The paper proposes an approach to solving the problems of stability and controllability of aircraft of the aerodynamic «flying wing» scheme from the point of view of movement on the ground, which consists in combining landing gear systems into an automated integrated control loop. The analysis of the features of movement on the ground is carried out, the disadvantages and boundaries of the application of the existing control methods are indicated. The construction of a dynamic aircraft model for virtual testing of control algorithms is described. The conclusion is made about the practical advantages that are expected as a result of the introduction of an integral control loop for chassis systems.
Keywords: landing gear, stability and controllability, flying wing, automation, integral control loop.
