Aircraft Control TRIZ Cases
- Retractable Delivery Shroud for UAV Noise Reduction
A retractable delivery shroud channels payload descent and reflects acoustic waves from an aerial vehicle.
- Vertical Trajectory Profile Optimization for Flight Cost Minimization
Optimizes flight costs by computing vertical trajectories with precise altitude changes, resolving inefficiencies from unrelated geographic waypoints.
- Elastically Deformable Aircraft Track Container
A corrugated track container uses elastic deformation to accommodate ice, eliminating heavy drainage systems and reducing aircraft weight.
- Aircraft Flap System with Recessed Flow Body
Chordwise trailing flap movement into a flow body recess eliminates gaps, increasing lift coefficient while reducing mechanical complexity.
- Aircraft Leading Edge High Lift Assembly Support
An additional support device anchors the high lift body to restrict spanwise movement and deformation under air loads.
- Dual Actuator System with Dynamic Force Sharing
Dynamic force sharing between two actuators reduces wear and weight while maintaining reliability.
- Aircraft Seal Assemblies Reducing Drag via Damping
A dual-member seal assembly uses resilient layers and dampers to maintain smooth transitions between fixed airfoils and movable control surfaces.
- UAV Landing Site Determination Using Digital Elevation Data
A mapping engine identifies open areas for aerial vehicles by comparing digital surface and bare-earth models.
- Movable Wing Panel for Leakage Flow Reduction
Segmented movable panels reduce high-to-low pressure leakage flow through wing apertures while accommodating slat track movement.
- Aircraft Steering Vane Control System Asymmetric Rudder Deflection
A control system adjusts rudder deflection limits based on flight parameters to enhance steering authority.
- Aircraft Support Stay with Segmented Load Paths
Segmented aircraft support stays maintain failsafe operation by isolating load paths, reducing device complexity and space requirements.
- Trailing Edge Flap Segmentation for Lift
Segmenting the flap into a main and auxiliary element increases lift for heavy aircraft while maintaining a simple single-slot structure.
- Aircraft Slat Air Outlet Positioning for Anti-Icing
Positioning slat air outlets at the lower end directs exhaust flow into the boundary layer, preventing hot air impingement on the fixed leading edge.
- Leading Edge Flap Apparatus Reducing Drag and Weight
A leading edge flap apparatus uses a specific motion path to minimize drag during deployment.
- UAV Capacitive Sensor Propeller Stoppage
Capacitive sensors detect human touch on UAV surfaces to stop propellers, replacing heavy guards and improving airflow efficiency.
- Wing Tip Aileron Actuation via Bell Crank
Bell cranks mounted on the fuselage actuate ailerons via cables, bypassing wing pivot points to reduce moving mass and complexity.
