The Sharapov-Verzilov “Piervieniets” (First) (Russian: Шарапов-Верзилов “Первенец”) was designed as a single-seater training glider.
Conceptually the “Piervienets” was designed as a high wing glider braced by four uprights. The wing had a rectangular shape in the plane with ailerons in the outer area.
The fuselage was in the form of a low-sided “bathtub” to which a flat, uncoated wooden structure was attached, ending in the conventional tail.
The landing gear consisted of two wheels located on the sides and a tail skid.
The pilot sat in a fully exposed seat. The cabin space was so wide that flights were carried out with a passenger behind the pilot.
Built in Simferopol in 1927 by AN Sharapov and VN Verzilov and flying that fall, the “Piervieniets” glider was entered in the IV edition of the national glider competitions. During competitions it was the most popular glider, flying 274 training flights.
