How Does a Triplane Work?

A triplane arrangement has a narrower wing chord than a biplane of similar span and area. This gives each wing-plane a slender appearance with higher aspect ratio, making it more efficient and giving increased lift.

Why did planes have 3 wings?

In theory, the shorter the fuselage was, the quicker the maneuverability would be in pitch and yaw. Dividing the wing area into three parts also allowed the wings to be constructed with a shorter span, which increased the rate of roll. Smith also designed it with ailerons on all three wings to increase maneuverability.

Why did ww1 planes have 2 wings?

The main reason for having multiple wings in the initial years of the aviation was the lack of availability of materials with sufficient strength. The main advantage of the biplane is that the wings could be shorter for a given lift.
