Conceptual Design,Evaluation and Research Identification for Remote Augmented Propulsive Lift Systems (Rals) with Ejectors for VTOL Aircraft.

摘要

Ejector concepts for use with a remote augmented lift system (RALS) exhaust nozzle were studied. A number of concepts were considered and three were selected as having the greatest promise of providing the desired aircraft and exhaust gas cooling and lift enhancement. A scale model test program is recommended to explore the effects of the more important parameters on ejector performance.
