The study considers a maneuvering load reduction system as applied to the prototype of
a modern short-haul passenger aircraft equipped with a digital flight control system. The
paper describes the system configuration and introduces the optimal structure based on
the characteristic features of the flight control cueing, the power unit architecture and its
component reliability. When calculating the parameters of this system, the mathematical
model of the aircraft was used, this allows considering the element elasticity of its design.
To evaluate the efficiency of the system for reducing the wing bending moments during
maneuvering, we carried out the calculations, taking into account the flight control sys-
tem features of the controlled element under consideration.
Keywords: maneuvering load reduction system, wing bending moment, normal accelera-
tion, spoilers, ailerons, digital flight control system
