The Machnumber test envelope of the ONERA S2MA transonic and supersonic wind tunnel will soon be continuous up to Machnumber 3 1. The gap which was existing until now, between Machnumber 1 3 and Machnumber 1 5 will be filled. The definitive implementation of the tunnel modifications, and the associated validation tests over the complete Machnumber range of the wind tunnel have been done during the first semester of 2016
The new Machnumber 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 Machnumber drift has been established... The Machnumber drifts in polar process have consequently been drastically reduced
