Project Overview
SpaceShot is the Princeton Rocketry Team's return to a mission to develop a cost-effective rocket capable of reaching an altitude of 100 kilometers. Here's an overview of some progress and achievements:
Key Components
Interstage Coupler Redesign: Our previous interstage coupler design encountered significant stress issues. In response, I have redesigned the coupler to increase surface area contact between the coupler and sustainer tail, drawing inspiration from the Super Loki design. This redesign aims to mitigate stress concerns and improve overall structural integrity.

Engineering Approach
Both components underwent meticulous design, manufacturing, and analysis processes. Utilizing Autodesk Inventor, I developed detailed changes, while Solid Edge FEA facilitated stress and deformation analysis. Adhering to ASME Y14.5 GD&T standards ensured precision and reliability
Achievements
Simulated rocket structure and dynamics using RASAero II software, aligning with our goal of reaching 100 kilometers.
Designed a differential drag interstage coupler and fin can, prioritizing adherence to industry standards for geometric dimensioning and tolerancing.
