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.

UAH Solid Propellant Characterization

43rd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2007
One of the main properties of solid propellants that must be known before a solid propellant design can be implemented into any use is the burning rate law. The objective of this works is to investigate the temperature sensitivity as a function of pressure for a composite propellant.

Ignition and Combustion of Solid Propellants

1961
Abstract : A model for the ignition response of solid propellants is presented, which predicts ignition behavior with respect to pressure and surface heat flux in qualitative agreement with experimental measurements. Surface regression is treated and a steady-state burning model is employed, which assumes equlibrium vaporization at the surface and a ...

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.

Solid Propellant Aging Kinetics

45th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2009
Accelerated aging was used to estimate how solid propellant mechanical properties change over periods spanning many years. Propellant was obtained from dissection of a rocket motor that was removed from a deployed inventory. This unit was about nine years old when tested.

Solid Propellant Environmental Issues

Waste Management, 1998
The objective of the Solid Propellant Environmental Issues (SPEI) project is to demonstrate environmentally acceptable technologies that will enhance the continued production of solid rocket motors (SRMs) by complying with current and anticipated environmental regulations.

Solid ADN Propellant Development

49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013
Ammonium dinitramide, ADN, is studied in Sweden in order to develop castable high performance minimum-smoke propellants for tactical missile applications. In 2010, 3 kg grains based on 70% ADN and 30% GAP were cast and test fired successfully. This paper presents on-going work at FOI concerning ADN propellant development which includes upscaling the ...

Ignition of solid propellants

Journal of Applied Mechanics and Technical Physics, 1972
At present, the study of solid-propellant ignition is of particular interest owing to the adoption of hybrid motors [1–3]. The status of experimental and theoretical research in this field can be evaluated on the basis of the rather extensive survey of American papers in [2].

Solid Propellant Reclamation Study

1982
Abstract : Alternate methods for the disposal of solid propellants were identified and evaluated, including laboratory tests. The methods included (a) alternate use or application, (b) relamation of major ingredients, and (c) incineration. A pilot plant design was provided and an economic analysis of alternate disposal methods conducted.
