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.
Ultra Pup N3 Pup Single seat variant designed to resemble a 3/4 scale Piper J-3 Cub.Originally named the Nostalgair N-3 Pup. Engine is a TEC Half VW of 40 hp (30 kW).

Ordnance crest "WHAT'S IN A NAME" - military education about SNL. This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
Wag-Aero started with a line of inspection covers, then eventually a comprehensive line of aircraft parts, including a full line of parts for the Piper Cub. After several attempts to purchase the rights to the Piper Cub for new production, Wag-Aero owner Jack Wagner designed a homebuilt kit that would allow homebuilders to construct new ...
The wing main spar is a dismountable two-piece carbon fibre beam which joins under the front seat; an auxiliary spar carries the aileron and flap mountings. In plan, the leading edge is elliptical, and there is slight taper on the outer trailing edge where the ailerons are mounted. Single slotted, electrically-operated flaps occupy the rest of ...
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 ...
A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which a rotor mounted on a spinning shaft generates lift), and ornithopters (in which the wings oscillate to generate lift).
Other fixed-wing aircraft configurations may use different control surfaces but the basic principles remain. The controls (stick and rudder ) for rotary wing aircraft ( helicopter or autogyro ) accomplish the same motions about the three axes of rotation , but manipulate the rotating flight controls ( main rotor disk and tail rotor disk) in a ...
