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.
- Aircraft Intake Bump Design for Boundary Layer Control
Wide bump design suppresses boundary layer flow into the intake while preventing lateral airflow concentration and air resistance.
- Motor Driven Cooled Compressor System Airflow Integration
Compressed air cools the electric motor while providing boundary layer suction, eliminating external ducting complexity.
- Swiveling Vane Flow Control for Aircraft Lift Augmentation
Rotating vanes adjust exhaust stream orientation to maintain Coanda attachment, enabling robust short takeoff performance without complex centralized control.
- Runway Surface Structure Accelerating Wake Turbulence Decay
Elevated ground structures create counter-rotating vortices that destroy primary wake turbulence, enabling reduced aircraft separation distances.
- Boundary Layer Ingestion Fans for Aircraft Drag Reduction
Segmented dedicated fans ingest boundary layer air to reduce drag without widening the fuselage structure.
- Aircraft Fuselage Front Section with Straight Cross Sections
Straight widening cross sections in the front fuselage section optimize volume distribution, resolving aerodynamic drag and manufacturing complexity trade-offs.
- Active Airflow System for Rotary Wing Drag Reduction
Active air generation system directs airflow through discharge openings to disrupt boundary layer airstreams, reducing drag on rotary wing aircraft.
- Angulated Aerodynamic Seal for High-Lift Flap Noise Reduction
An angulated aerodynamic seal reduces landing phase noise by segmenting flow control into outward and downward sections, resolving complexity trade-offs.
- Box Wing Aircraft With Swept Segmented Wings And Fuel Storage
A segmented box wing aircraft design distributes lift across three narrow wings to reduce structural span while maintaining total area.
- Perforated Aerodynamic Skin with Sandwich Panel for Boundary Layer Control
A perforated outer skin sheet and sandwich panel structure enable air flow through the component to manage boundary layers.
- Boundary Layer Transition Control via ICCAs
Imbedded Compact Control Actuators delay laminar-turbulent transition, reducing skin friction drag and aero-thermodynamic heating loads.
- Supersonic Waverider Aerodynamic Body Design
Waverider lower surface derived from shockwave of second axisymmetric body resolves contradiction between structural weight and volumetric efficiency.
