Engine Manufacture TRIZ Cases

This aircraft powerplant uses generator and motor coupling to vary propulsor speed independently from combustion operation.

This case uses higher-resistance material near the tip and lower-resistance material inboard to reduce cost and preserve aerodynamics.

This turbine blade case uses coordinate-defined curved rib geometry to reduce channel-turn stress and improve cooling efficiency.

A downstream heat exchanger uses parallel, equidistant channels to distribute turbine exhaust heat evenly for stable steam generation.

Radar-absorbing particles in a fiberglass or carbon-fiber layer work with a reflective layer to reduce turbine radar reflections.

Airfoil, wedge, and chevron features in internal cavities generate vortices that improve convection and film cooling.

A converging Y-shaped linkage retracts from the bypass flowpath, reducing cruise drag while retaining thrust reverser actuation.

This case uses protruding setter posts to hold ceramic core segments apart during firing, improving wall-thickness consistency.

A clamped piston and limit switch guide stopper insertion into metal root inserts, reducing errors, damage, and assembly time.

Scanning and inertial measurement locate the center of gravity, enabling stable lifting without oversized wind turbine yokes.

Replacing reversing doors with flexible sails and rotating arms diverts secondary flow while reducing turbofan engine mass.

An aircraft engine nozzle uses an internal actuator and strut carriage to translate the sleeve axially and control radial loads.

The equipment support mounts to the intermediate casing hub, avoiding compressor casing distortion and simplifying attachments.

This case segments compressor flow turning across tandem stator rows to limit separation and preserve efficiency across transonic operation.

This case uses segmented tandem vane rows to manage incidence variation, reduce aerodynamic losses, and improve compressor surge margin.

Adaptable placement tools improve flatback blade component accuracy and assembly speed.

This turbine airfoil case uses a trailing-edge lobe to reduce combustion-gas noise while maintaining flow angles and throat widths.

Detachable nacelle modules use closable access openings and automatic connections to speed component replacement and maintenance.

This case uses controlled induction heating to soften adhesive bonds and remove inserts while preserving laminate structural integrity.

A coordinate-defined inner rib profile uses smooth transitions to reduce stress at coolant-channel turns and extend blade life.

Hydraulic cylinders, cables, and pulleys redirect blade loads and align the CoG for crane-free insertion in tight hubs.

A floating intervention platform uses ballast control and a heave plate to limit motion during deepwater wind turbine work.

This case routes gas from the inner head cover into the water passage, reducing cavitation and vibration with minimal modification.

Tapered damper pockets and bodies dissipate vibrational energy in integrally bladed rotors, helping limit High Cycle Fatigue damage.

A sintering-aid slurry forms dense EBCs at lower temperatures, helping block steam and oxidation in ceramic components.

This turbine nozzle case uses zoned trailing-edge slots and baffle-insert cooling holes to limit thermal gradients and improve durability.
