Engine Fuctions TRIZ Cases

Pre-heating outside air prevents moisture deposition on generator windings, extending component lifespan while recovering thermal energy from liquid cooling.

Tapered shafts enable higher fuel injection pressures by allowing localized deformation that prevents metal-on-metal bearing contact.

A turbine shroud cooling assembly directs fluid through microchannels in an inner shroud sealed by a thermal barrier coating.

A planar locking element uses an actuable spring to secure turbine blades within a hub assembly.

Reducing curvature in the vane suction side allows reliable cooling aperture creation, resolving thermal protection trade-offs.

A turbine nozzle reinjection duct redirects bypass fluid from the inter-wiper cavity into the main flow path.

A rotary motor uses levers to compress elastic components for energy storage.

Spring-loaded internal flaps deploy automatically via a sliding nacelle rear section, eliminating complex actuators and reducing aerodynamic drag.

A porous leading edge on outlet guide vanes dampens vibrations and suppresses airflow separation to reduce engine noise.

Additive manufacturing enables complex nozzle geometries that reduce casing distance and improve cooling efficiency without increasing weight.

Air ejector pump uses generator effluent flow to draw cooling air through a heat exchanger, eliminating noisy fans and reducing gearbox oil cooler size.

A roller slide drive mechanism coordinates turbojet thrust reverser deployment by delaying blocking door opening relative to movable cowl movement.

A quarter-wavelength resonator module couples to wind turbine components to induce destructive interference and reduce vibration amplitude.

A steam turbine control unit determines rotor stress using a simplified thermal model based on steam temperature measurements.

Segmented tip rails house microchannels that enhance cooling effectiveness and reduce leakage loss while minimizing compressor bypass air usage.
