In one embodiment of the present disclosure, there is provided an aircraft that includes a cowling having a j-track mounted on the inwardly facing surface and a rod pivotally connected to a stationary part of the aircraft at a first end and moveable within the j-track at a second end, so that, when the cowling is opened, the second end moves to lock into the j-shaped portion and hold the cowling open. In various embodiments, the first end may be pivotally connected to the aircraft by a quick release pin, and the second end may be connected to the j-track by a torsion spring. In another embodiment of the present disclosure, the cowling is a bi-folding cowl having an upper portion and a lower portion, where the rod and the lower portion may include structures for retaining the lower portion in an opened position.

In one embodiment of the present disclosure, there is provided an aircraft having a bi-folding cowl for providing full access to equipment without completely removing the cowl. The bi-folding cowl has an upper portion and a lower portion mechanically connected along the adjacent edges, where the upper and lower portions fold so that the inner surfaces face each other when opened. In another embodiment, the bi-folding cowl has at least three maintenance positions, including partially-opened, fully-opened, and fully-opened, lying flat on the surface of the aircraft.

Gaskets, including aircraft gaskets, are disclosed, the gaskets having an elastomeric gel body and substantially incompressible skeletons. The bodies may be pliable and deformable and, in one example, may be comprised of a two-part chemically cured polyurethane that sets up as a gel after mixing with the web so that it is fully integral with the web and so that there is substantially no air bubbles or air pockets left in the web. The web may be a regular shaped web and made of nylon.

There is provided a method of mounting equipment to an aircraft having an empennage. The method comprises mounting equipment to a mounting structure for mounting to the aircraft; removing an access panel from the outer skin of the empennage of the aircraft to reveal an access panel opening into the empennage; and attaching the mounting structure to or within the access panel opening such that at least a portion of the equipment extends beyond the outer skin of the empennage. The shape of the mounting structure at least partly conforms to the shape of the access panel opening. The method also comprises covering the mounting structure and the equipment mounted thereon with a cover, and attaching the cover to the mounting structure or the empennage. An assembly, structure, tailplane and aircraft are also provided.

This disclosure relates to a support device for an actuator. The support device includes a support unit adapted to be mounted to a stationary structure, an attachment unit adapted to be attached to an actuator casing and a single pivot shaft, and the attachment unit is pivotably connected to the support unit via the single pivot shaft. The support device according to the present disclosure has a simple structure and is stable in operation. The present disclosure further relates to an air intake system for an auxiliary power unit, which includes the above support device for the actuator. In addition, the present disclosure further relates to an aircraft including the air intake system for the auxiliary power unit.

A cable release system configured to unlock a hold open rod mechanism or latch mechanism includes an actuator having a handle and a cable attachment. The cable release system also includes a cable connected at one end to the actuator and at another end to an unlocking mechanism associated with the hold open rod mechanism or the latch mechanism. The cable release system also includes the actuator being configured to move the cable and operate the unlocking mechanism associated with the hold open rod mechanism or the latch mechanism. The cable release system also includes the actuator and the handle being configured to be moved by personnel to move the cable and operate the unlocking mechanism associated with the hold open rod mechanism or the latch mechanism. The cable release system also includes the cable attachment including a lower slide and a release slide.

A housing includes a pressure relief door and a deflector. The pressure relief door includes a first door end disposed at a first hinge axis of the housing and an opposing second door end. The pressure relief door is rotatable between a first door position and a second door position about the first hinge axis and defines a portion of the housing in the first door position. The deflector includes a first deflector end disposed at a second hinge axis of the housing and an opposing second deflector end. The deflector is rotatable between a first deflector position and a second deflector position about the second hinge axis. Rotation of the pressure relief door from the first door position to the second door position effects rotation of the deflector from the first deflector position to the second deflector position.

This disclosure relates to an air inlet for an aircraft with an integrated hand hold. One innovative aspect of the subject matter described herein can be implemented as an air inlet on the exterior surface of a cowling for a rotorcraft, wherein the air inlet having a scoop that includes a bottom surface having a wide, flat, front edge that angles downward towards the back, an opening in the back for air to enter, and two lateral sides coupled to the bottom surface, where the two sides are planar on a top surface and become longer in height towards the opening in the back, and hand hold, where the hand hold is a trough or an indentation in the bottom surface of the scoop that extends along a side.

One example of a fairing for a rotorcraft includes an outer mold line portion (OML portion) and a bearing portion extending from the OML portion. The OML portion provides at least a portion of an outer mold line of the rotorcraft. Both the OML portion and the bearing portion shield a portion of a structural member. The bearing portion can protect the portion of the structural member from damage resulting from foot traffic associated with accessing an area nearby the structural member.
