Turbine end: Impeller 100,000 RPM, balance accuracy within 0.01mm, otherwise easily broken; exhaust pulse causes oxide layer.
Compression end: Compressor impeller centrifugal compressed air, intercooler cooling efficiency is key (10℃ reduction in intake temperature, 1.5% increase in power), high-end models use water-cooled intercoolers.
Bearing system: Fully floating bearings, oil film ten times finer than a human hair; 600℃ exhaust requires nano-ceramic coated bearings, increasing lifespan by 3 times; oil filter needs to be replaced every 500 hours to prevent oil film breakdown.
Sealing system: Leak-proof sealing rings, improved carbon fiber sealing rings maintain a 0.01mm gap at 150,000 RPM, precision exceeding that of a Swiss watch.
