Bombardier recently certified its CSeries and the Global 7000, which represent its first Fly-By-Wire (FBW)**commercial aircraft and business jet, respectively. These two aircraft are equipped with the first generation of**Bombardier FBW automated flight control laws. As part of its research and development activities, the**company is exploring technologies that could be required for future generation of such flight control laws.**Specifically, technologies to estimate on-board and in real-time the aircraft mass and position of centre of**gravity have been identified as important parameters. Indeed, such capabilities will allow scheduling the gains**of the flight control laws during the flight as a function of these parameters instead of designing them as**constants before the flight. This will significantly improve the performance of the flight control laws. In this**context, Bombardier has already developed two types of mass and CG position real-time estimation algorithms.**The first is operational in steady-state flight conditions, whereas the second operates when the aircraft**dynamics is excited (transient). While these solutions seem to have promise, there is a need for deeper**theoretical and practical investigations by state estimation specialists. In this context, the main objective of this**research project is to further develop and analyse the two solutions to enhance their technology readiness level;**thereby making the resulting innovation mature and closer to be implemented on Bombardier's FBW aircraft**for flight testing.

庞巴迪最近认证了其C系列和Global 7000，这两款飞机分别代表其首款电传操纵（FBW）** 商用飞机和公务机。这两架飞机配备了第一代 ** 庞巴迪FBW自动飞行控制律。作为其研究和开发活动的一部分，** 公司正在探索未来一代此类飞行控制律可能需要的技术。具体而言，机载和实时估计飞机质量和重心位置的技术已被确定为重要参数。实际上，这种能力将允许在飞行期间将飞行控制律的增益 ** 安排为这些参数的函数，而不是在飞行之前将它们设计为 ** 常数。这将大大提高飞行控制律的性能。在此背景下，庞巴迪已经开发了两种类型的质量和重心位置实时估计算法。第一种是在稳态飞行条件下工作的，而第二种是在飞机 ** 动力学被激励（瞬态）时工作的。虽然这些解决方案似乎有希望，但需要状态估计专家进行更深入的理论和实践调查。在此背景下，该研究项目的主要目标是进一步开发和分析这两种解决方案，以提高其技术准备水平;** 从而使由此产生的创新成熟，并更接近于在庞巴迪的FBW飞机上实施 ** 进行飞行测试。
