FIELD: aircraft construction, particularly liquid storage and transportation devices, which may create modular system to locate water tanks of different sizes and adapted to be used in aircrafts of various types for fresh water supply and sewage water removal.
SUBSTANCE: device comprises liquid reservoir 1 made as tank half 11 or tank one-third 12 or tank one-quarter 13 or as cylindrical tank 19. Pouring orifice 14 is created in reservoir bottom 6 and is shifted from bottom center. The pouring orifice is made in bottom 6 part located near bottom edge from vertical axis 14 side. Partial flange 7 is connected to pouring pipe 2 from outlet side. The partial flange 7 is supplemented with solid flange 8. Both flanges form the first round flange 9 secured to the second round flange 10 so that end surface of the first round flange adjoins the second round flange 10. Pouring line 4 is linked to the second round flange 10. Pouring line 4 has outer diameter d equal to that of the first and the second round flanges. Center of circle defined by end surface of each flange 9, 10 is in register with center of circle bounding cross-section of pouring line 4. Partial flange 7 is made as half-flange 71 or flange one-third 72 or flange one-quarter 73. Additional solid flange 8 includes solid half-flange 81 or solid flange one-third 82 or flange solid two-third 83 or solid flange one-quarter 84 or solid flange three-quarters 85. Jointing sides of partial flanges provide close flange fit with each other. In the second variants device comprises several liquid reservoirs 1 arranged about imaginary vertical axis 14 passing through center of circuit. Reservoirs of the same size are distributed along the circle around vertical axis 14.
EFFECT: simplified device assemblage and supply line connection, decreased variety of necessary connection members and pipelines, elimination of difficulties associated with said connection members and fasteners usage.
