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.
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).
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]
There are two main wing configurations that can be built. An aluminum wing spar with hinges allows the wings to be folded for trailering or storage. A wooden wing spar configuration gives the plane a lighter weight, but leaves the wings fixed. The engine cowling is made from fiberglass. [3]
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 ...
Data from Jane's All the World's Aircraft 2011/12 [2] Skyleader 100 Single-seat variant, with optional rectangular or trapezoidal wing planform and powered by a 64 hp (48 kW) Rotax 582 two-stroke engine. Was expected to be marketed starting in 2011 as a kit or complete aircraft. [8] [9] KP-2U Skyleader 150 Originally called the Kappa 77 KP-2U Sova.
A fixed-wing aircraft may have more than one wing plane, stacked one above another: Biplane: two wing planes of similar size, stacked one above the other.The biplane is inherently lighter and stronger than a monoplane and was the most common configuration until the 1930s.
The aircraft is constructed with fabric covered 4130 steel tube structure and spruce wing spars. Ribs are plywood with cap strips. ... Wing area: 140 sq ft (13 m 2 ...
