Aerodynamic Calculation and Computer Numerical Simulation Methods Applied in Jet Engine Research

Abstract

The development status of aero-engines is a sign of a country's technological development level and comprehensive national strength. Jet engines undergone a rapid development since being invented and are widely applied in both commercial and military aircraft nowadays. The objective of jet engines is to provide thrust for aircraft and maintain high performance in different flight segments. Engine design choice must be compromised to balance different selection criteria. This article reviews the development history of jet engines and reviews the development paths of jet engines in various technical fields in detail. It also summarizes the current state and development of jet engines from the civil and military fields and finally looks forward to the future development of jet engines.  The discussion of several publications shows that considerable attention has been paid in reducing emissions, increasing fuel efficiency and reducing noise. Advanced manufacturing technologies and materials could improve engine performance. Establish new operations could be another future direction while it has limitations. Bio-fuel could be a promising solution in reducing emissions while its feasibility in meeting real operating conditions still need to be investigated.
