Abstract:In response to the issues of model-specific, incompatible, and high development costs of ground equipment for propellant level measurement caused by the multi-model development of China’s new generation launch vehicles, this study conducts unified design research. A comprehensive analysis of the common functional and personalized interface requirements for propellant level measurement across various new generation launch vehicles is performed. A top-level architecture is planned. The propellant level sensors, transducers, and ground processing equipment for different launch vehicles are systematically reviewed. A generalized design for the hardware, software, and interfaces of the ground processing equipment is implemented, enabling a single hardware platform to support multiple launch vehicle models. Simulations and tests demonstrate that the unified equipment meets the mission requirements of all target models in key indicators such as measurement accuracy, reliability, and the localization rate of components. Validation through actual launch site propellant loading tests confirms that the equipment meets operational requirements, significantly improving the universality and support efficiency of ground equipment, which is of great importance for adapting to high-density launch missions.
