Summary
| Description |
English:
This is the current design for the Astra Rocket. This Serial Number 1 was tested horizontally at the Alameda test facility. 3D-Printed in the Inconel superalloy with integrated regenerative cooling channels running up the bell and combustion chamber (liquid fuel runs in the purple cap, and around the tapered bottom ring with equal pressure up a multitude of channels running to the top before looping back to the fuel injectors at the top. This keeps the engine from melting from the heat of combustion with no insulating layers needed inside.
It is fueled by Kerosene and liquid oxygen (LOX). The first stage of Astra is powered by five Delphin engines of 28 kN thrust each driven by battery-powered pumps
