Yak-152 Primary Trainer Aircraft

The Yak-152 is a new-generation primary trainer aircraft developed by Yakovlev Design Bureau, a part of Irkut Corporation. The aircraft is intended for the Russian Ministry of Defence, paramilitary sport organisation DOSAAF (Volunteer Society for Cooperation with the Army, Aviation, and Fleet), and other organisations of the Russian Federation.

The aircraft is intended to provide primary pilot training, professional selection, and occupational guidance for future military fighter pilots. It will be included in the UTK-Yak training complex, which consists of the Yak-130 combat trainer, computer display classrooms, PC-based procedural simulators, and functional simulators.

Yakovlev Design Bureau is the potential prime contractor for the Yak-152 aeroplane. Federal arms supply agency Rosoboronpostavka began a tender in March 2014 to complete development of a Yak-152 piston training aircraft at an estimated cost of RUR300m ($8.32m). A mock-up of the Yakovlev-152 trainer was made by OSKBES MAI in September 2014.

The Yak-152 aircraft development programme includes production of four prototypes, with two are aimed for flight trials, one for static tests and the final for fatigue testing. . The first prototype achieved its maiden flight in September 2016. The first Yak-152 trainer aircraft is anticipated to be operational by 2017.

Irkut received a contract from the Russian Ministry of Defence (MoD) in June 2015 to supply approximately 150 Yak-152 aircraft by 2020.

Excerpt

Russia`s Ministry of Defence (MoD) is planning to sign a contract with the Irkutsk Aviation Plant (a subsidiary of the Irkut Corporation) for the first three Yakovlev Yak-152 basic trainers later in 2017, Deputy Defence Minister Yury Borisov said during a visit to the enterprise.

“I hope that after the completion of the preliminary trials this year we will sign the contract for the delivery of the first three Yak-152 trainers intended for the basic training of cadet pilots,” Borisov said while watching the demonstration flight of the prototype, adding, “The impression of the flight is very good.”

Excerpt

The flight prototype No. 2 built at the Irkutsk aircraft plant, the branch of the Irkut Corporation PJSC, will begin undergoing flight tests in the nearest future.

“We were licensed for two-pilot flights in the spring”, Vasily Sevastyanov, 1st Class research pilot told Mil.Today. So far, he has been flying on the new plane alone; however, the second pilot has already started training program.

Excerpt

Yak-152 airplanes will become the first phase in the new flight training system of Russian and Belarusian military pilots, preparing cadets for further changeover to Yak-130. The latter jet, in turn, will help to train Su-30SM pilots. 

Kazakhstan’s air force operates six Su-30SM fighters being imported since 2015. In total, by 2020 Russia may deliver up to 24 jets of this type to its southern partner. 

Alongside with that, Kazakhstan has procured Zlin-242L trainer airplanes from the Czech Republic. These planes are designed for training flights, aerobatics, and glider towing. Although Astana does not waive procurement of Yak-152, it waits for successful completion of trials, the Kazakh insider shared with Mil.Today

Yak-152 trainer aircraft design and features

The Yak-152 primary / basic trainer aircraft features all-metal airframe, low wing, aerofoil monoplane design. It is easy to maintain and requires low operating costs.

The wings are attached with trim rudders and ailerons to provide improved aerodynamic efficiency. The aircraft features a retractable tricycle landing gear consisting of a nose wheel and two main wheels, with low-pressure tyres and shock-absorbing properties, allowing the aircraft to take-off and land safely on small unprepared airfields.

The Yak-152 trainer aircraft has a length of 7.72m, wing span of 8.82m and a height of 2.47m. The maximum take-off weight is 1,320kg and it can carry a maximum fuel load of 200kg. It features a monocoque fuselage made up of four longerons.

Operated by a single pilot, the cockpit can accommodate two crew members in tandem configuration. The pupil-pilot seat is located in the front section, while the instructor is seated at the rear. The aircraft uses the SKS-94M ejection system to provide safe escape for pilots in case of an emergency. It is also installed with heating and ventilation systems.

Avionics of Yakovlev Design Bureau’s trainer aircraft

The Yak-152 primary trainer aircraft can be equipped with advanced flight navigation, radio communications, and targeting equipment to provide high-reliability and enhanced training capabilities for the pilots.

High reliability, simple structure, access to the system units and pipelines ensure easy maintenance with minimum costs for flight preparation with minimum available ground servicing equipment. The wing aerodynamic configuration, wing planform and airfoil have been selected to provide the aircraft functions of primary training and aerobatics.

The CKC-94 system is designed for pilots’ escape from acrobatic and light airplanes; the system is one of the CKC-94 system modifications operated in the Su-31M, Su-26M3 and Yak-52M airplanes.

All versions of the system have passed through the State Test Program.

The СКС-94М2 emergency escape system features:

  • СПС-99 parachute system having a minimum weight and minimum volume when packed;
  • restraint system providing reliable restraint of the pilot in the seat exposed to accelerations in any direction;
  • stepless height adjustment.

The СКС-94М2 system provides safe emergency escape from the single-seat and two-seat airplanes at the flight speeds from 70 to 400 km/h and altitudes from 10 to 4000 m (with trajectories diversion at the simultaneous ejection of two pilots from the wrecking aircraft).

The СКС-94М2 useful lifetime is 30 years.

The routine maintenance is performed every 5 years.
