What is it about?
This paper describes a cost-effective and modular longeron-stringer design to resist structural loads for the University of California San Diego's SEDS chapter's high-altitude rocket, Halya. The unified design for the primary structure of the rocket enables fast iteration cycles, ideal for collegiate teams with high turnaround. Conservative, low-computation simulation provides estimates for failure loads which were experimentally validated via strain gauges.

Why is it important?
The low-budget, high-turnaround, and high-speed nature of collegiate rocketry means standard industry practices for structural design are not practical at college levels. The paper evaluates a method of shortening the time needed to fabricate and evaluate new designs, which can be mimicked by other collegiate teams that face similar challenges.
