Funky trees ground effect!!!
If you dont know what the Ground effect is or how it works
>click here<
Example crafts:
Setup:
Save the engine as a SubAssembly
NO WINGS WITH ENABLED WING PHYSICS EXCEPT VERTICAL STABILIZERS AND NO CONTROL SURFACES ON THEM!!
Place the engine at the CoM of your craft and make sure it gets enough air
((log(-AltitudeAgl+Wingspan+1, 1.025)*1) * abs((TAS * 3.6)/100))*0.014635
This is the coding of the input. When the wingspann of your ekranoplan is for example 30m you have to change the code to
((log(-AltitudeAgl+30+1, 1.025)*1) * abs((TAS * 3.6)/100))*0.014635
Insert the weight(in Kg) in the powerMultiplier of the engine
Ad an gyro which is strong enough but not too strong and insert in the Yaw input
Yaw*TAS
On bigger ekranoplans you want these input seperated engines to lift it out of the water and once this is done they are being shut down
It is working on normal planes too but I cant recommend doing it.
But when you do it anyways I advise to ad another 0 in the max of the input controller, because they are not designed to maximise the ground effect. Of course you can forget about the wing and gyro stuff then.
About the function:
I created the function >here<. If you are more interested in it I advise you to get the app and open it there.
Other ways for ground effect:
- Ground beffect exists for heli props too. Maybe someone is motivated enough to get it working with this way.
Some more inportant stuff:
Bug reports in the comments pls!
Questions too!
Its free to use but pls give credit and ping me when you created a craft with it.
Yaay u reached the bottom
Enjoy >.<

@Erebos OK
@MuizTheRailfan try to increase the
*1
afterlog(-AltitudeAgl+Wingspan+1, 1.025)
in small steps until it works@Erebos yes
@MuizTheWeeb have you added the wingspan in the input?
@Erebos nvm, for some reason your GEV engine Didn't work at all. How to fix it?
@MuizTheWeeb no, unless they are angled slightly so they provide lift too but then it should not really matter either if the thrust of the prop engines isnt stupidly strong
@Erebos I am currently making a propeller engined Ekranoplan, does maxRpm also have to be filled in with the Ekranoplan weight number?
@Erebos also I do not know what you mean by "unlisted version"
um... this is the link we are on now...
@Jakee if you send me a link with an unlisted version of it, I can make it for you
WHY WOILL IT NOT WORK
@Erebos
.
Exponential functions exist. It's you wgo hasn't looked hard enough for them. They're done through
pow(a, b)
.Given that you can manipulate a logarithm, I think you also realize that nth root functions are in actuality exponential functions. So there you go, everything you needed... From exponentials to nth root functions.
One note on text formatting with the code style formatting option for your system... You've used a character that it doesn't support. Try to fix that, else people can't copy / paste. I'm being mean here, but run through the spelling once more.
Plz tag funky trees
@SledDriver whoops just realized
@SledDriver ok thx
@Erebos Yes, but if you want people to actually notice your post, you should post the aircraft as public, then link to the engine. A single yellow engine pointing down doesn't exactly catch the eye.
I have example crafts at the top of the discription @SledDriver
@Erebos Nice work, but just a suggestion, it would be much better if you actually built an aircraft demonstrating it.
@ChisP When tagging, you need to use the exact username, here you added a space so I wouldn't get a notification.
@ChisP thx
@Sled Driver
Very smart indeed
