水平尾槳
英文
horizontal rotor-
< uk > the configuration has two tractor propellers, full - span double slotted flaps deflected 45, and a high tail. < / uk >
< uk >實驗模型有二兩拉力螺旋槳,全翼展雙縫襟翼偏轉45 ,並有高置的水平尾翼。 < / uk >The configuration has two tractor propellers, full-span double slotted flaps deflected 45°, and a high tail.
實驗模型有二兩拉力螺旋槳,全翼展雙縫襟翼偏轉45,並有高置的水平尾翼。The submarine noise detected by sonar consists of two parts : propeller - generated hydro - dynamical noise, which can be greatly reduced by improving the submarine rear shape ; radiated noise from the submarine structure excited by the centrifugal forces ( moments ) of rotatory machine, which is more complicated and influenced by many factors
聲納所探測的潛艇噪聲包括兩部分,一是螺旋槳運轉帶來的水動力噪聲,二是潛艇主機工作時產生的不平衡力和力矩引起潛艇結構振動,帶動流場振動從而輻射噪聲。通過改進潛艇尾部線型設計,已將水動力噪聲降到比較低的程度,而結構噪聲則復雜得多,與許多因素有關。For a conventional helicopter, the tail rotor is one of primary sources for helicopter noise
尾槳是直升機的主要噪聲源,降低尾槳噪聲對控制直升機的噪聲水平具有重要意義。分享友人
