| Title |
| The Coanda/Refraction Concept for Gas Turbine Engine Test Cell Noise Suppression |
| Scope |
| Document provides information on how military/commercial/gas turbine engine test cell/system users may benefit from this unique Coanda//refraction concept.<p>The information contains several factors which are considered essential for understanding the practical technical aspects of the concept. These are: a. operation need; b. concept definition; c. developmental program; and d. program results.<p>To present an advanced technology in suppression of gas turbine engine exhaust noise in ground run-up test cells/systems. The discussion herein is limited to turbojet and turbofan type engines, although the concept is equally applicable to turboshaft and turboprop types.<p>To explain specific applications of this technique in various types of test cells. |
