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.

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.

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.

Primary Trainer

Yak-152 primary training aircraft constitutes a new trend of Irkut Corporation activity in the sphere of flight trainer development.

Yak-152 aircraft is a component of the integrated training system designated for training pilots of contemporary and prospective aircraft. This system also includes flight simulators, computerized classrooms, as well as monitoring and control means.

Yak-152 provides implementation of key tasks of primary flight training by day and night.

Yak-152 is designated for training in:

  • piloting technique, including basic, advanced, and aerobatic pilotage;
  • navigation basics;
  • spin in and spin off techniques;
  • instrumental en-route flight and landing approach using the airfield ILS;
  • group piloting at daytime, in VFR and over clouds;
  • acting in emergencies.

Aerodynamic configuration of the aircraft ensures flight safety during improper piloting.

Yak-152 is equipped with the innovative RED A03T piston diesel engine fueled with aviation kerosene.

Inside the unpressurized two-seat  cockpit pilots  are ‘tandem’ positioned. The forward crew station is designated for trainee, the aft one accommodates instructor.

The Yak-152 avionics suite provides:

  • indication of data on multi-function LCDs;
  • triple redundancy of flight-and-navigation equipment;
  • registration of flight information and aircraft systems’ performance data, as well as recording of crew’s voice conversations to a hardened on-board recorder;
  • automatic response to requests of IFF radar systems and secondary radars of traffic control systems.

The distinctive feature of Yak-152 aircraft is the unique SKS-94M ejection system providing emergency escape of both crew members.

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.

The aircraft is capable of operating from small airfields with ground strength of 5 kg/сm2 .

The possibility of outdoor storage is envisioned.

Service life is not less than 10,000 hours, 30 years, and 30,000 landings.

Aggregates, systems, and equipment of the aircraft may be operated on condition.

Simplicity of design, convenient access to aggregates and wirings facilitate aircraft maintenance.

Designers of Yak-152 leaned on a wealth of experience amassed by Yakovlev Design Bureau in development of training aircraft. Since 1935, more than 22,000 UT-2, Yak-11, Yak-18, Yak-52 piston-engine trainers have been manufactured in Russia and abroad. Source irkut.com

Yak-152 propulsion and performance

The Yak-152 is powered by a single M-14X turboprop engine with a generating capacity of 360hp.
