If the power plant is too far below the rotor disc , there will be a discernable pendulum effect 如果電廠是過分低于轉(zhuǎn)子盤,將有可辨的鐘擺效應(yīng)
If the power plant is too far below the rotor disc , there will be a discernable pendulum effect 如果太電廠,遠遠低于轉(zhuǎn)子盤,將有跡可尋鐘擺效應(yīng)
By keeping this center of mass closer to the rotor disc the pendulum effect is reduced and the helicopter is markedly more stable 保持這種質(zhì)心接近轉(zhuǎn)子盤鐘擺效應(yīng)明顯降低,直升機更穩(wěn)定
By keeping this center of mass closer to the rotor disc the pendulum effect is reduced and the helicopter is markedly more stable 靠著這種質(zhì)心接近轉(zhuǎn)子盤鐘擺效應(yīng),減少了直升機著較為穩(wěn)定
This short - arc coupled with the low pendulum effect achieved by pivoting the disc through a point near its center of gravity assures rapid closure 繞軸旋轉(zhuǎn)的閥瓣的重力中心距軸心較短,因此這種短弧的鐘擺效應(yīng)也比較小,從而確保能夠迅速關(guān)閉。
