The Rockomax BACC Solid Fuel Booster is a large solid rocket booster.
Usage
BACCs are one-shot rocket boosters often used to help get the massive bulk of a large multi-stage rocket off the ground. They burn at a constant thrust until they run out of fuel and then cease to work. It should be noted that more boosters doesn't reduce the need for liquid fuel, as one must also take into account thrust to weight ratios. Thrust can be regulated with tweakables, minimum required for booster to lift it's own weight off Kerbin surface is 24%.
BACC Solid Fuel Boosters are prone to overheating, especially when large numbers are clustered together. The main ways to overcome this are by using custom staging to stagger the firing, and attaching additional parts that are not SRBs (typically struts, control surfaces or winglets) to act as heat sinks.
In バージョン 0.23, the BACC has an on-pad specific impulse (or Isp) of 230 s, slightly better than that of the RT-10 Solid Fuel Booster and comparable to the least efficient liquid fuel engines. Its thrust and mass ratio are good enough to make it a popular choice on first stages.
