TL;DR: The results of social surveys conducted near three airports that support both general aviation and scheduled air carrier operations are presented and discussed and conclusions are made.
Abstract: The results of social surveys conducted near three airports that support both general aviation and scheduled air carrier operations are presented and discussed. Inferences supported by these data include: (1) The nature of noise exposure and community reaction at smaller airports may differ from that at larger airports; (2) survey techniques are capable of identifying changes in annoyance associated with numerically small changes in noise exposure; (3) changes in the prevalence of annoyance are causally produced by changes in noise exposure; and (4) changes in annoyance associated with changes in exposure vary with time.

TL;DR: In this paper, the authors auralize flyover noise from the reference aircraft and the best hybrid wing-body configuration using source noise predictions and shielding data based largely on the earlier assessments.
Abstract: System noise assessments of a state-of-the-art reference aircraft (similar to a Boeing 777-200ER with GE90-like turbofan engines) and several hybrid wing–body aircraft configurations were recently performed using NASA engine and aircraft system analysis tools. The hybrid wing–body aircraft were sized to an equivalent mission as the reference aircraft and assessments were performed using measurements of airframe shielding from a series of propulsion airframe aeroacoustic experiments. The focus of this work is to auralize flyover noise from the reference aircraft and the best hybrid wing–body configuration using source noise predictions and shielding data based largely on the earlier assessments. Here, auralization refers to the process by which numerical predictions are converted into audible pressure time histories. It entails synthesis of the source noise and propagation of that noise to a receiver on the ground. For each aircraft, three flyover conditions are auralized. These correspond to approach, sid...

TL;DR: In this paper, an airline network design model for minimizing airline operating costs is proposed to determine optimal air routes and flight frequencies, as well as types of aircraft, in response to airport noise charges.
Abstract: Noise charges have been introduced at major airports to mitigate external noise. This research investigated airline network design, by considering aircraft noise charges, and analyzing the performance of airport noise charge policies, from multiple perspectives. We formulated an airline network design model for minimizing airline operating costs, to determine optimal air routes and flight frequencies, as well as types of aircraft, in response to airport noise charges. We further assessed the performance of different noise charge policies by evaluating changes in airport operating profits and the social cost to residents surrounding the airport. An empirical example, using the Chiang Kai-Shek International Airport, illustrates how airports should determine optimal noise charge policies, from different perspectives. The results show that airlines may adjust types of aircraft, flight frequencies and flight routes, in response to hub airport noise charge policies, which may lead to changes in social costs, airport revenues, and weekly aircraft schedules. Landing fees setting may, in addition, affect the control an airport has over social costs, due to noise surcharges.

TL;DR: In this paper, a method has been developed that estimates the overall change in fuel consumption and engine noise caused by modifications to an aircraft design and determines adjustments to the cruise performance based on changes in the engine components, the installation system, and system weight.
Abstract: The Silent Aircraft Initiative produced an aircraft design that combined many new and novel technologies to give a solution that was predicted to be fuel-efficient as well as extremely quiet. The study presented in this paper seeks to assess the benefits and penalties of each of the proposed technologies. A method has been developed that estimates the overall change in fuel consumption and engine noise caused by modifications to an aircraft design. The method sizes a propulsion system for a specified design and determines adjustments to the cruise performance based on changes in the engine components, the installation system, and system weight. The offdesign performance is also calculated so that the noise can be estimated. The method has been applied to show what contribution each silent aircraft technology made to the overall goal of the project. It also shows the tradeoffs between noise and fuel consumption for various technologies and indicates that there are configurations that can achieve both lower fuel burn and lower engine noise. The method has been used to identify a low-risk configuration of the silent aircraft, for which a new design is presented.
