Comparison of Semi-Empirical Noise Models with Flyover Measurements of Operating Aircraft

Vieira, A.E. (author), von den Hoff, B. (author), Snellen, M. (author), Simons, D.G. (author)

The contribution of the engine and the airframe to the total noise generated by an aircraft varies with the operating conditions. Semi-empirical models are able to account for such variations but require detailed engine and airframe data as input that is not readily available for most aircraft types and operations. This hinders the validation of...

Aero-acoustic response of an acoustic liner

Bouman, Gijs (author)

In this thesis, the resistance of a single degree of freedom liner is investigated experimentally. Semi-empirical resistance modelling fails at higher Mach numbers (M₀>0.3) and sound pressure levels (SPL>130dB), and experimental work is missing in these conditions. An experiment combining in-situ impedance measurements and phase...

Improving Capabilities in Modeling Aircraft Noise Sources

Vieira, A.E. (author)

Today's globalized world depends on civil air transportation, which has been continuously growing over the last decades. Nevertheless, the sustainability of this expansion is a challenge due to environmental problems. Along with greenhouse gas emissions, noise represents a severe hazard for human health, and consequently, noise regulations limit...

Flexible Runway Scheduling for Complex Runway Systems: A Multi-Objective Optimization for Fuel Use and Noise Disturbance at Amsterdam Airport Schiphol

Abbenhuis, Anthonie (author)

The runway usage of complex airports with multiple runways is currently prescribed by a preference list. The preference list mostly focuses on minimizing noise and it provides a more manageable flow for ATC. However, it does not consider the fuel burn or current demand of flights. This study presents a MILP scheduling model which optimizes for...

A multilevel optimization framework for aircraft operations on near-airport communities: Minimizing noise impact and fuel consumption

Ho-Huu, V. (author)

With a significant impact on the development of the global economy and society, air transport is predicted to rapidly grow in the coming years. Unfortunately, while delivering positive global economic and social benefits, air transport has also generated an adverse influence on the environment, especially on the quality of life of communities...

Assessment of the use of global optimisation techniques for aircraft noise source identification

von den Hoff, Bieke (author)

Over the past years, noise nuisance around airports strongly increased resulting in the need for aircraft noise reduction. Therefore, the noise sources should be known. This thesis assesses a new acoustic imaging method to identify sources on aircraft fly-over measurements. The proposed Global Optimisation (GO) algorithm is based on the theory...

Using NOMOS measurements to assess improvements of ECAC Doc. 29 aircraft noise calculations

Koster, Robert (author)

The amount of air traffic worldwide is increasing, with an adverse effect on aircraft noise in the vicinity of airports as a result. Measurements and calculations have complementary benefits and limitations for the assessment of aircraft noise. A common method for the calculation of aircraft noise is ECAC Doc. 29. Various improvements of this...

An optimization framework for route design and allocation of aircraft to multiple departure routes

Ho-Huu, V. (author), Hartjes, S. (author), Visser, H.G. (author), Curran, R. (author)

In this article, we present the development of a two-step optimization framework to deal with the design and selection of aircraft departure routes and the allocation of flights among these routes. The aim of the framework is to minimize cumulative noise annoyance and fuel burn. In the first step of the framework, multi-objective trajectory...

Dutch Aircraft Noise Model: Classification comparison with measurements

Hooijmeijer, Davey (author)

In this thesis research, dutch aircraft noise model (NRM) calculations are compared to measurements to analyze the aircraft classification used in the model. To do so, a new implementation of the model has been set up to calculate with LVNL trackdata and NOMOS measurement data. First, the classification approach is analyzed as prescribed, which...
