The technical roadmap of the development of variable pitch propeller governors for turboprop
摘要
Abstract
The variable pitch governor controls the propeller to maintain a constant speed,so that the propeller can be energy-saving and efficient in a wider range of flight envelope.Many foreign countries have developed variable pitch governor with electro-hydraulic servo through a number of advanced turboprop aircraft,while China has a few self-developed variable pitch governor products,many of which are mechanical-hydraulic type.The mechanism and background of the governor and reviews of its current research status at home and abroad are analyzed.The key technical problems such as insufficient lightweight reliability strategy,internal electro-hydraulic servo valve oil sen-sitivity,and difficulty in the integration of the propulsion system electronic control unit are analyzed for the electro-hydraulic servo type governor.Based on that,the trends of electrification,digitalization,and intelligentization in the technology of variable-pitch governor for turboprop aircraft are prospected.The corresponding solution ideas are provided to give reference for the further research of the advanced governor in China.关键词
