AI Technical Summary
Existing aerospace engine endoscopes cannot operate stably and precisely under high temperature and high pressure environments. Traditional cooling methods are costly or have limited cooling range, affecting imaging quality and measurement accuracy.
It adopts a dual-system structure combining liquid cooling and air cooling. Through nested cooling devices, it utilizes air-cooled film columns and spiral water flow design to achieve efficient cooling. Combined with high-temperature resistant materials with nickel alloy and zirconium oxide coating, it can adapt to complex and narrow environments.
At a high temperature of 1800℃ and an atmospheric pressure of 35MPa, the endoscope maintains stable operation below 200℃, ensuring imaging quality and measurement accuracy, reducing costs, and adapting to various optical tube requirements.
