Реферат: 843,512. Jettisonable tanks for aircraft. SOC. D'ETUDES ET DE CONSTRUCTIONS AERO-NAVALES. Oct. 14, 1957 [Nov. 16, 1956], No. 32085/57. Class 4. [Also in Group XXIX] A jettisonable tank for an aeroplane consists of two half-sections 1, 2 which are made by assembling in a mould fibrous sheets of glass cloth impregnated with resin. The half sections 1, 2 respectively are formed with flanges 3, 4 which are glued together and the joint covered with strips 5, 5a, 5b of glass cloth impregnated with resin. Reinforcing portions 6 of crescent shape are placed across each of the half-sections 1, 2. The lower half-section 1 has a half-moon shaped partition 7 in which holes 7a are drilled. This partition prevents the liquid rolling in the tank. The various accessories such as clips 9, centring plugs 10 and tubular shoulders 11, or other accessories 12 with which the tank is provided are grouped and secured in a part 8. This part 8 is made in a mould in which accessories 9 to 12 are previously arranged. Certain accessories may be placed at other points in the half section 2. These accessories are embedded in reinforcing and supporting parts 8a of similar design to the part 8. Filler plugs 13 and other accessories to which no particular stress is normally applied can be mounted in a slightly different manner. As shown in Fig. 3, the plug 13 is screwed into a shoulder-part 14 which is secured to the half-section 2 by nuts 20 and screws 19 which are soldered to a collar 18. An annular reinforcement 21, made of glass cloth impregnated with resin, covers the collar 18. A fin 22 is connected to the half sections 1, 2 by means of lugs 23 comprising curved parts 24 of reinforced synthetic resin which are glued to the bottom part of the tank after the two half sections are joined together.
