Mechanism of dynamic instability in lift-type reentry capsule at supersonic flow

What is it about?

Numerical simulation was conducted to investigate mechanism of dynamic instability, which is the self-excited oscillation in lift-type reentry capsule at supersonic flow.

Why is it important?

If the dynamic instability occurs during parachute deployment, the mission failure can be induced directly. Therefore, elucidation of its mechanism and establishment of a stable capsule shape are quite important.
