    The solid rocket motor is one of two major classes of motors, where liquid propellant is the other kind. What makes solid unique versus the liquid propel-lant, is the simplicity of the motor. The solid propellant contains the fuel and oxidizer. It is therefore enough to ignite the propellant and no other chemical

    In the air augmented rocket, air is collected by an intake surrounding the rocket body, and used to augment the rocket exhaust. Air/Slush LH2 Air/Slush LH2 propellant. In this propellant scheme, ambient air (78 % nitrogen, 21% oxygen, etc.) is scooped up by air intakes and used in turbojet, turbofan, ramjet, scramjet, or other airbreathing engines as an oxidizer.

    How a Solid Propellant Rocket Works - thoughtco

    Once a solid rocket is ignited it will consume the entirety of its fuel, without any option for shutoff or thrust adjustment. The Saturn V moon rocket used nearly 8 million pounds of thrust that would not have been feasible with the use of solid propellant, requiring a high specific impulse liquid propellant.

    Conceptually, solid rocket motors (or SRMs) are simple devices with very few moving parts. An electrical signal is sent to the igniter which creates hot gases which ignite the main propellant grain (see image below). The propellant contains both fuel and oxidizer; therefore these devices can operate in the vaccuum of space.

    Jun 12, 2014· In a solid rocket, the fuel and oxidizer are mixed together into a solid propellant which is packed into a solid cylinder. A hole through the cylinder serves as a combustion chamber . When the mixture is ignited, combustion takes place on the surface of the propellant. A flame front is generated which burns into the mixture.

    Rocket propellant is the material used by a rocket engine to generate thrust. The most common propellants consist of a fuel and an oxidizer that participate in chemical reactions to produce extremely hot gases. These gases exert pressure that propels the rocket forward while they are ejected in the form of a jet through the rear.
