Military, but they gave it to a student because they are out of money.
No shit, I just wanna know if itās Northrop, BAE, Lockheed or GA.
but they have this tech already.
Something way out of what i can do right now. I am just challenging myself to the highest possible degree. Plus, itāll be fun for sure.
Basically i want to be able to somewhat, like, uh, launch and land small rockets.
Even though burn time is way less than 5 minutes. My inner (word i canāt use) doesnāt like drift. Well, 1% is rather low and since this is a rather small rocket it wonāt be in air for too long. Iāll consider it, thanks. Iād thought about just double integrating acceleration from the beginning but I never accepted it.
I think you can have 2 ( 3 would be preferable ) sensors 1 at the top of the rocket and one at the most possible bottom. This way you can correct deviation in the course.
That accounts for nearly all drift.
What can increase drift in a system like a rocket. Does sudden jerks contribute to it for example. Besides having multiple sensors, what ways are there to reduce drift.
Sudden jerks arenāt usually a huge issue. EM interference are more of your concern.
Reduce em interference.
Didnāt know that, thanks.
Theyāre very sensitive to magnetic fields. Putting shielding helps a lot. Not that itās entirely feasible.
Edit: Faraday wouldnāt work well.
I am not sure about that. My study in fluid dynamics is limited, but I remember that laminar flow is is needed for airplanes and if I recall correctly turbulence causes some drift. I might be wrong.
Thatās significantly more than Iāve experienced in my 3ish years of using them.
My experience isnāt in aeronautics, so i will defer to you all.
Uh, did you use the same board?
Yeah. If I were in the lab, Iād share a pic.
what is 1% expressed in meters per time unit. In your case meters/5min.
So the 5 minutes, we had about 150m of total change in position. We experienced 1.5m of drift, on average.
We saw approx. 2.2m at max.
Btw do you take in consideration the amount of range of your rocket in 15 secs ? 15 seconds is a lot of time btw.
So what, thatās 1.5m / 5min => 0.005meters / sec. Compared to 1meter/15sec => 0.066meters / sec.
0.005meters / sec
vs
0.066meters / sec
hmmm
Well again, this rocket is only going to launch and be airborne for a short period of time before attempting to land again. Maybe maximum a minute or something. Also, to answer your question, not at high velocity and a maximum distance traveled of like max 1km or 500m. Probably a lot less, more like max 100m.
Are you expecting to land it like spacex rocket ?
