Abstract
The invention relates to a multistage launch vehicle and method of multistage launch vehicle operation in which at least one subsequent motor stage is ignited following lift-off in partially overlapping relationship with its immediately preceding motor stage prior to shut-down and staging of the preceding motor stage in order to effect positive thrust control over the launch vehicle throughout shut-down and staging of the preceding motor stage. Preferably, each of the motors comprising the subsequently fired motor stage is provided with a thrust profile in which maximum thrust is attained prior to staging of the preceding stage.
