FIELD: aircraft engineering. ^ SUBSTANCE: invention relates to process air production systems, particular by to those used in airplanes. Proposed system comprises first air cooling system with first hear exchanger and additional air cooling system to be built in the first one. Built-in cooling system comprises heat exchanger that is built in air duct, either upstream or downstream of airflow with respect to aforesaid first heat exchanger. The latter is mounted in heat rejection channel. ^ EFFECT: reduced weight and drag, easier mounting and operation. ^ 6 cl, 1 dwg |
