Chapter 247

Feng Xiaoqing explained, "The principle behind this is actually similar to that of a recoilless rifle. In early recoilless rifle designs, engineers attached a counterweight block to the rear of the breech. When fired, this block would fly backward to balance the recoil. We can replace this counterweight block with a piston and fill the space behind the piston with water. In this way, the original rear-spraying fire is replaced by rear-spraying water, thereby achieving the effect of eliminating recoil." Guan Hui suggested, "Through this method, we can effectively solve the recoil problem. However, the range issue remains, because spraying water backward also consumes energy." Feng Xiaoqing replied, "We have a way to deal with this as well. The piston is designed with a dual caliber: the smaller caliber at the front matches the gun barrel, while the rear features a larger caliber piston. The piston's stroke is thus greatly reduced, thereby lowering energy consumption."
