http://www.spaceportrocketry.org/Dual-Event%20Recovery.html WebA multistage rocket is one that uses two or more engines that ignite consecutively (one after another) to propel a rocket higher and faster. Lower and intermediate stages always use engines that have no delay or tracking smoke and no recovery system ejection charge. The absence of a delay charge allows the next engine to receive the maximum ...

Lower and intermediate stages always use … A two-stage-to-orbit (TSTO) or two-stage rocket launch vehicle is a spacecraft in which two distinct stages provide propulsion consecutively in order to achieve orbital velocity. It is intermediate between a three-stage-to-orbit launcher and a hypothetical single-stage-to-orbit (SSTO) launcher. At liftoff the first stage is responsible for accelerating the vehicle.
