Abstract: A mounting arrangement for mounting a rotary engine to an aircraft structure, wherein the engine has a three orthogonal axes comprising: a roll axis; a pitch axis; and a yaw axis. The mounting arrangement comprises: one-degree-of-freedom links with reaction axes passing through the roll axis. A separate roll constraint has a moment reaction about the roll axis to decouple the torque roll mode from the other one-degree-of-freedom links.

Abstract: A damping device for connecting a bearing housing to a bearing outer race is provided. The damping device may permit an allowable range of radial movement of the bearing. The damping device has an elastomeric body connected to one of the bearing outer race and the bearing housing and a cover portion connected to the other one of the bearing outer race and the bearing housing. It also has two or more deformable fluid chambers fluidly connected to one another via at least one orifice and in which fluid is encapsulated. The damping device may dissipate at least partially vibrations travelling between the bearing housing and the bearing outer race by compressing its elastomeric body and by discharging fluid from one fluid chamber to another. There may be a plurality of such damping devices disposed circumferentially about the bearing outer race.

Abstract: A connector for multi-phase conductors. The connector includes conductors for conducting multi-phase currents, and at least one conductive plate corresponding to each phase. Each conductive plate defines apertures for the conductors to pass through, there being at least one aperture in each conductive plate for each respective conductor. Each conductive plate includes at least one connecting member for forming an external electrical connection. Each conductor passes through a respective aperture of each conductive plate. Each conductor is selectively coupled to form electrical connection only to a conductive plate corresponding to the respective phase of the conductor.
