Problems solved by technology

[0003] The disadvantage of this arrangement is that the movable element, for example in the form of a freely adjustable inlet or outlet flap, is subjected to high mechanical loads during flight, especially when it is in the position of opening a reduced flow cross-section
Furthermore, with a reduced flow cross-section setting for the supply of ambient air to the individual systems on demand, the movable elements can cause aerodynamic losses and increased noise during flight

Embodiment Construction

[0021] exist figure 1 and figure 2 , a ram air channel for supplying ambient air in the aircraft is shown, both designated by numeral 10 , having a first air inlet 12 . The first air inlet 12 is in the form of a NACA inlet and has a constant flow section, that is, the movable element in the area of ​​the first air inlet 12 is eliminated, such as an adjustable inlet sheet for setting the flow section of the first air inlet 12 pieces.

[0022] A main flow channel 16 extends from the first air inlet 12 along the outer wall 14 of the ram air channel 10 and ambient air flows through this main flow in the flow direction S during operation of the ram air channel 10 for supplying ambient air to the onboard systems. Channel 16. Downstream of the first air inlet 12 a first and a second diffuser 18 , 20 are provided in the main flow channel 16 .

[0023] Downstream of the second diffuser 20 , a side channel 22 branches off from the main flow channel 16 , which extends substantially ...

Abstract

A ram air channel (10) for the supply of ambient air in an aircraft includes a first air inlet (12) and a main flow channel (16) which extends downstream of the first air inlet (12). In order to guarantee that the systems on board the aircraft are supplied, in a simple and reliable way, with the required ambient air in any operational state of the aircraft, ie. both during the flight and on the ground, the ram air channel (10) has a second air inlet (24) which is independent from the first air inlet (12).

Description

technical field [0001] The invention relates to a ram air channel for ambient air supply in an aircraft, comprising a first air inlet and a main flow channel extending downstream of the first air inlet, and to a method for operating such a ram air channel. Background technique [0002] A ram air channel having an air inlet and a main flow channel extending downstream of the air inlet is used in modern aircraft to supply ambient air to various onboard systems, such as the air conditioning system. During flight, ambient air flows into the ram air passage through the air inlet, however when the aircraft is on the ground, the air flow through the air inlet is generated using mechanical means such as a syringe or the generation or active creation of low pressure within the ram air passage. Ambient air flow. To be able to adjust the flow of ambient air supplied through the ram air duct to the different needs of the systems being supplied with ambient air, depending on whether the...
