Abstract:A large amount of gases need to be introduced into the aircraft Environmental Control System (ECS) from the engine compressor during flight. The gases at high temperature and pressure usually contain lots of dust particles which should be removed. The cyclone dust collector involved in this paper is a new type of "no sieve" dust collector which could proudce rotational flow with staionary guid vane. Depending on its unique structure, the cyclone dust collector can separate dust particles from airflow due to the density defference between them. Its own geometric parameters have great influence on the dust removal performance. With numerical simultion method, this article analyzes the influence of the guide vane, collection cavity and separate channel on the dust removal efficiency and flow resistance, which plays a very important role in structural design of dust collector for bleed air system of ECS. © 2018 IET Conference Publications.
