Problems solved by technology

[0009] The opposing performance levels of these two types of overvoltage gates make it impossible to obtain an overvoltage gate that is effective in all operating conditions
In addition, "transverse" type doors create an obstruction to the external flow, creating a suction effect

Embodiment Construction

[0036] The present invention involves such as figure 1 and 2 An axial overpressure door 1 for an aircraft is shown schematically. This overpressure door 1 comprises a hatch 2 comprising an inner surface 2A and an outer surface 2B and is pivotable about an axis of rotation 4 via a standard hinge 5 relative to a compartment 6, only a part 7 of the outer wall of the compartment 6 being Shows. The hatch cover 2 can be in the closed position (in figure 2 indicated in ) and open position (in figure 1 indicated in ) to pivot between. Since said overpressure door 1 is of the axial type, the axis of rotation 4 is aligned (within limits) with the external flow generated by the relative movement of the aircraft in the air during flight. The external stream is in figure 1 Indicated by arrow E. Thus, the directions of the flow E and the axis of rotation 4 are substantially parallel.

[0037] This overpressure door 1 is thus mounted on the cabin 6 of the aircraft or of the aircr...

Abstract

The overpressure door, of axial type, includes a hatch configured to pivot about an axis between a closed position and an open position and an aerodynamic appendage securely attached to the hatch. The aerodynamic appendage makes it possible to produce a deflection of the external flow in the open position of the hatch of the door.

Description

technical field [0001] The invention relates to an axial type overpressure door of an aircraft, an aircraft cabin and an aircraft provided with such a door. [0002] More specifically, the present invention relates to overpressure doors installed on partially or completely airtight compartments of aircraft that are subject to air under pressure (air under pressure) leakage. The overpressure door is arranged in the area of ​​the aircraft or an engine of the aircraft where high-pressure air can escape from the cabin by opening the overpressure door. In particular, such an overpressure door comprises a hatch which is pivotable about an axis between a closed position and an open position. Typically, said hatch (initially closed) opens when the differential pressure between the inner and outer surfaces exceeds a given threshold. Background technique [0003] The object of the invention is to improve the aerodynamic efficiency of such an overpressure door. [0004] It is known ...
