For general applications in 3D, often need to perform 3 separate rotations to relate our inertial frame to our body frame Especially true for aircraft problems There are many ways to do this set of rotations -with the variations be based on the order of the rotations All would be acceptable

Static stability is all about the initial tendency of a body to return to its equilibrium state after being disturbed To have a statically stable equilibrium point, the vehicle must develop a restoring force/ moment to bring it back to the eq. condition Later on we will also deal with dynamic stability, which is concerned with the time history of the motion after the disturbance

Aircraft Lateral Dynamics Using a procedure similar to the longitudinal case, we can develop the equa tions of motion for the lateral dynamics

7.1概述 功用:保证发动机正常工作的所需的“神经”系统组成:主要有滑油、起动、燃油与调节系统,以及保证它们正常运行的传动系统。有的机种还有喷水、冷却系统等。(为防内容重复,本章主要介绍滑油、传动系统) 7.2滑油系统
