The paper describes the phenomenon of the occurrence of aerodynamic interference between a helicopter and an object in its near vicinity. Such situations occur during rescue missions as well as during police and military operations when the helicopter flies near such objects as buildings and ships. The specific shape of the example object, a typical town courtyard, is discussed below. The influence of the interference on the rotor and fuselage loading, air flow and flying qualities was analyzed for these special cases of helicopter operations. The results of the computations performed using the FLUENT software in terms of the dynamic response to disturbances on the simulation model of a helicopter rotor have been presented. The model used in these calculations made it possible to analyze flexible rotor blades. The results of the experimental tests of interference between the helicopter model and different shapes have been attached, as well.
