Fuselage Frames TRIZ Cases
- Aircraft Section Rapid Decompression Architecture for Simple Sidewalls
A separated rapid decompression unit and sidewall-floor gap simplify aircraft air removal while reducing certification and manufacturing complexity.
- Aircraft Fuselage Section With Tandem Fuel Tanks for Compact Routing
A caudal tandem layout for aircraft fuel tanks shortens routing space while spaced casings improve insulation and leak safety.
- Mandrel-Based Bladder Venting for Stiffened Composite Assembly
A layup mandrel routes atmospheric access to stringer bladders without perforating the vacuum sheet, reducing leaks, rework, and installation time.
- Removable Aircraft Tail Cones for ETOPS Weight Control
Swappable tail cones let aircraft use a lightened cone or an APU-equipped cone by flight category, reducing unnecessary weight and energy use while preserving ETOPS capability.
- Fuselage Collision Load Distribution via Wing-Support Connections
Support and wing units route collision loads across the fuselage, reducing direct impact transfer into the occupant space.
- Adjustable Aircraft Floor Module for Nose-Cone Alignment
Articulated forward and aft sub-modules accommodate fuselage alignment defects while transmitting vertical forces during aircraft nose-cone assembly.
- Curved Composite Aircraft Panels with Planar Stiffener Supports
RTM forms planar stiffener supports on curved panels, avoiding gaps and machining.
- Wing-Fuselage Truss Joint for Low-Bending Load Transfer
This aircraft case uses pivoting, segmented truss members to simplify wing removal and limit bending loads transferred to the fuselage.
- Net-Shape Composite Stringer Joggle Forming with Interchangeable Shims
A punch, die, and interchangeable shims form net-shape composite stringers with joggles, reducing ply wrinkling and resin pooling.
- CFRP Fuselage Frame and Clevis Securement for Tail Fin Shear Loads
CFRP frames and clevis fasteners transfer tail-fin shear loads without aluminum corrosion.
- Monolithic Aircraft Floor with Integral Cross Strut and Flush Seat Rails
Monolithic aircraft flooring cuts installation time, weight, and seat-rail corrosion risk.
- Flexible Liquid Collector for Aircraft Cabin Condensate Drainage
Flexible film collects aircraft cabin condensate while reducing drainage complexity and weight.
- Fuselage Circumferential Lap Splices Without Splice Straps
Complementary fuselage skins replace splice straps, reducing weight and assembly labor.
- Aircraft Fuselage Energy-Absorbing Structure for Hydrogen Tank Crashworthiness
A strut-supported fuselage structure absorbs 80–100% of crash energy before it reaches hydrogen tanks.
- Additive Manufactured Airframe Reinforcement for Torsional Strength
This case combines segmented additive-manufactured airframes with adhesive-bonded reinforcements to improve strength under torsional loads.
- Blended Wing Body Passenger Bays for Flexible Cabin Layouts
Segmented passenger bays enable flexible cabin layouts and improved space utilization.
- Two-Layer Composite Aircraft Skin with Retainers for Fail-Safe Bonding
Integrated retainers in a two-layer aircraft composite skin reduce bolt fastening while preserving fail-safe bonding support.
- Compact Flight Vehicle: Overlapping Propellers, Swappable Batteries
Overlapping propellers and swappable batteries support compact, extended flight.
- Aircraft Pressure Bulkhead Energy Absorption for Hydrogen Crash Loads
A deformable bulkhead section absorbs crash energy while preserving compartment pressurization.
- Aircraft Equipment Mounting Structure for Drill-Free Tolerance Compensation
Pre-drilled frames and eccentric adjustable brackets compensate for manufacturing tolerances during aircraft equipment installation time.
- Aircraft Stringers with CFRP-Reinforced Flanges for Impact and Buckling
Controlled CFRP flange reinforcement and ply-drop ratios address buckling, delamination, and wrinkle formation in aircraft stringers.
- Aircraft Structural Assembly with Rotating Connectors for CAD Interfaces
This aircraft assembly uses rotatable connectors to control OML and IML interfaces, reducing machining, tooling, mass, and cost.
- Aircraft Wing Pressure Fence Assembly for External Joining
Pressure fences define part of the pressure vessel while enabling external wing joining and parallel work during fuselage assembly.
- Aircraft Fuselage Fitting Structure for Secure, Accessible Disassembly
A butt-strap, connecting frame, and stabilizers create a secure fuselage joint that can be disassembled for tank maintenance.
