Antonov An-158

An-158 is a continuation of the An-148 lineup. Due to the increased number of seats per passenger kilometer, aircraft performance improved by 15-18%. At the same time, in terms of fuel efficiency, the new An slightly surpasses the Sukhoi Superjet 100 (SSJ100), which is close in dimension due to the better wing and D-436-148 engines, which are more economical than SaM.146. According to preliminary estimates, in the cruise flight mode with a Mach number of 0.7-0.75, the An-158 has an aerodynamic quality 0.5-1 unit higher than the SSJ100, and its power plant consumes 3-5% less fuel. This is because the An-158 has a larger wingspan and elongation with a slightly smaller fuselage diameter (which makes its glider more “volatile”). At the same time, the progressive three-shaft D-436 scheme has several advantages over the simpler two-shaft SaM in design. 146.

 An-158 complements the base aircraft of the An-148-100 family in production and operation. “Where passenger traffic is not very saturated,” Alexander Dmitrievich explained, “customers are happy to bet on the An-148-100 with a capacity of 68 to 80 seats. On routes with large passenger flows, it is more profitable to operate the An-158, designed for 99 seats Together with our Russian partners, we will be able to offer a full-fledged family of aircraft that will allow the customer to get the optimal combination of different models in his fleet, while the An-158 has a very high degree of unification with the An-148: single cabin, systems, units, glider elements, etc. Therefore, the cost of training crews and maintaining the fleet in good condition is low, which is beneficial to operate organizations. “
