摘要：
The application of a three-dimensional, full-potential, finite-element method, TRANAIR, to the installation of turbofan engines on transport configurations is presented. An extension of the method, whereby regions of different total pressures and temperatures are modeled to simulate engine exhaust flows, is explained. This extension allows a transonic flow analysis of the mutual interference between turbofan exhaust flows and the nearby airframe. Computational results and comparisons with experiment are presented to illustrate the abilities of TRANAIR to adequately represent these complex geometry and flow phenomena. Results are presented for two isolated nacelles and three installed engine/airframe combinations. Comparisons of computed results with test data show good agreement. © 1989 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.
