Yak-14 is a metal glider landing. The construction scheme of performance - strut-braced high. The design is applied with a single-spar wing profile of Clark Y. The central part of the wing is sheathed blade and the toe - duralumin. The ailerons and flaps are divided into two sections, and are placed around the wingspan. The spoilers are made of duralumin plates are on the trapezoidal wing portions.
The fuselage of hromansileevyh pipe truss. The middle part has a cross-section and is used as a cargo compartment, the dimensions of which - x 8 2,3 2,3 x m, and the volume - 42,5 m ³. Below average laid two truss beams welded together. Their role is in the perception of loads transported goods produced. The first series gliders got floor plywood 10 mm, and in the next series in the casing of the floor began to use duralumin sheets.
Above the floor drains were laid, which was carried out rolling self-propelled guns and armored vehicles during loading or unloading. If you needed to carry the composition of the landing, stairs removed and in their place put the seat. Seat backs for paratroopers touch the sides of the fuselage and placed around the perimeter of the cargo compartment. On the left side there is a door that serves to escape landing glider. In a series of airframe manufactured after 1951 city, to this end it has been made yet another door to the front of the fuselage on the starboard side.
The control cabin is located on the cargo bay and to improve visibility somewhat shifted to the left side. To get into the cabin through the door from the outside can be located on the left side of the cargo compartment - through a hatch in the ceiling.
Also on the right side of the cockpit was located a small door, which could be reset for emergency escape glider.
Fuselage is made of cloth, fixed to the longitudinal and transverse the frames herringbone tape.
Single-fin vertical tail glider. Its frame is made of duralumin, plating - from the web.
Chassis tricycle with a support on the nose wheel has an oil-pneumatic shock absorption. The main brake wheels are sized - 900 h300 mm. Self-orienting the nose wheel sizes - 600 250 x mm.
To facilitate loading of equipment, as well as during the landing on skis was carried out in a pressure relief dampers landing gear. When this procedure was performed on earth, according to eyewitnesses, the glider became like a camel, who was preparing to take riders. After opening the air valve, first squatted basic right landing gear, then the nose wheel, and after it - the main left. So "vraskachku" Yak-14 falls below the starting position on 450 mm. In preparation before takeoff, landing gear shock absorber back pressure is raised to the required operational values. This is carried out using only on-board air system without involving the help of external pumps.
In serial production glider suffered about a hundred changes. The most significant were: replacement of the landing bow lights FS-155 more powerful FS-240, equipment cabin floor, wing fillets and a cargo compartment system further drainage (in fact, just to make new holes for rainwater drainage), equipping gliders with removable seats paratroopers, cleaning Glazing in the bow portion of the lower face. Most of these changes were introduced after 1951 city
Towing a glider Yak-14 conducted Il-12D and IL-12T. Cable, which is used during the towing, had a length and diameter of the 100 14,5 m mm. Reserve fuel from IL-12T enough to provide a range of throwing glider 495 km. During towing using IL-12D tactical range was 340 km.
As part of the on-board equipment Yak-14 was radio RSI-6K on which the pilots to keep in touch with air facilities and ground stations. At the height of 1000 m signal range of the device was 150 km.
After the uncoupling of the optimal speed was planning mark 140 km / h. When planting in the dry grass path speed unit on wheels was 380 m skiing - 270 m. If the grass cover was wet, the amount of run on skis increased to 480 m. Perform landing on skis in the latter case is not easy, because the pilot can not use the brakes and slide the glider on a dangerous surface. And when it came to mass landing gliders, it was hard to hold a safe taxiing after landing. If the landing took place on the powdery snow, or plowed, missing the landing pad size 300 70 x m with an open approach. The glider Yak-14 6750 full load kg can be put on svezhevspahannoe field. The length of the path during this landing was 75-140 m.
