In the article D. Vereshikov, S. Saltikov, I. Makarov «The interference influence between airplane wing and aviation defeat means on the characteristics of lateral balancing of the airplane at supersonic speeds» presents the results of research in the direction of the authors study the effect of the interference interaction of wing and suspension cargo to a need for balance the lateral deviation of the aircraft controls the formation of an asymmetric configuration, location the load. The authors single out a special way the interference forces acting on the suspended load as a result of its interaction with the downwash in the vicinity of the aircraft wing. Numerical research and analysis of domestic and foreign literature the authors give a reason to assert that the interference forces due to under-wing cargo, can be substantial and comparable with the weight of the cargo themselves. The direction and magnitude of additional interference forces is determined by the flight Mach number and position of the load along the chord and wing span. The availability of strong interference aerodynamic loads leads to that the need for balance the lateral deviation of aircraft control are significantly different from those that may be predicted as a result of calculations without interference interaction of the aircraft and the suspended load. The article presents the results of calculations of balancing characteristics of the aircraft at different flight Mach numbers and positions of the suspended load and explains the physical nature of the formation of interference forces and moments, and as a result, changes in the balancing of deviations of lateral control of aircraft.
