Efficient Propulsion Technologies TRIZ Cases

Stationary swashplate assembly translates flight control inputs to rotor blade pitch changes, eliminating rotating couplings and reducing mechanical complexity.

Dual-use motors drive rotors for takeoff and autorotate to recharge batteries, extending flight duration without adding generator weight.

A three-engine aircraft power plant regulates main and secondary engine groups using distinct setpoints for rotor frequency and output power.

Optimized gamma prime nickel-base superalloy composition enhances creep resistance at 1300°F through precise elemental balancing.

A variable diameter piccolo tube equalizes impingement flow rates across nacelle openings using a tapered cross-section.

Angled duct openings direct hot air to acoustic panels, optimizing flow concentration and defrosting efficiency while maintaining pneumatic pressure.

Stabilization chamber equalizes hot air temperature and pressure gradients to ensure uniform frost treatment on aircraft nacelle inner conduits.

Chopped prepreg tape cures via compression molding to form a fan case ice panel facesheet, eliminating manual layup and reducing manufacturing time.

A flexible panel assembly dynamically alters nozzle throat and exit areas to regulate secondary flow in gas turbine engines.

A rotor mounted at a shaft free end with an intermediate bearing reduces component count and weight.

Radial bosses on the thermal protection sheet or locking member provide mechanical support that reduces stress and prevents vibration in the locking member.

An enamel coating on ceramic matrix composites resolves wear resistance versus mechanical strength trade-offs by isolating the substrate from friction.

Biasing members position a ceramic blade track away from the central axis, reducing stress on brittle components during thermal expansion.
