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 thrust that counteracts aerodynamic drag in forward flight.

We offer sizes for any homebuilt rotorcraft application—both for the main and tail rotor of helicopters (the NACA 0012 and 23012 series), or for the main rotor of gyroplanes (the NACA 8H12 blades).

Rotor blade design covering aerodynamic aspects of airfoils, blade twist and tapper, blade root cut out, blade tip speed and noise reduction, and blade construction.

Learn how helicopter main rotor blades work, providing lift and control. Gain a clear understanding of their mechanics and functionality in this guide.

2017年3月18日 · The rotor blades used by the early Sikorsky and Piasecki helicopters were derived from those that had been developed for autogiros. Figure 1 shows the construction of these rotor blades. The main structural member was the steel tube spar to which ribs were attached using metal collars.

A fully articulated rotor is found on aircraft with more than two blades and allows movement of each individual blade in three directions. In this design, each blade can rotate about the pitch axis to change lift; each blade can move back and forth in plane, lead and lag; and flap up and down through a hinge independent of the other blades.

Experimental and Ultralight Helicopter Rotor Blades: available styles and sizes + base prices: The airfoil profile for the experimental/ultralight helicopter rotorblades is NACA23012 (see below drawing). The 23012 develops high lift and relatively low …

Each rotor typically has two or three blades. Coaxial rotor systems, seen in helicopters like the Kamov Ka-52, offer improved lift efficiency and maneuverability. Side-by-Side Rotor: This configuration features two main rotors mounted side by side on the same axis, with each rotor turning in opposite directions to cancel out torque.

Helicopter rotor blades are a vital component of the aircraft, responsible for generating lift and controlling the movement of the helicopter. Attached to the rotor hub, these blades rotate around a central mast, producing the necessary lift to maintain the helicopter’s airborne state.

2019年3月1日 · A wide variety of carbon-composite and aluminum rotorblades for homebuilt and experimental helicopters and gyroplanes, including direct replacements for RotorWays, Mosquitos, Mini-500s, RAF-2000, Bensen, Air Command, etc.
