In the present study, a new experimental setup for the investigation of the aerodynamic in-teraction between a helicopter and ground obstacles is presented and assessed. The motorised helicopter model, which includes the fuselage, can be positioned in different positions relative to a model building in order to replicate different configurations. Moreover the current setup can also be used in a wind tunnel in order to replicate interference effects in windy conditions. The use of a helicopter model with a six-component balance and a building model with several pressure taps allows a database to be compiled for the loads on the helicopter and obstacle. A physical interpretation of the flow phenomena can be obtained through analysis of the obstacle pressure measurements and particle image velocimetry surveys of relevant configurations.
