Yakovlev UT-1


In the first half of the last century, Yakovlev Design Bureau are widely pursued designing training aircraft, one of the first aircraft UT-1. These machines are designed for pilot training or to improve their skills. In addition to peaceful applications, these machines during World War II was also used as a martial after setting them guns or bombs hanging. It was a small attack.

Year: 1931

At the beginning and middle of 30-ies of the last century, pilots were trained on Y-2 planes that they were provided with air clubs, the most popular of these was the club Osoaviakhim. These double unit provides the opportunity to learn the basics of piloting, but has been slow. It is because of the lack of speed of designers started to create more high-speed and light aircraft, which became the UT-1.

This unit is a cantilever monoplane, which had mixed structure construction. This machine is operated by a single pilot and was equipped with a single open cockpit. Before it was installed wind visor. Landing gear was fixed gear type.

The fuselage of the machine was introduced welded farm, which was made of steel pipes thin section. On the outside of the building it was equipped with wooden frames, as well as for better aerodynamics - stringers. As for the sides and bottom of the machine, they were covered with canvas. But the nose portion was made of steel, the entire space of the cockpit was made of plywood. The engine compartment units have been established such as the oil tank and two fuel tank. Dashboard pilot and his seat, too, were made of wood, with the back of the chair was placed a parachute.

The wings were made of two side members and are non-releasable. The side walls have a box-like appearance. It is necessary to specify that all parts of the wing are made of wood, only the rear part of the aluminum was in its construction.

The power plant was represented by a five-cylinder air-cooled engine of the M-11 class. He could develop the maximum power, which was 100 horsepower. Some aircraft of this type were equipped with more powerful engines such as M-11G, which had 115 horsepower. The screw of the device had a fixed pitch and was equipped with two blades, which were also made of wood. The hood that was installed on the UT-1 aircraft covered only the crankcase cover of the engine, and the cylinders had no covers, this helped the best cooling. The engine was started manually by turning the screw.

A large number of tail unit was made of aluminum, with the exception of the car sides. In order to increase the strength and rigidity have been installed braces, which connect the keel and stabilizer. Wiring, which provides control of the elevators, was made in a rigid form, and to the direction of handlebars fastened soft wiring.

Chassis aircraft UT-1 was represented by three pillars, which were pyramidal structure, consisting of, fork type. The rear pillars and struts were attached to the wing spars. To provide a softer landing racks were fitted with rubber inserts and plate absorbers. gear wheels were equipped with aluminum fairing and had no brakes. In cold weather, the wheels can be replaced by a ski-type landing gear.
