Abstract

Air cooling unit and electrical heater are used to simulate temperature with wide range on Altitude Simulation Test Facility (ASTF) for reciprocating aeroengine, it is difficult to achieve controlling accurately. In this paper simulated temperature is divided into three segments of low, normal and high temperature and distinct strategies are applied to regulate temperature respectively. Based on the dynamical analysis and modeling of temperature change, research is performed on the regulating process for ASTF temperature system, and simulation results show that these strategies could satisfy the demand for speed and precision of temperature controlling. For the inlet temperature of airflow into reciprocating aeroengine through turbocharger, the mathematic relationship for heat transfer between turbocharger and intercooler is built.Simulating calculation on an example for engine in steady state at different altitude is carried out. The results present that calculation trend is consistent with the fact.
