Research on Cooling Test Technology of Civil Helicopter Power Plant and Lubricating Oil System
摘要
In view of the airworthiness review requirements of civil aviation regulations on the cooling capacity assessment of civil helicopters, the cooling test technology of civil helicopter power plant and lubricating oil system is studied. The test data under the planned flight subjects are obtained by adding temperature sensors and signals on the helicopter. The measured temperature data is corrected to the temperature correction data under the upper limit of the helicopter's operating temperature according to the formula, and then the temperature correction data is compared with the temperature limit of relevant accessories and materials to obtain the cooling capacity assessment results. The cooling test technology of civil helicopter power plant and lubricating oil system is studied, which provides a reference for the cooling test of various types of helicopters.
