GTD is conducting a study for CNES with the purpose of identifying the critical design factors of future command and control systems for Ariane 6, which would reduce recurrent maintenance and operation costs.Based on the knowledge gained through experience after more than 20 years of operation of the Ariane 5, VEGA and SOYUZ benches, and relying on its consolidated experience in systems design and development, GTD is proposing a number of areas for improvement for the new launcher that will allow maximizing the efficiency and effectiveness in maintenance and operation tasks.In this sense, proposals on the use of a reference architecture (based on a selection of technologies that enable long term maintenance) are presented, integrating operations into the control system itself and facilitating the qualification throughout the life cycle, not to mention the automation of operations.Ariane 6 elementsThe Ariane 6 is a three-stages configuration (called PPH) powered by solid propulsion for the lower composite (first two stages) and with a cryogenic liquid oxygen and hydrogen for the upper stage. For the lower composite, several options are being considered in terms of number, loading and arrangement of motors.For the upper stage, Ariane 6, similarly to Ariane 5 ME Adapted, will use cryogenic propulsion for the upper stage based on the Vinci engine. It will be restartable and have direct deorbiting features. Ariane 6 work logicThe preparatory work has begun, with a first phase of trade-offs between different PPH concepts that will lead to the selection of one Ariane 6 concept by the second quarter of 2013. Analysis will begin on the selected concept during the feasibility stage, planned for completion in mid-2013.This will be followed by the preliminary definition phase which aims to show the overarching objective of the Ariane 6 launch system can be met: reduced exploitation costs.The complete development of the Ariane 6 launch system will be proposed at the 2014 Council at ministerial level.
