RE: Largest Bi-Plane ever built.
Wow. Thats a huge bi-plane there. Very cool. Pls can i ask, what were the advantages of biplanes??i mean they were structurally more complex, had more drag and many things, then why the earlier flying machines were biplanes?? what made them more advantageous in earlier times?? was their only purpose was to provide more lift?? if so, why aren't they used now(i mean, in air not in meuseums
Okay from my little experience about planes and living nesr an airfield, i can say that you get (almost) twice as much lift for a given wingspan. It was difficult to create long wings that were stiff enough to support themselves and the aerodynamic forces. Biplanes not only give you shorter wings but you can easily brace them against each other. The problem as you pointed out is that they are complex and give lots of drag. Some are used today, tandem wings (with one wing in front of the other) or canards (small wing near the nose) - they are more manouverable and usually don't need horizontal tails.
I think from my level of knowledge. Yes, the canard has a higher angle of attack than the wing and stalls first, this pushes the nose down, increases the speed and automatically recovers. I'm guessing also that since the canard isn't in the wash of the main wing the aerodynamic controls on it are more effective than on a conventional tail.
I agree with @lucyogo.
As far as I can remember (and it's been a while), the main advantage to canards is that they lower the stall potential for the main wings. You can have a steeper angle of attack at low power without falling down. The elevators don't counter lift; they simply change the pitch axis of the aeroplane. You get the same effect with elevons on a delta layout, which doesn't even have a 'tail'
Higher uplifts, especially at low speeds (and in the start, with heavy weight ~10PS engines didn't make that much speed).
You can also do really close corners.
That is also why you sometimes had triple wings.
Hello, A biplane has extraordinary abilities to fly at low speed and perform takeoffs and landings over short distances (STOL)
