ALDEBARAN: A "SYSTEM" DEMONSTRATOR PROJECT FOR NEW GENERATIONS OF SPACE TRANSPORTATION, NOW ENTERING IN THE PHASE A.
Aldebaran is the name chosen for a "system" demonstrator project which paves the way for one or more
next-generation launch vehicle targets.
The proposed demonstrator comes at a time when it is planned to operate existing European launch
vehicles (ARIANE 5, Soyuz, VEGA) until around 2025, with in parallel preparations activities for the
development of a new generation launcher. The project is aiming at developing a flight demonstrator by
focusing certain activities involved in the preparation of future launch vehicles. The first launch may take
place around 2015. It would represent a major contribution to the development of a new-generation
launch vehicle.
Several Aldebaran concepts have already been analysed in the “phase 0” during 2008. A selection process
have been applied taking into account the benefit of the proposed new technologies for the future launch
systems, but also the interest of the partners for instance by taking advantage of research activities already
foreseen. An other important selection criteria was the global development cost until the first
technological flight. The result of this “phase 0” selection process will be explained.
Three concepts have been retained for the “phase A”:
- An airborne solution launched from a military aircraft which will allow to build a dual stages
expendable “system” demonstrator, involving the main technological innovations in the frame of the solid
propulsion (first stage with new propellants), the liquid propulsion (upper stage with methane), the
structures and materials, the avionics and more globally: the “system” activities. The work foreseen in
phase A will not only focus on general studies for system and propulsion, but it will also concentrate on
some first technological sub-system demonstration tests.
- As a first alternative, an airdropped concept, launched from a cargo aircraft, is kept. It will mainly
be studied regarding safety and operational aspects in addition with the “extraction” phase when the
demonstrator is airdropped from the cargo bay, and has to be ignited at a safe distance from the aircraft.
The technologies involved in this concept are identical to the previous ones.
- As a second alternative, a “more conventional” vertical ground lift-off type of expendable solution
is retained. The idea is to push as far as possible the technological choices for a “very low cost” launch
system, the propellant choices remaining “open”. As for the airborne solution, general studies and subsystem
demonstration tests will be addressed during the phase A.
The paper will present the result of the “phase 0” concepts selection process held in 2008. And it will
show some of the first technological choices and demonstrations envisaged for the phase A of Aldebaran
