Abstract
Disclosed herein are various technologies pertinent to jettisonable battery systems for use in rocket engine-based launch vehicles. Such systems may feature battery units that are configured to be used to power one or more electric turbopumps that may be used to supply fuel to a rocket engine or engines. One or more of the battery units may be jettisoned during flight in order to reduce weight and as they are depleted. In some implementations, the battery units may be connected in parallel with the turbopump(s), with a depleted battery unit being electrically disconnected from the parallel circuit and jettisoned.
