Presumable range of initial disturbances of ship-launched rocket with ship swaying considered;

The relation between some rocket launcher support stiffness and the initial disturbances of the rocket was studied by the method of combining the multi-rigidbody dynamics simulation with the experiment implemented by designing launcher with adjustable support stiffness and using optical lever measurement.

,Processing mass unbalance and dynamic unbalance as random excitation,it s influence on initial disturbances of rocket has been analyzed.

Mass eccentricity,thrust eccentricity and windage are main factors affecting impact action and initial disturbance parameter values of rocket projectile in the direction pipe.

After all, the initial disturbance is diminished and firing concentration of MLRS is improved.

A corresponding computer program can be used to perform the analytical computation of the vibration of the infrared light axis during the launching process, the initial disturbance of the missile, and the random distribution of the missile during the uncontrolled flight .

Trajectory numerical simulation of super high-speed underwater vehicle owned initial perturbation;

Initial perturbations scheme is one of the important problems in the ensemble prediction.

The simulation results with the environmental stability starting convection show that the initial perturbation is one of the key elements that influence the development of the cumulus.

Effect to the Parameters of Anti-Aircraft Missile Trajectory by the Interference of Initial Launching;
