CACIQUE – Student-Developed Solid Rocket Motor

Singularity is a Costa Rican aerospace engineering team focused on the development of high-power rocketry and advanced aerospace technologies in Central America. Our team holds Level 2 High Power Rocketry certification from the Tripoli Rocketry Association and combines engineering design, simulation, manufacturing, testing, and system integration to transform ambitious concepts into functional aerospace hardware. Beyond our technical projects, we also organize educational workshops for schools, introducing students to rocketry, engineering, and aerospace technology with the goal of inspiring new generations to explore STEM fields. Through these initiatives, we aim to strengthen engineering and manufacturing capabilities in the region, promote aerospace innovation, and contribute to positioning Central America as an emerging participant in the global aerospace sector.

As part of this mission, CACIQUE is a high-power rocket developed by Singularity to compete in BAJA ROCKET 2026. The project brings together systems designed and manufactured by our team, including an experimental Class J solid rocket motor. A key part of its development is the production of precision metallic components for the propulsion system, where manufacturing quality and dimensional accuracy are essential for safe and reliable operation.

The following images show a preliminary design of our rocket and solid combustion motor.

Our propulsion system is a fully team-developed Class J solid rocket motor designed with a strong focus on performance, reliability, and safe operation. It uses a candy-based propellant and incorporates a converging-diverging nozzle to efficiently accelerate combustion gases and generate the thrust required for CACIQUE’s flight. Structurally, the motor integrates a metallic casing, precision-machined nozzle and end closure, sealing elements, grain inhibitors, and internal components designed to promote controlled combustion, with its design supported by ballistic modeling, previous static-test data, and structural calculations that evaluate the main pressure-induced and mechanical loads while maintaining appropriate safety margins.

Our main propulsion system components include a precision-machined steel nozzle, along with an aluminum motor casing and end closure. The holes shown in the design are intended for retaining bolts, which secure the nozzle and end closure in place even under the high pressures generated inside the combustion chamber. The following images show these key components of the motor design.
