I feel like experimenting with all sorts of weird configurations of helicopter blades to see if I can make a 3D printed aircraft as efficient as a frisbee.
What simulator to use?
>>8098132
>as efficient as a frisbee.
frisbees aren't that efficient.
>>8098132
what 3d printer do you have?
>>8098132
>efficient as a frisbee
efficient how?
low fuel use?
aerodynamics?
>>8098220
>I want a long-airtime remote aircraft for something.
Admit it.
You want it for perving on young women.
>>8098256
Nah.
I want to hover it outside John Key's window with a protest sign.
>>8098400
That's why I wanted to try out a helicopter with frisbees for blades in a simulator!
Hence, the point of this thread.
>>8098415
>>helicopter with frisbees for blades
wait what. Not like pic related, which is optimized to act like a wing in forward flight?
You want to have frisbees spinning around like blades? I think you'd have a very difficult time simulating that.
Not to mention, the reason why frisbees fly so far is because rotation causes the boundary layer to become turbulent, preventing boundary layer separation. There are much better ways to do this that do not involve rotation.
>>8098431
I don't see why it would be hard to simulate in a simulator.
Some tool for engineers where you specify the proportions of a wing? Yes, but what I'm looking for is something where I can import a 3D model, give it some motion, then let the computer crunch the numbers.
>>8098442
No such thing exists. You gotta convert the model into something reasonable, make a mesh out of it and its surroundings, assign boundary conditions, select appropriate mathematical models and then interpret the results, because program will output something, but it doesn't have to be even close to reality if you fucked up somewhere.
>>8098459
That is pretty much what I meant, sounds a lot like a smoke simulation in blender.
>>8098442
>>I don't see why it would be hard to simulate in a simulator.
it's fluid goddamn dynamics of course it's gonna be hard to simulate. Not only that it's fluid goddamn dynamics where turbulence matters and shit rotates.
>> I can import a 3D model, give it some motion, then let the computer crunch the numbers
no such tool exists. It is not as simple of a process to just import a 3d model and let the computer crunch the numbers.
>>8098466
there's a pretty big difference between making stuff that looks pretty and making stuff that's works in the real world.
Also, pure and simple aerodynamics are only a minor thing in helicopters, vibrations and elasticity are much more important and complex.
>>8098442
>a helicopter with frisbees for blades
>simulate in a simulator
Sorry dude computers don't work like they do in video games and movies, for an accurate simulation you would use something like MATLAB and program the geometry of the frisbee and compute the fluid dynamics your self.
>>8098476

Easy tools like blender that you are familiar with are for creating relatively fast cheats that look acceptable to a human. There isn't a standard tool with a default method that gives acceptable results for the majority models. It's highly specific to the exact engineering problems you are trying to solve, in the conditions you are working with.
>>8098471
Blender does actually work for turbluence simulations; if you put a big box in a smoke flow for example, you'll get the real-life result of a patch of turbluence directly behind the box with the laminar flow merging further behind.
So why can't I get something that does exactly the same thing but able to also calculate the force of the flow on the object?
>>8098472
Not so important for anything smallish made of extremely strong and light plastic.
>>8098488
Show me a simulation in which a laminar flow transitions to a turbulent one in blender. Not to mention in the real world we are more concerned with forces rath than the path fluid takes.
>>8098488
>Blender creates visually believable turbulence in some cases
That's what it's for. That doesn't make it a physically accurate simulation. It makes it believable in relatively simple cases.
>>8098540
But what aspects of the physics can't be captured through an only slightly more sophisticated form of the approach Blender uses?
>>8098581
Because "look believable" and "is correct" has a long gap between them.
>>8098132
Try making it as efficient as a bumblebee
>>8098664
Long story short - Blender uses very simple equations that calculate the fluid motion at very low precision and nothing else. If you want to use that, be my guest - you'll get something out of it. But I doubt it will be better than nothing.
>>8098682
But what's missing from the calculations?
>>8098685
Pressure for example?
>>8098690
That's why I'm looking for something that's the same, but with such things included.
>>8098697
Nothing for helicopters, then.
>>8098698
What?
>>8098664
Damn, that's hypnotic.

She's at least in high school. So, it's not pedophilia, it's hebephilia, which we've been doing forever.
>>8099835
And in my case, it's more jealousyposting than actual attraction since I'd rather have a girls body than a guys, and in turn date a guy rather than a girl.
>>8099835
>She's at least in high school. So, it's not pedophilia, it's hebephilia
I don't think you understand what either of those are.

>They weigh quite a bit yet are still able to hover for quite some time considering their speed.
Not nearly as much as a proper glider of the same weight and span. Unconstrain span and you can get WAAAAAY better performance yet.

Learn English, faggot.
It's a pretty straightforward definition.

>Hebephilia is the strong and persistent adult sexual interest in pubescent (early adolescent) individuals, typically ages 11–14 (see the Tanner stage). It differs from ephebophilia, which is the strong and persistent sexual interest to those in later adolescence, approximately 15–19 years old
Retard, does that devil look "early adolescent" to you?
