Detailed data of MIG-15 fighter.
The initial development of MIG-15 fighter photo appreciation (20 photos) was not smooth, but it was always impossible to test flight due to engine technical reasons. It was not until the British Labour government agreed to sell two British-made centrifugal jet engines that a breakthrough was made. First flight in June 1947. The first prototype was destroyed on the first landing because of its rough construction. The second prototype was redesigned, and the first flights of 1947 and 65438+were successful in February. 1948 was put into production in June and became the main fighter of the Soviet Air Force. In the early production batch, the British Nien engine was used, and in the middle and late stage, the domestic RD-45 engine copied from Nien was used.
MIG-15 adopts nose air intake mode. Above the fuselage is a bubble-shaped canopy that ejects the seat. At the nose, the airflow is divided into two streams by the partition of the air inlet. The wing is located in the middle and front of the fuselage, with a sweepback angle of 35 degrees. There are four wing knives, and two auxiliary fuel tanks or bombs can be hung under the wing. Therefore, MIG-15 is the first practical swept-wing aircraft in the Soviet Union, which has taken shape as a modern jet. The wing runs through the fuselage, and the partition in the inlet divides the airflow into four streams. A certain amount of lead is placed at the leading edge of the wing to reduce the requirements for the torsional stiffness of the wing. The plane is not equipped with radar and does not have all-weather combat capability.
