As i said, i have no clue of the factors influencing drag and aerodynamics.
My idea was (very) basicly this.
We have a forward force consisting of engine power/thrust
and this is counteracted by overall drag.
At Topspeed i have thrust = drag.
So if i if increase thrust (i.e. more engine power) i get a little bit more thrust to accelerate and increase topspeed until
thrust = drag matches again.
is that right so far (remember that english is not my motherlanguage so my terms might be a little bit of
)
but if at the same time i increase a drag factor, i might be able to get the exact same speed as if both factors were lower.
I also recognize that there are other factors influencing that, such as prop efficiency, as it effects the way engine power is converted into thrust
so if i use a thumbrule of
power x prop efficiency = thrust
if i now increase power, i would get more thrust, but if at the same time i lower prop efficiency thrust can be constant.
If the above is right.
Than my general statement, that 2 little faults might eliminate each other without affecting the results (here speed), while just 1 fault would changes the result, is right?
