MAI has developed a mechanism that closes the gap between an aircraft's wing and aileron. According to the developers' calculations, the solution can increase wing lift by 5–6% and reduce aerodynamic drag by approximately 10%. The effect may be particularly noticeable during takeoff and landing.

The mechanism was created by Mikhail Gorkin, a design engineer at MAI's Institute No. 1 "Aircraft Engineering". The design is based on a flexible plate made of a hybrid polymer composite material, combining carbon fiber and organoplastic.

The gap between the wing and the aileron is necessary for its deflection, but during flight, airflow passes through it. This increases drag and reduces wing efficiency. The new design is intended to block this channel while simultaneously bending with the movement of the aileron.

A separate drive for the plate is not needed. It is installed near the aileron's attachment point on the wing's trailing edge. When the control surface deflects, the material deforms with it, maintaining a continuous aerodynamic contour.

For the design, VKU-45 carbon fiber and VKO-25 organoplastic based on VSE-34 polymer binder are proposed. This combination should provide both high strength and the ability to withstand significant deformations without failure.

Currently, the stated characteristics have been obtained on two-dimensional models. Preliminary estimates show that drag reduction can be about 10%, and lift can increase by 5–6%. The most pronounced effect is expected at low speeds, particularly during takeoff and landing.

Developers estimate potential fuel savings of 0.5–0.7% of its mass in the tank. For a long-haul flight from Moscow to Vladivostok, this could correspond to approximately 100–200 kg of fuel per flight.
