MiG-5, or long-range escort fighter DIS-200, - This is a single twin-engine (engines AM-37) fighter aircraft, which is designed to support tactical bombers.
In early October 1940 years NCAP reviewed the draft project provided long-range fighter and approved it. People's Commissariat of DIS-200 recommended to be built.
In November of the same year they adopted the layout of the aircraft, but recommended some changes to the design. After examining the sketch and layout fighter included in the "plan of experimental aircraft" on 1941 year. Official NCAP task in accordance with the EPPP-41 sent to the JCE (Experienced design department) plant №1 Aviakhim name. Under the rules of the job we had to design and build three variants of the aircraft and to detach them on state tests.
The main tasks of the aircraft DIS-200 were:
maintain support tactical long-range bombers;
if necessary to ensure a breakthrough of enemy defenses;
at different distances from the location of the patrol to make the action;
conduct military reconnaissance behind enemy lines;
the ability to use as a torpedo or dive bomber.
The design of the MiG-5. Weaponry
MiG-5 is a two-meter Single nizkoplanom mixed construction. The chassis is removed, and the tail feathers explode. The design of the airplane consists of several major parts. Because of this it is much easier to transport undertaken.
The fuselage consists of three units: the bow - duralumin, medium - wood monocoque and tail - farm, constructed from steel pipes, siding duralumin.
Dvuhlonzheronnoe wing center section has a metal and wooden console, but the sock is made of bakelite plywood. Made from duralumin plates, flaps and slats. Aft fuselage ends with wooden tail control fins. The cockpit controls are presented ailerons and elevators and directions. Recently constructed of duralumin frame and fabric covering.
By gooseneck chassis attached maslopnevmatichesky shock. In the presence of three wheels. On the main landing wheel set 1000h350 mm in size, which were removed in the nacelle (located on the center). The tail wheel supporting structure and has a size 470h210 mm.
For this kind of fighter developed a special weapon system. With ammunition from the 200 300 shells easy to type on lёgkosёmnom carriage placed a 23-millimeter gun MP-6. It is placed in the nose of the fuselage. Two copies of a large-caliber machine gun BS 12,7 mm ammunition from the 300 600 rounds to four light machine guns caliber ShKAS 7,62 mm ammunition rounds to 1500.
Initially, engineers planned to install a gun-23 load cells, but experts from the Air Force and prototyping Commission decided that the MP-6 will be more effective.
In one modified variants considered the possibility of replacing guns on 1000 bomb weighing one kg or torpedo parachute. It is also exploring options for the installation of two jet guns RO-82 82 mm caliber that shoot "rockets" (unguided solid-rocket powder) and are used to protect the rear hemisphere. Two gun MP-6 already established during the aircraft design. Ammunition each of them - 120 shells light type.
The first prototype of the future MiG-5
When finished state tests of the aircraft, the plant №1 Aviakhim received an order to halt construction of single-engine fighter and-200 and early construction of the twin-engine DIS-200. The order entered on Oct. 1940 years.
But-200 did not want to close its production is simply transferred to the plant №21. For factory testing new aircraft order of the designated lead test pilot A. Ekatova. Also in March 11 41, was selected Lead Engineer - A. liar. Unfortunately, 13 March A. ECAT died. It was necessary to choose a new pilot. By order of the NCAP (May 1941 years) it became Zhukov. 11 June this year, the MiG-5 made its first flight. The whole period of factory flight tests took a small amount of time. He was held in the period from the first of July to October 5 41 years.
Modification and testing of second instance
When the received information in the KB to terminate the development of MP-6 gun and replace it with a load cell-23, designers realized that this action will result in a large number of alterations of center. It is because of this strike weapons in the test did not even brought.
Also from the beginning of the MiG-5 established a three-bladed propeller AV-5L P4 with 3,1-meter diameter. When the determined maximum speed adjustment, the air unit has reached a point of speed 560 km / h at an altitude of 7500 m. However, the result was less than planned in the 104 km / h.
We decided to use chetyrehlopastnym screw AB-9B-A-149 three-meter diameter. It also differs from the previous model, the presence of the wing pressed to the convex portions of the exhaust manifolds, a modified form of the suction pipe and the installation of a wing of the exit tunnel oil cooler. Due to the speed of the aircraft increased to 610 km / h at an altitude of 6800 m. For the climb 5000 m aircraft need only 5,5 minutes.
As planned, the plane would produce a standard factory №1, but factory tests confirmed the fears of future LII defects that are not strictly recommended to produce it in series. But further tests were carried out as EDO and other aviavedomstvam their results were needed for the construction of future fighters.
