Drag Reduction TRIZ Cases
- Slotted Airfoil Lift Augmentation for Super-STOL Flight
Injector slots on the airfoil suction side boost laminar airflow and lift, enabling Super-STOL flight with less system complexity.
- Airfoil Injector Slots for Laminar Flow and Augmented Lift
Injector slots direct air from the leading edge across the suction side to sustain laminar flow, augment lift, and avoid external air intakes.
- Aircraft Lift Enhancement With Behind-Below-Wing Rotors
Rotor downwash can cause flow separation near wings; placing rotors behind and below the airfoil uses suction to increase lift and counter drag.
- Traveling-Wave Surface Actuation for Supersonic Shock Reduction
Actuators induce traveling waves along exposed surfaces to damp supersonic shocks, reduce turbulence, and limit material fatigue.
