Chip detector | Aerospace | Eaton
better way to detect metal particles. I see and read about it. I read about engines that use these, aircraft engines. Sometimes good, other times not so good. Chip warnings ignored and fatal outcomes. Anyone have experience with these?
I had an idea.
I read some ideas.
I want to improve.
This is a patent for metal chip detector (by Pratt and Whitney) US10705038B2 – Systems and methods for detecting chips in fluid of aircraft engine – Google Patents
Notice the “chip size” object pointing to the indicator? In the drawing above. The improvement needs to be “chip mass” which is the mass of all the chips in the fluid or transmission. I have not seen how even chip size is reliably measured.
Is there another way? Of course! Not taking credit for this, just something I found. The idea that I read about used radioactive marking on the metal gears, and when the oil becomes radioactive, you know the gears are wearing fast. Great idea, perhaps not widely used because of radioactive fears.
