  • Propulsion

    Propulsion

    We selected this motor to complete our mission and reach an altitude of over 10,000fts. Initially, I planned to use an M1845NT Motor, but after simulating it in OpenRocket with the expected weight, it didn’t reach the target altitude. Therefore, I decided to use this motor with a higher average thrust. Area specific Propulsion Type…

  • Payload

    Payload

    The payload in this project adheres to the 3U CubeSAT standard and includes three advanced IMU sensors (10-DoF MEMS IMU sensor [SEN0140], 9DOF IMU AHRS sensor module, and 9-axis IMU LSM9DS1 module) to measure vibration, acceleration, and angular velocity, aiming to validate sensor durability and vibration resistance under launch conditions, comparing data over altitude and…

  • Recovery

    Recovery

    In our recovery system, the drogue parachute is deployed at apogee. The secondary charge is activated 1 second after apogee. The main parachute is deployed at an altitude of 1,000 feet, and its secondary charge is also triggered 1 second after reaching that altitude. The parachute diameters are 2.3 feet for the drogue and 7.22…
