Abstract
An air intake for an aircraft forms a first airflow channel () for feeding fresh air into the aircraft, and a second airflow channel () for feeding cooling air to an auxiliary power unit (AP). These first and second airflow channels are so positioned relative to each other that respective channel inlets or flow cross-sectional areas can be opened and closed by a single seesaw rocker () which is journaled or hinged between its ends to the aircraft body in such a position that one end (A) of the seesaw rocker () can close the first channel () while the other rocker end (B) simultaneously closes the second channel (). The seesaw rocker () is driven by a motor responsive to the operation of the auxiliary power unit. When the auxiliary power unit operates, both channels () are open. When the auxiliary power unit does not operate both channels () are closed.
