1.一种适于从飞机上投放并武装在自由落体飞行中的炸弹的引信中，壳体，安装在所述壳体中的用于从初始安全位置到武装位置以增量距离移动的武装转子可旋转，连接到所述转子的延时机构，用于防止所述转子在预定时间间隔内移动，所述延时机构包括储能弹簧装置，用于在所述时间间隔之前移动所述转子通过第一增量距离，并且用于在所述时间间隔期满时移动所述转子通过第二增量距离，与所述转子连接的转子锁定装置，用于当炸弹受到预定的最小空气速度时，通过所述储能装置释放所述转子以通过所述第一增量距离移动，并用于启动所述延时机构；以及环境动力驱动装置，安装在所述壳体上，并且定位为当所述转子已经移动通过所述第二增量距离时驱动与所述转子接合，以将所述转子驱动到所述武装位置，从而在所述飞机以正常发射空气速度释放炸弹之后的预定时间间隔期满后武装所述炸弹。
1. In a fuze for a bomb adapted to be dropped from an aircraft and armed in free fall flight, A CASING, AN ARMING ROTOR ROTATABLY MOUNTED IN SAId casing for movement from an initial safe position to an armed position in incremental distances, A TIME DELAY MECHANISM CONNECTED TO THE ROTOR FOR PREVENTING MOVEMENT OF THE ROTOR FOR A PREDETERMINED TIME INTERVAL, SAID TIME DELAY MECHANISM INCLUDING A STORED ENERGY SPRING MEANS FOR MOVING THE ROTOR THROUGH A FIRST INCREMENTAL DISTANCE PRIOR TO SAID TIME INTERVAL AND FOR MOVING THE ROTOR THROUGH A SECOND INCREMENTAL DISTANCE AT THE EXPIRATION OF SAID TIME INTERVAL, A ROTOR LOCKING MEANS CONNECTED TO SAID ROTOR FOR RELEASING SAID ROTOR FOR MOVEMENT THROUGH SAID FIRST INCREMENTAL DISTANCE BY SAID STORED ENERGY MEANS WHEN THE BOMB IS SUBJECTED TO A PREDETERMINED MINIMUM AIR VELOCITY AND FOR STARTING SAID TIME DELAY MECHANISM, AND AN ENVIRONMENTALLY POWERED DRIVING MEANS MOUNTED UPON SAID CASING AND POSITIONED FOR DRIVING ENGAGEMENT WITH THE ROTOR WHEN THE ROTOR HAS BEEN MOVED THROUGH SAID SECOND INCREMENTAL DISTANCE FOR DRIVING THE ROTOR TO SAID ARMED POSITION, WHEREBY SAID BOMB IS ARMED AFTER THE EXPIRATION OF A PREDETERMINED TIME INTERVAL SUBSEQUENT TO RELEASE OF THE BOMB BY THE AIRCRAFT AT NORMAL LAUNCHING AIR SPEEDS.
