Fuel Systems For Specific Fuels TRIZ Cases
- Double-Walled Fluid Line with Sliding Outer Sleeve for Static Sealing
A sliding outer line uncovers coupling ends for assembly while static seals protect high-pressure fluid connections from leakage and wear.
- Segmented Laser Peening Probe for Internal Hydrogen Passages
Articulated probe segments and contactless spacing enable laser shock peening of complex internal passages to delay hydrogen embrittlement.
- Double-Walled Fluid Line Assembly for Sealing and Service Access
A movable outer line covers coupling ends for static sealing in high-pressure fluid transport, then slides back to simplify assembly and disassembly.
- Aircraft Fuel Switching for Contrail Suppression Control
Alternating between two aircraft fuel compositions cuts contrails while reducing the cost and weight penalty of continuous suppressing fuel use.
- Aircraft Engine Fuel Switching Between Jet Fuel and SAF
Separate storage and phase-based switching between jet fuel and SAF helps extend aircraft range while cutting emissions and contrails.
- Aircraft Hydrogen Distribution With Helium Heat Transfer for Pump NPSP
A helium heat transfer circuit raises hydrogen pressure at the pump inlet, enabling low-pressure tanks and stable NPSP.
- Aircraft Combustion Chamber with Constant Hydrogen, Variable Liquid Flow
Constant hydrogen flow with variable liquid-fuel delivery improves aircraft combustion efficiency and reduces particulate and NOx emissions.
- Aircraft Dual-Fuel Combustion Control Using Constant Hydrogen Flow
This case varies liquid fuel flow while holding gaseous fuel constant to reduce particulates and NOx in dual-fuel aircraft engines.
- Non-contact Optical Fuel Gauging via External Sensor
External optical sensors measure fuel levels through tank walls, eliminating in-tank wiring and reducing maintenance downtime.
