Modelling landing gear noise with installation effects
Modelling landing gear noise with installation effects
This paper describes continued development and validation of a semi-empirical model of
the aerodynamic noise generated by aircraft landing gears at approach. The model has been
developed with Airbus funding over a number of years1,2 , but recent studies carried out as
part of the EC funded SILENCER project have led to the introduction of a number of new
effects that occur on aircraft in flight. The core of the noise model is based on nondimensional
source spectra derived from a database of full-scale tests on landing gears
installed in the DNW wind tunnel. The new installation effects have been derived using the
results of small-scale model tests3 and by analysis of flight test data4. The model is used to
examine differences between the performance of noise control fairings installed on a landing
gear in a wind tunnel and similar fairings installed on a real aircraft in flight.

Abstract
This paper describes continued development and validation of a semi-empirical model of
the aerodynamic noise generated by aircraft landing gears at approach. The model has been
developed with Airbus funding over a number of years1,2 , but recent studies carried out as
part of the EC funded SILENCER project have led to the introduction of a number of new
effects that occur on aircraft in flight. The core of the noise model is based on nondimensional
source spectra derived from a database of full-scale tests on landing gears
installed in the DNW wind tunnel. The new installation effects have been derived using the
results of small-scale model tests3 and by analysis of flight test data4. The model is used to
examine differences between the performance of noise control fairings installed on a landing
gear in a wind tunnel and similar fairings installed on a real aircraft in flight.
