Abstract:The multi-component thrust measurement test is a direct means of obtaining flight thrust data for aeroengines. This
technology has become one of the indispensable key technologies in the field of aeroengine testing. After years of development, many
breakthroughs have been made in the structural form of multi-component box balance used for thrust measurement. Targeting the testing
requirements for aeroengine thrust measurement in the context of aviation engineering, the technical applications of multi-component box
balance are sorted out, the structural composition, size, and material selection of single-component box balances, three-component box bal?
ances, and six-component box balances are summarized. The number and layout of elastic connecting rods in different types of box bal?
ances are analyzed. The transmission paths of thrust during aeroengine tests are studied. In-depth comparisons of the performance
parameters of different types of box balances are conducted. On this basis, the key technologies for developing multi-component box bal?
ance are elaborated, including reducing the influence of mechanical coupling, realizing the precise measurement of low thrust, developing
environmentally friendly thrust calibration systems, and carrying out multi-disciplinary joint simulation, providing new ideas for box bal?
ance design. |
