Hi everybody,
From my previous experience this is the place to find very smart people with tons of experience, so i turn to you guys (and girls) for some help.
I've got a new coursework project and i'm trying to make sense of it all. I'm dealing with flight management for the first time time, so as usual there some things i don't quite understand.
To start off, we're not interested in take off or landing, just the cruising part of the flight, during which 65% of total fuel should be consumed. Aspect ratio of the wing is kept constant at 7.
From what i understand, since the velocity and altitude is constant i've got to balance thrust, drag, lift and weight so the flight is steady.
The bit that i don't quite understand is the thrust. I have a couple graphs with engine data: fuel consumption vs engine speed (rpm) and thrust vs engine speed.
Could someone explain how this data is related to the aircraft velocity? That's the primary problem i have at the moment, since i can't do much without knowing the velocity.
Also, from what i can see, two ways of keeping the velocity and altitude constant as the fuel burns off would be either to change the thrust or change the angle of attack of the wing. I'm thinking varying the thrust and keeping everything else constant would be easier. Am i right?
Thank you
