Fuselage Frames TRIZ Cases

A heliplane craft uses counter-rotating propellers and adjustable wing flaps to transition between vertical hover and horizontal flight.

Bonding a carbon fiber splice to metal frames slows crack propagation, extending inspection intervals without adding significant mass.

Three-dimensional printing produces monolithic structural components integrating aircraft systems to reduce part count and weight.

Vertical curing with an expandable mandrel prevents sagging, enabling parallel frame fabrication that reduces bracing needs.

Bending a structural component along the mat axis creates a continuous curved surface that eliminates thermal bridges and reduces installation time.

A tapered fuselage splice fitting connects strap and stringer components with uniform thickness to enable a shimless joint.

A gas permeable layer underlying decorative laminates allows entrapped gases to escape during application.

Segmenting prepreg tows into independently controllable regions allows pulsed heating to maintain adhesion during tight curvilinear placement.

A vertical interconnection strut bridges adjacent aircraft flaps using a compensating profile and guidance arms.

Relocating access holes to the cover maintains side panel integrity, reducing stress concentrations under bending loads.

Framework-like connecting elements decouple thermal expansion and mechanical movements in a fuselage mounting assembly, reducing structural damage risks.
