The “Pavel Golovin” glider, also known as PAI-2, was designed and built by a group of enthusiasts consisting of BN Sheremetiev, Yu. I. Koltunov, BL Sirken and AI Pietsuj. The main objective in the construction of this glider was the study of the flight methodology for a training glider with a view to using it for the calculation of record-keeping flights.
The Sheremetiev / Koltunov / Sirken / Pietsuj “Pavel Golovin” glider (Russian: Шереметев, Колтунов, Сиркен, Пьецух – Павел Головин) was designed as a cantilever monoplane with high wing in parasol. The wing construction was characterized by a single spar.
The fuselage was constructed of wood and featured a hexagonal cross section.
In order to provide the pilot with the highest level of comfort, a large cockpit was designed, equipped with all the necessary instruments: altimeter, speedometer, barometer, thermometer, compass, reversal indicator. The cabin was closed using an angled cover, which opened to the side and could be released from the inside in case of emergencies.
The tests carried out in July 1937 with the pilot II Shelest at the controls, showed good stability in the air and response to the controls, as well as excellent manoeuvrability. At speeds of 80 – 160 km / h it was possible to make high school piloting figures.
The negative aspects were the long take-off run and the large wing loading. The landing, on the other hand, was quite short.
