Abstract

This chapter presents conceptual studies to evaluate the performance of the propulsor and its associated vehicle in the configurations of wake ingestion (WI) and boundary layer ingestion (BLI). A power conversion analysis uses the so-called power balance method (PBM) to elaborate the power-saving mechanism of WI, showing that the Froude’s propulsive efficiency as a figure of merit should be separated from the power conversion efficiency in these configurations. The body/propulsor interaction occurring in the BLI configuration is qualitatively analysed to clarify its influence on the performance of the integrated vehicle. The results suggest that the minimization of power consumption should be used as a design criterion for aircraft utilizing BLI. This is different from the usual way of aircraft design which mainly focuses on minimizing the airframe drag.
