1. Project Overview
• Leader of the project
• Designed, assembled, and tested each
system of rocket
• Developed reusable KNSB solid rocket
engine
• Established 1-D mathematical model of
rocket motion
• Developed wireless ignition system
(based on Arduino and RF module)
• Recovered video data

2. Rocket Engine
• KNSB Fuel
• Reusable and Reliable
• Cheap and easy to maintain
The thermal conductivity of 304 stainless steel is too low.
This will cause heat around the nozzle cannot dissipate in
time, causing overheat in this particular area, decreasing the
structural rigidity and causing danger. So we use 45 steel in
these places.

3. Rocket Engine
• Used ANSYS to
evaluate nozzle design

4. Rocket Engine
• Used strain gauge to
collect thrust data

5. Rocket Engine
• Used MATLAB and
Simulink to establish
mathematical model
of rocket engine

6. Rocket Structure
Necessary components were 3d modeled and
manufactured by 3D printing with PLA material.

7. Avionics
Altitude Record Module
Parachute Release Module Power Module
On Board Camera

8. Rocket Structure

9. 1-D Mathematical Modeling

10. Fairing and Parachute
Release System
Parachute cabin will separate
when the rocket's depression
angle is more than 10 degrees.

11. Ignition System

12. Launch

13. Data Recovery
