What is a common risk when using dual-deployment rockets with a drogue and a main parachute?

When utilizing dual-deployment rockets, the primary concern is the proper arrangement and deployment sequence of the drogue and main parachutes. The use of both parachutes provides a controlled descent and helps reduce landing speed, but it also introduces a risk of tangling if the parachutes are not configured correctly. If both the drogue and the main parachute deploy in a way that their cords become intertwined, it can result in a compromised descent, potentially leading to an unstable landing or even damage to the rocket.

Ensuring that the parachute deployment sequence and the lines are correctly set up prior to flight is crucial to avoid this entanglement. This risk emphasizes the importance of thorough pre-launch checks and understanding the mechanics of dual-deployment systems in rocketry. Properly managing and understanding the deployment sequence can greatly enhance the safety and effectiveness of the recovery system.
