Abstract

The article gives an overview of methods for determining the attitude angles from observations of external reference vectors. To maintain the observability of the kinematic parameters of a free-flying airplane model motion in a vertical wind tunnel, we analyze the methods for determining the finite rotation vector using two, three or more vectors known in the model body frame, as well as their derivatives. The methods to estimate the reliability of the calculated attitude angles are proposed. The method for estimating the radius of the free-flying model steady-state spin is considered.

飞机自由旋转研究中矢量观测的姿态角确定

摘要

本文概述了根据外部参考矢量的观察确定姿态角的方法。为了保持可自由飞行的飞机模型运动在垂直风洞中的运动学参数的可观察性，我们分析了使用模型主体框架中已知的两个，三个或更多向量确定有限旋转向量的方法，以及衍生品。提出了估计姿态角可靠性的方法。考虑了估计自由飞行模型稳态自旋半径的方法。
