In this article, we present the development and treatment of an inverse problem applied to data from the Felix Baumgartner stratospheric jump. This jump is well documented with a lot of data. Therefore, it makes a particularly well-suited example for teaching in a numerical techniques laboratory. The major aim of the article is to give guidelines in order to construct a simple, but not simplistic, inverse problem with real data for junior undergraduate students. Students should master classical mechanics and have some skills in numerical modelling. We use the programming language Python and various libraries in order to build a model and solve the entire problem. This programming language is increasingly used and understood by students, which allows them to focus on the physical and numerical aspects of the involved problem. The fairly new strategy presented in this article is an attempt to estimate the angle of attack from acceleration measurements, and to give an uncertainty e...

本科数值技术实验室的高空自由落体和参数估计

在本文中,我们介绍了反问题的发展和处理,该反问题适用于Felix Baumgartner平流层跃变的数据。大量数据充分证明了这一跳跃。因此,它为在数字技术实验室中的教学提供了一个非常合适的示例。本文的主要目的是提供指导,以便为初中本科生构建一个具有实际数据的简单而不是简单化的逆问题。学生应掌握古典力学,并具有一些数字建模技能。我们使用编程语言Python和各种库来构建模型并解决整个问题。学生越来越多地使用和理解这种编程语言,这使他们能够专注于所涉及问题的物理和数字方面。
