An aerial vehicle may include a fuselage; and one or more propellers coupled to the fuselage, wherein the aerial vehicle may have at least a taking off or landing state and a cruise state. In response to the aerial vehicle being in the taking off or landing state, an angle between a longitudinal axis of the fuselage and a horizontal plane may be within a first angular range and in response to the aerial vehicle being in the cruise state, an angle between the longitudinal axis of the fuselage and the horizontal plane may be within a second angular range. A maximum value of the second angular range may be less than a minimum value of the first angular range. In response to the aerial vehicle switching between the takeoff or landing state and the cruise state, the fuselage and the propellers may tilt as a whole.

A method of deploying an unmanned aerial vehicle (UAV) includes launching a UAV and deploying at least one portion of a wing assembly from a stowed configuration to a deployed configuration in which the at least one portion of the wing assembly extends away from a body of the UAV. Deploying the portion of the wing assembly, which may be an outboard portion of a wing assembly, includes deflecting an aerodynamic control surface on the at least one portion of the wing assembly to cause an aerodynamic force to move the portion of the wing assembly into the deployed configuration without assistance from a spring or motor. An unmanned aerial vehicle (UAV) includes a UAV having a body and a plurality of wing assemblies carried by the body, at least a portion of a wing assembly is deployable using aerodynamic forces and without assistance form a spring or motor.

A deployable device mountable on a carrier vehicle and configured to collect situation awareness data. The deployable device includes at least one recorder device configured to collect situation awareness data. The deployable device is capable of being ejected from the carrier vehicle and can be configured to operate as a vehicle and/or be towed by the carrier vehicle. The deployable device can continue collection of situation awareness data after being ejected.

An air-charging unmanned aerial vehicle set is provided, including a charging unmanned aerial vehicle and a functional unmanned aerial vehicle. The charging unmanned aerial vehicle includes a first unmanned aerial vehicle body, a plurality of first propeller units, a rotation stage, a first battery slot and a second battery slot. The first propeller units are disposed on the first unmanned aerial vehicle body. The rotation stage is disposed on the first unmanned aerial vehicle body. The first battery slot and the second battery slot are disposed on the rotation stage. The functional unmanned aerial vehicle includes a second unmanned aerial vehicle body, a plurality of second propeller units, a third battery slot and a battery cover. The second propeller units, the third battery slot and the battery cover are disposed on the second unmanned aerial vehicle body.

An apparatus, having: a fuselage body section (180) configured to be secured to an aircraft fuselage (16); a pivot column (310) protruding from the fuselage body section; and a center wing section (214) configured to be secured to a center wing panel of a trifold wing (200). The fuselage body section and the center wing section are configured to cooperate with each other to rotate the center wing section relative to the fuselage body section from a stowed position (250) to a deployed position (302). The pivot column comprises a column feature (240) configured to engage with tip features (236) of the trifold wing to hold the trifold wing in a folded configuration when the trifold wing is in the stowed position and to disengage from the tip features as the trifold wing rotates to the deployed position, thereby freeing the trifold wing to unfold.

An adaptive aerial vehicle includes a vehicle support, at least one frame assembly mounted relative to the support, at least one propulsion unit mounted to the frame assembly and operable to move the adaptive aerial vehicle, and an actuator configured to move the support relative to the frame assembly to redistribute the weight of the adaptive aerial vehicle.

A cam-locking system for use with a retractable driveshaft that includes a housing, a cam carrier located at least partially the housing, and a cam rotatably coupled to the cam carrier. Translation of the cam carrier along a central axis allows the cam to rotate into cooperative engagement with a catch recess on an interior surface of the housing, preventing the cam carrier from translating backwards, and thereby maintaining the retractable driveshaft in an engaged position. Further advancement of the cam carrier allows that cam to rotate into and unlocking gap in the interior surface of the housing, which enables the cam carrier to translate backwards along the central axis below the locked position, thereby disengaging the retractable driveshaft.

Systems and methods include providing an aircraft with a fuselage and a wing assembly rotatable relative to the fuselage about a stow axis between a flight position and a stowed position. The aircraft includes an engine reduction gearbox having a retractable driveshaft that selectively engages the mid-wing gearbox via axially translatable motion along a rotation axis when the wing assembly is in the flight position. The mid-wing gearbox includes a plunger seal that is displaced in response to contact with the retractable driveshaft. Displacement of the plunger seal allows lubricant to flow through an inner bore in the retractable driveshaft, across splines of the retractable driveshaft and the mid-wing gearbox, and through lubrication ports in the mid-wing gearbox to lubricate the engine reduction gearbox, splines of the retractable driveshaft and the mid-wing gearbox, and the mid-wing gearbox via a single lubrication system.

An unmanned aerial vehicle arm adjustment device for adjusting an unmanned aerial vehicle arm into a folding state or an extracting state with respect to a fuselage of the aerial vehicle includes: left and right curb plates connected to the fuselage; a rocking arm connected to the unmanned aerial vehicle arm, wherein one end of the rocking arm is articulated with the left and right curb plates, and a first engaging part is provided on the rocking arm; and a locking member articulated with the left and right curb plates, wherein the locking member is provided with a second engaging part for engaging with the first engaging part; wherein the locking member is adapted to rotate in a first direction to force the second engaging part to engage with the first engaging part so as to hold the rocking arm such that the unmanned aerial vehicle arm is in the extracting state; and wherein the locking member is adapted to rotate in a second direction opposite to the first direction to force the second engaging part to disengage with the first engaging part so as to release the rocking arm such that the unmanned aerial vehicle arm is able to be rotated into the folding state.
