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.
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!
The rocket was restricted to 4000ft altitude but looks like it all went off without a hitch. Not sure about successful chute deployment, the slow-mo video appears to show the chute shred from the fin can stage.
Robert Clark over at Polymath has posted an interesting blog post titled ‘Orbital rockets are now easy, page 2: solid-rockets for cube sats‘
Robert explores the use of solid rocket motors to put a CubeSat into orbit. Leveraging of current amateur and student projects which have been developing large and successful motors, an orbital launcher may be in the realms capable by such a team.
Worth a read to peak your interest!
