Kenny Keller’s Day #14 short helicopter ground-school video explains the three types of helicopter rotor systems (fully articulated, semi-rigid, and rigid). He defines key characteristics of each: fully articulated blades can lead/lag, flap, and feather independently; semi-rigid blades flap and feather as a unit (no lead/lag) with examples like the R22 and JetRanger; rigid systems allow feathering. He emphasizes knowing which system your aircraft uses.

Welcome to day 14 of the helicopter 3s and today I wanted to hit the three types of rotor systems. Common question on about any checkride examiner is probably going to ask you what are the three types of rotor systems you have? The fully articulated, the semi rigid and the rigid. And he's going to want you to understand some of the simple things or not simple things. He's going to want you to understand some of the things about these. The differences in the rotor systems. The fully articulated example is the instrument and the blades on a fully articulated can lead and lag, flap and feather independently. Then on a semi rigid for example R22 Jet Ranger, the blades can flap and the blades can feather. They do not lead and lag. They flap as a unit. They flap and feather. And then the rigid system, the rigid system can do is feather. So know those three rotor systems, know the differences between the three, know which one that you have on the aircraft that you're particularly flying. That's pretty important. So as always, thanks for stopping by and please click the like button and we will see you tomorrow on day 15.
