Gas-Turbine Engine Testing TRIZ Cases
- Unducted Engine Testing With Passive Flow Conditioning
Passive ducts and pre-swirl vanes mimic flight-like airflow during ground tests, reducing propeller stall risk and improving power absorption.
- Borescope Centering Aid with Variable Radial Spacers for Stable Imaging
A variable radial spacer stabilizes the borescope head against chamber walls, maintaining image consistency during vibration.
- Continuous-Flow Engine Component Wear Detection via Oxidation Layers
Oxidation-layer thickness and surface distance enable non-destructive wear diagnosis for continuous-flow engine components and maintenance planning.
- Integrated Capacitance and Optical Probe Assembly for Gas Turbine Rotors
A shared probe combines capacitance and optical sensing to measure blade tip clearance and time of arrival while adding measurement redundancy.
- Mechanical Overspeed Protection Testing With Adjustable Spring Tension
An annular mount, trip sensor, and adjustable spring calibrate mechanical overspeed devices safely in laboratory tests.
- Gas Turbine Predictive Emissions Modeling Without CEMS
Remote physics-based and statistical models predict gas turbine emissions from operating data, reducing costly CEMS installation and maintenance.
- Automated Endoscope Inspection for Turbine Blade Screening
Manual endoscope rotation slows turbine blade checks; image screening selects blades for detailed observation while the rotor turns automatically.
- Heated-Wire Thermal Coking Sensor for Fuel Heat Control
Two heated wires detect fuel coking onset so a controller can regulate oil-to-fuel heat transfer and expand the fuel heat sink.
