Hypergolicrocketfuels spontaneously ignite when their two components come into contact with each other. While the fuel is difficult to handle, the hypergolic engine is easy to control and very reliable. A Redstone rocket, part of the Mercury program A rocket is a vehicle, missile or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust gas from within a rocket engine. ... For the workstation, see SGI Fuel. ... Ignition occurs when the heat produced by a reaction becomes sufficient to sustain the reaction, whether it be a fire, an explosion, or nuclear fusion. ...
The engine can be precisely controlled with only two valves, one for each fuel component. This simplifies the control system and eliminates points of failure. With no complex starting procedure the thrust is predictable i.e. the direction and velocity of the rocket will closely match calculations.
Hypergolic fuels have been used for intercontinental ballistic missiles, especially the Titan II missile, but because of difficulties in storing fuel, the trend in ICBMs has been to move toward solid fuel boosters. A Minuteman III missile after a test launch. ... Titan II launch vehicle launching Gemini 11 (Sept. ... The Space Shuttle Columbia is initially launched with the help of solid-fuel boosters Solid rockets are rockets with a motor that uses solid propellants (fuel/oxidizer). ...
They are less likely to explode when starting. This is called a "hard start." A rocketry term refering to an explosion of fuel. ...
