Objectives
The project is to develop two large variants of the mechanical platform of the EADS Astrium Eurostar 3000 telecommunications spacecraft, designated as E3000LX and E3000L. The aim of the programme is enable the Eurostar 3000 family to serve markets in the larger and heavier spacecraft sector.
The development will include all tasks necessary to create fully designed and qualified products ready for immediate application to flight programmes. A significant element of the development is the design and qualification of an improved bonded joint for the central cone / cylinder capable.
Two variants will be developed:-
- E3000 LX will have a maximum launch capability of 6400Kg and incorporate a Chemical Propulsion System combined with a Plasma Propulsion System to extend the on station life.
- E3000 L variant will have a launch mass of 6200Kg with extended tanks for the Chemical Propulsion System.
Challenges
The major challenges and key issues in this project:
- To design a ring to panel joint which would be simpler to assemble, have higher load capability and improved resistance to damage at cold temperatures.
- The design of two new E3000 variants which would benefit from improved performance and extend the product range up to 6.4 tonnes, while maintaining commonality of components and production techniques and giving due regard to mass.
- To ensure that the joint design could be implemented on to the current E3000 range without disrupting the production activities or compromising quality and reliability.
Current Status
The project has been successfully completed and orders have been awarded for both the E3000L and E3000LX variants.
