Abstract
Focused on the determination of power losses of grarbox, discussed a indirect measurement method of helicopter IGB,MGB,TGB transmission efifciency.The method based on main grarbox input power (the output power of the engine), tail rotor shaft output power can be measured, avoids thetechnical dififculties of direct measurement of transmission efifciency, according to the measurement of oil temperature, oil lfow note, shall surface temperature of radator pipeline and gearbox's working vironment temperature. Calculation model of power loss was established through the grarbox mathematical heat trasfer, get the power loss of IGB, MGB, TGB. The method dose an important exploration of helicopter grarbox transmission efifciency test measurement, lay the foundation for further transmission efifciency test lfight.关键词
