I’m taking MIT’s 16.00x course on edX, and it’s been amazing so far. Tsiolkovsky’s rocket equation is pretty simple, even for multiple stages. Still, I wanted to create a tool for calculating it anyway since it seemed like an excellent opportunity to combine two things I’m learning: Svelte and aerospace engineering.

The site itself uses Svelte and Flowbite-Svelte, which was the best set of UI components I could find for Svelte for the purpose of this project. I also found a Svelte implementation of IBM’s Carbon design system which I considered using but ultimately decided against.

On the tool, you can calculate ∆V for a simple single-stage rocket. You can also do multi-stage rockets, which are much better at reaching higher ∆V’s with the same amount of weight and fuel.

The tool is hosted at
