How Aircraft Engines Are Tested Before Production -

30/07/2020  Aircraft engines are meticulously engineered and manufactured. But once built, the engines are put through a relentless testing process. Here, we look at how aircraft engines are tested before production. Water and ice fired into the test engines. Engines can take in large amounts of water, so water ingestion tests are standard. At Boeing, planes taxi through specially made water troughs ...
