E-150 fighter even its external appearance is seriously different from all previously built aircraft. The car was a midwing having a delta wing and fuselage, wielding a circular section. The fuselage is more reminiscent of a pipe that had virtually uniform diameter throughout the length of their own. The aircraft had a delta wing of low aspect ratio, the aerodynamic characteristics of which were already fairly well studied in the past experienced fighters E-4 and E-5 wing had swept across the front edge of 60 degrees. Cast cockpit canopy drop-forward and upward, he did not have a windshield and pretty smoothly passed into fairing, which extended to the bottom of the keel. Glazing cockpit canopy was made of special glass T2-55 in the width 12 mm. This glass can withstand aerodynamic heating temperature within 170 ° C.
The air intake diameter of the huge aircraft included a central body in the form of a cone. With all of this in the forward fuselage of the fighter mounted "multi-hop" cone made of a dielectric material, the cone is composed of 3 stages. It was the radar antenna "Hurricane-5B." This radar had a long-range detection of air targets and can operate in a review, also in the mode of target tracking. Radar "Hurricane-5B" was associated with a receiving telekomandnoy system and fire control system, and autopilot controls. Interaction of 3 of these devices provide a performance of the aircraft from the ground guided automatic flight in a given area and next to that target acquisition radar signals and execute attacks at any time of day and in all weather criteria. Attack the target was carried out after combining the objectives Tagged with radar scope interceptor.
To improve the Putnam resistance fighter at supersonic flight speeds under the fuselage in the rear installed aerodynamic ridge. Also at the bottom of the fuselage fighter placed 3 airbrake. In order to reduce the length of the path of the aircraft after landing drag chute was used PG-5605-58 a total area of 18 sq. m. meters. On the underside of the wings of the fighter-interceptor provided for the installation on one pylon, who served for the suspension of guided missiles "air-to-air."
Fighter-Interceptor E-150 was designed for operation at a speed of about 2,800 km / h at an altitude of 20-25 km. With all of this engine aircraft P-15-300 was intended from the outset to test for unmanned aircraft and had a very small because the flight resource. This TRD could develop the highest traction in 6840 kgf and afterburner thrust increased to 10 150 kg, slider equipped with a special ejector, which allowed him to show the total traction in 19,800 kg at a speed of the airplane M = 2.4-2.5, except that it significantly reduced the resistance of the bottom. Because of the high aerodynamic heating fighter flying at tremendous speeds, the most heat-stressed elements of its construction it was necessary to be made of heat resistant materials (eg stainless steel). Fuel System E-150 fighter according to the latest version of draft design includes 5 Myagenko fuselage and two wing fuel tank. Common in store fuel fighter was 4750 liters.
By September 1958 was built the first prototype of the fighter-interceptor E-150. Then in the car for 6 months passed testing ground. Then, before the middle of 1960 to a high quality motor cars, so that only 8 July AV Fedotov design bureau's test pilot for the first time took the machine into the sky. From that day or industrial test cycle lasted fighter, which ended January 25, 1962. During test flights from 21 January to 30 March 1961 reached a speed fighter of M = 2.1, and the highest altitude — 21,000 feet. After that, the fighter had to replace the engine, after the substitution of the E-150 engine produced 20 more missions. In the 28th flight the aircraft was able to reach the maximum speed of 2,890 km / h (M = 2.65) at an altitude of 19,100 feet, with all this at the motor was still in store traction. Take-off weight of the fighter-interceptor in this "record" flight equated 10,175 kg. The larger the ceiling, which was able to reach a fighter E-150 on the tests amounted to 22,500 meters.
It seemed finally spice OKB-155 managed to make a fighter that was so necessary to Russian air defense system. But the main obstacle in the way of engine designers began to P15-300, which had a small resource. Resource was quite alone for ground and bench testing with the following setting on the plane to make a single flight. At the same time, the mass creation interceptor could be started only with a reliable engine and exhaust. That's why the line was continued interceptor aircraft engines E-152.
The performance properties of the E-150:
Dimensions: Wingspan — 8.44 m, length — 18.44 m
Wing area — 34.62 square meters. m

E-152 — Russian pilot fighter-Interceptor made by the OKB-155 mi. Mikoyan. The plane was designed to intercept and eliminate enemy planes, soaring at speeds up to 1600 km / h at an altitude of 10,000 meters and at speeds of up to 2500 km / h at an altitude of 20,000 meters on vstrechnoperesekayuschihsya courses. There were built two prototypes of the fighter E-152 and E-1-152-2, and 1 copy of the E-152A, which equipped with with 2 R11F-300 turbojet engine. On the basis of complexes interception, which have been worked on experimental fighter E-150, E-152, E-152A, was created in the upcoming serial fighter-interceptor MiG-25, which in the long years was the best car in its class.
The experimental fighter-interceptor E-152 came into existence as a result of cross-breeding of experimental aircraft E-150 and E-152 A, intended for testing motor P-15-300 and testing of the automatic target interception "Hurricane-5B", as the new SD K-9 . Taking into account the advice of test pilots AV Fedotov and GK Mosolov, on the new fighter was improved Putney stability, reduced unit load on the wing, the ailerons eliminated vibration and shaking wing tips. It was created a new wing, which holds a larger area that has been achieved through the introduction of higher end of the chord, which provided for the suspension of great firmness guided missiles. Aircraft nose cone was a three-step, as in E-150 and motionless. Based on a cylindrical nose cone was mounted perforated zone, which served to drain the boundary layer in order to increase the total pressure recovery coefficient in front of the compressor. Ejection system to anticipate the pilot's canopy protection. The main element of an emergency escape vehicle pilot was katapupltirumemoe chair SC-2.
Configurations that have occurred in the design of an airplane wing, have allowed increment track chassis, which in turn assist to make better machine stability during maneuvering on the runway. Putney re
sistance fighter-interceptor was improved by the extension of the chord of the keel, as the growth area of ventral ridge. In the lower fuselage E-152 was one brake plate, and in the rear fighter housed braking parachute container, the same as E-150.
All the control surfaces of the aircraft had a hydraulic control. The hydraulic system operated by the slurry AMG-10 under the pressure of 210 atmospheres. First installed on a fighter engine P15-300 could develop traction in the highest mode at up to 6,620 kgs, and in the mode Afterburner — 9935 kg. Like the E-150, E-152 fighter was equipped with an ejector for rapid short-term growth traction. Fuel is a 6-fuselage, as the front and rear wing tanks. Total aircraft fuel in store was 4,930 liters., For all that can be installed under the fuselage of an additional fuel tank with a capacity of 1500 l ..
The main equipment fighter included: automatic radio ARK-10 "Inhul" VHF RSIU-5 rangefinder SOD-57MU, autopilot AP-39, the defendant SRO-2M "Chrome", on-board equipment of the "Twister" radar " CP-1 ", a number of other devices. Fighter armament included two missiles K-9-155 launchers which were located on the wingtips of aircraft.
First built interceptor from the E-152/1 at the test airfield arrived March 16, 1961. During the first flight in the nose of the aircraft was assembled temporary centering a weight of 263 kg in. First time in the air plane raised test pilot GK Mosolov. With all of this fighter tests often stopped due to a problem in the power plant. The fighter had to change 5 engines, but neither one of them was not quite reliable.
Despite this, the pilot fighter E-152/1 was found three global record:
October 7, 1961 test pilot AV Fedotov, set a world speed record for driving on a closed route length of 100 km. The average flight speed was 2,401 km / h
July 7, 1962 test pilot GK Mosolov by plane set a world speed record. On the basis of dimensional 15-25 km. a 2-way managed to achieve an average speed of 2 681.7 km / h, with all this in one of the approaches fighter managed to develop a speed of 3000 km / h
September 11, 1962 as a test pilot PM Ostapenko set a world altitude record level flight, which amounted to 22,670 meters.
The performance properties of the E-152:
