Paul Breed of Unreasonable Rocket has picked up his project for a mini OTRAG style launcher, the goal is to have flown a single tube by April 2019, just in time for the Space Access Conference.
For those not familiar, check out my post from a few years ago on the project.
The project will make use of 4″ dia 6061 tube, housing 90% hydrogen peroxide and a yet non-disclosed hypergolic fuel.
Paul has already been making progress as outlayed in the blog posts below,
Well worth a read.
Paul Breed of Unreasonable Rocket has conducted a recent test of his new 3D printed peroxide/gasoline rocket engine.
The engine is designed to test for a OTRAG style nano-sat launcher, discussed here, once performance has been achieved, Paul aims to make it light enough until it fails and then progress onto a flight-weight engine and OTRAG tube.
