Pages : 109
Book Description
This volume is the first in a series of three volumes (AD-403 701 and AD-403 712) concerned with the physical aspects of noise control in aircraft engine test cells and ground run-up suppressors. This volume presents recommended procedures for the measurement of noise control effectiveness. Three classes of measurement procedures are described. The first class is concerned with the description of the acoustical effectiveness of a facility as a whole. Such descriptions may be used to compare facilities with one another or to determine if a facility has met a given criterion. The second class of measurements is used to determine the most economical way of improving the noise control design of an existing facility. The third class of measurements is used to describe the acoustical effectiveness of individual noise control components.

Influence of Noise Control Components and Structures on Turbojet Engine Testing and Aircraft Ground Operation

Pages : 114
Book Description
There has been a need for summarizing and establishing adequate aerodynamic and thermodynamic design criteria for turbojet engine test cells and ground run-up suppressors. These criteria are discussed and their uses are illustrated by examples of typical design problem solutions. The presence of noise suppression structures can have significant influences upon the operation of the turbojet engine. These influences are enumerated and evaluated with recommendations for establishing maximum acceptable effects. Typical test cell configurations are presented and design criteria are established for providing noise suppression facilities which may be utilized for testing a full size aircraft or an engine by itself. These facilities can be either permanent structures or portable units.
