Abstract Solid rocket motors have been the mainstay of ISRO's sounding rockets and the first generation satellite launch vehicles. For the new launch vehicle under development also, the solid rocket motors contribute significantly to the vehicle's total propulsive power. The rocket motors in use and under development have been developed for a variety

Journal of the Royal Aeronautical Society, 1962
The relative merits and possible applications of liquid and solid propellant rocket motors have long been topics for discussion and controversy. The arguments for and against have been sharpened by the fact that the development of the two types of motor are usually vested in quite different teams of people. At the same time, a fair comparison has often

Aircraft Engineering and Aerospace Technology, 1947
THE rocket motor is a form of jet propulsion which is characterized by independence of the external atmosphere for combustion, relative independence of altitude and flight velocity upon thrust, small frontal area for high thrusts, simple construction and low weight, and high rate of fuel consumption.

25th Joint Propulsion Conference, 1989
The Advanced Solid Rocket Motor (ASRM), a 150-in diameter segmented motor design that incorporates substantive design changes to improve the reliability and design safety margins of the Space Shuttle system, is discussed. The studies involved in the development of the ASRM are reviewed, and the ASRM design is summarized, including safety enhancement ...

Liquid Propellant Rocket Motors
The Journal of the Royal Aeronautical Society, 1953It 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,

Rocket Motor Instability Studies
Journal of Jet Propulsion, 1955I two previous papers (1, 2), experimental data relating to the problems of combustion instability in 3-in. diam rocket motors were presented. Two types of axial oscillations were identified: (a) A low frequency type of instability (220-360 cps) which is distinguished by abrupt and severe variations in radiation intensity, (b) A high frequency type of ...

Solid Rocket Motor Optimization
44th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2008A preliminary design of a solid rocket motor (SRM) is based on a multitude of design parameters (e.g., thrust profile, chamber pressure, burn time, etc.), whose values are difficult to determine initially, necessitating the design modeling and optimization for the specific mission.

Solid Propellant Rocket Motors
The Journal of the Royal Aeronautical Society, 1961A 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.

Additional historical solid rocket motor burns
Acta Astronautica, 2006Abstract The use of orbital solid rocket motors (SRM) is responsible for the release of a high number of slag and Al2O3 dust particles which contribute to the space debris environment. This contribution has been modeled for the ESA space debris model MASTER (Meteoroid and Space Debris Terrestrial Environment Reference).
