Description:The Unified AeroAcoustic Program (UAAP) code calculates the airloads on a single rotation prop-fan, or propeller, and couples these airloads with an acoustic radiation theory, to provide estimates of near-field or far-field noise levels. The steady airloads can also be used to calculate the nonuniform velocity components in the propeller wake. The airloads are calculated using a three dimensional compressible panel method which considers the effects of thin, cambered, multiple blades which may be highly swept. These airloads may be either steady or unsteady. The acoustic model uses the blade thickness distribution and the steady or unsteady aerodynamic loads to calculate the acoustic radiation. The users manual for the UAAP code is divided into five sections: general code description; input description; output description; system description; and error codes. The user must have access to IMSL10 libraries (MATH and SFUN) for numerous calls made for Bessel functions and matrix inversion. For plotted output users must modify the dummy calls to plotting routines included in the code to system-specific calls appropriate to the user's installation. Menthe, R. W. and Mccolgan, C. J. and Ladden, R. M. Unspecified Center AEROACOUSTICS; AERODYNAMIC NOISE; AIRCRAFT NOISE; HIGH SPEED; PROP-FAN TECHNOLOGY; PROPELLER FANS; TURBOPROP AIRCRAFT; USER MANUALS (COMPUTER PROGRAMS); AERODYNAMIC LOADS; BESSEL FUNCTIONS; MATRICES (MATHEMATICS); NOISE INTENSITY; PANEL METHOD (FLUID DYNAMICS); PLOTTING; SOUND WAVES; UNSTEADY AERODYNAMICS; VELOCITY DISTRIBUTION...We have made it easy for you to find a PDF Ebooks without any digging.
