🚨 ANNOUNCEMENT 🚨 Due to problems such as chamber pressure overcoming tank pressure, combustion instability, variable mixture ratios, and just generally not understanding the complexity of the issues, KegRocket will be pivoting to a hybrid propulsion system.

In light of the Starship launch attempt, we are happy to share that our main ox valve actuator is actually strong enough to destroy the valve if it becomes stuck.

Think of all the wonderful expansion ratios that the atmosphere has taken away from us
Shutdown of a Raptor vacuum engine in slow motion. The engine’s nozzle is sized for use by Starship in the Earth’s upper atmosphere and outer space, so operation at sea level and low chamber pressures results in flow separation creating visible rings in the exhaust

KegRocket is designed to be relatively compact to make handling and ops easier. However, it's still a chonker.

This project is full of so many “we’ll figure it out when we get there” things when it comes to funding, design, and procurement. Securing our set of flight LOX valves was one of those milestones. Feels good.

It aint ideal but it's a way to fit a 425 in-lbf actuator in the forward airframe for the ox keg vent valve.

If you know KegRocket, you know its parachute bay is woefully undersized. The bay has now been fully packed for the first time. Charge testing soon!

The technical banter on the other side is not great/nonexistent. Same problem with IG. Appreciative of our unhinged aero community here on Twitter.
Twitter will be our primary for the foreseeable future but we’ve gone ahead and parked a couple of accounts if you’re interested…..

The paint sample is complete and looks pretty nice. After a little testing, this will likely be the main color for the rocket.
