doi:10.12060/j.issn.1000-7202.2014.02.08

Abstract

Abstract: Thrust is the key parameter in liquid rocket engine, so thrust measurement is very important during the research test.Thrust calibration is an important link of thrust measurement,loading system is the basis of force value transferring.The composing and the work principle are described, the key technologies of system development are proposed and the technical way of conquer points is analyzed.The system′s loading capability is 0t～100t, the stability attains 0.001% by experiments, and the efficiency and accuracy of thrust calibration are improved.

Key words: Rocket engine, Thrust, Auto-calibration, Loading system
