Problems solved by technology

This kind of technical system has low energy efficiency, heavy weight, and low survival rate on the battlefield, which also affects the combat capability of aircraft; while high-end drones usually use electric energy systems, and reusable space-to-ground vehicles use combined power, which is difficult to adopt. The hydraulic control technology system, on the contrary, puts forward urgent application requirements for the "multi-electric" power transmission technology
