Editing Solid-propellant rocket (section)

===Electric solid propellants===
Electric solid propellants (ESPs) are a family of high performance [[plastisol]] solid propellants that can be ignited and throttled by the application of electric current. Unlike conventional rocket motor propellants that are difficult to control and extinguish, ESPs can be ignited reliably at precise intervals and durations. It requires no moving parts and the propellant is insensitive to flames or electrical sparks.<ref>{{cite book|chapter-url=http://arc.aiaa.org/doi/abs/10.2514/6.2013-4168|chapter=Electrical Solid Propellants: A Safe, Micro to Macro Propulsion Technology|first1=Wayne N.|last1=Sawka|first2=Michael|last2=McPherson|title=49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference|date=12 July 2013|publisher=American Institute of Aeronautics and Astronautics|doi=10.2514/6.2013-4168|isbn=978-1-62410-222-6}}</ref>
