Foldable Drone Design Optimization Techniques

A propeller assembly for unmanned aerial vehicles that self-folds and unfolds without human intervention. The propeller blades have connectors that move within the central hub, allowing the blades to fold when at rest and extend when spinning during flight.

A modular, flat-packable drone kit can be assembled in multiple configurations with swappable components. The drone kit is made of flat plates that can be cut from a sheet of material, enabling low-cost manufacturing and compact packaging. The components can be secured using integrated mechanisms and elastic bands without specialized tools. The drone can be built in various configurations using different-sized propellers, above/below propeller placement, and modular accessories like cameras or grabbing arms. Multiple drones can be coupled, with one acting as a master flight controller.

Automatic folding and unfolding of multi-arm unmanned vehicles enable compact storage and long-distance deployment. When released, the arms of a UAV can automatically extend from a contracted position to an expanded position. This allows the UAV to be stored in a highly compact configuration for transport and then deployed by autonomously expanding the arms. The expansion can use actuation, shoulder/rotations, and release mechanisms to save over eight times the storage space.

Vertical take-off and landing unmanned aerial vehicle with a foldable fixed wing that improves stability and efficiency compared to existing designs. The VTOL drone has a twin-ducted fan power system, foldable wing, and retractable landing gear. The ducted fans provide vertical lift for takeoff/landing and horizontal thrust for forward flight. The ducts also stabilize the aircraft in crosswinds. The foldable wing reduces drag during vertical operations. The rearward center of gravity and duct position enable self-stabilization in the wind.

An unmanned flying device with foldable blades that collapse when not spinning. The blades extend and deploy due to centrifugal force when rotating. This provides a compact and durable drone construction that avoids damage on landing without needing landing gear. The collapsible blades automatically fold along the body when not spinning, protecting the blades and minimizing device size for transport.

A vertical take-off and landing unmanned helicopter with multiple rotors that can fold to a compact size for easy transportation. The helicopter has 4, 6, or 8 arms with a rotor. The arms pivot at one end to fold vertically along the fuselage. When folded, the rotors overlap, and the arms nest closely together to minimize the folded size. This allows the helicopter to reduce its size without needing longer, heavier arms or a larger fuselage.

A foldable drone design that protects itself and others during collisions. The drone arms have an impact protection mechanism that allows them to deform omnidirectionally when hitting something. This reduces peak forces and energy. The mechanism uses magnets, springs, or joints to keep the arms rigid until a maximum load is exceeded. The propellers have soft sections to reduce injury risk. This folding drone design prevents damage to the drone and injury to people during impacts.

Unmanned aerial vehicle (UAV) with foldable arms to improve portability and storage of drones. The UAV has multiple arms that can fold up towards the body when not in use, reducing its size for transportation. The arms extend outwards into a flight configuration when the UAV is operational.

A foldable drone with a lightweight folding structure to allow easy transport while maintaining flight performance. The drone has a central body with multiple arms that can rotate between extended positions for flight and folded positions for transport. The arms rotate about a common axis and lock in place in both positions using teeth and notches. This allows the drone to be easily folded into a compact transportation shape.

Collapsible unmanned aerial vehicle (UAV) that has foldable wings, tail, propellers, and control surfaces to reduce bulk and enable portable storage and launch from tubes or tubes. The UAV has a collapsible design with foldable wings, tail surfaces, and propellers that can be stored in compact form and extended when ready to fly. This allows the UAV to be packed in a small container for transport while enabling rapid deployment with fully functional flight surfaces. The foldable design allows the UAV to be man-portable, launched from tubes, and rapidly transition between compact storage and complete flight configurations.

A fully protected and foldable drone design to improve safety and portability while maintaining flight capability. The drone has a meshed protective housing around the rotors to prevent injuries. The rotors are mounted inside the housing. The drone also has foldable wings that can be folded up when not in use to reduce its size for easier transport.

Foldable arm design for unmanned aerial vehicles (UAVs) that allows compact storage and transport. The foldable arm has a joint that enables it to bend in two places, reducing its overall length when folded. This allows the UAV to be folded into a smaller package for easier carrying.

A foldable landing gear for unmanned aerial vehicles that can be fully retracted into the UAV body when folded. The landing gear uses a linkage mechanism and powered fold/unfold actuators to retract the legs. This allows the landing gear to be completely enclosed within the UAV body when not in use, reducing drag, improving aerodynamics, and preventing obstruction of the camera field of view. The landing gear linkage is designed to fold in a compact manner and the actuators are housed within the UAV body.

A foldable drone that can easily fold its arms inwards for compact storage and transport. The arms rotate relative to the body to fold upwards towards the fuselage. The rear arm folds first and fits below the fuselage, then the front arm folds and fits above the fuselage. The foldable propeller blades are positioned between the folded arms and the fuselage. This provides high space utilization after folding, compactness, clean appearance, and prevents exposed blades from contacting objects. The arm folding is enabled by a rotating mechanism with a pivot shaft connecting each arm to the fuselage.

Collapsible unmanned aerial vehicle (UAV) design that can be folded into a compact form for transport. The UAV has arms that can fold inwards towards the body, reducing its overall dimensions when not in use. This allows for easier packing and carrying of the UAV compared to fixed-arm designs. The folding arms are hinged segments that fold inward towards the body of the UAV.

Foldable drone that improves portability by allowing the wings to fold up against the body. The drone has a body and two wings. The wings are connected to the body with hinges so they can fold up. When folded, the drone becomes more compact and easier to carry. When unfolded, the wings provide lift for flight.

Compact unmanned flying device with collapsible rotor blades that automatically fold when not spinning or spinning slowly to protect the blades and make the device easier to transport. The blades deploy and extend when spinning due to centrifugal force. The unmanned flying device has a body, foldable blades, and a collapsing mechanism to fold the blades against the body when not spinning.
