aircraft includes a low-height tunable downstop assembly for isolating static and dynamic lateral loads between the tilt rotor assemblies and the wings. The low-height tunable downstop assembly comprises a pivotable striker assembly having an adjustable stiffness, and a cradle assembly adapted to releasably receive the striker assembly. The low-height tunable downstop assembly isolates yaw loads while providing a stiff vertical support.
