I'm a developer. I tried (mostly for fun) to create a realistic physic engine.
I try to sum all forces (here thrust) applying to an object in two composantes: an acceleration vector and the angular acceleration.
I read a lot about torque and thrust but there is still some stuff that I can't figure out.
Let's take a exemple: Imagine a plane(or space craft) with two motors each placed at the opposite side with respect to the center of gravity. If they have equals thrust I figure that I can modelise them by a single thrust vector placed on the center of gravity equals to the sum of the thrust provide by the two engines. Is that right?
What's happen if one motor delivered 10% less thrust that the other one, how my thrust decrease, how to compute resulting torque ?
Did I loose or gain efficiency if my thrusters are placed at the back of the plane and why?
I try to find a mathematic model that could work with any number of thruster placed at different position of the air-craft.
