Abstract
A cool air supply system includes a cool air inlet to a cabin of an aircraft fed with air cooled in a heat exchanger swept by a flow of external air from a static air inlet of the aircraft. The system further includes an ejector assembly for circulating external air in the exchanger. The ejector assembly includes a nozzle fed with air from the cabin of the aircraft via a cabin air outlet.
Claims18
A cool air supply system for supplying an aircraft with cooled air, said cool air supply system comprising
- a heat exchanger swept by a flow of external air from a static air inlet of the aircraft, and
- an air ejector causing circulation of said external air to said heat exchanger, said air ejector including a nozzle fed with air directly from a cabin of the aircraft via an air outlet in said cabin.
A cool air supply for a cabin of an aircraft, said cool air supply comprising;
- a static air inlet of the aircraft for receipt of external air;
- an outlet of the aircraft leading to an exterior of the aircraft;
- an air pipe connecting the static air inlet to the outlet of the aircraft;
- a heat exchanger located in said air pipe for receiving air from an engine of the aircraft;
- an air ejector located in said air pipe, said air ejector being directly fed with air from the cabin and said air ejector releasing air fed directly from the cabin into said air pipe for causing circulation of external air to the heat exchanger;
- and
- a cabin air inlet fed with air cooled by the heat exchanger.
A cool air supply for a cabin of an aircraft, said cool air supply comprising:
- a static air inlet of the aircraft for receipt of external air;
- an outlet of the aircraft leading to an exterior of the aircraft;
- an air pipe connecting the static air inlet to the outlet of the aircraft;
- a heat exchanger located in said air pipe for receiving air from an engine of the aircraft and for directing cool air to an inlet of the cabin;
- an air ejector located in said air pipe downstream from said heat exchanger;
- an air outlet from the cabin;
- and
- a valve for directing air flow from the air outlet of the cabin directly to the air pipe or an exterior of the aircraft so that when said air flow from the air outlet of the cabin is directly directed to said air pipe, external air is caused to be circulated to the heat exchanger.
