项目摘要
The aviation sector faces an enormous challenge to reduce its environmental impact, in particular its impact on climate change. In order to achieve this, the energy efficiency of aircraft must be maximized and the dependence on fossil fuels must be rapidly reduced. This collaboration between the University of Toronto and Bombardier concentrates on the former by investigating two approaches to improving the energy efficiency of aircraft. In the first approach, a novel methodology for aerodynamic shape optimization will be applied to the design of swept natural laminar flow wings for flight at transonic speeds. Implementation of such technology has the potential to reduce energy consumption by up to 10%. The second approach is a novel aircraft configuration, the hybrid wing-body configuration, which has the potential to improve energy efficiency by 10-25%, depending on the aircraft class. The hybrid wing-body configuration will be advanced through the application of a multi-fidelity multidisciplinary design optimization framework developed at the University of Toronto. Several issues identified during previous collaborative projects will be addressed, leading to a significant step toward commercialization of the hybrid wing-body configuration.
航空业面临着减少其对环境的影响,特别是对气候变化的影响的巨大挑战。为了实现这一目标,必须最大限度地提高飞机的能源效率,并迅速减少对化石燃料的依赖。多伦多大学和庞巴迪公司的合作主要集中在前者,研究两种提高飞机能源效率的方法。在第一种方法中,一种新的气动外形优化方法将被应用于跨音速飞行的后掠自然层流机翼的设计。这种技术的实施有可能将能源消耗降低10%。第二种方法是一种新的飞机布局,混合机翼-机身布局,它有可能提高10- 25%的能源效率,这取决于飞机的类别。将通过应用多伦多大学开发的多保真度多学科设计优化框架来推进翼身混合布局。在以前的合作项目中确定的几个问题将得到解决,从而朝着混合翼身组合体的商业化迈出重要的一步。
