Optimisation des opérations hivernales des pistes d'aéroports (O2HPA)

航空安全的一个重要方面是机场跑道的适当维护。事实上，所有类型的固体或液体污染物，从小坚果到厚厚的雪层，都可能导致致命的事故。这一研究项目特别侧重于冬季跑道的维护，特别是除冰产品。尽管后者的使用量非常大，以不同的稀释形式，甚至当它们被周围的其他流体污染时。因此，蒙特雷亚尔机场运营团队ADM联系了UQAC的防冰材料国际实验室AMIL，以更多地了解这些产品的性能，以便优化和减少使用量。这种减少将减少对环境的影响，减少对飞机某些部件的破坏性影响，并降低成本。然后，利马团队将进行一系列性能测试，其中一些测试已经得到业界的认可，另一些测试将专门针对该项目进行调整，对具有代表现场普遍情况的环境条件的除冰产品进行广泛和多样化的抽样。该项目将分为三个目标，第一个目标将侧重于根据天气条件开发产品分类网格，并对传播率进行实验和数值模拟。第二项研究将研究液态产品的化学污染可能产生的影响。最后一个目标是研究固体产品的储存条件，以减少损失。大多数实验将在利马气候室内进行，如有必要，将在ADM现场进行验证。该小组将由学生、气象专家、WPred Inc.、Nachur阿尔卑斯解决方案公司和ETS的一名结冰现象数值模拟专家组成。

An important aspect of aviation safety is the proper maintenance of airport runways. Indeed, all types of solid or liquid contaminants, from the small nut to the thick layer of snow can cause fatal accidents. This research project focuses specifically on the maintenance of winter runways specifically on deicing products. Although the latter are used in very large quantities, in different dilution forms or even, when they are contaminated by other surrounding fluids. The Montréal airport operations team, ADM, therefore contacted the UQAC's Anti-Icing Materials International Laboratory, AMIL, to gain more knowledge about the performance of these products in order to optimize and reduce the amount used. This reduction will reduce their environmental impact, their damaging impact on certain parts of aircraft and the costs. The LIMA team will then perform a series of performance tests, some of which are already recognized by the industry and others that will be specifically adapted for this project with a wide and varied sampling of deicing products with environmental conditions representative of those prevailing in the field. The project will be divided into 3 objectives, the first of which will focus on the development of a classification grid of products according to the weather conditions coupled with an experimental and numerical simulation of the spreading rates. The second will study the possible effects of chemical contamination of liquid form products. The last objective will study storage conditions for solid-type products in order to reduce losses. Most of the experiments will be done inside the LIMA climate chambers and will be validated, if necessary, at the ADM site. The team will be supplemented by students, meteorological experts, WPred Inc., Nachurs Alpine Solutions and an expert in numerical simulation of icing phenomena from the École des technologies Supérieures, ETS.
