Aircraft Control TRIZ Cases
- Shape Memory Alloy Actuator for Composite Aircraft Structures
A shape memory alloy actuator integrated into composite aircraft structures changes from a buckled to an original form when activated.
- Avionics Unit Wireless Data Exchange via Memory Card Transceiver
A memory card transceiver enables wireless avionics data exchange, replacing tedious manual input and reducing update times.
- Aircraft Fairing Form-Fit Attachment Mechanism
Form-fit interlock joint secures aircraft fairing cover element to airfoil body, eliminating heavy brackets and reducing assembly time.
- Tethered Aerostat Attitude Control via Actuator-Managed Tether Lengths
Actuator-managed tether lengths adjust aerostat pitch, roll, and yaw to maintain dynamic stability during wind energy generation.
- Aircraft Thermal Anti-icing Bypass Housing
Crescent-shaped housing directs heated bleed air to the wing leading edge, isolating high-lift fittings from thermal exposure.
- Kinked Link Support for Aircraft Trailing Edge Panels
Pivot joints in the kinked link enable transverse routing installation while preventing airflow obstruction and reducing over-travel damage risks.
- Flight-Path Angle Calculation Using GPS and Airspeed
A computational method derives flight-path angle from indicated airspeed and vertical velocity data.
- Rotor Track and Balance Linear Optimization
A heuristic linear optimization algorithm adjusts pitch control rods, trim tabs, and hub weights to reduce aircraft airframe vibrations.
- Electro-Active Polymer Actuator with Flexible Retainers
Flexible strengtheners and retainer tips constrain electro-active polymer actuators to manage form changes during operation.
- Compound Aircraft Asymmetric Wing Flaps Anti-Torque
Asymmetric wing flaps generate longitudinal aerodynamic forces to create additional torque, reducing mechanical power demand from the main anti-torque device.
- Morphing Wing Device for Aerodynamic Flow Control
A morphing wing device alters aerodynamic flow over the external surface to reduce drag and delay stall across varying flight conditions.
- Rotary Actuated High Lift Gapped Aileron with Cove Lip Door
Repositioning the hinge line inside a lower surface cove reduces aerodynamic drag and slot blockage compared to conventional designs.
- Perforated Blade Seal for Aircraft Flap Noise Reduction
Segmented seals weaken merging vortices at high-lift flap edges, reducing aerodynamic noise without increasing drag or retrofit complexity.
- Compliant Rib Wing Camber Actuation
Actuator-driven compliant ribs deform wing contours via a sliding drive member to eliminate discrete control surface gaps that generate drag and noise.
- Vehicle Acceleration Control System for Fuel Efficiency Optimization
A vehicle acceleration control system adjusts input values to optimize fuel efficiency.
- Aircraft High Lift System Component State Monitoring
Comparing position measurements from drive stations and central power units detects component deviations in aircraft high lift systems.
- Aircraft High Lift System Convergent Gap Design
A wing depression positions the lift flap to form a continuously convergent gap, accelerating airflow via the Venturi effect to shift stall angles.
- Flight Management Vertical Trajectory Automation
A flight management system computes transition maneuver start points to establish vertical trajectories between departure and arrival waypoints.
