Turbine/Propulsion Engine Ignition TRIZ Cases
- Flow Equalizing Override Assembly for Gas Turbine Fuel Divider
A flow equalizing override assembly adjusts fuel pressure via a remotely-actuatable valve to move a piston into an equalizing position.
- Gas Turbine Starter Generator Clutch Coupling
Clutch coupling starter generator to low pressure compressor eliminates tower shafts and gear systems, reducing axial length.
- Gas Turbine Active Clearance Control Warm Start Management
Controller applies decay function to cooling schedule adjustments during warm start, reducing thermal expansion and preventing turbine blade rubbing.
- Turbomachine Compressor Rotating Stall Suppression
A turbomachine control system detects surge events and restores the surge margin by adjusting fuel flow and stator pitch angles.
- Gas Turbine Startup Flow Control for Thermal Management
A flow control device directs hot gas path air through a conduit to heat turbine stationary components during engine startup.
- Gas Turbine Rotor Startup Speed Control
A gas turbine rotor assembly maintains rotational speed within a defined range to equalize thermal gradients before reaching combustion velocity.
- Turbine Engine Variable Stator Vanes Thermal Bow Control
FADEC controls variable stator vanes and starter power to mitigate thermal rotor bow deformation, preventing contact damage in high bypass ratio engines.
- Mobile Power System Segmentation for Well-Site Installation
Segmenting the gas turbine generator and exhaust starter onto two transport vehicles reduces well-site installation time from weeks to hours.
- Aircraft Reservoir Liquid Pre-heating via Motor Locking
Locking the electric motor rotor prevents pumping and transfers thermal energy to cold reservoir liquid, reducing warm-up time before engine start.
