The demand for multi-environmental modes of transportation is driven by the overall trend of increasing mobility and the necessity of movement across various alternating environments (land, water, underwater, aerial, and airspace). However, the specific energy density of hydrocarbon fuels cannot ensure efficient operation of power systems for such multi-environmental vehicles. A promising solution to this problem involves the utilization of boron-containing metallized fuels through the creation of specialized fuel supply systems. Based on a general method of optimization synthesis for technical objects, new fuel supply systems were synthesized with different levels of process control and degrees of automation, as well as an adjustable hybrid fuel delivery system that allows the application of components in varying aggregate states. During testing, operational characteristics were determined primarily for the implemented metallic hybrid transformer fuel delivery system. In our view, it holds the greatest potential for the utilization of metallized fuels, as it provides an expanded range of applications, increased functions, and structures. This is also linked to the possibility of employing boron in the α-modification, where atomic-level processes ensure maximum combustion efficiency. Thus, the new fuel supply system offers functionality across diverse environments, creating genuine prerequisites for the efficient operation of power systems for multi-environmental modes of transportation.
