Convertible Aircrafts TRIZ Cases
- Ducted Fan Propulsion System for Aerial Vehicle Ground Travel
A ducted fan drive system integrates with a hubless wheel to enable aerial vehicle ground travel while protecting blades from obstacles.
- Dual Engine Multimodal Vehicle with Flexible Wing
A dual-engine vehicle combines a propeller and ground traction system with a flexible parafoil wing for versatile transport.
- Airlifting Device Nested Stacking Structure
A device for airlifting an object features a frame-like support structure with corresponding upper and lower end regions that engage in a form-fitting manner.
- Helicopter Rear Hatch Slides Sideways to Clear Loading Area
A helicopter rear hatch slides and rotates sideways to clear the loading area, resolving obstruction from conventional hinged doors during stretcher transport.
- Capture-and-Release Aircraft Vertical Takeoff
Rotor units lift fixed-wing aircraft vertically, reducing runway area requirements while preserving cruising speed and range.
- Amphibious Vehicle Takeoff Control via Coupled Dynamic Model
Segmenting suspension dynamics into a two-degree-of-freedom equation resolves motion state control precision challenges during amphibious vehicle touchdown.
- Clutch Arrangement for Roadable Aircraft Propulsion and Locking
A clutch arrangement uses a single axially slidable engagement member to transmit torque or lock the propeller shaft.
- Firefighting Drone with Detachable Landing Gear for Interior Access
A firefighting drone uses a detachable landing gear to transition from flight to ground movement inside buildings.
- Tandem Tiltrotor VTOL Aircraft Balance Control
Tandem tiltrotors counterbalance pitching moments during state transitions, resolving the trade-off between stability and flight duration in VTOL applications.
- Tiltrotor VTOL Aircraft Thruster Tilting Mechanism
Independent thrusters on transmission brace rods maintain a horizontal body during flight, eliminating driver discomfort from tilting fuselages.
