PROJECTS
Mach 10 Oblique Detonation Flight Experiment
Flight test of a standing oblique detonation wave engine (ODWE). Designed high pressure fluid feed system and instrumentation routing for the sounding rocket payload.
Regeneratively Cooled Liquid Bi-Propellant Rocket Engine
AlSi10Mg ethanol-nitrous regeneratively cooled rocket engine. Personal project designed for steady state cooling at a maximum thrust of 617 lbf.
Electric Longboard
Electric longboard with two 36v brushless motors. Features custom drive train and electronics housing. Fabricating motor mounts using stationary power tools and Metal Inert Gas (MIG) welding.
Liquid Bi-Propellant Competition Rocket
1,600 lbf competition rocket. Led the combustion system in combustor design, ignition, and thermal management. Responsibilities include validating engine contours and thrust curves, creating a breakaway ignitor, and fabricating ablative liners.
Cooling Channel Optimization for High Enthalpy Vitiator Nozzle
Cooling channel geometry optimizer for high enthalpy nozzles. Accounts for 2D thermal and mechanical stress's and solves for highest factor of safety across channel geometry, coolant mass flow rates, and pressures. Used for a Mach 5 vitiated wind tunnel nozzle.
High Power Rocketry
High power rocketry launch attempt and fabrication. Successfully obtained my Level-1 certification on a J-class motor with successful recovery and apogee of 2,100 ft. Fabricating my Level-2 attempt.
Woodworking and Welding
Various projects including woodworking and welding.
