crashed_05 Posted September 16, 2009 Posted September 16, 2009 I thought this was a pretty cool video demonstrating autorotations in the R-22. There's a part two also. I've not yet had experience doing these so let me know what y'all think...things that were done right, things that could have been better. Quote
kodoz Posted September 17, 2009 Posted September 17, 2009 Helicopter Concepts has a decent video that I've been passing around to VIP members [link], and you can see a lesson plan for autos here [link]. Quote
JDHelicopterPilot Posted September 17, 2009 Posted September 17, 2009 I have that DVD from Helicopter Concepts. Not bad at all. I think it was worth it to get the video. JD Quote
Goldy Posted September 17, 2009 Posted September 17, 2009 (edited) I have that DVD from Helicopter Concepts. Not bad at all. I think it was worth it to get the video. JD JD- Remember it's 65 knots, NOT 165 knots !!! (best you keep watching that CD, you get old, you start flying the fastest ship in the air...and you forget these things!) I think its pretty gutsy of a CFI who is letting a 15 hour rotary pilot doing autos in an R22 to be using one hand to video tape his death...I mean, the autorotation. Lots of things that can go wrong in those last few seconds....I'll keep both my hands on the controls thank you. Goldy Edited September 17, 2009 by Goldy Quote
JDHelicopterPilot Posted September 18, 2009 Posted September 18, 2009 So true Goldy. I'll be reminded of that fact next month on my recurrent 135 ride. Last time I had the pleasure of doing any autos was a year ago. At least I am able to sneak in other stuff when I can. I wish we had additional flight training during the year but no go thus far.

Mungo5 Posted September 18, 2009 Posted September 18, 2009 One question, when he says "Pitch Pull" i presume he means add a little pitch to the rotors by raising collective? Having not flown an R22, I assumed you'd want the collective on the floor given the low inertia of the rotor system? 300's are down, right, aft, then raise collective a teensy weensy bit prior to the flare to stop overspeed in the flare.

On a side note, their attitude indicator apeared to be less than reliable. Quote
Mrotorcraft Posted September 18, 2009 Posted September 18, 2009 "That's the attitude indicator (AI), which unless we are doing instrument instruction we usually leave them turned off. Many more videos similar to this are soon to come." - michaelmiller85 Not sure why... Quote

Inferno Posted September 19, 2009 Posted September 19, 2009 It all depends on weight and the air density/temp. Having never done an auto solo in a 22, i can not say this for a fact, but you would leave it all the way down, and even then the rotor rpm would not be up in the green. With 2 pilots and a nice helping of gas onboard, on a hot day (40C), you have to raise the collective quite a bit after the initial entry to keep the rotor rpm from shooting up quickly.... And when i say quickly, i mean like a fing rocket...One question, when he says "Pitch Pull" i presume he means add a little pitch to the rotors by raising collective? Having not flown an R22, I assumed you'd want the collective on the floor given the low inertia of the rotor system? 300's are down, right, aft, then raise collective a teensy weensy bit prior to the flare to stop overspeed in the flare.

The way you describe your auto in the 300 is just like the R-22. However, as with any helicopter you maintain rotor RPM by collective. RPM and collective setting in your auto may vary with conditions. It may not be set all the way to the "Floor" as you say except perhaps in entry to recover some of your RPMM. You are right it is a low inertia system. That is to say your RPM will drop quickly. You are forgeting though you recover RPM quickly as well. As a result "check collective" or "Pitch Pull" terms are sometimes said by CFIs to remind students to check RPM or to raise collective slightly to maintain RPM. No two autos are the same. JD Quote
mechanic Posted September 19, 2009 Posted September 19, 2009 He seems to come across to be a pretty good CFI. I think I would like flying with him. Quote
