If there is a question of a wind instrument in the Sacso project, it is not a matter of music but of flightmechanics and aerodynamics... The model's flightmechanics parameters (positions, velocities, accelerations) are reconstructed from data internal to the model (acceleration and speed of rotation measurements), optical flight path tracking and model attitudes, the cable lengths
ONERA's expertise in the understanding of complex phenomena in the fields of solid and liquid propulsion, aerodynamics, aerothermics, acoustics and flightmechanics is strong with the definition of launcher control laws. ONERA has more recently contributed to the preparation of the future Ariane 6, in an earlier PPH version ("Powder", "Powder" and" Hydrogen" propulsion)
