I knew that there was an arming unit on the front of the bomb carrier, but in my ignorance I thought it was a one time, one-way operation. Re. the arming solenoid, just so I have that correct, would I be right to assume that the arming unit had a default of allowing the bombs to drop safe, i.e. the arming wire was free to drop with the bomb unless the solenoid was energised by the arming switch to trap the wire to the carrier as you described? Cheers, Dave No, it's just the opposite Dave, you need power to enable a 'safe' drop (of course, thinking about it, you need power for 'any' drop don't you). Perhaps they figured it'd be better to have it 'fail safe' to 'armed' just in case there was a fault in the arming circuit which would preclude an armed drop, There's logic to that, even if it is a bit counter instinctive to the modern way of thinking. In other words maybe they thought this 'safe drop' wasn't a real important feature and didn't want to endanger the mission for it's slight added advantage, If you had to jettison them because of an impending forced landing then you could jettison live over the ocean or the countryside. I just loved that old story about the RAF bomber that returned to base after a leaflet raid in 1940. They reported to the IO that they had been attacked by a fighter and had had to jettison the bales intact rather than first cutting the wrapping wires. 'Good God,' said the IO, 'you could have killed someone!' Perhaps Art could give us some pointers?. -- -Gord. Cheers, Dave -- Dave Eadsforth |
