Flight Demonstration of Pulse Detonation Engine Using Sounding Rocket S-520-31 in Space

What is it about?

A detonation engine system is successfully demonstrated for the first time in space using sounding rocket S-520-31 of the Japan Aerospace Exploration Agency/Institute of Space Astronautical Science. The flight is conducted to confirm that the pulse detonation engine (PDE) and its system operate at scheduled sequences in space, confirm the reproducibility of the PDE cycle, and despin the rocket around its axis.
