SAE AIR1191A
Performance of Low Pressure Ratio Ejectors for Engine Nacelle Cooling
STANDARD published on 1.3.1999
The information about the standard:
Designation standards: SAE AIR1191A
Publication date standards: 1.3.1999
SKU: NS-477048
Country: American technical standard
Category: Technical standards SAE
Annotation of standard text SAE AIR1191A :
A general method for the preliminary design of a single, straight-sided, low subsonic ejector is presented. The method is based on the information presented in References 1, 2, 3, and 4, and utilizes analytical and empirical data for the sizing of the ejector mixing duct diameter and flow length. The low subsonic restriction applies because compressibility effects were not included in the development of the basic design equations. The equations are restricted to applications where Mach numbers within the ejector primary or secondary flow paths are equal to or less than 0.3.
SUBJECT TAXONOMY: Cooling, Engine cooling systems, Hybrid engines, Rotary-wing aircraft
