N2 = Nitrogen N2O = Nitrous Oxide

Increasingly military and commercial system applications seek smaller and smaller packaging. This in turn has a corresponding demand on energy and power requirements. This paper examines the available technologies which can be used to produce propulsion. The available technologies are examined using the criteria of: short duration power missions, millipound class and smaller thrust levels, performance and toxicity. It will be shown that for space, air, ground and sea applications monopropellant hydrogen peroxide based propulsion in general terms provides the best overall solution
