Power Installations TRIZ Cases

A holdup capacitor and redundant supply are switched at a voltage threshold to keep aircraft DC output stable during outages.

Interlocked finned spar members hold compressed batteries inside aircraft structures, cutting payload weight while maintaining containment and strength.

Directly coupling fuel cell groups to an aircraft DC bus removes voltage converters, improving power distribution efficiency and redundancy.

A nonflammable hydrogen-helium lift gas boosts buoyancy and feeds fuel cells, avoiding separate hydrogen tanks in LTA craft.

Integrated feeders and collectors within a fuel cell support cut attachment points, save aircraft space, and lower connection leakage risk.

Piezoelectric plates on rotor blades turn aerodynamic strain into electrical power while limiting stiffness change and preserving blade aerodynamics.

Selective branch disconnection and low-voltage standby cut switch leakage currents, reducing idle power dissipation and extending limited power source life.

Closer cooling outlets and separate lubrication outlets help toroidal CVTs cool the power roller faster while reducing oil scatter.

Dual hydrogen supply lines switch between variable and constant pressure to sustain fuel cell power during low-tank-pressure emergency landing.

An electric motor-driven compressor, heat exchanger, and turbine replace engine bleed air to manage cabin pressure, temperature, and wing anti-icing.

By embedding identification signals in control commands, the aircraft EMS can detect which flexible loads are active from aggregate power use.

By tagging control signals and reading them in aggregate power use, the EMS can verify which aircraft loads are actually on and avoid wasted control actions.

A liquid-air heat exchanger, pump, and flow restrictor keep aircraft batteries warm during cold soak to preserve capacity and range.
