A drone-type air mobility vehicle includes a body, a plurality of rotors, and a plurality of rotor arms configured to connect the plurality of rotors to the body. The drone-type air mobility vehicle further includes: a plurality of air flaps provided in the rotor arms, respectively, and configured to be deployed downwards with the respect to the respective rotor arms by gas injected into the air flaps; and a controller configured to determine whether the rotors are abnormal, based on a yaw rate of the mobility vehicle and state information of the rotors, and the controller configured to determine whether to deploy the air flaps according to a result of the determination on whether the rotors are abnormal.

Systems, devices, and methods for an extruded wing protection and control surface comprising: a channel proximate a leading edge of the control surface, a knuckle disposed about the channel, a leading void, a trailing void, and a separator dividing the leading void and the trailing void; and a plurality of notches disposed in the extruded control surface proximate the leading edge of the control surface.

A slat arrangement for a wing of an aircraft. The arrangement has a movable leading-edge slat and a connection section. The leading-edge slat includes a slat leading edge and a slat trailing edge. The connection section includes a receiving opening for receiving the slat trailing edge. The connection section includes an overhang having a free end. The slat trailing edge is configured to be translated under the overhang. A trailing region of the slat is configured to be elastically deformed by the overhang when the slat trailing edge is moved into the receiving opening.

Truncated flap support fairings with active flow control system for aircraft and related methods are disclosed herein. An example aircraft includes a wing having a fixed wing portion, a flap moveably coupled to the fixed wing portion, a flap support fairing coupled to a bottom of the flap, the flap support fairing having an aft end, and an active flow control system including a nozzle. The nozzle is to eject high velocity air in a streamwise direction from the aft end of the flap support fairing.

Methods and systems relating to the design and testing of systems that include hinged flight control surfaces of aircraft are disclosed. The systems and methods disclosed herein make use of a structural model representing a structural environment of the system in a relatively simple manner. In various embodiments, the structural model comprises one or more actuation branches having a common linear actuation direction, a load mass, and a massless connector representative of a hinge line of the flight control surface. The massless connector is connected to and disposed between the one or more actuation branches and the load mass and is movable along the common linear actuation direction so that linear movement of the massless connector is correlated to rotational movement of the hinged flight control surface.
