House prices, airport location proximity, air traffic volume and the COVID-19 effect
作者: Ngo   Thanh     Squires   Graham     McCord   Michael     Lo   Daniel   来源: Regional Studies, Regional Science 年份: 2023 文献类型 : 期刊 关键词: amenities   activity   cities   air   prices   house   airports   traffic  
描述: Although house prices and airports are influenced by distinct factors that shape their evolutions, they are also intrinsically connected through the natural and built environment. Standard theory suggests that air-traffic noise and proximity to key economic hubs such as airports are of prime importance to house prices and the housing market. This study contributes to understanding the link between the housing market, airport location proximity and air traffic. The research investigates this association across four key urban areas within New Zealand proximal to an international airport: Auckland, Wellington, Christchurch and Queenstown. Applying a generalized least squares (GLS) regression approach, the analysis reveals that house prices, air-traffic activity and proximity to airports within New Zealand demonstrate a statistically significant effect, and that air traffic volume has a positive effect on house prices. Moreover, the findings reveal a ‘U’-shape relationship between distance to the airport and house prices, suggesting that airport noise and pollution adversely affect house prices, with this effect diminishing with distance, indicating that economic influences and employment may also serve as a positive externality.

High AOA decoupling control for aircraft based on ADRC
作者: LIU   Junjie   SUN   Mingwei   CHEN   Zengqiang   SUN   Qinglin   来源: Journal of Systems Engineering and Electronics 年份: 2020 文献类型 : 期刊 关键词: disturbance   allocation   linear   attack(AOA)   decoupling   active   control   observer(LESO)   technology   rejection   extended   high   of   thrust   angle   state   control(ADRC)   Vector  
描述: In this paper, a practical decoupling control scheme for fighter aircraft is proposed to achieve high angle of attack(AOA)tracking and super maneuver action by utilizing the thrust vector technology. Firstly, a six degree-of-freedom(DOF) nonlinear model with 12 variables is given. Due to low sufficiency of the aerodynamic actuators at high AOA, a thrust vector model with rotatable engine nozzles is derived. Secondly, the active disturbance rejection control(ADRC) is used to realize a three-channel decoupling control such that a strong coupling between different channels can be treated as total disturbance, which is estimated by the designed extended state observer. The control surface allocation is implemented by the traditional daisy chain method. Finally,the effectiveness of the presented control strategy is demonstrated by some numerical simulation results.

基于MATLAB/Simulink软件实现对航空电源车直流升压不成功故障快速分析
作者: 庄新闯   李威   蒋超   拾华杰   来源: 电工技术 年份: 2022 文献类型 : 期刊 关键词: 升压装置   航空电源车   12脉波整流  
描述: 针对航空电源车在保障飞机开车过程中出现的直流升压不成功的事故案例,通过分析故障电源车保障的飞参数据,判定事故由直流升压装置故障导致。采用MATLAB/Simulink软件对直流升压装置中的串联12脉波整流电路及其可能出现的故障情况进行仿真以及定量分析。仿真和计算的结果表明,当12脉波整流电路非同相位的2个二极管损坏时,其输出特性与事故案例相同,成功排查出故障位置。
