In high-power rocketry, the recovery subsystem represents one of the most critical components. Pyrotechnic systems are among the most commonly used methods in this field due to their simplicity and performance; however, they present limitations in higher-altitude flights, where their effectiveness can begin to decrease. In response to this challenge, the recovery team of the Costa Rican Aerospace Team for Experimental Rocketry has developed a pressurized CO₂ ejection mechanism, enabling a controlled release that may help mitigate the limitations associated with other commonly used methods.

The system has been designed and manufactured by team students, primarily using machined aluminum components, and is intended for a dual-deployment recovery system. The first event will occur at apogee, followed by the activation of the second system at 400 meters above ground level. Thus, two mechanisms will be integrated and activated independently. Activation is performed using an e-match, which generates the energy required to drive a pin that punctures the cartridge and releases the pressurized gas in a controlled axial manner.

The system is currently undergoing validation and flight integration, supported by ground tests focused on ejection and airframe separation. As part of this methodology, its implementation as the recovery system for the Miravalles rocket is proposed. This vehicle is over two meters in length and has an estimated apogee of 1 km. Two parachutes manufactured by the team will be deployed, with the objective of evaluating the system's performance under real operating conditions and collecting data for future optimization.

Through this development, the team aims to demonstrate the potential of CO₂ as a safer and more efficient alternative for recovery systems in experimental rocketry.
