Orlican VT-16 Orlik / VT-116 Orlik II

Let VT-16 Orlik

The VT-16 Orlik was designed by Jiri Matejček and is a high-wing monoplane of all-wood construction, except that the skin is stabilized with Umakol high-smoothness polystyrene foam. Its wing has a single spar structure with a forward torsion box; the whole wing is plywood skinned and foam filled, allowing the ribs to be comparatively widely spaced. In plan it is straight-tapered with blunt tips; there are 3° of dihedral. It has conventional plain ailerons and spoilers at mid-chord, which extend both above and below the wing.
The pilot sits under a detachable one-piece canopy, with oxygen and radio equipment as optional. The landing gear consists of a non-retractable monowheel and a tailskid. The wooden fin and rudder are both fabric-covered and the all-moving tailplane has a leading edge structurally similar to the wing, with fabric covering aft of the spar, and an anti-servo tab fitted.
The VT-16 Orlik prototype was built by some of the design staff of the Czech Republic Orlican National Works.
At the time of its first flight in August 1959 it was a Standard Class glider with a 15 m (49 ft 3 in) span. Later aircraft had 16 m (52 ft 6 in) and 18 m (59 ft 1 in) spans but it was the 16 m version that went into series production at the Orlican National Works at Chocen.

25 VT-16 Orliks were produced in the first series production run, going to Czech gliding clubs. The Orlik also set several new Czech national gliding records during 1962.
15 VT-16s and 48 VT-116s remain on the Czech civil aircraft register in 2010, though some are disassembled.
