Hello. I'm a HS junior at a research summer program and am researching Jet Engines. Apparently, when Jet Engines are used in tanks which move in deserts , the sand enters the turbines and corrodes them. In order to prevent that, would the solution be to implement a closed system so there is no contamination from the sand. One would need to figure out how to introduce new oxygen into the turbine for combustion.. Can you guys think of any other ideas? Thanks P.S: Filters would mean cleaning the filters sporadically and thus not making it the best solution..
