How does the trailing wingtip vortex generates drag on an aircraft? Since the vortex is trailing behind the wing how does it create a pull on the aircraft. I heard wingtip vortex causes and induced angle of attack on the wing is this true? I read wiglets reduce this vortex in-turn reducing drag, can you please elaborate on wiglets also?

I try to change stuff in the aircraft.cfg to make the submarine I downloaded go faster, but it keeps going the same speed. I’ve lowered max gross weight and empty weight, and raised the rated N2 rpm. What do I need to do to make it go faster?
