What is the difference between speed and thrust? And what exactly is thrust? From what i have read, a smaller, high pitched prop produces more speed and less thrust than a larger diameter, lower pitched prop. Now if i understand this correctly and in extremely basic terms....the larger diameter chews up more surface area in the air which gives the plane more "pull" or thrust at a stand still and the pitch must be lowered in order to maintain RPMs. And a smaller diameter prop can have a higher pitch which allows the plane to travel faster with higher RPMs but due to the lack of surface area, you sacrifice thrust. Someone correct me if i am wrong please. Now would a larger diameter prop with the same pitch of a smaller diameter prop produce more power or thrust than the smaller diameter prop (pretending engine performance and RPM is the same regardless of prop size)?
Thank You all for help.
