Also the teetering rotor
head that holds the rotorblades to the rotor head while allowing them to pivot and twist as required.
While a static All-1 simulator attracted most attention on the Bell stand with a view to extolling the virtues of the type compared with its teetering rotor
forebears, a large model of what could appear as a "sports" version of the Osprey revealed upon close examination that apart from the fact that it is intended to largely offer the same modus operandi, it technically was going to do it differently.
During this process, the two helicopters' existing two-bladed, semi-rigid, teetering rotor
system will be replaced with an advanced, four-bladed, hingeless, bearingless rotor system.
Advanced horizontal-axis turbines are likely to appear in three basic configurations: (1) a conventional upwind three-bladed rotor with rigid hub, active yaw, and active pitch (Danish design); (2) a downwind, two-bladed, teetering rotor
, with free yaw and fixed pitch; and (3) an up-wind, two-bladed, teetering rotor
with active yaw.
