Fly-over noise measurements and simulation for a turboprop aircraft
The study of aircraft noise started in earnest in the 1960s, however, the validation of comprehensive noise models for existing commercial aircraft using well-defined experimental data have since produced modest advances. Considerable focus appears to have been placed on aircraft conceptual design, with relatively little effort considering aircraft currently in use, for which we believe there i...
متن کاملActive Noise Control in Propeller Aircraft
A noisy environment dominated by low frequency noise can often be improved through the use of active noise control. This situation arises naturally in propeller aircraft where the propellers induce periodic low frequency noise inside the cabin. The cabin noise is typically rather high, and the passenger flight comfort could be improved considerably if this level were significantly reduced. This...
متن کاملAiaa 2001-4374 a Lumped Parameter Model of Turboprop Aircraft Operating on Gravel Runways
The purpose of an aircraft Takeoff Performance Monitoring System (TOPMS) is to provide to the pilot information pertaining to the level of safety with which a takeoff is proceeding. The authors have developed a theoretical dynamic model to investigate the feasibility of using an observer system during the roll and takeoff phases of aircraft operation to provide to the pilot the information that...
متن کاملActive Control of Aircraft Cabin Noise
The noise levels in the passenger cabin of turbopropeller-driven aircraft are typically higher than the noise levels in comparable turbofan-powered aircraft. The sources of noise in a turboprop aircraft include boundary layer flow noise, structure-borne noise due to engine vibration, and acoustic excitation of the fuselage due to the propeller, with the latter being dominant for most turboprop ...
متن کاملActive Noise Control inside the Loadmaster Area of a Turboprop Transport Aircraft
The paper describes the design and test of a prototype active noise controller for a semienclosed cabin inside a turbo-prop aircraft. Here, the eight active noise control loudspeakers and sixteen microphones are mounted at the cabin walls and ceiling. For the development process, an acoustical mock-up is built to reproduce the acoustic situation inside the aircraft on the ground. The acoustic r...
