The DGEN 380 is a small, separate-flow, geared turbofan being promoted for a small twinjet application in the emerging personal light jet market. Smaller, and producing less thrust than other entries in the industry, the engine could be applied to a four to five place twinjet designed to compete in an area currently dominated by propeller-driven airplanes. This paper documents the procedures used to project static noise measurements collected from the engine to flight conditions and the prediction of certification noise of a notional airplane powered by twin DGEN engines. A novel noise model calibration technique and a Monte Carlo uncertainty experiment are emphasized.
