Proposition 1067 Advanced study for active noise control in aircraft

Objetivo

Initial assessments indicate that active noise control, the introduction of antinoise cancelling the original noise, has a promising potential for solving the critical low frequency interior noise problem of fixed wing and rotary wing aircraft.

The main goal of this project is to investigate this technique in greater detail and to identify feasible optimum active noise control systems for future practical applications.
The total project progressed extremely well. For the fixed wing aircraft group, for example, all laboratory and aircraft testing and all theoretical work could be performed as planned. In addition, the development of the two control units could be finished and finally very successfully flight tests as initially assumed. For the rotary wing aircraft group similar progress was made. Also in this group all experimental and theoretical work could be finished and successfully concluded in time.

The established results of the project by far exceeded the expectation. They are documented in more then hundred reports and range from detailed theoretical results to practically oriented laboratory and full scale flight test data of all research sub-areas considered. For the future several scientific papers are planned to be published explaining more details of these research results. Two summary reports on the project with selected data have been published already
Following an evaluation of pertinent active noise control work, detailed theoretical and experimental research is performed. The research covers interior noise calculations and noise and vibration measurements in aircraft in flight and in a full scale fuselage test section on the ground. Laboratory tests and investigations on promising new noise control transducers are included. Also, extensive work is performed on the development of optimum prototype active noise control systems. In the later phase of the study, these systems will be evaluated by ground and flight testing.

The study will advance the current technology in this field and provide a basis for improving the passenger comfort, important for the competitiveness of future European aircraft. In addition, a significant technology spin-off to other industrial branches can be expected.
