System and method for ventilating explosive regions of an aircraft

摘要

A system for ventilating an explosion hazard region of an aircraft includes a ram-air channel, which has an air inlet for feeding ambient air into the ram-air channel as well as an air outlet. The ram-air channel is devised to feed air to a device that is to be cooled on board the aircraft. A ventilation line has an air inlet for feeding air flowing through the ram-air channel into the ventilation line as well as an air outlet. The ventilation line is devised to feed air to a region of the aircraft that is to be ventilated. An accumulator is disposed between the ram-air channel and the air inlet of the ventilation line and is devised to convert the dynamic pressure of the air flow conveyed through the ram-air channel at least partially into static pressure for regulating flow through the explosion hazard region.

主权项

1. A ventilation system for ventilating a region of an aircraft, comprising:
a ram-air channel comprising:
an air inlet for feeding ambient air into the ram-air channel;an air outlet; anda ram-air channel wall,wherein the ram-air channel is configured to feed air to a device that is to be cooled on board the aircraft, andwherein an air flow in the ram-air channel flows in a direction substantially parallel to the ram-air channel wall a ventilation line comprising:
an air inlet for feeding a partial portion of the air taken from the air flow through the ram-air channel into the ventilation line;an air outlet,wherein the ventilation line is configured to feed air to the region of the aircraft that is to be ventilated; and an accumulator disposed between the ram-air channel and the air inlet of the ventilation line and also located to extend through the ram-air channel wall so as to divert the partial portion of the air into the accumulator from a remainder of air flow conveyed through the ram-air channel wherein the accumulator comprises an air scoop that is incorporated into and extends from the ram-air channel wall, wherein the accumulator is configured to convert a dynamic pressure of the diverted air at least partially into static pressure.
