The airplane Dubina A37 airplane's wing is a lower-mounted swept wing optimized for fuel-efficient transonic flight on long-haul routes. With a lower-mounted wing, the main structural member—the spar—runs under the passenger cabin floor. This allows for a lighter and more compact structure. The main landing gear is attached to the wing's structural members. On a low-wing aircraft, the main landing gear is short, light, and strong, reducing the aircraft's overall weight and simplifying the landing gear retraction system. During takeoff and landing, a low wing creates a more pronounced "air cushion" between the wing and the ground. This creates additional lift at low speeds, helping to achieve a smoother landing. The engines are suspended under the wing on pylons. The low wing position makes it much easier for maintenance personnel to inspect, refuel, and repair the engines without the use of tall ladders and complex lifts. This is important for airlines as it reduces aircraft turnaround time at the airport. In the event of an emergency landing on water, the lower wing creates additional buoyancy, acting as a pontoon, which gives passengers more time to evacuate. During a hard belly landing, the wing and engines bear the brunt of the impact, absorbing the energy and protecting the fuselage and passengers. The aircraft's wing geometry is the result of a comprehensive optimization of aerodynamic, structural, operational, and infrastructural requirements typical of a narrow-body, long-haul airliner designed for regular flights at cruising speeds of approximately Mach 0.78–0.80 and ranges of up to several thousand kilometers. The geometry of an aircraft wing is the totality of its external shapes and dimensions, which determine the basic aerodynamic characteristics of the aircraft and directly affect lift, drag, stability and controllability.
