摘要:
The invention relates to an arrangement (1) that comprises a mobile plate (18) controlled by a means for fluid communication (23) between the outer (18A) and inner surfaces of the mobile plate (18), wherein said means is located at least in the vicinity of a limited downstream area (24) of said outer surface (18A), are at a high pressure when the aircraft flies at cruising speed, and are capable of transmitting said high pressure to an extended area (26) of said inner surface.

Disclosed is an air intake arrangement for an aircraft. The arrangement includes an air intake orifice, which is configured to bleed off a flow of external air, pass the external air through at least one air passage channel and ventilate a confined zone of the aircraft. An aerodynamically controlled shut-off means, comprised of a controllable mobile element and control means, is configured to regulate flow of the external air through the air passage channel to vary a cross section of the air passage channel relative to aircraft speed. The control means are arranged in the air passage channel and include an aerodynamic surface configured to apply a lift force to the control means to vary the cross section of the air passage channel as the flow of external air passes through the channel and toward the confined zone.
摘要:
An air intake arrangement includes a mobile plate controlled by at least one fluid communication passage or opening extending between the outer and inner surfaces of the mobile plate. The fluid communication passage or opening is located at least in the vicinity of a limited downstream area of the outer surface, is at a high pressure when the aircraft flies at cruising speed, and is capable of transmitting the high pressure to an extended area of the inner surface. The air flowing through the air intake arrangement may be used to refresh an enclosed area with electrical or mechanical equipment.

A bypass turbine engine includes a precooler having an annular cross-sectional shape about the axis of a pod and arranged inside the rear part of an inner shroud in contact with a cold fluid exiting a fan duct.
摘要:
The invention concerns an arrangement comprising at least one air passage channel (12) with an air vent (14), and designed to ventilate at least one confined zone (11) in an aircraft with fresh air entering upstream, through the air vent, in the channel and exiting downstream thereof towards the zone to be ventilated. The invention is characterized in that the cross-section of the air passage channel (12) is adjustable based on the speed and the altitude of the aircraft and the arrangement comprises therefor a membrane (19) elastically deformable under the action of a fluid control (18) to enable said channel cross-section to be varied.
摘要:
The invention concerns a ventilating air intake arrangement with mobile sealing device. The arrangement comprises at least one air passage channel (12) with an air vent (14), and is designed to ventilate at least one confined zone (11) in an aircraft with fresh air entering upstream, through the air vent, in the channel and exiting downstream thereof towards the zone to be ventilated. The invention is characterized in that the cross-section of the air passage channel (12) is automatically adjustable based on the speed and the altitude of the aircraft and the arrangement comprises therefor controllable mobile-element closing means (17) associated with the channel and for varying its cross-section.
