R22 throttle control

[Iridus]

Hi I'm a helicopter enthusiast and aspiring pilot. anyways I was wondering if the r22 and r44 have automatic throttle governers that adjust engine rpm or if the pilot must twist the throttle manually all the time.

[Revel99]

The R22 and the R44 both have governors that assist in maintaining engine RPM's

They both have governors that adjust RPM.

[Eric Hunt]

The governors control RRPM by adjusting (opening or closing) the throttle. They do not adjust the RPM, which is fixed at (I think) 103%.

 

But you should get your instructor to teach you to fly in manual throttle for when the fit hits the shan.

[Revel99]

The governor assists in maintaining engine RPM not rotor RPM. The low rotor horn will activate if you drop below 97% engine or 90% rotor, both conditions must exist. There is also a corelator linked to the collective that controls fuel , so as you pull pitch more fuel is added. So if you were to lose the governor yes you would have to control the throttle. The corelator will do much of the work but there is fine adjustments one would need to make to prevent low rotor or prevent an over speed.

 

After I posted this I actually woke up and was thinking while in the shower. The engine speed is not part of the low rotor horn. There is a magnetic sensor between the engine output and upper sheve, that measures the rotor RPM. Sorry for adding confusion.

Just to correct your numbers...the low rotor rpm warning light and horn have nothing to do with the engines rpm.

 

The warning is based on rotor rpm and is set at 97% of the rotors. I am not sure if you fly robbies but alot of us here do, myself included. We test this system every flight to make sure it works.

 

Where are you coming up with your 90% number and the part about the engine?

[Revel99]

Yes sir,

You are correct, I was thinking of operating ranges. Sorry for my speaking before completely think through the question.

[WolftalonID]

Hey no worries mate.

 

Just currious, seems your new to the forums. Where are out of? How long have you been flying helicopters, or interested in them? This place has a ton of information and lots of very educated pilots to meet and get to know.

 

Welcome to VR.

 

Plus we like to poke ribs from time to time...and occasionally gouge each others eyes when it gets heated up. Lots to learn in here...see my signature? Many guys here can attest to why I had to put that there. Lol

 

Looking forward to seeing more from you on the forum, feel free to ask away in here but stand back when the fun flies!

Actually, per the Robinson Maintenance Manual....

 

it is set at a range of 96 to 97 %

Also, the Rotor RPM is measured at the flex coupling near the Main Rotor Gearbox. If you feel the back side the the GB side yoke flange, you'll feel magnets between the drive shaft and the bolts that hold the yoke flange to the flex plate.

I have completed my PPL and currently working on my Instrument rating. I am in Phoenix, AZ. Flying has been a life long dream and I am doing my best to live that dream. My goal is to earn a Commercial/ CFII rating.

 

No worries, I always attempt to be respectful from the start, till it is time to not be. Thank you causing me to think about what I said and learn from my mistake.

[WolftalonID]

Well congrats to working on your dream! Its worth the efforts..keep it up. I have met a few pilots that have come from the Phoenix area. Seems to be a great place to fly.

[Revel99]

Nice calm smooth weather most the year, a little convective action going on during monsoon season. Night flight are great as well.

I did my training up in Prescott, AZ. I always enjoyed flying Phoenix at night.

 

What school are you training with?
