Once ignited, a simple solid rocket motor cannot be shut off, because it contains all the ingredients necessary for combustion within the chamber that they are burned in. More advanced solid rocket motors can not only be throttled but can be extinguished and then re-ignited by controlling the ...
the subject of the invention is a way to produce the heterogeneous, rocket fuel, whose main ingredients are: an oxidizer - ammonium chlorate (vii),powder aluminium (aluminum) and a binder based on cieklego terpolymer of butadiene, acrylonitrile and methacrylic acid.the essence of the invention ...
It was this thought experiment that has motivated [Thoisoi2] to experiment with making a rocket motor using only ingredients and methods available to your average Martian colonist.The methods he has chosen can be seen in the video below the break. If you skipped Rocketry 101, a quick refresher...
When standard ingredients are used (namely, AP/Al/HTPB or similar), solid propulsion is simple, reliable, relatively low-cost. High energy density grants lower volumes with respect to hybrid and liquid rockets so it is convenient for on-board compact applications (inertial upper stages, ...
Black powder technically should not be called gunpowder because its use in rockets preceded that in guns. The ingredients are charcoal, sulfur, and saltpeter (potassium nitrate). These three ingredients were known in China for many centuries, however, before they were combined into black powder. ...

Proper bonding of EHSM to composite propellant is critical for solid rocket motor performance. Composite propellant is usually prepared with HTPB as a binder for oxidizer ammonium perchlorate particles and other ingredients. From this point of view, PU–EHSM is better as insulation materials because ...
