Manufacturer Irkut has revealed that the Russian Ministry of Defense has ordered 150 Yak-152 basic trainers. The announcement was made by plant director Sergey Yamani as the company unveiled the three aircraft under various stages of assembly at their plant in Irkutsk. Operated by a single pilot, the cockpit can accommodate two crew members in tandem configuration. The aircraft is intended to provide primary pilot training, professional selection, and occupational guidance for future pilots of military fighter aircraft.

Defense Ministry ordered 150 light trainer aircraft Yak-152
Currently at the plant in various stages of assembly are three Yak-152.
“At present the Irkutsk aircraft factory proceeds to the order of the Ministry of Defense, which has ordered 150 of these vehicles,” – he said.
He recalled that the two-seater plane has a speed of up to 350 kilometers per hour, and has a catapult.

The primary trainer Yak-152 included into the UTK-Yak training system and is intended for pupil- pilots primary teaching and professional selection at early stages of training process.
The Yak-152 is a single-engine, two-seater, low-wing monoplane of a classical configuration with a retractable tricycle landing gear with nose wheel and the M-14X engine. Shock-absorbing properties of the landing gear with low pressure tires, short takeoff and landing run make it possible to operate the aircraft on small unprepared airfields.
New Yak-152 Trainer Will Come With Alternate Powerplants
“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.”

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).” Source ainonline.com
Introducing the Raikhlin RED A03 500HP aero diesel

Press Release: Raikhlin Aircraft Engine Developments GmbH, a new venture founded by Wladimir Railkhlin and his associates, successfully completed a full-scale flight test of the most powerful modern diesel piston engine designed for General Aviation. Initial flight test on a modified Yak 52 is the beginning of the exploration of defined parameters for RED A03 engine installation within which the engine may operate – from normal to extreme conditions. It is a water & oil-cooled double OHC, V12, common-rail direct injection engine. The propeller is gear-driven (single-stage, 1/1.67 ratio). Compression is 16.5. It is the product of RED Aircraft GmbH in Adenau, Germany. Testing location was limited by the range of the telemetry equipment on the ground. The engine generates 370 kW (500HP) take off power in basic specification, at around 3,900 rpm, showing a specific (JETA/diesel) fuel consumption of 210-220 gr/kWh. Full spec. engine weight at the moment is 320 kg (705 Lbs.),- two alternators, starter, engine/gearbox oil heat exchanger, prop governor. Initial test data showed the engine performance met all expectations, says RED’s management. Information collected from this test, together with data from former development tests, will be evaluated to better understand the performance and reliability of the design. Indeed, the RED A03 bridges the traditional gap between piston engines and substantially more expensive turboprops. RED Aircraft GmbH is in DOA and TC certification process with EASA.

The aircraft-mounted equipment enables the pupil-pilot to acquire the skill of using the up-to-date flight-navigation, radio communication and aiming equipment.The Yak-152 has a tandem cockpit configuration for two pilots. The front seat is intended for the pupil-pilot, the rear one is for the instructor. One crew member may fly the aircraft from either seat. The aircraft is equipped with the SKS-94M ejection system to provide safe escape for crew members.
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.

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.
