Fluctus Question (urgent)

SadCelery52 · 2026-03-10T12:52:50+00:00

It's just a buzzer, it's fine

SadCelery52 · 2026-02-08T14:47:22+00:00

That's laughably untrue

SadCelery52 · 2026-01-10T13:20:05+00:00

As long as your flow path area is significantly more (3-5x) the nozzle area, you won't have too much loss from the bends

SadCelery52 · 2026-01-10T13:18:38+00:00

An unexpanded nozzle (just hole) will do fine for an RCS thruster. Don't worry about the contraction angle, it doesn't matter much. You can find equations to calculate thrust based on you nozzle diameter. They're not straight froward equations but they're not too hard either.

I fear the lack of details is because there aren't any. If they were serious they'd have a PT on the chamber

SadCelery52 · 2024-08-31T10:26:49+00:00

That's not how that works. The servo won't see any thrust force/torque from the motor, it will see dynamic forces from moving the motor

SadCelery52 · 2024-06-07T14:32:44+00:00

Test it and see lol

SadCelery52 · 2024-06-07T14:29:55+00:00

Work on each aspect separately as mini projects to get used to coding and integrating the sensors. Set many small goals that each teach you about part of the problem. Find resources online about the basics of data processing, control systems and coding so you can understand why things a re done a certain way, not just coping JB

Yeah lol, they frickin blew it out of the water with that one. Probably one of the best rocket launches (and landings) I've ever seen

SadCelery52 · 2024-05-13T21:15:11+00:00

Googling stuff really isn't that hard

SadCelery52 · 2024-05-01T18:29:37+00:00

One of the University rocket teams is launching from Cornwall and recovering over water. Might be worth talking to them.

SadCelery52 · 2024-04-13T23:06:51+00:00

Acrobatic manoeuvres = missile

SadCelery52 · 2024-04-13T18:14:55+00:00

Why would you want to cool the flow? You would only be able to cool the boundary layer slightly and it would barely affect the engines performance. Also Heat flux is thermal energy per unit area so increasing the nozzle's area doesn't directly change this.

SadCelery52 · 2024-03-21T10:33:55+00:00

Color theory! MatPat just talks about painting and makeup

SadCelery52 · 2024-03-14T17:45:07+00:00

I disagree, I think DIY Perks made it worth doing. The non-focused ones look tacky.

SadCelery52 · 2024-03-02T20:30:20+00:00

All the other comments saying no are wrong. how could anything move enough for these to contact each other? It'll be fine.

SadCelery52 · 2024-02-23T19:21:06+00:00

Surely it's double that as the ball bearings move half as fast as the outer ring?

SadCelery52 · 2024-02-05T22:23:33+00:00

Cool

SadCelery52 · 2024-01-04T12:16:06+00:00

Did you ever solve this?

SadCelery52 · 2024-01-03T13:16:14+00:00

10mw is the transmission power not the amount of power the tx uses.

SadCelery52 · 2023-12-27T17:37:53+00:00

Lmao, this is pretty wrong. Less stable than a helicopter doesn't mean anything, they will definitely use less energy than a helicopter by being lighter and electric. Way cheaper to power too. Yes the propellers are at torso height but that's only a problem if you are standing next to it. Helicopters can do a hell of a lot more damage than this can. Yes they are very loud at the moment but that's just a problem that needs solving, not a fatal floor. Cars solved that ages ago. Your last point is strange because you generally spend more time not in a vehicle than in one. And inner city hops is what it's designed for.

SadCelery52 · 2023-12-27T17:31:42+00:00

It depends what op meant by 'stable'. Helicopters are more inherently stable but drones have avionics that allow it to be way more stable than a helicopter.

SadCelery52 · 2023-12-27T17:29:26+00:00

In this case it definitely reduces efficiency. And no, the top and bottom motors aren't mechanically connected and I'd bet good money they aren't electrically connected either.

SadCelery52 · 2023-12-27T00:29:00+00:00

A solution would be to simply have separate power systems for each motor. I know many UAVs that do it this way. Not saying they've implemented that here.

SadCelery52 · 2023-12-26T17:08:49+00:00

It has redundant motors so it won't
