[2] The Shirl was a two-bay biplane with foldable fabric-covered wings, without stagger and of equal span, carrying two pairs of ailerons. The fuselage was rectangular in cross-section and plywood-covered, in anticipation of ditching at the end of the mission, since deck landing was not yet practicable.
Profile drag caused by the deflected ailerons may add further to the difference, along with changes in the lift vectors as one rotates back while the other rotates forward. A 1937 Waco VKS-7 cabin-class biplane with its pairs of quadruple ailerons linked by an external vertical connector to simplify its aileron control system. The ailerons on ...
The Avro Baby was a single-bay biplane of conventional configuration with a wire-braced wooden structure covered in canvas. It had equal-span, unstaggered wings which each carried two pairs of ailerons. Initially, the aircraft was finless and had a rudder of almost circular shape. There were later variations of this.
It is a two-part aileron that can be deflected as a unit to provide roll control, or split open to act as an air brake. Decelerons are used on the Fairchild Republic A-10 Thunderbolt II , and in turn to a stabilizer the Northrop Grumman B-2 Spirit flying wing . [ 1 ]
The Potez XVIII had a conventional undercarriage with two pairs of underwing mainwheels and a tail skid. Each pair was mounted on two V-form struts with aerofoil section, duralumin forward legs and rear telescopic, shock absorbing legs. [1] [2] Only one Potez XVIII was built.
Two more pairs of struts from this point to the wing centre formed a cabane. Only the outer wing sections carried dihedral. Only the outer wing sections carried dihedral. There were ailerons on both upper and lower wings but only the upper pair were aerodynamically balanced by extensions beyond the wingtips.
[2] [3] Avro built the aircraft in Manchester, transporting it to Brooklands for its first flight on 25 May 1911. It was a two-bay single-seat pusher biplane with wings of unequal span. The outer half of each upper wing carried a pair of ailerons; the larger inner one had a semicircular trailing edge extending well behind the wing trailing edge.
It carried a pair of narrow ailerons, inboard of which were wing-folding boxes, hinged sections of the trailing edge which could be lifted up to allow the wings to fold backwards against the fuselage. All four spars were identical and the pairs of ailerons and wingboxes were interchangeable to keep the costs of spares low.
