ROCKET PROPELLANTS

2023
            This chapter provides information on the definition, brief history, classification, essential properties, and new developments of rocket propellants. A rocket is just a chamber that holds pressurized gas. A narrow aperture located at one extremity of the chamber permits the gas to be released, generating a force that pushes the rocket in ...

Solid Propellant Rocket Motors

The Journal of the Royal Aeronautical Society, 1961
A solid propellant rocket motor consists essentially of a propellant charge in a container fitted with an expansion nozzle and igniter. Since, before a rocket motor can be designed, it is necessary to have some knowledge of the properties of the propellant to be used, a description will first be given of the propellants which are currently available.

Liquid Propellant Rocket Motors

The Journal of the Royal Aeronautical Society, 1953
It has been said that a rocket motor is the simplest “ prime mover.” This is correct in theory, since fundamentally a rocket consists of a chamber containing a gas under pressure, having a nozzle at one end through which the gas expands, forming a propulsive jet. Since the pressure ratio of the rocket is always greater than the critical pressure ratio,

Liquid Propellant Rocket Development

Journal of the American Rocket Society, 1946
Liquid Propellant Rocket Development" By M. W. NESBITT Chief Engineer, Reaction The subject of liquid propellant rocket development is one which has become greatly broadened in the past three years. In order to cover each phase of liquid rocket development in detail it would be necessary to spend considerably more time than is presently available ...

Solid Propellant Rockets

1968
Solid propellants are of two basic types: composites and double base propellants. The latter consist of a backbone of nitrocellulose (guncotton) onto which a quantity of nitroglycerine has been absorbed, resulting in a leathery propellant which can be cast or extruded into desired shapes.

Liquid-Propellant Rocket Engines

2012
The liquid-propellant rocket engine has the characteristics that allow it to deliver thrust at a high-performance level, with an efficiency and operational flexibility that enables a number of mission applications to go forward. Monopropellant and bipropellant versions of this category of engine are discussed in some detail in this chapter.

Solid-Propellant Rocket Motors

2012
The solid-propellant rocket motor brings the flight mission capability of high thrust delivery over a short duration. Design issues, such as tailoring the shape of the solid propellant grain (charge) to produce a desired thrust-time profile, are discussed in some detail in this chapter.
