The BRU-61/A bomb rack, used on military aircraft, allows for the carriage and release of multiple munitions. The pitch valves on a BRU-61/A bomb rack control the pitch or vertical orientation of the munitions.
These valves are typically set according to specific mission requirements and aircraft configurations. The exact procedure for setting pitch valves may vary depending on the aircraft and munitions being used.
Typically, ground crew or maintenance personnel will adjust the pitch valves based on guidelines provided in the aircraft's technical manuals. Properly setting the pitch valves ensures that the munitions are released at the desired angle and trajectory during a mission, optimizing their effectiveness.
