# Popper Directory

Popper is a small (2 kgf) RCS thruster designed to run H<sub>2</sub>O<sub>2</sub> monopropellant. It's small enough that it *should* be testable in Gerry's backyard (he offered).

## Design Considerations
- small scale engine (2 kgf) reaction control thruster
- uses catalyst and 85%+ H<sub>2</sub>O<sub>2</sub>
- simple On/Off valving = not variable thrust throttle
- can be used as 1 off or combined into *thruster pack* (TP) of 4/5 engines and control valves
- millisecond reaction time(?)
- threaed top to screw into threaded base of TP block
- simple to (commercially) 3D print in metal
- temperature probe(?)
- pressure probe(?)
