Power Installations TRIZ Cases
- Ram Door Fairing for Auxiliary Power Unit Intake
A ram door fairing directs airflow into an auxiliary power unit intake duct, reducing drag by up to 14.9%.
- Aircraft High Voltage Power Conduit with Dielectric Gas Insulation
Dielectric gas insulated conduit transmits aircraft electrical power above 270V, reducing cable weight while preventing corona discharge effects.
- Rigid Fixture for Aircraft Electronics Rack Transportation
A rigid fixture system secures aircraft electronics racks during assembly and transport using lateral clamps and removable covers.
- Auxiliary Power Unit Mechanical Coupling for Aircraft Taxiing Thrust
An auxiliary power unit mechanically couples to high and low pressure spools via a reduction gearbox to supply rotational power.
- Direct Electric Drive Aircraft Propulsion System Weight Reduction
A direct electric drive system couples a polyphase generator to an electric motor for aircraft propulsion.
- Hybrid Pneumatic Electric Cabin Energy System for Aircraft
APU drives load compressor and generator to supply cabin air, eliminating redundant generators and reducing aircraft weight.
- Aircraft Dual Hybrid Energy System Transient Power Management
Segmented dual hybrid energy system supplies transient power spikes via ultra-capacitors, reducing generator size and extending battery life.
- Landing Gear Wheel Lighting for Electric Taxi Identification
Lighting arrangement on landing gear wheels identifies electric taxi-equipped aircraft, resolving ground visibility conflicts without fuselage markings.
- Tail Cone Auxiliary Jet Engine Mounting Structure
Overhanging beam structure secures an auxiliary jet engine in the tail cone, eliminating separate APU mass and noise.
- Aircraft APU Suspension System Sliding Mounts
Sliding fuselage brackets on longitudinal elements reduce dynamic amplification and improve reliability.
