A transmission system

A transmission system (1) comprising:

• an air vehicle (V);
• a body (2) separating the areas on the air vehicle (V) from each other;
• a plurality of pipes (3) located on both sides of the body (2) in connection with the body (2), which allow fluid to be transferred therethrough;
• an opening (4) located on the body (2) so as to provide fluid passage between the pipes (3);
• a plurality of fasteners (5) that enable the pipes (3) to be connected to each other and/or to the body (2);
• a flange (6) that extends outward from the pipe (3), allowing the fasteners (5) to be placed thereon;
• at least one sealing element (7) located between the flange (6) and the body (2), which provides sealing during the passage of the fluid between the pipes (3);
• a first pipe (301) and a second pipe (302) of the plurality of pipes (3), which are connected on the body (2) in an opposed manner such that the opening (4) is therebetween;
• a first environment (I) on one side of the body (2), into which the first pipe (301) extends and a pressure value of which is kept at a value predetermined by the user;
• a second environment (II) on the other side of the body, which has a pressure value lower than the first environment (I), and into which the second pipe (302) extends;
• a passage element (8) located between the first pipe (301) and the second pipe (302);
• wherein the second pipe (302) provides fluid transfer to the first pipe (301) through the opening (4);
• an inner sealing extension (9) extending over the second pipe (302) towards the passage element (8) so as to be in contact with the wall of the opening (4), thereby enabling the fluid in the second pipe (302) to be transferred substantially to the first pipe (301);
• a transmission line (10) that allows the fluid to be transmitted by being surrounded by the pipe (3) and/or the passage element (8);
• and
• a protrusion (11) with a narrower cross-section than the pipe (3), extending into the transmission line (10) over the passage element (8) so as to narrow the cross-section of the transmission line (10), and regulating the flow of the fluid hitting thereon.
