Nucleus Launch Series

Stepping away from the amateur side of things but this video series on Nammo’s launch of their Nucleus sounding rocket is pretty cool and worth a watch.

The 30kN thrust, 356mm dia hybrid rocket uses hydrogen peroxide and HTPB fuel, and flew to 107.4 km in September of 2018, making it the first hybrid rocket to reach space.

Rocket engines fascinate me, the history of them even more, so check out this link and explore the NPO Energomash showroom in 360°.

And if you are still after some rocket engine history, I thoroughly recommend “History of Liquid Propellant Rocket Engines” by George P. Sutton. Well worth it to have on your shelf.

Robert Truax – More than just Sea Dragon

Curious Droid (worth following!) recently posted a video about Evel Knievel but more importantly Robert Truax and his X-3 Volksrocket design which would have made Knievel the first private astronaut to reach space. Truax is most known for  Sea Dragon and the Thor missile, so is no stranger to rocket engineering.

Why is this relevant? well, Truax although a professional worked out of his garage and put the X-3 together out of surplus rocket parts. Powered by four Rocketdyne LR101 engines the rocket would loft its single passenger to 62 miles and return them safely. Unfortunately, it never flew but was extensively tested and modified under a Navy contract for a sea-launched satellite launcher, designated X-3A.

The backyard engineering of this project is pretty amazing, and it is a pity it never made flight but others are following in the footsteps so stay tuned!
