What justifies a biplane over a braced monoplane?
The braced monoplane has similar structural depth to the braced biplane but less than twice the total wing area, so many argued in its favour. … The advantages of the biplane you mention - high strength and short span - proved to give greater manoeuvrability, stiffness and damage tolerance when it mattered, and the monoplane quickly became obsolete …

Why are/were there almost no tricycle-gear biplanes?
The biplane and tailwheel configurations are not directly related, but are both symptoms of the historical quest for light weight. … Similarly, a tail wheel is simply smaller and lighter than a nose wheel.
200-2,000 hp engines brought the monoplane speeds which the biplane could not reach and so the biplane was all but abandoned. …

Wing dihedral in a biplane
The main issue with biplanes is the separation between the planes, in relation to the wing chord. They need to be well separated to avoid interference and hence inefficiency. Anhedral lower plus dihed …

What was the lift-to-drag ratio for WWI biplanes?
AE Berriman published his respected survey of Aviation in 1913. At that time drag was known as resistance, with other terms such as head resistance or drift also used. He discusses the lift:resistance …

Would supersonic bi/tri/multiplane wings have less lift interference drag than a subsonic ve...
In the Busemann biplane the shock waves interfere in such a way as to actually reduce drag and also to reduce the sonic boom. …

Does bi-wings create essentially double the uplift as single wings?
If by bi-wings you mean a biplane then the airflow above the lower wing and the airflow below the upper wing interfere with each other and lift is lost. … The advantage of the biplane is that it is light and compact, which at slow speeds can more than compensate for the loss of lift. …

Any biplane flying wings after 1914?
The 1932 Westland-Hill Pterodactyl V was a tailless sesquiplane - a biplane with the upper wing bigger than the lower one. …
