Blended-wing-body Configuration Aerodynamic Interference of Airframe-power Plant with Air Intake and Exhaust Effects
高气动效率是翼身融合布局获得竞争优势的关键因素.为有效抑制动力装置对该布局气动效率的不利干扰,需对适用于翼身融合布局的动力装置布置形式进行深入研究.本文采用计算流体力学(CFD)技术和可计及进排气影响的动力短舱模型,对某翼身融合—背撑发动机构型进行了精细内、外流耦合数值模拟,研究了巡航点附近动力装置和翼身融合机体之间的气动干扰特征.研究结果表明,相对于孤立翼身融合体构型,全机构型的翼身融合体部件升力系数大幅降低,阻力显著增大,短舱溢流在机身上形成…查看全部>>
High aerodynamic efficiency is a critical advantage of blended-wing-body configuration compared to other next generation civil transport aircraft configurations.In order to maintain this advantage,lots of efforts should be taken to construct power plant layout suitable to blended-wing-body configuration which decrease the harmful effect of aerodynamic interference between airframe and engine.In this paper,high reliability CFD technology and TPS(Turbine Propu…查看全部>>
