Air Braking Surfaces TRIZ Cases
- Monolithic Aircraft Structure With Friction Stir Welded Aerodynamic Surfaces
Friction stir welding joins body and cover components into smooth aerodynamic surfaces, cutting aircraft weight, drag, and fastener assembly work.
- Towed Refueling Boom Control for Concurrent In-Flight Refueling
Deployable aerodynamic panels stabilize a towed refueling boom, enabling precise concurrent in-flight refueling of multiple aircraft.
- Deployable Wing Structure for Descent Control in Flying Objects
A forward-deploying wing section increases drag to slow descent and stabilize attitude, then retracts to limit cruise energy use.
- Leading Edge Surface for Lift Control in Low-Volume Wings
A retractable leading edge surface replaces multiple wing control surfaces to manage lift while saving wing space, weight, and complexity.
- Rotor Blade Flap Braking for Air Vehicle Mode Transition
Blade-mounted flaps add drag to decelerate and stabilize a rotor, enabling smoother air vehicle transition from rotary to winged flight.
- Aircraft Spoiler Movement Limiter for Power-Linked Maintenance
A mechanical limiter blocks spoiler deployment until external power is disconnected, creating a safer maintenance sequence with fewer parts.
- Aircraft Spoiler Power-Connector Interlock for Safe Maintenance
A mechanical interlock blocks spoiler deployment when external power is connected.
- Aircraft Spoiler Optimization for Takeoff Drag and Lift
Dynamic spoiler adjustment resolves the contradiction between maximum fineness and high drag during rolling, enhancing takeoff efficiency.
- Aircraft Speed Brake Asymmetric Flap Extension
An asymmetric flap extension disrupts symmetrical vortex formation, reducing pressure fluctuations and resonance risks while maintaining braking force.
- Segmented Aircraft Spoiler with Articulated Drive Mechanism
A segmented spoiler design articulates multiple segments about a transverse axis to adjust inclination angles independently.
- Avionic Display System for Vertical Situation Instability Prediction
Controller generates optimized drag device deployment cues on a vertical situation display to prevent unstable aircraft states during approach.
- Wing Assembly with Movable Spoiler and Flap for Short Takeoff
A wing assembly integrates a spoiler on the upper surface and a flap on the lower surface to increase control area.
- Slotted High Lift Aerofoils With Mild Stall Ramp
A slotted aerofoil uses a blunt leading edge and mild stall ramp to maintain lift at high angles of attack.
- Mechanical Droop for Aircraft Spoiler Operation
A torque tube drives a gearing assembly to rotate an eccentric member, translating a linear actuator.
- Aircraft Spoiler Releasable Aft-Section Design
Segmented spoiler design uses a mechanical release to disengage the aft-section during backdrive events, reducing system weight and repair costs.
- Aircraft Slat Seal Door Monolithic Locking Mechanism
Monolithic seal locking mechanism reduces aircraft weight by merging door panel, locking members, and coil spring into a single integrated assembly.
- Lower Wing Spoiler for Aft-Loaded Aircraft Wing Load Alleviation
A deployable lower wing spoiler causes flow separation to reduce lift on aft-loaded aircraft wings, alleviating root bending moments during turbulence.
- Stowable Bell-Mouth Scoop for Gas Turbine Reverse Thrust
Hinge members rotate a bell-mouth panel from a stowed position to deployed, reducing air separation at the nozzle opening during reverse thrust operations.
