边界层吸入式进气道气动设计及流动控制技术研究进展
Research progress on aerodynamic design and flow control technologies for boundary layer ingestion inlets
摘要
Abstract
Boundary-Layer-Ingesting(BLI)propulsion technology uses a rear mounted engine to draw in the bound-ary layer on the fuselage,reducing the airflow velocity at the inlet of the intake duct and the outlet of the propulsion system,thereby achieving efficient flight of the aircraft.Compared to traditional propulsion systems,BLI propulsion systems have the potential to significantly reduce fuel consumption,flight resistance,and pollution emissions,and are a key development direction in the field of aircraft and engine integration in the future.As a specific practitioner of boundary layer ingesting,the performance of the BLI inlet directly affects the comprehensive benefits of the entire BLI propulsion system compared to traditional propulsion systems.Since its emergence,it has attracted widespread atten-tion from scholars and research institutions at home and abroad.Based on this,this article provides an overview of the research background and progress of BLI intake duct technology,with a focus on discussing the aerodynamic design methods,research methods,internal flow mechanism,and internal flow control technology of BLI intake ducts.Fi-nally,based on the analysis and summary of the current research status at home and abroad,the future development of BLI intake duct is discussed.关键词
