2. Academic Direction
1)Overall design and Multidisciplinary Optimization Design (MOD) of aircraft engine
Investigation on object-oriented overall performance prediction technology of aircraft engine, multidisciplinary design andoptimizationtechnology, variable cycle engine technology,intercooled recuperated cycle enginetechnology etc. are performed, the object-oriented overall performance prediction and analysis software of aircraft engine are developed, and has been successfully applied in power research institute, turbine institute of AVIC.
2)Design technology of Turbine-Based Combined-Cycle (TBCC) engine used for hypersonic aircraft
Overall design and cycle parameters matching of series and parallel TBCC, hypersonic aircraft / TBCC engine integrated performance prediction and experiment of small-scaled series TBCC engine are executed, The TBCC test rig is established which is unique in domestic colleges and universities.
3) Unsteady flow mechanism in turbomachinery flow
Unsteady prediction method based on modified time-inclined algorithm is developed to simulate the flow filed in turbomachinery. Breakthroughs are obtained on CFD method, flow mechanism and optimization design in turbomachinery filed, and technical approach can be provided for the design.
4) Novel exhaust system design and infrared radiation characteristics prediction
Design technology of S-shaped nozzle with low detectable characteristics, designtechnology of three bearing deflection nozzle, design technology of nacelle used for large turbofan engine, CFD simulation technology of thrust reverser flowfield of turbofan engine and infrared radiation characteristics prediction of exhaust system are investigated. The developed nacelle design software has been successfully applied in the nacelle design process of one large-scaled transport plane. The model experiment under thermal condition is firstly carried out in China for three bearing deflection nozzle used in short takeoff / vertical landing aircraft.
5)CFD investigation and experimental verification technology of new flow control pattern
Systematic CFD and experimental investigation are performed on fixed geometry vectoring nozzle technology and blockerless thrust reverser technology. The first complete experimental data set is established in China for SVC nozzle, the matching relationship between fixed geometry vectoring nozzle and engine is solved for the first time in whole engine environment.
