Power Plant Construction TRIZ Cases

Integrating a heat exchanger into the engine pylon structure reduces nacelle space requirements while maintaining effective cooling capacity.

A movable downstream cylindrical nacelle structure pivots to expose internal components for maintenance.

A drone frame uses a strip engagement portion to mount propulsion elements at variable positions along the central body.

Segmented mounts transfer axial thrust and radial loads separately, preventing pitch moments that increase outlet guide vane stress.

Hinged links absorb thrust forces at the aft attachment, reducing bending moments on the rigid structure.

An auxiliary power unit supplies restart energy to a hybrid turboshaft engine in standby mode, eliminating heavy onboard storage and reducing system weight.

Segmented fittings with orthogonal pins distribute stress to reduce bulk, enabling additional systems installation in the constrained leading edge region.

Disposable protection pieces with co-operating shapes prevent lug wear from thrust forces, eliminating grinding operations that reduce structural integrity.

Dual pressure taps drive a turbocompressor to manage airflow, reducing engine efficiency losses from high-pressure air diversion.

Lateral and transverse braces distribute mechanical loads, reducing primary structure dimensions by 20-40% while minimizing aerodynamic drag.

Asymmetric attachment placement and third-dimensional load paths reduce fan frame ovalization, improving structural integrity and turbojet performance.

Axially shifted rear engine attachment reduces width and mass, eliminating aerodynamic disturbances from inter-turbine casing links.

Aircraft engine attachment uses a viscoelastic stacked layer to absorb vibrations and thermal movements.

Accessory boxes link engine casings to absorb thrust, reducing bending stresses and shortening connecting rods.

Preliminary anti-action elastic devices absorb forces and reduce flexural deformation in ultra-high bypass ratio engines.

Vertical pins orthogonal to the force transmission plane enable straightforward engine attachment, eliminating complex inclined tooling requirements.

A single-piece fire resistance device with a C-shaped contact lip and beaded segment prevents flame propagation between an aircraft turbomachine mounting strut and cowling.

Segmented front engine attachment manages high double flux engine weight by distributing forces across orthogonal load paths.
