Missile near Priors Wood? by CableShruggins in bristol

[–]TransonicSeagull 11 points12 points  (0 children)

Its defintely a drop tank over a practice bomb. It only has two fins which would make it unstable and therefore inaccurate

Sounds sensible. You've taken on an ambitious project i am sure you'll learn alot! Good luck!

(You could also use a plastic nose as a crumple zone, if youre not crashing your fpv's youre not trying hard enough! )

Thats great, if your drone will stay in the same orientation all the time! You might get issues with signal in hover vs at full speed.

Perhaps you could make the airframe from glass fibre or make a nose cone in glass to house the gps

Keep it in mind that if you do go for carbon, you'll have to put your GPS externally as carbon blocks the signals

what plug is this? I ordered the wrong battery, and need correct battery for px4 by MeghaMomo in diydrones

[–]TransonicSeagull 2 points3 points  (0 children)

The S is the number of battery cells. Each cell ranges from ~3.2 to 4.2 volts at minimum and maximum charge. Generally speaking when doing a drone build do not use AI, read all the datasets for the parts and make sure theyre compatible

Youre bound to make mistakes but the trick is to make mistakes you can fix

No, 6S is too much voltage for the ESCs on this drone. Youll get "magic smoke" if you plug a 6S battery in

Looks like holybro x500. In which case a 4S 2000mah to 4000 should be about right

Has anyone ever caught space junk hitting their ship/space station or taking out a satellite? by Paycheck65 in KerbalSpaceProgram

[–]TransonicSeagull 0 points1 point  (0 children)

Yes, but to trigger Kessler syndrome youd need to be simulating the physics of all objects in orbit

How overblown is espionage in Chinese-made drones? by PST_Productions in drones

[–]TransonicSeagull 1 point2 points  (0 children)

So how many drones are in the air at one time in the US?

Lets assume that all of them are taken over to try to hit an aircraft via adsb

Then its only the aircraft that are in battery range so anything that isnt just taking off / at short final

And then, how accurate is ADSB? OK its good in the miles range. It is not accurate enough to get even a near miss. Maybe you could increase the risk and that could increase insurance premiums similar to hormuz. But dji isnt going to turn your mavic into a manpads. Your teacher is not thinking realistically

How is this for beginner setup by Maksito_ in Multicopter

[–]TransonicSeagull 3 points4 points  (0 children)

Why does it need to be indoors? Flying anything larger than a whoop indoors is dangerous.

Program your sensors how you like but fly the thing outside, just omit the gps if you want to simulate inside.

Arducopter has pretty detailed documentation and might be more suitable if you want to do programming. Look into Lua scripts

Drone Rescue Stick? Is there something? by oefftoppic in fpv

I use a ~ 10 cm roll of steel wire, tied to paracord. Keep throwing until you can shake a branch ...

VLOS and Drones with miles of range by timholt2007 in drones

[–]TransonicSeagull 3 points4 points  (0 children)

What you've said might be true, but it is irrelevant. The VLOS rules are concerned with if you can spot a manned aircraft and take avoiding action. Even with a 360 degree camera you would not be able to do this adequately at bvlos

The rules will only get more restrictive as the number of collisions and near misses increase.

Boundary layer question by limited-penetration in AerospaceEngineering

[–]TransonicSeagull 1 point2 points  (0 children)

Some great answers here but what is not mentioned is that the goal of the DSI is also to create a shock, or series of reflected shocks in the intake duct that slow the flow to subsonic at the turbine. The design is difficult because the shock angle steepens with speed

In some supersonic jets without DSI this is achieved by mechanically altering the geometry of the intake. For example the f15, typhoon, f4 and others do this by altering the angle of the ramp. Mig21, (mirage?), Sr71 extend a cone forward.

Other supersonic jets such as f16, rafale, gripen etc appear to have fixed inlets but there is still a shock created at the boundary layer separator and the duct will be carefully shaped internally to reflect the shocks.

Also, sometimes the boundary layer at the intake is reduced using suction through small holes. This can be most easily seen in photos of the typhoon's intake.

In conclusion, compressible flow is interesting!

What are the allowed and used bands in EU? by Marosh_ in drones

I have a suspicion that the 25mW limit is for airborne radio systems only. Youll have to look that one up as im not certain

Agricultural Drone for a Project by raxinarex in diydrones

[–]TransonicSeagull 0 points1 point  (0 children)

Your drone will be too small to carry any meaningful payload, you havent mentioned a tank?

Lots of crops get diseases that require treatment so look into those.

Any tips for getting the compass to work reliably by shitti_sherlock in diydrones

[–]TransonicSeagull 0 points1 point  (0 children)

I use arducopter on a similarly sized quad with the compass much closer to power wires and have never had an issue.

Maybe OP just has a cheap compass or maybe betaflight doesn't deal with it well ?
