Abstract
The invention belongs to the technical field of engine detection, and particularly relates to a liquid rocket engine mass center dynamic measurement system based on ultrasonic waves. Comprising a first ultrasonic transducer array, a second ultrasonic transducer array, a signal processing module and a calculation unit, the arrangement position of the first ultrasonic transducer array corresponds to the position of a liquid fuel storage tank, and the arrangement position of the second ultrasonic transducer array corresponds to the position of a liquid oxidant storage tank; each of the first ultrasonic transducer array and the second ultrasonic transducer array comprises a plurality of ultrasonic transducers arranged in the same vertical plane; the calculation unit is used for calculating the coordinate of each liquid level echo point according to each reflection echo received by each ultrasonic transducer array; and the center-of-mass calculation module is also used for calculating the center-of-mass coordinate of the liquid rocket engine according to the liquid level echo point coordinates corresponding to the first ultrasonic transducer array and the second ultrasonic transducer array. According to the invention, real-time monitoring of the mass center position of the liquid rocket engine can be realized.
