Design and Analysis of a Turbojet Anti-ice System

In this paper, an anti-ice system for a turbojet is designed. Speed, altitude, ambient temperature and moisture content of the air are considered in the design. Critical conditions, in which icing is expected, are determined. Capture region, where ice formation is most probable, is investigated and protected by hot air from compressor exit. A control system based on PID controller is designed to control the flow rate of the hot air. In this design, surfaces like lip, bullet nose, and struts are protected against ice formation.
