The Yak-152 is being developed and promoted as the next generation basic trainer for military and aerobatic trainees. Designed by the Yakovlev Design Bureau, it is the long anticipated successor to the Yak 52, which has been in operation in a similar role since 1976. The Yak-152 shares some common features of it’s predecessor. It is a dual seat, single engine, monoplane aircraft.
The inaugural flight of the Yak-152 took place in September 2016 at the Irkutsk aircraft building plant, and due to its initial success, has been subject to an order placed for 150 aircraft to be delivered to the Russian Ministry of Defence. The aircraft will be manufactured by the Irkut Corporation in Eastern Siberia. The first delivery of the Yak-152 airframe in fulfillment of that order took place in 2017.
The aircraft seating is configured in the ‘tandem style’ in an unpressurised cockpit. With the primary pilot sitting in the front seat with an instructor in the rear, regardless of seating position the aircraft has dual controls and instrumentation and can be completely controlled from either station. The high visibility bubble canopy affords excellent views making it ideal for training when operating under visual flight rules.
The avionics system on the Yak-152 is computerised and displayed in the ‘glass cockpit’ concept. This is beneficial for several reasons including; multi functionality of displays, increased redundancy protection, and efficiency in flight data recording. The onboard glass cockpit has several useful benefits in the training environment. With the optional installation of hard points when used a military trainer, the avionics suite also forms an interface to allow training in the control of mounted systems. Furthermore certain failures can be synthetically replicated by using a control panel located in the rear instructor seating position. Overall the glass cockpit concept gives better situational awareness leading to an increase in flight safety.
Like the Yak-52M the aircraft comes fitted with an emergency ejection system designed to allow flight crew to quickly and safely egress from the aircraft in the event of unrecoverable emergencies.

Key Features of the Yak-152
A key feature of the new Yak-152 is its simple structure, allowing easy access to systems and pipelines meaning that maintenance is possible with minimal ground servicing equipment. With regards to reducing maintenance costs, storage issues have also been addressed in the Yak-152’s appeal. It is manufactured using materials that allow it to be stored outside of a hangar with minimal degradation to reliability.
As a military and aerobatic trainer the aircraft excels, as it is purpose built for such a role. The ability to perform high energy and dynamic manoeuvrers is demonstrated by it’s handling characteristics. With two pilots onboard the airframe is capable of withstanding G-Loads ranging from +8G to -6G, with one pilot onboard it’s envelope is rated to fly from +9G to -7G. Further to this the aircraft has been designed to give high aerodynamic and low drag efficiency. It’s power is only further enhanced by a high thrust to weight ratio, which exceeds that of it’s predecessor. At full power in ISA conditions the aircraft offers and impressive rate of climb of around 2000 feet per minute.
Just like it predecessor the Yak-152 is designed to operate into short airfields. It is rated for landing on both paved and unpaved surfaces. The landing gear is fully retractable and is configured in the tricycle style, making for an easy and consistent landing technique, which is necessary when an aircraft is utilised as a trainer.
Unlike older generations of aeroplanes thrust control and propeller pitch is controlled simultaneously by a single lever. As this aircraft has been developed as a military trainer this is designed to replicate a similar control style as is found in modern jet fighters.
