The purpose of creating of the Mi-2MSB helicopter is need to improve the flight performance of Mi-2 helicopters during operating in hot climate, highaltitude take-off areas and high flight altitudes. The main advantage of Mi-2MSB helicopter lies in installation of new generation engines AI-450M-B characterized by significantly improved performance characteristics and service life due to the use of new materials and design solutions and having the following advantages:

The above engine incarnates the best design solutions and provides the helicopter with the following advantages (in comparison with Mi-2
helicopter):

• reduction of fuel consumption per hour by up to 30%;
• increase of load-carrying capacity by 25%;
• increase of flight range by 30%;
• increase of the hover and service ceiling by 20%;
• substantial improvement of helicopter performance in hot climate and high-mountainous conditions;
• stable operation in dust- and smoke-laden conditions;
• easiness of field maintenance, high maintainability and reliability;
• low cost of life cycle;
• twofold increase of engine TBO
