Report discusses use of coupled aerodynamic/ and acoustical computer codes to predict noise emitted by turbopropeller blades turning at supersonic tip speeds. To predict noise field, existing turboprop-noise computer code by Farassat modified to accept blade-pressure inputs from three-dimensional turbofan aerodynamical computer code by Denton.
