Abstract
The utility model belongs to in aircraft seal structure field, specifically an aircraft activity hollow shaft watertight structure, this structure mainly comprises toper rain shield, annular rain shield, rudder pivot and fuselage covering etc. and each part adopts sealed riveting connection form. The utility model discloses can block the inside that the rainwater got into the aircraft from the rudder pivot, reduce aircraft structure and airborne equipment's corrosion, improve flight safety.
Description
Technical Field
The utility model belongs to aircraft seal structure field specifically is an aircraft rudder pivot watertight structure, can block that the rainwater gets into the inside structure of aircraft from the rudder pivot.
Background
The problem of water leakage of the rudder rotating shaft mainly has two ways, namely, a water receiving box is added at the bottom of the rotating shaft and then is led out of the machine body through a water pipe; and secondly, water leakage holes are additionally arranged at the bottom of the airplane for draining water. Neither of the above two solutions can solve the problem of passive drainage of rainwater into the interior of the aircraft. The utility model relates to a rudder pivot watertight structure can block that the rainwater gets into the inside structure of aircraft from the rudder pivot.
Disclosure of Invention
The utility model discloses the purpose is guaranteed the rudder pivot watertight, can block that the rainwater gets into the inside structure of aircraft from the rudder pivot.
Technical scheme
A watertight structure of an airplane movable pipe shaft comprises a conical rain shield and an annular rain shield, wherein the conical rain shield is arranged on a rudder rotating shaft at an opening of an airplane body, and the annular rain shield is arranged around an opening skin of the airplane body; the conical rain shield and the annular rain shield are in sealing riveting with the machine body and the rudder rotating shaft.
The conical rain shield and the annular rain shield are made of aluminum alloy.
The thickness of the conical rain shield and the annular rain shield is 2 mm.
The top end part of the conical rain shield is provided with a round hole, and the round hole is in gapless connection with the rudder rotating shaft.
And sealant is coated between the conical rain shield and the rudder.
The annular rain shield is cylindrical with a flange, and the flange is in sealing riveting with the machine body.
Technical effects
Compared with the prior art, the utility model has the advantages that: the utility model discloses can block the inside that the rainwater got into the aircraft from the rudder pivot, reduce the corrosion of aircraft structure, improve flight safety.
