Efficient Propulsion Technologies TRIZ Cases
- Integrated Heat Pump Engine for Fuel-Free Ambient Heat Recovery
A nested compressor-turbine layout converts atmospheric or seawater heat into mechanical power without fuel, cutting complexity and pollution.
- Hybrid Aircraft Propulsion with Generator-Driven Ducted Thrusters
Generators on the main aircraft engines power ducted propulsor modules, boosting thrust without extra thermal engines, weight, or complexity.
- Hybrid Aircraft Propulsion with Fuel Cell Base and Peak Thrust Split
A fuel cell handles cruise thrust while combustion engines add take-off and climb power, cutting emissions without the weight of full fuel cell propulsion.
- Composite Turbomachine Preform Pressurization for Low-Porosity Molding
A flexible fluid pocket adds controlled internal pressure during polymerization to improve resin impregnation and limit porosity in turbomachine composites.
- Electric Machine Idle Assist for Symmetric Aircraft Taxi
Electrical torque assists turbine engine spools at idle, cutting taxi fuel burn while avoiding asymmetric thrust and poor ground handling.
- Multi-Function Fixed Structure for Compact Cascade Thrust Reversers
An integrated fixed annular structure guides grids and deflects reverse flow to cut thrust reverser mass, volume, and assembly complexity.
- Rotorcraft Hybrid Power Plant Control for Autorotation Assistance
Adaptive control of heat engines and electric machines uses density altitude and power demand to support autorotation and reduce fuel use.
- Multi-Functional Thrust Reverser Structure for Lower Mass and Drag
An integrated fixed structure guides cascades and deflects reverse flow to cut thrust reverser mass, drag, and architecture complexity.
- Modular Aerial Vehicle Assembly for In-Field Mission Reconfiguration
Reversible modular sections let field users reconfigure an aerial vehicle for changing payloads and missions while cutting development time and cost.
