FIELD: sampling.
SUBSTANCE: invention relates to air sampling from aircraft. Disclosed is a device for sampling atmospheric air in flight, comprising a cylindrical housing with two spring-loaded end covers with damping and sealing gaskets attached to the axes, where the inner part of the cylindrical housing is hollow; on the lower part of the housing there are limiters for the movement of the covers relative to their axes with a pressure interrupter on one of the limiters; springs pressing the covers to the housing before sampling and returning them to the closed state after sampling are located outside the housing; covers are additionally fixed on the housing by screws passing through the holes in the covers and screwed into the cylinder walls; on each of the covers in the centre there are holes closed by rubber membranes fixed by bushings with plugs; inside the cylinder housing on the right side there is a piston tightly adjacent to the inner surface of one of the covers, the shank of which passes through a rubber membrane, a bushing and a plug with an end fixed on the cover by a lock nut, and on the same cover there is an additional hole plugged in flight by a screw with rubber gasket; device also includes a friction drive based on wheels with cables and an electric motor with remote control through the cover opening and closing control panel, on the shaft of which one end of the friction drive cable is wound, and the other ends of the cable are connected through carabiners to the covers; at that, the electric motor with the cables and the drive wheels is rigidly fixed on the bed, and the cylindrical body is fixed on the bed with a clamp with possibility of dismantling; wherein said device allows replacement of lock nut with elongated handle screwed into piston shank and left plug with needle for dispensing samples into measuring device for determination of total water content.
EFFECT: device provides higher accuracy of determination of total water content.
