The secret about biplanes | The reason why they don't fly anymore

Biplanes look cool, but they have a story, they still exist today, and they are a curious flying piece of machinery. In this video I'll be showing a basic explanation and a short story about these airplanes.

Excellent video! As an aerobatic pilot and former biplane owner, I mildly object to your statement that biplanes are inefficient. Efficient compared to what mission for the plane? In Aerobatics, the high drag is helpful when you need to slow down quickly for an upcoming maneuver, and with the top wing set up to stall at a different rate from the bottom wing, it is much easier to control the break, as when performing a spin or a snap (flick) roll. Having said that, for the vast majority of flying purposes, you are indeed correct.

One industry in which biplanes are still common: crop dusting. The ability to fly at low speed is a big advantage here, as you're attempting to hit targets on the ground with high precision from a very low altitude.

They have excellent stall characteristics because of their lift to weight ratio, which is why they're still the best for tight aerial maneuvers at low speeds. With more powerful engines plus a hundred years of structural improvements, we've got some killer performing biplanes now. Granted they're normally air show/hobbyist builds, they've still got a place in the aviation world.

Friend of mine while flying one of these old things called a tower to request a ground speed estimate because the head wind was getting bad. They said they didn’t have his ground speed but the car’s below are passing him. He set it down and took a break.

The thing is about the extra lift means you can have shorter wings, Shorter wings means better roll which means getting into a turns faster, using your elevators( bigger surface area)instead of your rudder in dog fights .

Sure, they're inefficient for some applications but great in others. Many years ago I was driving my 1930 Ford Model A to the Street Rod Nationals in Memphis, TN. Cruising up beside me was a PT-17 Stearman crop duster that was landing on a dirt strip parallel to the highway. The pilot looked at me as I watched him; two vintage machines from the same era moving at the same speed, about 70 mph. (The model A had a modern V-8 in it.) It was a very cool experience to see the vintage Stearman land right beside me from my vintage street rod. Doesn't have much of anything to do with the video but you made me think of that great experience.

I love that you mention bi-planes being held as relics of the past while showing a Pitts Special at an

_...they don't fly anymore_

I have a beautiful book from the 1920s that declares single or double wings have not yet been decided.

Biplanes aren't common today because their structure increases drag...
Biplanes used two wings because they provided extra rigidity in their design given the materials they had to work with.

[savagebolt]

Two of the best days in my long life were an aerobatic flight in a Stearman, and a lesson in a WACO.

Tail dragging, stick & rudder, radial engined biplanes are my favs.

At the moment you might be thinking that the effort for only a few thousand people is too much, but I love your videos. Soon YouTube will put you in a recommended list somewhere and then your channel will take off as long as you maintain the amazing videos you are already doing! Trust me, you are one of the examples of how people don't upload garbage to YouTube and make millions of views. The quality on YouTube takes a bit to be noticed but it pays off! Thanks again for allowing us to see such well made videos. 👍

Fun fact - the Wright brothers had a business building bicycles. Their racing model was called "The Flyer". They named their successful aircraft after their bicycle.

In the RC world bipes are gorgeous planes and LOTS of fun to fly. Due to the relatively short wingspan they are usually more responsive than two-wing planes. So the snaps are snappier, the roll-rates faster, and the tumbles quicker and longer lasting. And they just LOOK cool! The biggest downside to rc bipes is they take longer to set up and break down, which is why most rc guys don't fly them (though rc manufacturers are now producing bipes that are designed to be easier \ quicker to assemble at the field). But, to me, the extra set-up time is well worth it (though only bring a bipe to the field when I know I'll be there all day). I love my bipes!

Living by an airfield that does acrobatic displays, I have to admit I see biplanes weekly, so they’re certainly still flying near me haha

[hondaxlk]

If I was given a choice of what plane I wanted. I’d pick a biplane every time. Style and beauty

AN-2: " How you doin' "?

I have been thinking recently about the firefighters using old surplus, repurposed aircraft which have deteriorated, resulting in several fatal crashes. In a couple of cases the wings literally broke off from corrosion of the spars. The response to this more recently is to upgrade to old jet airliners like the DC-10 to carry water and fire retardant but obviously for the purposes of firefighting they are not ideal. Their biggest advantage is large capacity. This led me to imagine a special built aircraft for this purpose, which requires heavy lifting, great structural integrity and maneuverability. Why not take advantage of these properties of the biplane configuration, where strength and maneuverability are its advantage? A modern, large modern air tanker of biplane configuration seems ideal to me. The disadvantage of high drag is not a big issue because slow flying is another feature desired for firefighting.Power it with turboprops, which do better than jets low and slow, and the economy will be even better.

Thank you for posting this video. I learned something.
