Numerical Analysis of Solid Rocket Motor Instabilities With AP Composite Propellants [PDF]

open access: yes, 1999
A non-steady model for the combustion of ammonium perchlorate composite propellants has been developed in order to be incorporated into a comprehensive gasdynamics model of solid rocket motor flow fields.

Advances in phase stabilization techniques of AN using KDN and other chemical compounds for preparing green oxidizers

open access: yesDefence Technology, 2019
Research and development of green oxidizers and green fuels as a possible replacement for ammonium perchlorate (NH4ClO4, AP) and hydrazine (N2H4) respectively has been increased considerably in the recent years. AP and hydrazine are the oxidizer and fuel

Numerical Study on Response Characteristics of Solid Rocket Pintle Motor [PDF]

open access: yesJournal of Aerospace Technology and Management, 2019
Pintle technology is currently a versatile technology used in a solid rocket motor (SRM) to control the desired thrust by changing the nozzle throat area, while effectively controlling the chamber pressure at the same time.

A miniature solid propellant rocket motor [PDF]

open access: yes33rd Joint Propulsion Conference and Exhibit, 1997
A miniature solid-propellant rocket motor has been developed to impart a specific motion to an object deployed in space. This rocket motor effectively eliminated the need for a cold-gas thruster system or mechanical spin-up system. A low-energy igniter, an XMC4397, employing a semiconductor bridge was used to ignite the rocket motor.

Thrust termination of solid rocket motor

open access: yesJournal of Physics: Conference Series, 2022
Abstract Rocket motors are engines that create the necessary thrust for the rocket motion. There are different types of rocket motors based on the propellant state, such as solid propellant rocket motors, liquid propellant rocket motors, and hybrid propellant rocket motors.

Anomalous Behavior of a Solid Rocket Motor Nozzle Insert During Static Firing Test

open access: yesJournal of Aerospace Technology and Management, 2016
This paper presents the study and development of a firing test used to evaluate the behavior of a solid rocket motor. The motivation for the development of a subscale solid rocket motor with end burning propellant grain geometry arose from the need to ...
