directional moment of inertia
1Directional stability — is stability of a moving body or vehicle about an axis which is perpendicular to its direction of motion. Stability of a vehicle concerns itself with the tendency of a vehicle to return to its original direction in relation to the oncoming medium …
2inertia coupling — A form of instability that manifests itself during maneuvers, especially in the pitching and yawing motions. It is particularly common during rolling at very rapid rates and high g rolling pullouts either at very low indicated air speeds or at… …
3Flight dynamics — is the science of air and space vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle s center of mass, known as pitch , roll and yaw… …
4Stability derivatives — are a means of linearising the equations of motion of an atmospheric flight vehicle so that conventional control engineering methods may be applied to assess their stability.The dynamics of atmospheric flight vehicles is potentially very… …

8Hunting oscillation — The classical Hunting oscillation is a swaying motion of a railway vehicle caused by the coning action on which the directional stability of an adhesion railway depends.Below a certain critical speed, the motion is damped out, above this speed… …
