Trajectory - A Rocket Portfolio


A little about me… 😎

Welcome to my model rocketry portfolio!

This repository showcases my journey designing, building, and launching model rockets. You'll find CAD models, 3D-printed parts, analysis, and code for each project.

I'm Connor, a high school student using rocketry to build engineering foundations. Based in the Bay Area, I'm a NAR member with three years and ~20 launches of experience. I participate in launches at Hollister and Snow Ranch when possible. My current goal: earning my Level 1 certification for higher-impulse motors.

Beyond rocketry, I have two other passions:

Varsity Robotics

I'm on my high school's varsity robotics team, specializing in mechanical design. We compete in the FIRST Robotics Competition (FTC), building competition robots under tight deadlines. My focus areas:

  • Creating efficient drive systems with CAD and 3D printing
  • Fabricating custom parts and complex mechanisms
  • Developing mechanical subsystems for specific challenges

Mountain & Road Biking

When not building, I'm like to go biking in the South Bay:

  • Mount Umunhum: 9.5 miles, 3,500+ feet elevation, spectacular views
  • Mount Hamilton: 18-mile climb to Lick Observatory
  • Off-road trails: fun downhills and challenging terrain

Cycling provides a good way for me to get exercise and clear my mind

My current flagship rocket is the Crimson Dragon - details in the projects section below.

About this repository:
β€’ Introduction to who I am, what I've built, and my goals
β€’ Organized by project stages with overview documents under /proj
β€’ Written to be beginner-friendly, though some technical terms are included

Hi! I’m Kaeden

I’m Kaeden. I’m also a high school sophomore, and I’m interested in using engineering to create meaningful projects. I love using CAD models to create 3D-printed objects that I can use in my personal projects.

Robotics Engineering

I’ve taken a range of courses in engineering and robotics engineering, and I’m excited to keep building on that foundation through hands-on, real-world projects. My goal is to integrate thoughtful design with practical building to create solutions that make a positive impact in my community.

After Hours

I love to stay active and keep a consistent routine. It helps me stay focused, manage stress, and bring more energy into school and engineering projects.

  • Competitive tennis (training + matches)
  • Runs for endurance and recovery (also to unwind from a rough day)
  • Working out to build strength

CFD Screenshots Into Repo Rocketry Upload updated CFD simulations and diagrams into the repo and future Notion page since any more projects have not been uploaded since
Upload Specific Designs Rocketry In proj, make uploads about the individual versions of each designed parts, as well as failure analysis if applicable. (From CAD software as well)
Change Explanation Rocketry Explain the differences and upgrades between each iteration of part/project
Update Roadmap Rocketry Refresh the repo roadmap to be up to date on all of the events that are happening while rocket is not being built
3D Print with Raspberry Pi Engineering Be able to link the 3D printer to a remote USB to have the ability to 3d print remotely
