What type of recovery device can deploy at multiple altitudes?

A dual deployment recovery system is designed to deploy at multiple altitudes during a rocket's descent phase. This system typically utilizes two parachutes: a small drogue parachute is deployed at a higher altitude to slow down the rocket, followed by the deployment of a larger main parachute at a lower altitude for a gentle landing. The use of dual deployment effectively manages the rocket’s descent speed and helps to stabilize it, reducing the chances of damage upon landing.

This system is beneficial for high-power rocketry, where maintaining control and ensuring safe recovery is critical. The ability to deploy parachutes at specific altitudes enhances the recovery performance, allowing for a controlled descent rather than relying on a single parachute that may not effectively manage the descent rate if deployed too late or too early.

In contrast, a single-chute system does not have this capability as it deploys only one parachute, limiting altitude management. A sequential recovery device typically involves deploying recovery devices in a predetermined sequence, but may not specifically refer to multiple altitude deployments. A standard drop chute is designed for a straightforward drop and does not allow for multiple deployments at varying altitudes. Thus, the dual deployment recovery system is the only option that ensures versatility through its ability to deploy at different altitudes
