  • 1 Improved Mach number capability of S2MA

    The Mach number test envelope of the ONERA S2MA transonic and supersonic wind tunnel will soon be continuous up to Mach number 3 1. The gap which was existing until now, between Mach number 1 3 and Mach number 1 5 will be filled. The definitive implementation of the tunnel modifications, and the associated validation tests over the complete Mach number range of the wind tunnel have been done during the first semester of 2016
  • 2 New Mach number regulation system for S1MA - FP7

    The new Mach number regulation at S1MA, sponsored by the European FP7 ESWIRP project, implements two complementary regulation components... A very precise identification of the various transfer functions affecting the Mach number drift has been established... The Mach number drifts in polar process have consequently been drastically reduced
