Efficient Propulsion Technologies TRIZ Cases
- Desiccant-Assisted Intercooler Cooling for Humid Gas Turbine Air
By drying ambient air before evaporative chilling, this case restores intercooler cooling in humid conditions and boosts gas turbine output.
- Compressor-Driven Generator Layout for Turbine Engine Cooling
By moving the generator rotor onto compressor blades and cooling the stator with bypass airflow, this case cuts heat, weight, and access issues.
- Hybrid Electric Engine Battery Dispatch by Flight Waypoints
Flight-plan and battery-state control assigns electric motor use by waypoint to preserve battery reserve, improve fuel use, and avoid extra power systems.
- UAV Motor Voltage Control to Prevent Thrust Saturation
Motor voltage is adjusted from flight state and environment data to keep UAV thrust within a controllable speed range and avoid power saturation.
- Hybrid Aircraft Power Distribution for Battery Reserve Control
Flight-plan waypoints shift battery and fuel power by flight stage, improving hybrid aircraft efficiency while preserving battery reserve.
- Hybrid Rotorcraft Power Split for One-Engine-Inoperative Capability
Two smaller thermal engines plus an electrical machine meet OEI power needs in rotorcraft while cutting weight, fuel use, and maintenance.
- Magnetic Rotor Locking for eVTOL Drag Reduction
A magnetic lock holds unused eVTOL rotors stationary in flight, cutting drag while allowing rapid release when propulsion is needed.
