WebSemi-rigid (teetering) Rotors. Semi-rigid rotors are found on aircraft with two rotor blades, such as Robinson, Hiller, and many Bell products. The blades are connected such that as one blade flaps up, the opposite blade will flap down. Allowing the rotor system to ‘teeter’ at the top of the rotor mast accommodates this. Intermeshing rotors on a helicopter are a set of two rotors turning in opposite directions with each rotor mast mounted on the helicopter with a slight angle to the other so that the blades intermesh without colliding. This configuration is sometimes referred to as a synchropter. Meer weergeven On a helicopter, the main rotor or rotor system is the combination of several rotary wings (rotor blades) with a control system, that generates the aerodynamic lift force that supports the weight of the helicopter, and the Meer weergeven Most helicopters have a single main rotor but require a separate rotor to overcome torque. This is accomplished through a variable-pitch antitorque rotor or tail rotor. This is the … Meer weergeven Helicopters with teetering rotors—for example the two-blade system on the Bell, Robinson and others—must not be subjected to a low-g condition because such rotor … Meer weergeven • Rotor Analysis - Blade Element Momentum Theory • Helicopter Rotorhead Close-up Image Gallery • "Helicopter Aircraft".
