A rotary wing aircraft comprising an upper primary skin that separates an aircraft interior region from an aircraft upper deck. The aircraft upper deck comprises engine compartments, a tail rotor drive shaft arranged therebetween, a firewall arrangement, and a central bracket that is rigidly attached to the upper primary skin below the tail rotor drive shaft 12 c . The central bracket provides central bracket lugs in the engine compartments above the firewall. The engine compartments comprise inboard fixations with inner main mounting brackets adapted for being rigidly attached to engines and to inboard lateral mounts that attach the inner main mounting bracket with the central bracket lugs.

A rotorcraft with at least one main rotor and a fuselage, comprising: a tail boom connected to the fuselage, the tail boom extending in a longitudinal direction from the fuselage toward a duct-type portion; a shroud provided at the duct-type portion and forming a transverse duct comprising an air inlet region and an air outlet region; the transverse duct having a longitudinal extension; at least one ducted tail rotor rotatably arranged in the transverse duct; and an integral stabilizer arrangement mounted to the shroud, the integral stabilizer arrangement being embodied in box configuration and arranged laterally on a side of the shroud on which the air inlet region of the transverse duct is arranged.

A rotary-wing aircraft with a fuselage that comprises a load carrying shell structure and a load carrying stiffening member structure, wherein the load carrying shell structure delimits an aircraft inner volume, and wherein the load carrying stiffening member structure is arranged outside of the aircraft inner volume on an outer surface of the load carrying shell structure.

A rotorcraft with at least one main rotor and a fuselage, comprising: a tail boom connected to the fuselage, the tail boom extending in a longitudinal direction from the fuselage toward a duct-type portion; a shroud provided at the duct-type portion and forming a transverse duct comprising a circumferential direction and a longitudinal extension oriented at least essentially perpendicular to the circumferential direction and the longitudinal direction of the tail boom; and at least one ducted tail rotor rotatably arranged in the transverse duct; wherein the shroud comprises a first section connected to the tail boom and a second section spaced apart from the tail boom and diametrically opposed to the first section, the first section comprising an airfoil-like aerodynamic profile.

An air directing arrangement for controlling flow of air at a compartment outlet of a fuselage of a rotorcraft. The air directing arrangement comprises a continuous surface that covers the compartment outlet outside the fuselage and forms a flow channel for directing an air flow at the compartment outlet; a first flow-through opening that is formed at a first position of the flow channel, wherein the first flow-through opening forms an air inlet area; and a second flow-through opening that is formed at a second position of the flow channel, wherein the second flow-through opening is arranged downstream of the first flow-through opening in the predetermined flow direction, and wherein the second flow-through opening forms an air outlet area; wherein the air inlet area is smaller than the air outlet area.

A structural panel for use in aeronautical applications. The structural panel includes a composite skin that comprises composite material and a stiffening framework that is rigidly attached to the composite skin. The composite skin is configured as a load bearing monolithic structure with a structure thickness of less than 1 mm. The composite skin comprises a composite laminate with a plurality of carbon composite plies. Each one of the plurality of carbon composite plies comprises a ply thickness in a range from 0.02 mm to 0.05 mm.

A modular load carrying apparatus for a rotary wing aircraft and to a method of operating a modular load carrying apparatus. The modular load carrying apparatus may include a tube, first and second caps that are located inside the tube at first and second axial ends, and at least first and second removable platforms that are interchangeably installable on the tube. The second cap comprises a protrusion that protrudes from the axial end, and each one of the at least first and second removable platforms is adapted for being slidable over the first axial end of the tube and restrained by the second cap at the second axial end of the tube.

A rotary-wing aircraft, comprising: an airframe with an airframe skin that forms an outer airframe loft line and encloses an airframe inner volume, wherein the airframe skin comprises at least one airframe opening; and at least one attachment interface that is mounted to the airframe skin at the airframe opening and configured for a releasable attachment of an external device, wherein the at least one attachment interface comprises an interface cap with a mounting flange that is rigidly attached to the airframe skin, wherein the interface cap comprises at least one pocket that forms a pocket base; and a ball stud with a stud shaft and a ball, wherein the ball stud is rigidly attached to the pocket base and extends at least partly into the airframe opening.

An aircraft door including a door leaf, a door frame, a support arm assembly, and first and second connecting elements. The first connecting element connects the support arm assembly with the door leaf and includes a first adjustment unit that is adapted for adjusting the position of the door leaf relative to the door frame along a first axis (x-axis). The second connecting element connects the support arm assembly with the door frame and includes a second adjustment unit that is adapted for adjusting the position of the door leaf relative to the door frame along a second axis (z-axis) that is perpendicular to the first axis (x-axis).

A seat beam for a rotary-wing aircraft adapted for receiving seat posts of a seat bench device, including a first seat beam end; a second seat beam end; and a seat beam body connecting both. A link with a link working line is arranged at the first seat beam end and includes: a link-beam fixation that is attached to the seat beam body and rotatable around a first link rotational axis that is perpendicular to the seat beam extension axis, and a first seat beam fixation that is connected to the link-beam fixation and adapted for being attached to the airframe attachment point such that the first seat beam fixation is rotatable around a second link rotational axis that is parallel to the first link rotational axis.
