1.	Small diameter and high velocity jet will produce _____________(a) more noise(b) less noise(c) less aural signature(d) independent of diameter and velocityI had been asked this question by my college professor while I was bunking the class.My question is from Configuration Layout Considerations topic in division Configuration Layout Considerations of Aircraft Design
Answer» The CORRECT answer is (a) more noise To explain: in a typical aircraft, engine is primary component which generates higher aural SIGNATURES. SMALL diameter and high exhaust will generate more noise DUE to the EFFECT of air shear layers.
