Control, Bomb release Type B-2A
Revision as of 15:54, 1 March 2012 by RadioNerds (talk | contribs)
The bomb release timer used on many US made WWII aircraft was used to time the release of bomb out of the aircraft. This allowed the pilots to accurately space the impact of the bombs based on airspeed. Generally the timing is adjustable from 0.08 second to 1 second between pulses.
There are three main controls
- Interval Between Bombs
- Controls the time between the pulses
- Bombs to be released
- controls the number of pulses 1-50
- Sel / Train
- not sure what this is for.
Function
The B-2A connects two pins together on every pulse. These pins can be used to complete a circuit to drive a relay or similar switched item
NOTE: It does not provide any voltage on the connected pins, only acts as a momentary switch.
