Objectives

The MPBus Project is committed to develop a new power bus architecture combining ejectable batteries with the main bus through intelligent nodes. These nodes are able to communicate between them and a battery controller using an improved, data BUS over DC line technology, expected to reduce the total weight in two main areas:

 

  • Improving the use of the batteries The use of a new battery management concept will allow reducing the battery weight of the launcher after each stage, because the depleted batteries will be ejected with its correspondent stage.

 

  • Reducing the total weight due to harness Once a battery management data over DC bus has been developed, this same bus can be used for non-critical data recording.

 

The structure is based on a modular three-stage launcher like Ariane 5 and other launchers with similar characteristics, with the batteries distributed along the different stages.
