Cosmonautic Vehicles TRIZ Cases
- Curved Arm Thrust Vector Control Mechanism
Segmented curved arms reduce system weight while maintaining precise six-degree-of-freedom positioning for thrust vector control.
- Payload Locking Mechanism With Segmented Pivot Latches
Segmented pivot latches engage grooved bolts to improve attachment reliability while managing device complexity.
- Pressure Relief Door Locking Mechanism for Aircraft Cargo
A pressure relief door integrates hinges with lock mechanisms and compression springs to secure the panel in an open position.
- Dual Stage Catalytic Thruster Thermal Standoff Cup
A catalytic thruster uses a thermal standoff cup to isolate the feed tube from reaction chamber heat.
- Micro-Cathode Arc Thruster Shape Memory Alloy Actuation
Replacing mechanical springs with a thermal-mechanical shape memory alloy actuator extends thruster lifetime while reducing system volume and complexity.
- Surface Density Modification of Porous Phenolic Bodies
Diffusing phenolic liquid into porous bodies increases surface density, resolving interface premature failure without raising bulk weight.
- Clockable Secondary Payload Bridge for Launch Vehicle Balance
Dynamic positioning of secondary payload bridges eliminates ballast requirements, preserving usable mass and targetable orbit energy.
- Bulkhead Triethylaluminum Container for Rocket Propellant Safety
Triethylaluminum in a bulkhead container reacts with leaking liquid oxygen, converting potential explosions into controlled fires.
- Variable Area Nozzle Ice Breakdown via Pressure Pulses
Actuating a variable area nozzle creates pressure pulses that remove ice without increasing fuel burn or engine weight.
- Satellite Reflector Boom Deployment for Launch Volume Constraints
Deployable boom rotates rigid antenna reflectors outboard to maximize aperture size within tight launch fairing envelopes.
- Missile Stage Jettison Control via Secondary Flight Computer
A secondary flight computer guides jettisoned missile stages along controlled glide paths to predetermined safe landing zones.
- Modular Launch Vehicle Configuration for Payload Adaptability
Segmented launch vehicle stages with standardized interfaces reduce unused mass by adapting engine cluster counts to specific payload requirements.
- Monolithic Resilient Joint for Deployable Structures
A monolithic joint uses a resilient flexure to store elastic energy for self-deployment of deployable structures.
- Satellite Trajectory Estimation Using Sequential Mode Correction
Sequential trajectory estimation updates satellite positions via thruster performance data, reducing iteration time for course corrections.
- Ion Thruster Gimbal Configuration for Stationkeeping
Offsetting maneuvers from ascending nodes reduces propellant consumption while eliminating the need for separate East/West propulsion systems.
