In flight, they also change their pitch angle to generate the helicopter’s direction of flight, speed and lift. I guess a good place to start is to ask the question, “Why do rotor blades need to be tracked and balanced?” Rotor blades travel around a hub at a given speed. Tail rotors also need to be tracked and balanced, but we are not going to address that in this article. This is probably not too far from the truth, but the whole concept of rotating parts is where the tracking and balancing of the main rotor blades comes into being.
Many perceive a helicopter as a conglomeration of rotating parts that, in order to fly, work in unison to beat the air into submission. A helicopter’s flight dynamics are so different from a fixed-wing aircraft’s that we encounter maintenance issues that are totally unique to helicopters. Helicopters, on the other hand, are inherently unstable, and if you put one in straight and level flight and take your hands off the controls, it will undoubtedly try to roll over on its back. That is, if you place the aircraft in straight and level flight and take your hands off of the controls, the aircraft will pretty much stay where it is. Most fixed-wing aircraft are inherently stable. No answers are wrong - they just differ from each other. It is a vibration analysis and balancing tool that quickly and accurately acquires and analyzes.Īsking seven helicopter maintenance professionals for their insight on rotor blade track and balance is like asking seven sportscasters which is the best college football team you will get seven different answers.
