Boba Launcher — Version 2 (Theoretical Design)
CAD Design
Detailed CAD design exploring pressure chamber geometry, sealing mechanisms, and projectile guidance. Designed purely as a theoretical exercise due to the legal constraints of Canada.
ANSYS Simulation
Structural and pressure simulations performed in ANSYS to validate chamber integrity and stress concentrations under theoretical operating pressures.
Putty Launcher — Version 1
Adiabatic Calculations
Derived closed-form energy and pressure relationships using adiabatic expansion models to predict muzzle velocity and chamber efficiency, then validated calculations using an experimental setup.

CAD + Simulation
Modeled full assembly and validated mechanical integrity under operating loads. Iterated on barrel geometry and chamber size to improve consistency and reliability.
Final Product Showcase
Fully functional launcher capable of repeatable launches of 15 gram putty slugs at 50m/s muzzle velocity given a maximum pressure of 50psi. Optimized valve timing, pressure control, and projectile-tube fitting for reliable operation; launches were done on secured private property in Hong Kong as to alleviate legal concerns.
