Aerodynamics for palnes

[? Mark]

Hello,

I was searching for a topic regarding aerodynamics, but the only one I found is one-and-a-half years old and refers a mod which was tweaking aerodynamics.

So, the thing is that I am trying to build an airplane. As a matter of challenge, I want to do it without ready-made small white "fans", and without ugly looking buoys. I am making a propeller engine based on motor wheels.

I am countering a major problem - the plane tips to one side as soon as I start it. THen I figured out, it was because propeller parts were tipped to one side, so I have removed the centered front engine and created two symmetrical front engines, rotating in opposite direction (cheked every wheel's direction and speed) and certainly put the propellers absolutely symetric as well.

No effect! The only difference is that now the plane tips the other side.

The plane itself is totally symmetric (on left and right sides), and the center of mass (COM) is right where its needed (so far as my eye-metering tells).

Taking into account that in real life most small propellered airplanes are with one centered propeller, which is rotating in some side (obviusly, duh), I think in Besiege the aerodynamics gives some preference to some factors and slightly neglects the other.

Any advice for that? Would be highly appreciated!!!

There seems to be an issue with the aerodynamics in this game where that does indeed happen without fail. However there is a work around. You can place a standing wing blade in the centre of the aircraft so that the cutting edge is facing the way which the aircraft moves forward. You need this to be straight which cannot be done with the wing blade alone, so put it on a steering block so you can adjust it's angle. This stabilises the machine and stops its unexplained one sided tilt.

You can look up DawnShade's basic plane tutorial. It's helped me build my planes.

I did, and practically my plane model is based on it. I am not copying of course, after all a copy would not fit the box to progress the level.

I didnt get the part about not being able to put it straight without a steering hinge. As far as I can see, the game au contraire allowes it to be only put either vertical or horizontal.

Put a ballast on each wing tip, and adjust them until it stays leval

I have noticed a gravity problem where the left side of the plane is always heavier unless you specifically adjust it like what AKing1 said.

Actually of what I see, the angle of aerodynamic propellers is making lots of disbalance.
Much more than its supposed

i usually fix this problem by adding some vertical stabilization, without it the plane will be unstable

the games "physics" dont work, simply place 4 wings, one on each side of a block, watch it glitch apart, use a big loose creation?, it jerks into pices, as for actual planes, just make a blimp

What's your point here? People build cool airplanes, helicopters and even controllable zeppelins.

It can still fits if you rotate the machine by 45 degrees

Maybe, but my point is that I don't see a point in mindless coppying.
I can just as well download a ready-made smth. from workshop.
I want to learn from videos and tips and then build my own, perhaps little worse but my own.

Put the unpowered wheel behind all of the wheel at the Propeller.






Because Torque is generating from the wheel into the creation, it will roll to it's left or right, causing ♥♥♥♥ to occur. If you put an unpowered wheel behind all of that, it will absorbs all the torque transfering into the creation, thus producing no roll to it's left or right.

There is no air dynamic problem unless the plane's body is full of wings (if it is, remove all the wings in the fuselage as it cause huge problem and replace it with something like wooden panel)
