The effects of ground on trimming and maneuvering control were studied.Taking a typical helicopter as an example,the trims for steady flight with different velocities and altitudes were first solved.Then control laws for lateral jink maneuver were obtained for helicopter NOE flight.The calculation results conform to the ground effect theory,and load factor and control variation of the maneuver can be used for reference.

The calcination of the catalysts at high temperature may easily result in theformation of tetrahedral structure Mo species before sulfidation,and decrease theamount of octahedral coordination Mo species.The sinter and loss of the activecomponents would take place during the calcination at overhigh temperature. Meanwhile,the active component could react with support,thus made the activecomponents entered into support bulk phase.
