Video Caption: A short video about my graduation project for my study in applied Mechatronics Engineering which I performed at Copenhagen Suborbitals. My project is a prototype of a rocket engine gimbal thrust vector control system, which was designed and built in 2016.
Paul Breed has a new update on his quest to build a nano-satellite launch vehicle.
Paul first started looking into this back in 2012, even going as far as entering the Space Frontier Foundation, NewSpace business plan competition. Recently he has resurrected his plan and idea with a newfound approach. Paul is no stranger to rockets and space, having entered in Level 1 of the Northrop Grumman Lunar Lander Challenge with his VTVL rocket “Blue Ball” and level 2 with “Silver Ball”.
Unreasonable Rockets current approach for a nano-satellite launcher uses the OTRAG example, where common propulsion modules (tanks and engines) are strapped together to form a larger rocket and staged as necessary along its flight path. This common propulsion module approach was first tried in the 1970s, although never making an orbital flight, and is also the approach being used by Interorbital Systems for their N-5 rocket.
Work has been carried out on carbon fibre tanks and it is now that a mass ratio (wet mass to dry mass) of 15 has been achieved with the current set up. Work now continues on an extended version of the tank for testing and motor design, that will be 3D printed. An artist rendering of the proposed rocket is shown below.
This promises to be a very exciting project and one that will deliver.

As with any rocket or spacecraft, control is a vital part for it to be able to achieve its goal. It is also one of those very in-depth specialist subjects that we all wish we could know, but sometimes its best left to the people who do it for a day job.
But we can still understand what your control engineer on your project is talking about, thanks to Brian Douglas.
Brian has created a series of control system lectures that you are able to watch on youtube, and the best thing about it, they are all taught in a way that make it understandable and easy to pick up on.
In Brians latest video (posted below), How to Land on a Planet, one can get a better perspective on what it took for NASA to land Curiosity on Mars back in 2012, and also all previous landers.
This work not only applies to NASA, but there are also private companies developing planet landing technologies, notably Masten Space Systems. GLXP team Astrobotic teamed up with Masten to help develop their software needed to land on the moon, a video and explanation of this test is shown below.
So I highly recommend checking out Brians youtube channel, watching all his video’s, and then hey, maybe you will become the control engineer for your project!
