    needing to learn about flight

    My name is Chris and I need to learn more about flight for this school project. Can anyone help me?

    Chris, which part of flight is the project about? It's a big topic, which could mean:

    How one learns to fly a plane.
    What makes a plane fly.
    The history of flight.
    What's it like to pilot an aircraft?
    etc.

    If you could narrow it down we could help a lot more.
    The opinions and statements of this poster are largely based on facts and portray a possible version of the actual events.

    Well,I pretty much want to learn all about all the forces and stabilities. I already know the names and a lot about the stabilities.

    I just need to learn how the three stabilities are created for the plane. And perhaps some more on the four forces.

    I'm only 11
    I'm only 31. Never let someone put you down just because of your age. Being bright and inquisitive is far more important than being smart. Someone (James Thurber) once put it this way: "It's often better to know some of the questions than to have all of the answers."

    Here you go: http://www.nasa.gov/audience/forstudents/5-8/features/what-is-aerodynamics-58.html
    This should help somewhat with the aerodynamics questions.

    For stability: http://www.airplanedesign.info/19.htm

    If you need anything else or have any other questions, please let me know.
    Unfortunately in science what you believe is irrelevant.

    Good afternoon, Chris,

    You may also want to look at the NASA Glenn Research Center's Beginner's Guide to Aeronautics.

    Have a good day!

    Jango, the 4 forces idea is pretty simple. 1.Gravity or weight pulls the plane down. 2 Lift opposes gravity, lift is produced by the wing moving through the air. If you turned the sail of a yacht on its side, it would be pulling up sort of like a wing. A propeller is shaped like a wing and acts like a wing on the air. 3. Thrust is what moves the plane forward through the air, either by a propeller or a jet engine or even both, or a glider being pulled down by gravity. 4. Last is drag, of two kinds, the simple drag of going into the wind, just like running or biking into the wind; and the other and more complex drag that is created by the wing making lift.

    Not really...in a turn, loop, or most any other maneuver, lift does not oppose gravity. A better way to state that would be 'Lift is the part of the resultant force vector that's perpendicular to the flight path, and drag is the component of the same resultant force vector that is parallel to the flight path, acting in a direction opposite the motion of the aircraft.

    Matt, I knew someone could find an exception to what I wrote. Guess what, after a plane breaks up in the air , the wings no longer make lift to oppose gravity either. And the wings on a missle don't make lift either.

    I was trying to make it somewhat direct and simple for the young man.

    PS did you know that the prop does not always produce thrust, either? Someitmes there is no thrust when the engine is off or even reverse thrust after landing. Or maybe that is reverse "resultant force vector", to use some big words.
