I am posting this video as I think it is pretty relevant to the amateur/experimental community. Aluminium in some form or another has been the go-to for aerospace projects but one must look at all the pros and cons of a material for its intended purpose to make the best decision. As you will see in the video, stainless steel is quite suited for what SpaceX is hoping to do.
So, I challenge you to think a bit more next time you carry out a material selection process. You may end up back at the tried and true materials but you might also surprise yourself and find others are more suited for your application.
[For those who want more: The plots in the video of the materials are called Ashby plots and are commonly used for material selection, you may recall them from your materials science papers at university. There is software you can buy that displays these graphs and with user inputs allows you to pick the best material for your application.]
Joe launched his 1/48 scale Falcon Heavy back in June, he has now tested the second stage in anticipation of an all up flight test!
Make sure to head over to BPS.space to buy your own Signal flight computer to do this yourself!
Joe Barnard of BPS.space has flown his 1/48 scale Falcon Heavy model demonstrating the ability of the Signal flight computer to control a 3 core rocket. Each core was equipped with its own Signal FC and TVC (Thrust Vector Control) mount, by firing the two core boosters at liftoff the combined TVC control allows the rocket to pitch, yaw and roll about its axis.
As is demonstrated in the video below, the rocket executes a 20° roll program after liftoff and holds this until burn out before the centre core takes over and flys away.
The model even has a second stage fully equipped as well, lets hope we see an all up test soon!
A pretty awesome feat!
I’ll let the video do the rest of the talking!
