I lack some of 3 dimensional understanding, and now I experience some problem while trying to understand roll yaw and pitch angles. If there is somebody who may provide me some source recommendations (animations, videos etc.) or explain it from here I would be appreciated.
What are all these ang...
I also have a draft typed for that, but it is so unclear that I hesitate to post. I almost think it is a better fit for Physics or Math SE, as ultimately it is about rotation formalisms.
One is to say that heading, pitch and bank are the angles by which you would have to yaw, pitch, and roll, in that order, in order to get to the actual attitude from a reference attitude (lateral and longitudinal axes level with the nose pointing north).
... with the caveats that the yawing motion must not be left and must not exceed 360 degrees; the pitching motion must not exceed 90 degrees; and the banking motion must not exceed 180 degrees.
The other way is to just directly define the words "heading", "pitch", and "bank".
Heading is easy enough to define. It's the horizontal direction that the nose is pointing.
(Later I'll have time to state that more clearly.)
Pitch is even easier. It's the angle between the nose and the horizon.
Bank angle is slightly trickier.
Define "wings-level" as the situation in which the lateral axis is parallel to the horizon, and the top side of the aircraft is facing the sky rather than the ground.
Then bank angle is the amount that you would have to roll to get to wings-level (except that the sign is flipped).
According to Newton 3rd law, every action has reaction force in the opposite direction. That's how spaceship can move in space. That's why helicopter needs a second propeller in the back to prevent it from spinning in the opposite direction of the main propeller.
But why single propeller planes ...
This question reminds me of a video I once saw of an indoor airplane. It was extremely lightweight, probably weighing less than a sheet of paper.
It had a propeller, and the propeller generated a huge roll torque. The reason this particular airplane didn't rotate around the longitudinal axis was that one of the wings was about twice as long as the other one.
That might be an exaggeration, but the asymmetry was very obvious.
