Efficient Propulsion Technologies TRIZ Cases

Integrated electromagnetic brake on motor shaft reduces required motor size while maintaining stable attitude-angle control during hovering.

Segmenting the nacelle lipskin into concentric parts reduces manufacturing complexity and eliminates ripples that disrupt laminar airflow.

Radially extending intersegment seal tabs define cavities that pump hot gas path air into gaps to heat attachment regions and reduce thermal stress.

A turbine ring assembly uses ceramic matrix composite segments to house a metallic holding member for structural support.

Depth-reduced inner circumferential sections in a turbomachine drum receptacle structure ensure correct guide blade group alignment.

Front and rear tooling stabilizes the propulsive assembly during vertical tilting to prevent damage from insufficient intermediate casing strength.

Inflatable bladder pressure cures the double-walled composite fan inlet housing, eliminating core collapse during high-pressure molding.

Coaxially aligned pump gear system reduces device complexity and maintenance costs by merging separate pump assemblies into a single integrated unit.

A continuous compression molding tool shapes and consolidates prepreg material using interchangeable dies to produce composite body portions.
