Mignet Pou-du-Ciel - Design

Design

Mignet made the aircraft intentionally simple. The Flying Flea is essentially a highly staggered biplane, which almost could be considered to be a tandem wing aircraft, built of wood and fabric. The original design was a single-seater, and had two-axis flying controls. The aircraft had a standard control stick. Fore-and-aft movement controlled the front wing's angle of attack, increasing and decreasing the lift of the wing. Because the front wing was located forward of the center of gravity, that would pitch the nose up and down.

Side-to-side movement of the stick controlled the large rudder. This produced a rolling motion because the wings both had substantial dihedral, through yaw-roll coupling. The rudder had to be quite large not only to produce adequate roll but also because the fuselage was very short, reducing the leverage of the rudder. The Flying Flea, being a two axis aircraft, could not be landed or taken off in substantial crosswinds. This was not a big issue when the aircraft was designed because at that time aircraft were usually flown from large open fields allowing all take-offs and landings into wind.

Mignet claimed that anyone who could build a packing case and drive a car could fly a Flying Flea.
