摘要： By removing the aerodynamic fin forces from the fin lock mechanism (12), achieved by actuating the fin control system to apply a controlled force that counters the aerodynamic forces acting on the control fins (20), the system can reduce the transmission of aerodynamic forces onto the fin lock mechanism (12), which makes the fin lock mechanism (12) easier to unlock with less force. Accordingly, a method for unlocking a fin lock mechanism that releasably holds one or more missile control fins in a locked position, where the control fins are prevented from rotating, includes the steps of (i) applying an alternating positive and negative rotational force to a control fin; (ii) monitoring the position of the control fin during the applying step; and (iii) while the position of the control fin does not exceed a predetermined value, repeating the applying step for a predetermined number of times or for a predetermined period.
