CONCLUSIONS
For f < 2 kHz, SRS < 0.2 * f was reached in A5/EPS and in A5/ESC configurations
This represents a diminution of ~ 15 dB of HSS1 levels
Such levels are now close to what is obtained during ESC/EPC separation
Development was long :
plane plate tests : 2005
L576/VA222 (1st HSS3+ A5/ESC flight) : 26/04/2015
This system is valid for every kind of P/L and need not any specific damping tuning
Plane plate tests have allowed a good estimation of P/L I/F levels
