The production of aircraft engines requires very special materials to meet stringent quality standards and specifications. Operating at high altitudes and high speeds, and subject to many vicissitudes of nature such as cyclones, snow etc these engines have to be designed with zero tolerance against...
The chemistry behind the explosive mixture of oxygen and hydrogen
By: James Harris - 554809
