D-SEND#1 Overview



JAXA conducted the D-SEND#1 drop tests on May 7th and 16th in 2011 at Esrange test range in Sweden supported by the Swedish Space Corporation(SSC). The low sonic-boom design results have been validated with an axisymmetric body for the first time.

The D-SEND Database provides the geometries of two D-SEND#1 models named NWM(N-wave Model) and LBM(Low-Boom Model) as well as these drop profile data and sonic boom data obtained in both drop tests.
