The D-SEND project is composed of drop tests D-SEND #1 and D-SEND #2. In the D-SEND #1 drop test, two different axisymmetric bodies are dropped from an aerial blimp and the sonic booms are measured and compared with each other.
In the D-SEND #2 drop test, an experimental supersonic airplane (unmanned aircraft with no engine and capable of autonomous flight) designed utilizing JAXA's proprietary low sonic boom design technology is dropped and the sonic boom is measured. The sonic booms are measured and recorded by the microphone system that has been set up in a line between the ground and the blimp (altitude of 1km).
These drop tests will take place at the Esrange Test Site near Kiruna in Sweden.
