Space Shuttle Engines
Each space shuttle main engine operates at a liquid oxygen liquid hydrogen mixture ratio of 6 to 1 to produce a sea level thrust of 179 097 kilograms 375 000 pounds and a vacuum thrust of 213 188 470 000 pounds.
Space shuttle engines. Each space shuttle main engine operates at a liquid oxygen liquid hydrogen mixture ratio of 6 to 1 to produce a sea level thrust of 179 097 kilograms 375 000 pounds and a vacuum thrust of 213 188 470 000 pounds. And the available information focuses on the vehicle powered by the engine the vehicle mission and successful or failed launches rather than the engine itself. See how the shuttle uses solid rocket boosters engines and external fuel to get off the launch pad.
At their full power that was equivalent to the output of 13 hoover dams. Crewed orbital launch and reentry. T minus 6 6 s the shuttle s main engines ignite one at a time 0 12 s apart.
Launching the space shuttle launching the space shuttle requires massive thrust. The nozzle is a bell shaped extension bolted to the main combustion chamber referred to as a de laval nozzle the rs 25 nozzle has an unusually large expansion ratio about 69 1 for the chamber pressure. At sea level a nozzle of this ratio would normally.
The engines build up to more than 90 percent of their maximum thrust. The engine s nozzle is 121 in 3 1 m long with a diameter of 10 3 inches 0 26 m at its throat and 90 7 inches 2 30 m at its exit. The sts 1 mission relied on brand new technologies that had never been used before.
Lockheed martin martin marietta et. The space shuttle s three main engines operated for 8 minutes and 40 seconds for each shuttle flight with a combined output of 37 million horsepower.
