CNES / ONERA EOLE
Design and production of a sub-scale demonstrator of a first stage innovative rocket
Program developed by the CNES ( National Center for Space Studies ) in cooperation with ONERA ( National Office for Aerospace Studies and Research ) in the fields of the Perseus project ( www.perseus.fr ).
Objectives: Design and produce a sub-scale demonstrator of a full scale aircraft that can carry and launch a fully instrumented powered rocket at high altitude.
This drone shall be used as a modular test bench for the following purposes :
- Verification of the rocket separation;
- Verification and live test of different aerodynamic configurations;
- Possibility to load up scientific experiment modules;
- Shall be similar in inertia, relative mass and relative speed to the full scale aircraft.
Eole will be fitted with an auto pilot system including GPS navigation capability and a ground pilot station.
It is equipped the an on-board video system capable of capturing sequences of the launch phase.
EOLE has been CAD designed and drawn by Aviation Design in collaboration with the ONERA and is patented.
