Hello friends,
I have a question, why the thrust of the engine decreases while the velocity increases? thank you

and my other question is what is the relation between engine thrust and velocity and throttle setting

Because i have a dilema, because i know that if i increase the throttle setting (i increase the fuel consumption) the thrust will increase and if the thrust increase the velosity will also increase, but from other hand i see plot of thrust versus velocity in which i see that the thrust decrease when velocity increase, so how can i understand that

thank you for helping
