The newer PA-12 model was initially powered by a 108 hp (81 kW) Lycoming O-235-C engine, was fully cowled, and had a metal spar wing with two 19 gallon fuel tanks. A Lycoming O-235-C1 engine rated at 115 hp (86 kW) for takeoff was optional. [2] [3]
A number of MFI-9Bs had been constructed in hopes of a sale to the Swedish Air Force, but when the sale fell through, the aircraft became available at a low price. So in May 1969, von Rosen formed a squadron of five MiniCOINs to fight in the Nigerian Civil War (1967–1970) on the side of the Biafrans in support of their effort to create an ...
Main spar of a de Havilland DH.60 Moth. In a fixed-wing aircraft, the spar is often the main structural member of the wing, running spanwise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of the wings while on the ground.
The lower wing has 3 degrees of dihedral. Ailerons are of the Friese type, with two ailerons on the lower wing standard and four ailerons optional. The front wing spar was initially a 3 in (7.6 cm) aluminum tube and the rear spar is "C" channel. Starting 1 January 1989 the front spar was changed to a rectangular spar and an outboard drag brace ...
The Berkut is derived from the Rutan Long-EZ, with the primary differences being retractable main landing gear, dual canopies, and molded fuselage, strakes, and wing spar. Like the Long EZ, the Berkut carries two people in a tandem seating arrangement. The front seat occupant has access to all instrumentation and controls.
The aircraft fuselage is made from welded 4130 steel tubing, while the wing is of all-wooden construction, with all surfaces covered with doped aircraft fabric. Later models have an aluminum wing spar. Its 35.50 ft (10.8 m) span wing employs a custom Mason airfoil, mounts flaps and has a wing area of 177.3 sq ft (16.47 m 2).
The Mite is constructed mainly of fabric-covered wood, with a single spruce and plywood "D" wing spar. The wing aft of the spar is fabric-covered. [2] The airfoil selected for the design was the NACA 64A215. [3] The M-18 represented the first time a NACA 6-series airfoil had been used on a civil aircraft after World War II. [1]
The landing gear may be configured as fixed, or retractable, in tricycle or conventional layout. [4] The wing uses a single box spar covered in 3/32" plywood leading edge skins. The entire wing is fabric covered. [5]
