The RS-25, which is the official designation of the SSME (Space Shuttle Main Engine), is composed mostly of a network of various pumps and valves that prepare the propellant for combustion. Like the engines of the rockets before it, the space shuttle's engines work by combining a fuel with an oxidiser (that is, an oxidising agent) and igniting the resulting mixture. This two-part propellant is necessary because fire needs oxygen to burn, and there is no oxygen in space; the oxygen is thus supplied by the oxidising agent.

For the SSME, liquid hydrogen is used as the fuel and liquid oxygen as the oxidiser. These enter the shuttle from the orange external fuel tank (ET) through separate fuel lines. Turbopumps increase the pressure of each propellant component, preparing it for the combustion chamber (higher pressure causes more thrust). The components (which are still kept separate at this point) go through a number of other pathways that are annoyingly technical to describe (for an in-depth description of the processes, check out the related link at the bottom of this answer); for example, some fuel and oxidiser go directly to the main combustion chamber (MCC) and are ignited, while some fuel goes instead to a pipe around the nozzle and acts as coolant to prevent it from overheating, while some oxidiser is converted to gas and used to pressurise the oxidiser tank.

Ultimately, though, the fuel and oxidiser are combined in the MCC and ignited. The resulting combustion and expulsion of the burning mixture through the SSME nozzle produces a lot of thrust--1859 kN of thrust at sea level, and 2279 kN in a vacuum (space).

What is a engine used on a spaceship?

There are actually two types of boosters that were both used by the space shuttle before their decommission. To propel the vehicle out into space from the surface of the earth out past the atmosphere, the shuttle used SRB's, or Solid Rocket Boosters. The engines on the actual shuttle are LRB's, or Liquid Rocket Boosters. These are used to propel the space vehicle further into space and into orbit around the earth.


What is a shuttles main engine powered by?

The Space Shuttle main engines are powered by a combination of Liquid Oxygen (LOX) as an oxidizer and Liquid Hydrogen (LH2) as a fuel. Both propellants are stored in the space shuttle's External Tank during launch. They are fed into the space shuttle's main engines by umbilical lines on the external tank, and then the orbiter's main propulsion system feed lines. The Space Shuttle's main engines can achieve a thrust level of about 512,300 pounds, which is greater than 12,000,000 horsepower.


Should you replace the space shuttle with a jet engine and carbon steel or provide stronger steel to jets to go into space?

A jet engine cannot take you into space as there is no air in space to provide the jet engine with oxygen. Also metals cannot survive reentry as they melt and burn up, unless protected by some type of heat shielding material..


How many trips did the Space Shuttle Columbia make?

The space shuttle Columbia completed 27 successful space flights, not including its final flight whereupon it was destroyed in the Earth's atmosphere. It was the only shuttle apart from the Challenger never to dock with the Mir Space Station or the International Space Station.


What kind of engine does the space shuttle have?

The Space Shuttle Main Engines (SSMEs) also known as the RS-24 engines are liquid fueled reusable engines made by Rocketdyne and burn liquid hydrogen as their fuel and liquid oxygen as the oxidiser. The shuttle has three engines. The fuel is stored in the large orange External Tank strapped to the shuttle's belly. On the way to orbit, the shuttle also uses two reusable solid rocket boosters (SRBs) which provide about 83% of the takeoff thrust. These use a solid fuel containing aluminum (the fuel), ammonium perchlorate (the oxidiser), iron oxide (a catalyst), and the mixture is held together with an epoxy and a binder (which also acts as fuel). While in space, the shuttle uses the reaction control system (RCS) thrusters which are seen on various places on the shuttle orbiter, and two orbital manoeuvering system (OMS) engines. The RCS and OMS use monomethyl hydrazine as the fuel and nitrogen tetroxide as the oxidiser.

Why is there a white triangle under the space shuttle engines when they are lit?

Why is there a white triangle under the space shuttle engines when they are lit? Within the flame produced by a lit space shuttle engine, there are temperature and pressure differences causing the flame to appear in different colors. The white triagle is made the by the shape of the space shuttle engine in combination with these temperature and pressure differences.

What is a space shuttle what does it do?

A space shuttle is a reusable launch and orbital spacecraft. It was designed by NASA for human space flight. The space shuttle takes humans into space. It also can be used to deploy satellites, probes, additions to the space station, and parts used to work on the space station. The space shuttle has also been used to conduct experiments in space.
