Abstract: A wing drop fuel tank it is provided comprising a rigid external casing 1 and a second tank 2 arranged inside said rigid casing 1, said second tank 2 being made of flexible material. A production process of said wing drop tank it is also provided which comprises the following steps: construction of two rigid half-shells 10 and 11, and the subsequent mutual coupling of the former creates a single rigid structure 1; making of a first port and a second port at the upper part of the half-shell 10, said second port having same size of a fuel filling flange 23 on said tank 1; inserting of a second tank 2 made of a flexible material through said first port in said first tank 1; and applying a closing plate 12 at said upper port, said closing plate 12 being removably locked on said tank 1 by means of clamping screws 13 which engage with threaded holes 22 made on a flange 21 integral with said second tank 2.

Abstract: A suction system for a liquid reservoir, the reservoir being defined by top wall, side walls, and bottom wall. The system includes one layer of a permeable material arranged inside said liquid reservoir and fixedly connected to said bottom wall of said liquid reservoir; fixing means for fixing said permeable layer on said bottom wall of said liquid reservoir; suction means of said liquid arranged within said permeable layer; and connecting means of said suction means to a suction duct for said liquid. The arrangement being such that an internal volume for the containing of liquid is defined between said one layer of permeable material, said fixing means, and said bottom wall of said reservoir, wherein the liquid is sucked into said internal volume and through said layer of permeable material and through the suction means.
