Aiming at the struts
the key components for the installation and support of helicopter main reducers
the research progress of conventional struts and intelligent struts is analyzed in combination with the development trend of strut structures. [Analyses] The mounting and support layouts of helicopter main reducers are divided into flange type
strut type and other structural forms. The structural characteristics and application scope of each layout are summarized and analyzed. Combined with typical aircraft cases
the application status of different mounting and support layouts in conventional single-rotor and coaxial twin-rotor helicopters is concluded. [Outlooks] The collaborative optimization of lightweight materials and intelligent algorithms is proposed as the key approach to improve the dynamic performance of the support system in the future.
