Power Installations TRIZ Cases
- Podded Engine Adaptor Simplifies Aircraft Mounting
An integrated podded engine adaptor consolidates multiple mounting interfaces to reduce installation time and complexity.
- Aircraft Drain Mast Airflow Suction Design
Drain mast pipe redirects airflow to eject fluid droplets perpendicular to the fuselage, preventing contamination and reducing parasite drag.
- RAT Generator Cooling Holes for Heat Removal
Integral inlet and outlet holes in the ram air turbine housing enable freestream air to cool the generator.
- APU Inlet Door Control via Feedback Failure Detection
A processing unit commands an auxiliary power unit inlet door to alternate positions when primary position feedback signals fail.
- Aircraft Fuel Cell With Cryogenic SMES Cooling
Passive cryogenic cooling of superconducting magnetic energy storage unit by liquid hydrogen eliminates active cooling weight and energy consumption.
- Constant Speed Drive for Variable APU Speed and Constant Generator Frequency
A constant speed drive decouples variable APU rotation from a generator shaft to maintain a target 400 Hz output frequency.
- Aircraft Fuel Cell Cooling via Shrouded Rotor Downwash
Rotor downwash ventilates the fuel cell heat exchanger, eliminating dedicated fans to reduce weight and energy consumption.
- Multilevel DC Power Bus Accumulator for Peak Load Management
An electrical accumulator arrangement pulses voltage across multilevel DC power bus rails to supply transient energy demands.
- Ducted Ram Air Turbine Assembly for Aircraft Pod Power
A ducted ram air turbine assembly generates electrical power and cooling inside an aircraft pod using adjustable inlet doors.
- Aircraft Moisture Control via Environmental Control System Valves
Dedicated valves redirect environmental control system airflow to crown region vents, eliminating heavy separate drying equipment.
- Airborne UAV Docking Assembly with Deployable Tug Device
An airborne docking system uses a segmented tug device and cable to extend the UAV flight range beyond fixed launch sites.
- Fuel Cell Powered Line-Replaceable Thrust Module for UAVs
Segmented fuel cell modules replace complex repairs, extending flight time while simplifying maintenance at remote operating locations.
- Electric Motor Takeoff Assist Device for UAVs
An electric motor takeoff assist device uses a battery-powered propeller to launch unmanned air vehicles.
- Gas Turbine Accessory System Internal Integration
Nests power devices inside the engine casing to eliminate external protrusions that cause aerodynamic drag.
