Turbine/Propulsion Engine Cooling TRIZ Cases
- Aircraft Engine Heat Exchanger Shielding Hydraulic Reservoir
Heat exchanger outer walls shield an overlapping area with a hydraulic fluid reservoir, reducing dead weight and manufacturing costs.
- Hot Gas Path Cooling System with Particle Collection Chamber
An angled access passage directs cooling fluid into a particle collection chamber, preventing blockages in hot gas path components.
- Diffuser Case Heat Exchanger for Bleed Air Cooling
Integrating a heat exchanger within the diffuser case cools bleed air via bypass flow, resolving thermal management complexity in gas turbine engines.
- Turbine Bearing Chamber Pressurization Using Upstream Air
A turbine bearing chamber pressurization system supplies cold air from upstream of the low-pressure compressor to maintain lubrication integrity.
- Inlet Turning Vanes With Trailing Edge Notches
Trailing edge notches on inlet turning vanes mix pressure and suction side air streams to reduce total pressure loss in gas turbine bypass ducts.
- Turbine Conduit Heat Exchanger Bypass Flow Control
Segmented heat exchanger by-passes balance pressure and temperature gradients, preventing flow reversals in gas turbine engines.
- Gas Turbine Fuel Heating via Oil Heat Exchange
Parallel oil loops raise fuel temperature to 135°C while air cooling prevents coking risk.
- Gas Turbine Cooling Plenum Heat Exchanger Integration
Integrating a heat exchanger into the gas turbine cooling plenum lowers component temperatures, allowing smaller clearance gaps and improving engine efficiency.
- Gas Turbine Buffer System Cooling Shafts
A buffer system communicates conditioned cooling air to gas turbine engine shafts and bearing structures.
- Hybrid Heat Exchanger Combining OGVs and Surface Coolers
A heat exchanger system merges outlet guide vane units with surface coolers to expand cooling capacity.
