I've just finished the Space Vehicle Dynamics course. An awesome collection of videos that I'm sure I'll refer back to as I've just started a new role as an ADCS Engineer. Cheers Dr. Ross!
Thank you for watching, and I hope it's helpful in your job. A good way to stay connected, and get notified of future content is to connect with me on LinkedIn, www.linkedin.com/in/ProfessorRoss
Professor, in the video of the wheel, before the student rotates the wheel downwards, the angular momentum vector is pointing in the, let's say, x hat direction. I understand that the chair rotates in the way to keep the total angular momentum in the y hat direction equals to zero, but what about the conservation in x hat direction?
Hi. People always tell me that rockets work because they are throwing something (burned fuel at high velocity) and that is why they propel forward. They say it is the second law of Newton. You need to throw something (backward) to move forward. So I do not understand how CMG can provide torque. Can CMG be used for propulsion?
Many would be tempted to say "no, CMGs can't be used for propulsion" since they just affect the rotational state of a craft. But YES, they can. You can have interesting effects where propulsion happens, like in this video by my former PhD student, Professor Phanindra Tallapragada: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dpKjSDrhfXc.html
Have you done any presentation of yourfluid dynamics concepts in a large glass aquarium with an additive of the substances found in yellow highlighters under blacklight or other light to attempt a visual effect of the situation?
I haven't done this, but it sounds trippy. Makes me wonder, are there any commercially available demonstrations of fluids which use colors that would show up under black light? I have a video of myself wearing blacklight paint, but a blacklight fluid sounds cool: instagram.com/p/CJfWOfjlTmT/
@@ProfessorRoss I got the idea from watching doc Edgertons videos at MIT. He also added a stone light to capture certain wave timing effects that allow the model to look as if it were standing still or for showing multiples of certain frequencies. Also they used all the same method for a mechanical model of a black hole
Also they do it at the navel research lab and I'm the physics class the navy teaches to show wave properties in great detail but not a cool as that black hole model
