尾部共震-美國官方的回覆
Tail Resonance.
Upon spool up, the helicopters will experience a vibration in the tail assembly, but only during spool up. The tail is hitting a resonant frequency at a certain head speed; this is not a problem, it’s just something the 130 X does. The key is to quickly move through this head speed range. To avoid this issue, advance the throttle from low throttle to about 75% throttle immediately. The goal is to pop the helicopter off the ground as quickly as possible without letting it stay at the head speed that causes the resonant vibration. Once it moves past this head speed and is off the ground and in the air, the vibration will disappear.
Tail resonance can also occur when holding the helicopter and spooling it up. Helicopters are not designed to be held static when the rotors are turning, and Horizon does not support or recommend doing this!
原文翻譯:
尾部共震.
在起飛時, 直昇機尾部會有些微震動,但僅在起飛時。尾巴在某個轉速點會有共震出現,這是正常的130 X會有的反應。重點是要快速的通過這個轉速範圍,來避免這個問題,從低油門快速的升到75%油門。主要是要讓直昇機快速的離開地面,不要讓它停留在會有共震的轉速。一旦通過那個轉速並起飛,就不會產生震動了。
尾部共震會發生在停旋和起飛。在主旋翼旋轉的時,直昇機停旋時也不會讓直昇機靜止不動。 Horizon也不建議這麼做!
