The selected bidder will become part of the industrial consortium for the Alphabus phase C/D and subsequent contracts related to the production of Alphabus based Telecommunication satellites.
In anticipation of the phase C/D contract a predevelopment contract will be placed by ESA directly to the selected bidder to cover the initial phase. As part of the proposal to the subject ITT the bidder will be requested to identify the predevelopment activities corresponding to this initial phase.
Companies interested in bidding for the above mentioned activity should declare their interest by 13 April 2004 to:
Mr X. Périllaud
Contracts Officer EADS Astrium
Telephone: + 33 (0)5 62 19 50 97

Purpose of the ITT: This activity is to develop a new type of propellant tank for satellite bi-propellant propulsion application. This tank shall be suitable for the Alphabus with respect to capacity, mass and performance. The development will include design, manufacturing and formal qualification program.
Since the Alphabus requirement is exceeding the currently manufactured tank sizes made by EADS for Spacebus and MAN for Eurostar by more than 50%, it is expected that the major technical challenges will be:
The hardware to be delivered is anticipated to comprise:
2 tank dummies for Satellite level mechanical validation purpose,
1 Flight set (2 tanks) for AlphaBus Proto-Flight Model.

The ITT will address the propellant tanks needed for Alphabus and include the following elements:
- “the development for the Alphabus product line,
- “the procurement of the protoflight model and
- “the long-term agreements for the Alphabus commercial phase

Summary Description
Purpose of the ITT: This activity is to develop a new type of propellant tank for satellite bi-propellant propulsion application. This tank shall be suitable for the Alphabus with respect to capacity, mass and performance. The development will include design, manufacturing and formal qualification program.
Since the Alphabus requirement is exceeding the currently manufactured tank sizes made by EADS for Spacebus and MAN for Eurostar by more than 50%, it is expected that the major technical challenges will be:
- spin forming of tank liner parts,
- joining of thin-wall liners,
- development of a large propellant management device (PMD) and integration in the liner,
- over-wrapping of closed tank liner with carbon filament forming of integrated tank fixation lugs as part of the over-wrapping
The hardware to be delivered is anticipated to comprise:
2 tank dummies for Satellite level mechanical validation purpose,
1 Flight set (2 tanks) for AlphaBus Proto-Flight Model.
