currently only helicopters

still pollen
#

Is this available anywhere?

sterile turtle
#

no its not going to be available for awhile sorry

#

i want it to be perfect before releasing it to the public, also user friendly. so i will have to keep it simple to set up and document it well

@sterile turtle are you calculating lift (force and direction) based on the individual blades passing over the swash plate or is it simply adding input and modifying the direction vector. I'm doing something similar and am not getting very good results with a more simple model.

it is rather complex to be honest. i did this a while ago and im working on something else right now. but i advise you to research Helicopters deeply to understand the basics of how a helicopter moves.

Gotcha, no worries. I'm working in C++ and my current approach is the following: (maybe you can advise if I'm on the right track)

LiftForce = (0.5 * AirDensity * FMath::Square(MainRotorAngularVelocity) * (MainRotorBladeLength * MainRotorBladeWidth) * CL);

Angular velocity is derived from converting RPM to rad/s. Rotor length and width is in cms. CL is a linear function for now based on blade pitch angle.
I'm aware that this wouldn't replicate many behaviors like translational lift, dissymmetry of lift, transversal flow etc. I've been reading through manuals and booklets and looked through a lot of source code on GitHub that attempts to do the same.
Unfortunately most of my attempts don't yield anything that feels remotely to what you've shown in your video.

the video above is pretty outdated and the flight model is a lot more refined now

#

also keep in mind that transmission and engine calculations have to yield realistic results to maintain a solid simulation

Why not use the jsbsim add-on ?

sterile turtle
#

atleast for multiplayer games

#

for sim games that are singleplayer focusing on flying its a good option tho

and not real games

# main spire Well it's been proven in Outerra to work in a multiplayer server..... But no wor...

jsb sim is not a good option for multiplayer games, that are aiming to be fun and engaging.
jsb sims solely focus is to run simulations based on real data, with that said is for the average sim enjoyer it might be an option. bun games focusing on gunplay and engaging interactions this is not it.

thats why im not using this btw library/Plugin.

instead write a less computational heavy simulation which is enjoyed by the player.
