One of the main projects I had the opportunity to lead for the 2025 IREC was the development of a 2U form-factor deployable payload vehicle that would land independently of the PAX 1 launch vehicle.
The payload vehicle's intended mission was to separate, deploy, and land separately from the rocket vehicle during the recovery phase at an altitude of 1,200 ft. This vehicle was equipped with a custom flight computer, aluminum structural frame, recovery mechanism, wireless arming capability and camera system. It resulted in a successful deployment despite a not-so-successful rocket launch.
The first challenge of this project was to create a custom, lightweight frame that all the hardware could be mounted on. After an initial design phase, aluminum was selected as the material of choice. These frames were laser-cut and assembled with M2.5 steel screws.

Custom plastic plates were designed and 3D printed to be mounted on the aluminum frame. These served to cover the electronics on the inside of the payload vehicle while providing some aesthetics. All plates were printed from PETG with a multi-colored 3D printer.
Shown above is a picture of the payload vehicle ready to be inserted into the rocket prior to flight. To handle separation from the rocket, a Tinder Rocketry Tender Descender was utilized. The Tender Descender connected the payload to the rocket with a tether, which would pull the payload out of its compartment. After a brief delay, a black powder charge would blow and separate the payload from the tether.
To detect a successful nose cone separation event, a light sensor was mounted next to the camera compartment cutout. When the sensor detected light above a certain threshold, this meant that the nose cone had separated and a successful deployment had occurred. This logic was used to determine when separation from the rocket should occur.
