项目摘要

Aircraft icing is one of the most serious weather hazards to aircraft operation in cold weathers. Ice accretion over airframe surfaces can make the aircraft to roll or pitch uncontrollably, and even cause crashes. While a number of systems have been developed for aircraft icing mitigation, current anti-/de-icing strategies suffer from various drawbacks, including being too complex, too heavy or draw too much power to be effective. One promising method to resolve these issues is to utilize plasma actuation for aircraft anti-/de-icing operation. The principal aim of this project is to investigate the underlying physics of plasma discharges interacting with different substances (i.e., air, water and ice) associated with ice accretion process for the development of a new class of strategies for aircraft icing mitigation. The project will also encompass significant educational activities, including a multi-year graduate/undergraduate research program, development of new teaching modules, and an outreach program for local K-12 students, especially those from groups underrepresented in STEM fields, to inspire them to participate in science and engineering studies.The goal of this proposed research is to conduct a fundamental study to characterize the effects of Dielectric-Barrier-Discharge (DBD) plasma actuation on the coupled unsteady heat and mass transfer during the dynamic ice accretion process. The research tasks include: 1) conduct a fundamental study to characterize the thermodynamic characteristics of DBD plasma actuations under frozen-cold ambient temperatures pertinent to aircraft icing phenomena; 2) examine dynamic interactions between DBD plasma discharges with liquid water and solid ice to gain further insights into the fundamental mechanisms; 3) characterize the effects of the DBD plasma actuation on the coupled unsteady heat and mass transfer over ice accreting airfoil/wing surfaces; 4) explore/optimize design paradigms for the development of innovative, effective, DBD-plasma-based anti-/de-icing strategies for aircraft icing mitigation. In comparison with conventional anti-/de-icing methods, DBD-plasma-based anti-/de-icing approach could have significant advantages, including i) more efficient heating mechanism; ii) faster response time; and iii) lower operation power consumption for anti-/de-icing operation. The research would significantly improve our understanding about the important micro-physical thermal/mass transport processes, which could lead to the development of a new class of DBD-plasma-based, anti-/de-icing strategies to ensure safer and more efficient aircraft operation in cold weathers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

飞机结冰是寒冷天气下飞机运行最严重的天气危害之一。机身表面积冰会使飞机无法控制地滚动或俯仰，甚至导致坠机。虽然已经开发了许多用于飞机防冰的系统，但当前的防/除冰策略存在各种缺点，包括太复杂、太重或消耗太多功率而无法有效。解决这些问题的一种有前景的方法是利用等离子体驱动进行飞机防冰/除冰操作。该项目的主要目的是研究等离子体放电与积冰过程相关的不同物质（即空气、水和冰）相互作用的基本物理原理，以开发一类新型的飞机防冰策略。该项目还将涵盖重要的教育活动，包括多年研究生/本科生研究计划、新教学模块的开发以及针对当地 K-12 学生（尤其是来自 STEM 领域代表性不足群体的学生）的外展计划，以激励他们参与科学和工程研究。这项拟议研究的目标是进行一项基础研究，以表征介质阻挡放电 (DBD) 等离子体驱动的影响动态积冰过程中耦合的非稳态热质传递。研究任务包括：1）进行基础研究，以表征与飞机结冰现象相关的冰冻环境温度下 DBD 等离子体驱动的热力学特性； 2) 检查 DBD 等离子体放电与液态水和固体冰之间的动态相互作用，以进一步了解基本机制； 3) 表征 DBD 等离子体驱动对积冰翼型/机翼表面耦合非稳态传热和传质的影响； 4) 探索/优化设计范例，以开发创新、有效、基于 DBD 等离子体的防/除冰策略，以减轻飞机结冰。与传统的防/除冰方法相比，基于DBD等离子体的防/除冰方法具有显着的优势，包括i）更高效的加热机制； ii) 更快的响应时间； iii) 降低防冰/除冰操作的运行功耗。这项研究将显着提高我们对重要的微观物理热/质量传输过程的理解，从而可能导致开发出一种新型基于 DBD 等离子体的防/除冰策略，以确保飞机在寒冷天气下更安全、更高效地运行。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
