1999 NASA Hypersonic X-43

NASA has established an experimental hypersonic test program called Hyper-X. The program utilizes an “air-breathing” engine technology for use in future reusable space launch vehicles. While conventional rocket engines are powered by mixing fuel with oxygen, both of which are traditionally carried onboard the aircraft, the Hyper-X will carry only its fuel – hydrogen. The oxygen needed to burn the fuel will come from the atmosphere. The benefit to future launch vehicles is increased payload capacity because the heavy oxygen tanks that a typical rocket must carry are no longer required. Makel Engineering was selected to provide the hydrogen safety sensors for Hyper-X, and continues to provide systems for this ongoing program.
