In modern space engineering, it is necessary to provide minimal fuel and energy con-
sumption while providing high level of reliability for launching a payload to the required
orbit. Development of a precise and linear level gauge of the fuel consumption control
system can solve a part of the problem. Both the continuous monitoring and guiding the
fuel component consumption make it possible to synchronize tanks discharging more pre-
cisely and loss-free. It also allows getting rid of the fuel safety stocks in the tanks in case
of their full discharge, with the same fuel components launch mass being maintained.
Thus, it gives a boost to the carrier-rocket. In this case, a particular physical approach
is applied to solving the technical problem, which consists of using both physical proper-
ties of optical fiber and the impact of cable local deformations on the backscatter phe-
nomenon. A new level gauge is introduced for LRE fuel consumption management sys-
tem, which is based on the distributed control fluid sensor located in rocket fuel tank. The
concept of this fuel consumption management system is described. It allows for an in-
crease in LRE power characteristics. We examined some existing linear tracking systems
as well as fuel consumption synchronization systems of liquid carrier-rockets. We justi-
fied the choice of optical fiber cable for a level gauge and provided a level gauge hard-
ware flowchart. Furthermore, we carried out the comparative analysis of the described
physical method with a hypothetical analogue of a level gauge for LRE fuel consumption
control system.
