"Halya is a supersonic-sounding rocket designed to break height, speed, and acceleration records in collegiate liquid rocketry. The rocket will compete in the FAR MARS launch challenge, where it will fly to 45,000 ft and recover with a parachute. During its 5-minute flight, it will experience a maximum of 17 G’s of acceleration and reach a top speed of Mach 2 in 4.6 seconds. The Halya team is using advanced manufacturing techniques such as composite layups and metal 3d printing to make Halya as structurally strong and light as possible in order to achieve these performance goals." -From SEDS at UCSD

Devin specializes in designing propellant feed systems and is currently serving as both the Propellant Feed Lead and overall Project Manager. He's the primary contributor to designing the entire rocket's propellant feed system including component selection, pressure and flowrate requirements, plumbing layout, and piping and instrumentation diagram creation. He is also developing custom-made manifolds to be either metal 3D printed or manufactured at UCSD's student machine shops.

Since Halya is still in development and contains designs from SEDS at UCSD, more detailed images regarding the current status cannot be shared on this portfolio. CAD images may be out of date, incorrect, and not representative of Halya's actual design and are there for illustrative purposes only.

Devin and his team on the Halya Methane Rocket are refurbishing Vulcan II while also concurrently developing Halya. Vulcan II is a Liquid Oxygen and Kerosene powered rocket designed to fly to 20,000 ft. It was designed back in 2017 and has been delayed to launch due to COVID-19. 

Vulcan II had two launch attempts during the summer of 2021 but both failed for various reasons. As a result, it was decided that Vulcan II would fall into the hands of Halya. The team is working on refurbishing Vulcan II after an ignition failure and preparing Vulcan II for a static fire, where the rocket is held down and the engine is fired to simulate a launch.

The team has to reconstruct parts of Vulcan II that were damaged or destroyed during previous launch attempts. They also have to redesign certain systems to make Vulcan II safe to static fire.

Devin is working on deconstructing, cleaning, and reassembling the propellant feed system on the rocket. He and the team completed a full cold-flow test of the rocket in Fall 2021 and a water flow test in Winter 2022 where Devin served as the Test Director for both tests.

Devin also serves as an additive manufacturing technician, printing many of the 3D printed parts including but not limited to the fins, mounting brackets, and structural connectors.
