Bomber IL-22

 

Four-engine bomber was developed in 1946, the aircraft was not made. Powerplant: four turbo-jet engine TP-1 1300 kg of thrust.

In 1947, the start of the existence of the bomber jet rocket aviation was launched. In June of this year, under control of V. Kokkinaki, a four-engine bomber Il-22 was launched into the air. This event was very significant, given the fact that the aircraft was equipped with domestic motors of A. Lyulka's design - TR-1. It was not possible to reach the calculated drafts in 1600 kgs, they remained within 1300 kgf. Because of this, the take-off mass of the car was limited by the weight of 20 tons instead of the 24 planned. The range of flight was only 865 km, flight time - one and a half hours. The speed of flight at the ground was 656 km, and at an altitude of 718 km.

Takeoff aircraft IL-22 on takeoff was over 1,1 km, but for the first jet bomber were all the flaws are forgivable because of similar size unit was tested for the first time.

Nevertheless, the plane received good reviews from test pilots. Based on the words of Kokkinaki, the car responded perfectly to the management teams. One of the outermost engines succumbed to throttling, but it is easily leveled by deflecting the steering wheel or steering wheel. The aircraft has a large volume of fuselage, but it is not difficult to plant a car even with a strong side wind. All you need to do is align the machine by roll. Il-22 had good aerodynamic properties. The lack of engine capacity was planned to catch up in subsequent upgrades.

What was the purpose of bulky ILYUSHIN bomber? Experimental aircraft became the basis for the research problems of heavy jet aircraft, and on its basis formed a fundamentally new concept of production aircraft.

During the construction of the aircraft has been involved a lot. Especially it concerns the issue of placing the engines, the chassis and the circuit layout of the fuselage.

Having analyzed a number of options for placement of power plants on the plane, the creators came to the decision to create the IL-22 original layout engines. Jet engines of the aircraft placed in isolated pods on wing pylons, which are relatively wing leading edge were badly brought forward.

According to the last test of such an arrangement of jet engines it was aerodynamically efficient than that of their foreign counterparts of the time. It gave less drag than the batch layout. Plus, in the case of such an arrangement to the engines easier access for repair and maintenance.

The unusual layout and became the fuselage. The cross-section had a longitudinally-oval, which solved a lot of layout tasks. The large width of the fuselage allows you to put in a crew of five: two pilots, two gunners and navigator-bombardier. The entire fuel supply was located in three soft fuselage tanks.

In the front part of the fuselage were niches for cleaning the nose landing gear.

Compared with Western counterparts ILYUSHIN decided to equip Bomber defensive weaponry to complete the program. To do this, we invented a completely new approach to the construction layout of shooters and defensive weapons, given the remote control system. The sight and weapons were directed at the target scheme t. N. "Wheatstone bridge". Moving weapons anticipate and accommodate changes perspective.

The composition of defensive weapons included three mobile cannons B-20-E with ammunition for each 400 shells and one fixed on the NA-23 150 shells. Fire from the last gun could carry out through the ring sight crew commander.

In the second stage of factory tests aircraft checked for overclocking with two solid rocket launching SR-2. They hung symmetrically to the longitudinal axis of the fuselage on the left and right sides. The flight was made in 1948 running V.Kokkinaki pilot, and it was the first in the Soviet Union, the rise of a heavy bomber, the carrier rocket.

Nevertheless, studies for the establishment of this apparatus further used for the design of new models, including famous Sukhoi IL-28.

IL-22 only the second photo. On the other three mud-28.

Excellent liner! A lot of emotions! Very pleased.

Oh, I flew once in this old gentleman. Very reliable. Look at it on the keel fairing and how many antennas on the back. Respect and uvazhuha!
