Nil, Ariane Group: Launcher Electrical System: A Generalized Functional Description of the Ariane Launcher’s Avionics

ABSTRACT
A6 Launcher System Avionic

Ariane 6, A Versatile Launcher: launches of any mass, to any orbit, at any time.
A6 is the next-generation launch vehicle and will be built in two versions: Ariane 62 and Ariane 64. With this modularity and the according performances, Ariane 6 will cover a wide range of missions: GEO, through intermediate orbits (in particular GTO and GTO+), Polar/SSO, MEO and others. Ariane 6 is able to carry any type of spacecraft, from the smallest (1.000 kg or less) to the largest (>20.000 kg), in either dedicated or shared launch.
The flight is performed automated, that means there is no steering and controlling of the launcher after its lift-off from the ground. In order to do so, the control is taken over by the on-board computer having the control of the sub-systems necessary to steer and initiate the separation of parts of the launcher until the release of the payloads into the appropriate orbit in space from the upper composite of the launcher.

One Key Element is the Ariane Avionics, the Electrical System and Software

• This presentation will give an introduction to the composition of the Ariane 6 rocket and its main subsystems. It will specifically focus on the upper liquid propulsion module (ULPM) of the launcher which is the upper stage of the launcher.
• It will present how the avionics are modularized according their purposes, how they are interacting with each other during the different flight phases as well as the principles to ensure its and people’s safety.
• This presentation provides a generalized view on the launcher avionics to the required main modules, i.e. it provides a global description of the main avionics functions. They do not correspond to A6 avionics denotations except for examples.
