The invention belongs to the technical field of aerodynamic wind tunnel tests, and discloses an aircraft ventilation force measurement wind tunnel test device and an installation method and a test method thereof. According to the aircraft ventilation force measurement wind tunnel test device and the installation method and the test method thereof, two devices and methods of a force measurement wind tunnel test and an air inlet channel test are comprehensively utilized, and the flow of the air inlet channel is accurately adjusted and measured through the flow meter; the method comprises the following steps: acquiring the comprehensive load of an aircraft model under a wind tunnel test condition and under different air inlet flow through a balance, and deducting the bottom resistance of the aircraft model measured by a bottom resistance measuring device and the internal resistance of the aircraft model measured by an internal resistance measuring device; the aerodynamic characteristics of the aircraft model und
