Yakovlev Yak-38

 

Yak-38 is a carrier-based attack aircraft of Soviet production. It was the first aircraft in the Soviet Union, which had an opportunity to make a vertical takeoff and landing. This product during manufacturing is also designated as the product 86, and in NATO code, he received the designation "Kznets." The basis of this machine was taken many constructive features of the previous Yak-36.

At Yak-38 was set up-and-sustainer motor of the type P-28 and two engine lifting type designation RD-38. All this was taken directly behind the cockpit. This unit was the only one in the Soviet Union, which was equipped with an automatic ejection, ie automatic machine to decide when it was necessary to produce the pilot bailout. Attack aircraft Yak-38 serially produced for fifteen years, since 1974 years. During that time, it was built 231 car of this class. Engaged in serial production of an aircraft factory in the city of Saratov. This device is widely used on aircraft carriers of the USSR.

History of the attack aircraft Yak-38

Stories he is closely connected with the creation of the previous Yak-36, because many units were used precisely with the machine. Attack aircraft Yak-38 produced its first flight in 1970 year. In the future, the pilots were working on technology take off on short distances, the first test of these indicators reached YI Churilov. In addition to carrier-based, the aircraft used in military conflicts over land. Thus, in 80, four of the unit were sent to support our troops in Afghanistan. These machines perform combat missions for four months, while one has been lost because of technical reasons.

The machine did not have much success with the sailors, and its not really like to use on aircraft carriers, due to the fact that it had insufficient thrust-marine applications. Also drawback was the fact that at high temperatures and high humidity the aircraft had almost constant problems with take-off, and he had a short range.

Yak-38

When operating this machine has become a leader in the number of accidents and loss of life. Pilots only saves automatic ejection system. At the end of the year 89 this unit ceased to produce, and all the planes were transferred to the land base, and after a while they are generally removed from the Air Force. With 2004, data stormtroopers were deposited.

It is worth noting that in 85 by members of Yakovlev Design Bureau has created a qualitative modification of the Yak-38M, which had the highest performance. Lockers In this model, it was found two PTB and was strengthened combat power of the machine. On the basis of the Yak-38 planned to create a fighter, which was placed on aircraft carriers. Here, designers planned to increase the area of ​​the wing and equip cars more fuel tanks. Ultimately, these projects have remained only on paper.

Design features of the Yak-38

The plane is made in the scheme cantilever mid and is an all-metal construction. As the base metal was taken aluminum and its alloys, titanium is also used, thereby reducing the weight and strengthen the entire structure. Some parts are made of hardened steel alloys, and antipyretics.

Onboard equipment unit provides the possibility to use the attack in almost any weather conditions and at any time, on land or ship takeoff sites. The on-board equipment included such systems: the control unit ACS-36, navigation system at close range such as "Square", the two units heading reference model SCR-2. Besides all this, using standard devices such as radio compass and altimeter.

The cockpit was equipped with a large number of devices, which served as a pilot to better combat activities. On the dashboard was placed flight director type CAT-1273, altimeter and speed indicator device. On the panel were derived indicators pilot gas temperature, the amount of fuel and oxygen, as well as the standing of the engine speed sensor.

To carry out fire blow Yak-38 was equipped with a new model with an optical sight ASP-PFD-21. For guided missiles X-23 the machine was installed hanging device "Delta NG2." For identification of the unit was the state system "Chrome". To contact the pilots used the intercom and radio class P-863.

As for the combat capabilities, here it must be said that this machine is able to carry out an attack on both surface and ground targets and an effective air combat. The device allows to perform combat missions at any time of the day or night. On the wings of the aircraft were fitted beamed holders of weapons. Each wing has been established for four of the types of CDD-60, each could carry up to 500 kilos of ammunition. The total weight of armament attack aircraft Yak-38 was one thousand kilograms.

Total full-scale production engineers made improvements and modernization, which led to the set of the most different modifications of this machine. Modernization mainly concerned avionics and engines of vertical take-off, which was not quite perfect. There have also been developed and training aids. Total use of attack aircraft Yak-38 lost a lot of machines, namely 48 devices, and it is only as a result of disasters that have been associated with a malfunctioning machine.

Yak-38M

 

The Yak-38 is a modification of the deck attack aircraft Yak-38 and its further development. This machine is able to produce a vertical take-off. It was developed by Yakovlev Design Bureau in 1982 year. Attack aircraft Yak-38M was in service in the Air Force of Ukraine and Russia to 2000 years.

History of the Yak-38M

The impetus for the creation of this unit was the appearance of the British aircraft with vertical take-off, which had a great time on the flight characteristics. In turn, the Soviet leadership has set a target to establish a similar device effective on the basis of already existing attack aircraft Yak-38. All these events were accompanied by the modernization of the old system and the creation of a qualitatively new unit.

Yak-38

The main task of the designers was to create a more powerful engine that would provide an effective vertical takeoff and greater traction in horizontal flight. To do this under the guidance of the designer O. Tabor was created an improved version of the main engine, which is designated as P-28-300. He gave the car traction in 6700 kg for vertical flight and 7100 kg when flying in a horizontal plane. They were modernized and lifting equipment that got traction in 3250 kgs and designated RD-38.

Production of the Yak-38M began in 82 year at the Saratov factory, which has produced Yak-38. And the first separation from the runway the aircraft produced in the late autumn of the same year, when this test machine took off vertically to a height of 7 meters. Complete horizontal flight was carried out in late winter 83 years. Factory tests and flights took place from December to June 82 83 years. After that, the unit was transferred to the State Commission for further tests. All state tests for attack aircraft Yak-38M were completed in 85 year and failed.

The serial production of the attack hit the 1984 year. He produced in the same factory as its predecessor, in the city of Saratov, for four years. During this time it was created 50 aircraft.

Design features of attack aircraft Yak-38M

When upgrading the device main changes were the engines, as have been involved all the forces of designers in the industry. It has been modified and the engine nozzle arrangement of the air intakes. These innovations helped to increase lift unit to 500 kilos. The fuselage has remained virtually the same, but was changed to place air intakes. This unit has a new nose landing gear, which had been controlled. Aircraft Armament also updated. Due to the on-board equipment machine could perform daily combat missions in all weather conditions.

Yak-38 cabin

Avionics has been added to the registration system and records all flight parameters, it was designated as a "tester UZL." To it was added to a funded system, "Edge-VM". It allows monitoring of all systems during flight. This has allowed designers to analyze what had to be finalized.

The fuselage of the machine is a semi-monocoque stringer with variable section. A feature of the car was that the front and tail parts are detachable, which has greatly simplified the installation or repair of the main engine. The cockpit has been made in the ventilation variant and can maintain normal climatic conditions for the pilot when flying at high altitudes. To reduce the distance of passing cars when landing on the Yak-38M installed brake parachute-type PTC 36M.

Wings consisted of two side members which are secured braced girder. On the wings were installed ailerons and flaps movable type. Wings have arrow-shaped, and the sweep angle was 45 ° on the front of the wing. The ailerons can deviate by an angle in 24 °, trimmers and provide turn in 17 °. The wing flaps are provided in the deflection angle 35 °. With respect empennage apparatus, it has been shown fixed stabilizer. In addition, there have been set handlebars that changes the height and direction of flight. The rudder can deflect a maximum at an angle of 30 ° in each direction, and the height of the trim tabs may vary at 17,5 °, too, in the two sides.

Yak-38m

All control rudders made bezbusterny system. An important role played by additional controls that provide excellent aerodynamics. Additional control systems are jet rudders, which are placed on the nose and tail of the machine body.

Chassis Yak-38M was represented by three pillars, which were installed pneumatic type wheels with low pressure. For a soft landing on the desks were provided oil-air shock absorbers. Front desk was manageable and allows control of the car on the runway. All-wheel drive system chassis equipped with braking systems.

Powerplant Yak-38M was presented PMD engine type P-28-300 and two lift units RD-38. The main engine was located in the middle section housing, on either side of him were air intakes. The engine was installed jet nozzle unregulated type, equipped with rotary nozzles. They were synchronized with each other and turned by a hydraulic system. Start power plant produces electric drive.

In the front section of the aircraft was equipped with two engines that produce vertical lift aircraft. They were directly behind the cockpit, equipped with an air intake. The nozzles of these engines were controlled with two valves. All engines apparatus worked on aviation fuel, which was taken in two tanks with a total capacity in 2750 kilos. One fuel tank was installed in the nose section between the engine unit and the second held the tail of the car.

Yak-38

For long-distance flights on the Yak-38M could install additional tanks, into which you can pour 400 kilos of fuel. The pilot was able to make his own adjustments in fuel consumption during the flight. To start the engines of the aircraft was equipped with a battery, which is placed directly at the engine.

Yak-38U

Yak-38 - deck training aircraft Yakovlev, vertical takeoff and landing. Designed for training pilots of carrier-based aircraft. Yak-38U based on the board following the heavy aircraft carrier "Minsk", "Kiev", "Admiral Gorshkov" and "Novorossiysk".

History of the YAK-38U

Double training modification of the Yak-36M intended for pilot training, namely for the development of vertical take-off and landing. The development of such a machine supposed directive of the CPSU and the USSR Council of Ministers in December 27 1967 years. 4 March 1971 city Air Force set their requirements (which were agreed with the management of aviation of the Navy). Already a testing Yak-36M served as an additional incentive. The plane was designated Yak-36MU and internal designation "MAS product." To stage "A" of its test has been designed layout (full-size) of the front part of the fuselage, showing the equipment cabin. In February, the 1972 A joint commission of its Navy and Air Force approved.

Yak-38U

Yak-36M characterized by compact dimensions and all its systems are the most dense in the space. That is why the cab add an instructor, allowing a normal review, the result was not easy. Engineers decided to increase the front part of the fuselage by placing the student in front of an instructor. In order to provide a good overview of the instructor, the nose of the aircraft was slightly tilted forward. Two separate cabins located tendemom had a flashlight. Also, to save the center of gravity had to be increased and the tail section. As a result, the car has received disproportionately long, surprisingly reminiscent of a banana.

In addition, we had to solve the problem of emergency rescue pilots. Designers managed to realize (the first time in world practice) bailout forced synchronous instructor and student during a flight in a vertical position, if the situation becomes unsafe. Hand bailout were synchronized with a slight delay, only 0,6 sec., And allowed themselves chairs breeding trajectories bailout, which excluded the clash pilots.

Home Test

The first aircraft assembly was completed in March 23 1973 years. On the same day he entered a phase of "A" state trials held in Zhukovsky. Michael Deksbah 17 August first flew Yak-36MU (he was accompanied by Yak-28, he ruled that Yuri Michiko). Then he was made a series of flights, the main purpose of which - the calibration of the receiver air pressure and determination of the safe conditions of use of air machine.

Yak-38U

Then the product VMC-1 taken to Ahtubinsk, on a test basis 8 State Research Institute of the Air Force to them. Chkalov. Since the end of September 1973 on July 31 1974 city were tested. 25 1973 October, the (via 1 month after the arrival) Michael Deksbah performed on the machine the first two hovering. A little later, in November-December of the same year, he performed a few hovering while on-site instructor. In 1974 year was made several flights that included reducing the rate to hover, start lifting engines in flight. At the height of 5 thousand. March 22 meters was reached maximum speed - 900 km per hour. Deksbah 4 days after the flight made by semi-profile. And it took off vertically and could develop a speed of up to 900 mph before landing on an aircraft. At full profile it made its first flight in March 30 1974 years.

During the stage of "A" was performed ninety-flight, which included both training and test flights. The results of this phase of the aircraft received positive reviews, although the state commission still advised to replace some of the equipment and avionics before the start of series production, and decided to continue the test sample.

Yak-38U

From April to September 1977 years on aircraft carrier "Kiev" passing phase "B" ship of state tests. According to its results we decided to take the aircraft into service. Then VMU-1 used to train pilots initially drill This user, and then in Saki (Crimea) at the airbase Novofedorivka. The car after the expiry of operation has been established as a monument.

Mass production

Documents for the start of series production were transferred to 1974 year Saratov Aviation Plant, as planned. In 1975 I was ready the first production aircraft. Serial numbers are assigned to individual aircraft, sometimes added to them "Y".

The State Research Institute of the Air Force tested the serial, in order to verify its controllability and stability after making changes on the results of the last stage of the "A". Vladilen Khomyakov was a test pilot, and replaced him with Viktor Vasenkov.

Yak-36 MU had such different from the test sample:

  • · Chassis with wide track;

  • · Modified air intakes;

  • · Ejection seats in the rescue of the crew;

  • · On the semiconductor electronic elements installed automatic control system;

  • · Dashboards cabins were slightly modified;

  • · Improved form of the keel;

  • · Change the position of the center of mass.

Since serial aircraft has no Recorder and test equipment, the assessment of its handling, features and operation of all systems was based on the experience of test pilots. Moreover, for the study of flight regimes applied testimony flight recorder.

20 April 1976 year on the results of these tests, the head of the State Research Institute of the Air Force developed the report. It dealt with the characteristics of the aircraft as a result of changes in its structure. Unfortunately, some of these improvements are insufficient and needed to take on these issues further measures.

Yak-38U

6 1976 October, the plane has a new index - the Yak-38U. 27 December this year, the third serial Yak was sent to the State Research Institute of the Air Force to take part in the next stage ("B") state tests. From April to 8 September 12 aircraft tested. Flights conducted test pilots V. Vasenkov, V. Hamsters and B. Golub. On the two machines during this time it was fulfilled forty operations, virtually all of them test. During state testing aircraft made 130 flights. November 15 1978, the order of the Minister of Defence of the Yak-38U have adopted. With regard to series production, it went along with the Yak-38 (four or five cars a year). Until Mr. 1985 at the Saratov aircraft plant was released 33 production aircraft, the last car had a number 0308.

UC 38 - the first Soviet production aircraft vertical takeoff and landing. With its creation, we use the data obtained in the development and testing of experimental models Yak 36. The aircraft was equipped with an elevator - sustainer engine and two lift R28 RD 38. As it was installed automatic pilot bailout in emergency situations.
Total built Yak 231 38 different modifications. Its production was carried out at the Saratov aircraft factory with 1974 1989 of the year.

About this machine can only say that he had read in a variety of sources. The most important feature of the Yak-38 / M / Y can be called Excessive engorgement. Only on takeoff and landing it took almost half of the fuel that was on board. In this way, you can not talk about a very small radius of action of the ego. Just Funny remains combat load the aircraft. And he was in the management of very complex and not every pilot could cope with this unit. It is very interesting and can be called a kind of bailout system, which is triggered automatically when the time hovering roll machines exceeded the critical level. In addition the first car of this class could not fly at all during their operation at low latitudes. Yet upgraded models were able at least for something.
