An apparatus for supporting a wing flap of an aircraft includes a support fitting configured to be coupled to a wing of the aircraft. The apparatus also includes a first link, pivotably coupled to the support fitting and configured to be pivotably coupled to the wing flap, and a second link, separably coupled to the support fitting and configured to be pivotably coupled to the wing flap.

A wing system (2) for an aircraft includes a movable flow body (6) and a cover panel (8), wherein the flow body (6) and the cover panel (8) both are movably supported on a main wing body (4). While the flow body (6) is actively driven into upwards or downwards deflected positions, the cover panel (8) is coupled with the flow body (6) to follow its motion. The cover panel covers a part of the flow body (6) and the main wing body (4) in order to provide a substantially continuous, closed outer contour.

A free-streamline airfoil includes a front portion, the front portion including a leading edge geometry configured to force a sudden separation of the flow, and a contoured rear portion.

A public transportation system combines a unique combination of components that includes interoperable electric-powered vehicles, facilities, hardware and software having specifications, standards, processes, capabilities, nomenclature, and concepts of operations that together include a concerted, comprehensive, multi-modal, future system for moving people and goods that is herein named Quiet Urban Air Delivery (QUAD) and in which uniquely-capable, ultra-quiet, one to six-seat, electrically-powered, autonomous aircraft (SkyQarts) fly sub-193 kilometer trips on precise trajectories with negligible control latency and perform extremely short take-offs and landings (ESTOL) with curved traffic patterns at a highly-distributed network of very small, airports (“SkyNests”) that themselves have standardized compatible facilities that interoperate with SkyQarts as well as with versatile, autonomous electric-powered payload carts (EPCs) and robotic delivery carts (RDCs) to provide safe, fast, on-demand, community-acceptable, environmentally friendly, high-capacity, affordable door-to-door delivery of both passengers and cargo across urban, suburban and rural settings across the globe.

Example implementations relate to simple to manufacture flap assemblies with failsafe jam-resistant flap tracks. An example flap assembly may include a track having an elongate structure and a flap carriage configured to move along a length of the track. The track is configured to couple to an aircraft wing and the flap carriage includes a primary roller and a pair of secondary rollers configured to secure the flap carriage to the track. A top portion of the flap carriage is configured to couple to a flap such that movement of the flap carriage along the length of the track enables movement of the flap relative to the aircraft wing.

A rotor blade assembly includes a rotor blade having inboard and outboard regions, a blade body, and an internal spar, the blade body defining leading and trailing edges. A trailing edge assembly extends from and is connected to the trailing edge, and has a trailing edge flap and an actuator configured to deploy the trailing edge flap between first and second positions. In one of the first and second positions, an upper surface of the trailing edge flap conforms in profile to an upper surface of the rotor blade, and in the other, the trailing edge flap is inclined relative to the blade. During hovering flight, at least one trailing edge flap segment is deflected to enhance hover performance. During forward flight, at least one trailing edge flap segment is either not deflected for reduced effect on forward flight or is deflected for additional thrust.
