An aircraft ram air channel assembly having: a first ram air inlet with a deflector protruding from the aircraft outer skin, the deflector guiding an air flow into a first ram air inlet channel; a second ram air inlet having a cross-sectional area flush with the outer skin, the second inlet being coupled to a second ram air inlet channel and arranged proximate to the first inlet upstream of the first inlet; and a flap pivotable about an axis between first and second operating positions. The axis is upstream of the first and second inlets and extends perpendicular to the air flow. The flap in its first position projects into the second inlet channel to control air flow through the second inlet into the second inlet channel, and in its second position projects into the air flow to prevent foreign objects from entering the first and second inlets.

Ram air channel assembly and method for operating a ram air channel assembly

A mixer assembly for an air-conditioning system comprising a recirculation air line, connectable to a vehicle region to be air-conditioned, to remove recirculation air from the region, and an air-conditioning air line, connectable to an air-conditioning unit to remove conditioned air from the air-conditioning unit. A first mixing region, for mixing the recirculation air with the conditioned air, is connected to the two air lines. A second mixing region, for mixing the first mixing region air with recirculation air, is connected to the recirculation air line and the first mixing region. Also, a first supply line is connected to the first mixing region to supply air from the first mixing region to a first partial region of the vehicle region, and a second supply line is connected to the second mixing region to supply air from the second mixing region to a second partial region of the vehicle region.

Mixer assembly and method for operating a mixer assembly

A mixing device for an aircraft air conditioning system includes a plurality of cold-air supply lines, which are devised to supply cold air to the mixing device. A plurality of warm-air supply lines is further provided, which are devised to supply warm air to the mixing device. A first premixing chamber is connected to the cold-air supply lines and devised to mix the cold air that is fed through the cold-air supply lines into the first premixing chamber. A second premixing chamber is connected to the warm-air supply lines and devised to mix the warm air that is fed through the warm-air supply lines into the second premixing chamber. Finally, a main mixing chamber is connected to the first and the second premixing chambers and devised to mix the cold air premixed in the first premixing chamber with the warm air premixed in the second premixing chamber.

Mixing device for an aircraft air conditioning system

A mixer for an aircraft air conditioning system has first and second fresh air lines and first and second recirculation air lines. A first premixer is connected to the first fresh air line and the first recirculation air line, to mix the fresh air with the recirculation air thereof. A second premixer is connected to the second fresh air line and the second recirculation air line, to mix the fresh air with the recirculation air thereof. A main mixer is connected by a first premixed air line to the first premixer and by a second premixed air line to the second premixer. The main mixer is adapted to be supplied through the first premixed air line and the second premixed air line exclusively with premixed air from the first and/or the second premixer.

Mixer assembly for an aircraft air conditioning system

An aircraft air-conditioning system includes an air-conditioning unit that is connected by a main fresh-air line to a mixer in order to supply the mixer with fresh air at a desired low temperature. A fresh-air branch line that is connected upstream of the mixer to the main fresh-air line has a flow cross section that is smaller than a flow cross section of the main fresh-air line. In a region of connection of the main fresh-air line to the fresh-air branch line the main fresh-air line and the fresh-air branch line are so formed that a main fresh air flow flowing through the main fresh-air line is deflected, while a fresh air branch flow flowing through the fresh-air branch line experiences substantially no deflection.
