Engine Control TRIZ Cases
- Rocket Engine Nozzle Needle Pneumatic Thrust Control
Pneumatic nozzle needles adjust thrust rapidly by varying gas pressure in compensation and control chambers, resolving slow mechanical positioning times.
- Variable Speed Pump Control for Water Supply Energy Reduction
A water supply pump controller switches between multiple head curves to lower rotational speed while maintaining constant flow rates.
- Hydraulic Control System for Thrust Reversal and Variable Nozzle
A hydraulic control system segregates thrust reversal and variable nozzle operations using single-action actuators.
- Rocket Engine Pressure Control via Model-Based Mixing Ratio Estimation
A pressure feedback loop delivers control signals to engine valves while a model estimates the mixing ratio from valve positions and measured pressure.
- Thrust Reverser Actuation Mechanism for Aero Engine Nozzle Control
A thrust reverser actuator uses a drive rod to pivot panels while maintaining rectilinear cowl movement.
- Ceiling Fan Infrared Detection Rotatable Lens
Rotatable lens adjusts infrared detection range to avoid false pet activation.
- Hydraulic Turbine Pressure Control Device Energy Recovery
A hydraulic turbine pressure control device recovers energy from water flow using a Francis-type design.
- Thrust Reverser Actuator Flow Limiter
A hydraulic flow limiter reduces pump capacity requirements by regulating actuator pressure draw during thrust reverser deployment.
