How aircraft flaps work

Ғылым және технология

A whiteboard explanation of the theory behind lift and flaps in what is the first of a series that attempts to explain the science behind the technology we use in our RC planes.
I've tentatively called this series "Theory Thursday" but it might also be Technical Tuesday or Whiteboard Wednesday -- you tell me :-)
And if you've got ideas for new theory videos, mention them in the comments below.
Also, if you have any questions about this video, ask-away and I'll do my best to answer them.

    If you think about it, a propeller is nothing more than a rotating wing. It produces lift to create thrust. Bernoulli says that the low pressure area ahead of the prop sucks the plane forward to produce thrust. Newton says the the air is accelerated backward to produce thrust in the same way a jet engine does. Which is true? Both.

    I appreciate that you at least mention that the Bernulli effect as a explanation of why air-planes fly is at least disputed. The Newtonian explanation makes so much more sense and I'm convinced it is responsible for the majority of the lift created.

  • @marcelstanford430
    @marcelstanford4303 жыл бұрын

    As a fixed wing private pilot I knew there were 2 kinds of lift but only the name of the Bernouli lift. I always called the other one "deflection lift" when the flaps were down. The best way to demonstrate both is to take a narrow strip of paper and hold it in front of your mouth. Blowing across the top of the paper gives you Bernouli Lift and blowing below the paper gives you Newtonian Lift. A clean wing is all Bernouli Lift and as you add flap you get less of that and more Newtonian Lift with more drag and therefore slower speed / lower stall speed for landing.

    Totally spot on ... For advanced learners l'd like to add ... Flaps change wing camber & above all wing chord. Meaning increasing angle of attack (AOA) by some 5 degrees despite plane staying in same orientation. Plus control surfaces lose authority at slow speeds &n controls feel mushy

    Hi! It would be nice to see here Lilienthal's Polar Diagram, but anyway comprehensive presentation. Probably worth mentioning (or with more emphasis) - flaps are mainly drag generating devices (lift is not the main part here :). One equation to remember is quite easy in that case: Cdi (induced drag coefficient) = Cl^2 (lift coefficient squared) / Pi * AR (wing aspect ratio) Cheers!
