NACA Type Air Intakes TRIZ Cases
- Combined Ram Air Inlet Layout for Low-Drag Aircraft ECS
A single ram air inlet feeds both the cabin pack and heat exchanger, improving pressure recovery while cutting drag, weight, and ECS complexity.
- Macrotextured Thermoplastic Duct Structure for Impact Resistance
Integrally molded depressions and crests help lightweight thermoplastic aircraft ducts absorb impacts and delay cracking during handling.
- Macro-Textured Thermoplastic Conduit Part for Impact Crack Resistance
Surface depressions and ridges help lightweight thermoplastic aircraft conduits resist tool-impact cracking while delaying damage onset.
- Aircraft Fairing Air Inlet Integrated With Structural Stiffener
An integrated fairing stiffener forms the air inlet, improving component cooling while preserving structural strength and reducing drag.
- Aircraft Fairing Air Inlet Integrated Into Stiffener Structure
Aircraft fairings can lose cooling access when stiffeners block inlet placement; integrating the inlet into the stiffener preserves strength and airflow.
- Ram Air Turbine Exhaust Compression Walls for Pressure Ratio
Aerodynamic compression walls accelerate free-stream air at the turbine discharge to increase total-to-static pressure ratio.
- Dual Inlet Precooler System for Aircraft Engine Nacelle
Segmented inlets with swept edges reduce total pressure losses and spillage, allowing larger precoolers closer to the fan.
- Y-Shaped Airliner Fuselage Design for Ultra-High BPR Engine Integration
A Y-shaped airliner fuselage bifurcates into angled extensions to house a medial fan and NACA inlet.
- Aircraft APU Inlet Diverter Fairing Aerodynamic Drag Reduction
Fixed diverter structures with S-shaped cross sections reduce excrescence drag and fuel burn by optimizing pressure recovery without mechanical actuators.
- Tandem Air Inlet Boundary Layer Modification for High Recovery
A tandem air inlet apparatus uses a forward flush heat exchanger inlet to swallow the boundary layer before it reaches the Pitot inlet.
- Aircraft Air Inlet Fluid Diverter Design
Raised intake opening with integrated diverter flanges prevents hazardous fluid ingestion while maintaining airflow performance.
- Aircraft Air Duct Flow Control Flap for Drag Reduction
A dynamic flow control flap adjusts the air duct inlet cross-section to minimize flight drag while maximizing ground airflow mass.
