Kazakhstan Wants to Buy Yak-152 Airplanes, Not Contribute to Designing: Here
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.

СКС-94 emergency escape system for acrobatic and light airplanes
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.
Yak-152 propulsion and performance
The Yak-152 is powered by a single M-14X turboprop engine with a generating capacity of 360hp.
New Yak-152 Trainer Will Come With Alternate Powerplants
The Irkutsk Aviation plant (IAZ) of Irkut Corporation has mated the fuselage with the wing of a prototype Yakovlev Yak-152 twin-seat weaponized piston trainer. The project was revealed at the Singapore Airshow and is said to be on track for first flight by year-end. Both piston and diesel-powered versions are planned.
The fuselage is a semi-monocoque all-metal construction except for the engine cowling, which is made of carbon-plastic. Wings are made of aluminum alloys. Yakovlev says the extensive use of metal is for simplicity of manufacturing, ensuring low costs, as well as for ruggedness and ease of repair.
“The prototype is powered by a diesel from Raikhlin Aircraft Engine Developments (RED) of Germany. It is available in two versions, 300 (A05/V12) or 500 hp (A03/V6). The latter provides sufficient power for the Yak-152 to fly with four underwing weapons pylons and up to 550 kg [1,100 pounds] of munitions on them.”
“But the requirement from Russia’s Air and Space Force (VKS) is for 150 aircraft in the roles of screener and basic trainer. For this and other domestic customers, the Yak-152 will be powered by the M-14X radial nine-cylinder piston engine from the Experimental Design Bureau of Engine Building (OKBM) based in Voronezh. The M-14X is a recent, more powerful version of the popular Vedeneyev M-14P that develops 360 hp at “maximum” mode and 400 hp at “emergency.”

“We were told to do everything to reduce dependence on import,” an authoritative sourсe at Irkut told AIN. He added that the diesel version will be largely offered for export, whereas local customers insist on “a completely Russian solution.”
M-14P – Image: 3dcadbrowser.comM-14P – Image: 3dcadbrowser.com
The M-14X-powered version is lighter, with gross weight (with the RED A03/V12 engine) reduced from 2,125 kg (4,685 pounds) to 1,400 kg (3,086 pounds). It has g limits of +9/-7; the g limits of the diesel version are+5/-3. While the maximum diving speed remains at 500 km/h (270 knots), the maximum level speed drops from 380 km/h (205 knots) to 335 km/h (181 knots). The maximum climb rate rises from 8 to 11 meters per second (1,575 to 2,165 ft/min). Takeoff run decreases from 300 (990 feet) to 200 meters (660 feet). The landing run is reduced from 450 meters (1,485 feet) to 250 meters (825 feet), as a result of the landing speed going down from 145 km/h (78 knots) to 115 km/h (62 nots).”
Yakovlev claims that the M-14X-powered Yak-152 has a 7 percent advantage over the closest competitor in maximum range (on inner fuel it can cover 1,500 km or 810 nm) and a 15 percent advantage in the rate of climb.
The design bureau suggests that the Yak-152 will appeal to sport fliers and for export.
For IAZ, the Yak-152 represents a second completely digital aircraft design. The first was the Yak-130 advanced jet trainer, which is being produced at a rate of 30 units annually. Source ainonline.com
