During initial parachute deployment, there are interactions between the parachute and its trailing wake. As the parachute is deployed and the payload decelerates, the air is decelerated in the payload direction in the wake formed behind the parachutes. As the deceleration continues, the velocity of the wake may overtake the parachute and cause a partial or total collapse, This phenomenon is known as wake recontact. This paper presents, considering the effect of the added mass, the calculation results of the wake and parachute velocities and conditions under which the wake recontact may occur.
