README.mdImpulse Drive
In Star Trek universe, impulse drive is a propulsion system of spacecrafts for interplanetary travel. This project is trying to design a real-world impulse drive. The basic characteristics of this engine are
- Electric propulsion
- Large thrust
- Long specific impulse
- No or little moving parts
- Good scalability
- Low cost
We'd like to make it easy to implement, so people can build it as a hobby project.
NOTE: Please turn on git LFS when cloning this project.
Method
There are many different engine designs for spacecraft propulsion, check wikipedia for a list. The only one design among them that fits these requirements is magnetoplasmadynamic thruster, a.k.a, MPDT or MPD thruster. More details in MPD.
Our design is based on MPDT, with several significant improvements.
Design
The principle of our design, and a detailed introduction of modules are in Design
Disclaimer
MPD thruster is operated by LETHALLY high voltage and current. If you don't have enough knowledge and experiences on high voltage electric, please keep extreme cautions on insulation.

Questions
How big is the Control PCB?
It measures 43.2 × 41.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Control use?
31 parts, built around the NE555. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Control KiCad files?
From the gongminmin/ImpulseDrive repository on GitHub, at the commit this page was made from: the board is Circuit/Control/Control.kicad_pcb and its schematic Circuit/CapacitorBank/CapacitorBank.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Control design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
