Certain aspects of the present disclosure provide a vehicle, comprising: a housing; a battery comprising a plurality of layers and disposed within the housing; and a first removable battery compression device disposed within the housing and configured to apply compressive force to the plurality of layers of the battery via a first side of the battery.

A manned/unmanned aerial vehicle adapted for vertical takeoff and landing using the same set of engines for takeoff and landing as well as for forward flight. An aerial vehicle which is adapted to takeoff with the wings in a vertical as opposed to horizontal flight attitude which takes off in this vertical attitude and then transitions to a horizontal flight path. A tailless airplane which uses a control system that takes inputs for a traditional tailed airplane and translates those inputs to provide control utilizing non-traditional control methods.

The embodiment is an unmanned aerial vehicle. The unmanned aerial vehicle includes: an airframe, including first mounting portions, where the first mounting portion includes a first mounting body and connecting rods formed on the first mounting body, the connecting rods extending in a pitch axis direction; and a power assembly, including a first assembling body and eccentric wheels mounted on the first assembling body, where the eccentric wheel is rotatable between a first rotation position and a second rotation position of the first assembling body around a rotation axis of the first assembling body, the rotation axis being perpendicular to the pitch axis direction.

The embodiments is an unmanned aerial vehicle. The unmanned aerial vehicle includes: an airframe; and a fixed-wing assembly and a rotor assembly, both replaceably connected to the airframe. The fixed-wing assembly is connected to the airframe to form a vertical take-off and landing fixed-wing unmanned aerial vehicle and the rotor assembly is connected to the airframe to form a multi-rotor unmanned aerial vehicle, thereby implementing an unmanned aerial vehicle that can switch between the vertical take-off and landing fixed-wing unmanned aerial vehicle and the multi-rotor unmanned aerial vehicle.

An aircraft includes an airframe with first and second wings having a fuselage extending therebetween. A propulsion assembly is coupled to the fuselage and includes a counter-rotating coaxial rotor system that is tiltable relative to the fuselage to generate a thrust vector. First and second yaw vanes extend aftwardly from the fuselage. A flight control system is configured to direct the thrust vector of the coaxial rotor system and control movements of the yaw vanes. In a VTOL orientation of the aircraft, differential operation of the yaw vanes and/or differential operations of first and second rotor assemblies of the coaxial rotor system provide yaw authority for the aircraft. In a biplane orientation of the aircraft, collective operation of the yaw vanes provides yaw authority for the aircraft.

Systems, devices, and methods for a ground support system for an unmanned aerial vehicle (UAV) including: at least one handling fixture, where each handling fixture is configured to support at least one wing panel of the UAV; and at least one dolly, where each dolly is configured to receive at least one landing pod of the UAV, and where each landing pod supports at least one wing panel of the UAV; where the at least one handling fixture and the at least one dolly are configured to move and rotate two or more wing panels to align the two or more wing panels with each other for assembly of the UAV; and where the at least one dolly further allows for transportation of the UAV over uneven terrain.

An aircraft operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft has an airframe including first and second wings with first and second pylons coupled therebetween. A distributed thrust array is coupled to the airframe including a plurality of propulsion assemblies coupled to the first wing and a plurality of propulsion assemblies coupled to the second wing. A cargo pod is coupled between the first and second pylons. The cargo pod is rotatable between a loading configuration, substantially perpendicular to the wings and a transportation and deployment configuration, substantially parallel to the wings. A flight control system is configured to independently control each of the propulsion assemblies and to autonomously deploy a payload from the cargo pod at a desired location.

The present application provides an unmanned aerial vehicle (UAV) for a long duration flight. An exemplary UAV may include a UAV body assembly. The UAV may also include a flight control system (FCS) coupled to the UAV body assembly. The UAV may further include a motor coupled to the UAV body assembly at one end and coupled to a propeller at the other end. The FCS is communicatively connected to the motor. A center of gravity (CG) of the UAV is at a point between 21% and 25% of a mean aerodynamic chord (MAC) of the UAV.
