The grain consists of a fuel and an oxidizer in solid form. It is shaped like a cylinder with one or more channels or ports that run through it. The ports increase the surface area of the grain that the rocket burns. Unlike some liquid propellants, the fuel and oxidizer of a solid-propellant rocket do not burn upon contact with each other. Instead, an electric charge ignites a smaller grain. Hot exhaust gases from this grain ignite the main propellant surface. ]]> 2018-01-12 19:37:03 UTC https://padlet.com/jerry_mwamba/sql5clzoob45/wish/221108940
