Engine Manufacture TRIZ Cases

Learn how a pivotable lever arm keeps a wind turbine counterweight compact during initial lifting, then creates balancing moment without a power source.

Non-orthogonal, non-parallel shear webs form a V-configuration that resists blade shear distortion without X-shaped reinforcement.

A synchronization ring and articulated connecting rods coordinate nozzle flaps to widen A9/A8 ratios without a bulky control system.

During a loss-of-oil event, a controller actuates a seal to vent impeller-cavity gases, lowering axial shaft loads and bearing temperature.

Discontinuous composite filling stabilizes the blade trailing edge while reducing adhesive, reinforcement use, and overall blade weight.

Varying rotor-hub radius changes airfoil spans and natural frequencies, reducing coherence with unsteady pressure fields that drives flutter.

Complex connecting passages make cast engine components difficult to manufacture; bounded core geometry supports target flow and material properties.

Nested airfoil and shank passages route cooling fluid through turbine blades while limiting added complexity and improving creep and fatigue resistance.

Varying suction-side geometry, conduit area, and conduit count targets turbine-airfoil cooling to reduce creep and fatigue.

Routing cooling air through the web toward a central chamber helps limit trailing-edge pressure differentials while preserving sealing effectiveness.

Learn how varied conduit geometry distributes cooling fluid through a turbine blade to limit thermal stress and improve durability.

Undulating shroud tangs create an interference fit with stator vanes, improving support and sealing while reducing engine vibration.

Composite fan blades overcome metal size limits, enabling larger, lower-solidity turbofan fans for improved efficiency and thrust output.

Heat shields form air gaps around axial spokes to limit combustion-gas heat transfer, reducing thermal distortion and stabilizing turbine tip clearance.

Machining airflow passages into a solid airfoil body and enclosing them with a cover addresses casting limits while enabling active heating and cooling.

A fixed support plane on the blade root stabilizes wind turbine blades in a defined orientation during transport and storage.

Irregular steps and gaps between assembled turbine blades can create secondary vortices; curved endwall contours guide flow and reduce aerodynamic loss.

Angled ribs below 90 degrees form a flexible truss and staggered cavities, allowing turbine airfoil walls to expand and reducing thermal stress.

Segmented cooling conduits distribute fluid through the airfoil, improving heat removal while supporting blade durability under thermal and mechanical stress.

A root-mounted cooling air deflector with an aperture guides plenum air into rotor-blade passages while limiting swirl and stagnation.

Uniform blade modes can amplify turbine vibration; varied axial sweeps introduce mistuning while preserving blade performance and limiting material changes.

Pre-assembling the collapsible rotor in a plant lets contractors unbundle and extend it on-site, reducing assembly effort and equipment needs.

An asymmetric blade-tip thickness profile raises local flow velocity, reducing pressure differentials and leakage without increasing clearance.

A circumferential gap routes a drive shaft through the air intake while screens and guide struts smooth compressor airflow and reduce assembly size.

Non-uniform stator vane spacing shifts harmonic response and reduces vibratory-response severity across engine speeds.

Larger cooling channels can weaken rotor blades; localized wall thickness and angled interfaces balance cooling air flow with structural strength.

Parallel shafts drive a tensioned abrasive belt to shape wind turbine blade leading edges with less manual effort and longer abrasive life.

Centrifugal oil from the reduction gear is recovered and routed to guide bearings, reducing oil demand and simplifying the turbomachine lubrication circuit.

A U-shaped route stores extra high-voltage cable inside the tower, easing transport and switchgear connection for taller transition pieces.
