The invention discloses a device for generation, storage and transportation of a helicopter rotor flow field display medium. The device comprises a display medium generator, a storage box, a controller and a conveying tube; both the display medium generator and the controller are connected with the storage box; part of the controller or the whole controller is positioned in the storage box; the conveying tube is connected with the outer side of the controller. The main components of a raw material used by the device for generation, storage and transportation of the helicopter rotor flow field display medium are ethylene glycol, glycerol and purified water, the generated smoke fog, namely the display medium, has little harm to a human body and equipment basically; compared with a conventional method, the concentration of the smoke fog can be more conveniently and exactly adjusted by replacing smoke oil, observing the concentration of smoke fog in the storage box, and adjusting the exhaust air rate of the controller; the influence of the generated smoke fog to a flow filed is reduced to the minimum, and the movement of the smoke fog in the flow field along with the flow field is more obvious.
