I like the whispering and birds chirping in the background, its like a ASMR video. I'm not sure what a constant speed propeller is but, I fell asleep half way through.
YOU ARE THE BOSS....I was reading the Jeppesen Aicraft Systems Book for Pilots and I couldn't understand anything, you have illuminated me...thank you so very much for this video
On speed Condition = oil in lock position because the pressure on Speeder Spring and centrifugal force is balanced OverSpeed Condition= As RPM increase, Centrifugal force increase (fly weight move outward + Pilot valve move upward) directing pressured oil from booster pump to piston to Increase blade angle ( coarse pitch), RPM decrease, then on speed Condition UnderSpeed Condition= As Spring pressure is stronger than Centrifugal force, (Fly weight move inward + Pilot valve move downward) directing oil from piston to be routed back to the engine. Blade angle decrease (fine pitch), Engine RPM start increase, the On Speed condition +Pilot adjust the amount of pressure on the speeder spring to change the Pitch of the blade +Booster pump supply pressurized oil (180psi - 300psi) +The shuttle type valve used on pilot valve (alternately cover and uncover oil passage allowing oil to flow in/out of propeller hub
great explanation, i love that you keep it simple, anything well understood should be able to be explained simply. This is how it works on some planes however, I noticed on the diagram it says "feather" Most airplanes that go into feather (multi) do so with a lack of oil pressure, in case oil pressure is lost it can go into feather. Basically the diagram that you drew, but the lines to / from the oil sump and oil pressure would be reversed. Also, the driving forces trying to drive the prop to feather would be: a counterweight, nitrogen and a spring in prop hub. For new pilots think of it only for the way it works on the airplane your flying, don't confuse yourself.
Steven McEvoyI wanted to clarify my above statement, its not just so much as the lines are reversed. On the other system, the High pressure oil is now trying to drive the prop to fine pitch, but it is pushing against nitrogen and a spring, and not oil.
Steven McEvoy You're correct Steven and thanks for the comments. If I'm not confusing the matter, this type of propeller could go to the feather position with the aide of a "feathering pump". I'll probably do a video on that topic at some stage.
This is the best video on TH-cam to explain this. Great job! You used lots of terms other videos didn’t use. Your voice was just fine these people just have a stick stuck in the wrong place.
Great explanation with effective visuals. I would recommend rehersing/redoing the vocals as it sounds like you weren’t confident or bored. Still a great video, thanks for making it!
My friend.. I know how much effort was put in to make a video.. The animations are so good. You just had to speak louder. Otherwise it's a wonderful video.
You have it reversed, dynamic force on the propeller blade forces it towards a reduced blade angle, not an increased one like you said. That’s why a “pitch lock” mechanism was put in place in case of emergency hydraulic power loss.
Was going to comment on the total lack of a competent Instructor voice ... but I see everyone has driven that point home. Being of Irish descent myself however, Erin go Bragh!

I didn't know anyone did ASMR flight training till now.
u need to increased ur angle of attack in your tongue so you can speak louder
best comment ever
LOOOOOOOL
Ive read a bunch on this and watched a few videos, but yours was perfect and finally made it click for me. Thank you, great simple video.

By far, You're video was effective than any other!!!!!

Finally a video that makes sense. I get it now!! :)

That was awesome. Thanks for taking the time to do that
Awesome explanation! It took me a minute to figure out the orientation of the photo, but after I did, everything else was pretty clear.
If only the volume were a little higher
Excellent and simple explanation. Awesome animation.
Great explanation with effective visuals. I would recommend rehersing/redoing the vocals as it sounds like you weren’t confident or bored. Still a great video, thanks for making it!
I had my volume turned up all the way and still couldn't hear this audio
great video, needs to be louder
Great video! Thanks!!
My friend.. I know how much effort was put in to make a video.. The animations are so good. You just had to speak louder. Otherwise it's a wonderful video.
Great Animation but only if you could speak a bit louder
Thanks, it is a so good video for explain how does the governor work.
Is some1 sleeping beside u?
great vid
Great explanation thank you 👍
great explanation!

Good video
good video but i think the two process is actually opposite for the flow of the oil
Thank you
Thanks

Go raibh maith agat Seamus (James)
so quiet
dude i can barely hear you.. would have been great if I had actually been able to hear anything you said. and yes my volume is all the way up..
Simple Explanation of a Propeller Govenor- "ASMR" i would say :P
Very helpfull, just next time please, speak louder
yall act like you don't have a volume button
Why the fuck is this guy whispering. You sound like a smooth jazz radio host ffs. Good video tho
+Music Kills haha...a smooth jazz host..ha.
This video would be helpful if I were able to hear you.
Bro frig!!! This is a good presentation but y de hell u whispering ?? Wats the secret about
I smell ASMR
x fa tradusir al español gracias
This guys voice sounds like the bad guy from No Country for Old Men
haaha
This is great but why are you sooo Loud:-)? My ears almost exploded
Man good video and explanation! But your voice is so boring!!! With a little bit of attitude would be excellent, do as if you like it
Dang, could you whisper any more. From what I could hear, it was a good video.
talk clearly and loudly !!!!!!!!!!!!!
Cant hear a thing!!!!!!!!!!!!
why are you whispering???????
shhhh guys! he's telling us a secret
Your video would be very informative if you would just SPEAK UP!
Excellent animated illustration but disastrous vocal level. What a shame for a good video to be wasted!
FOR GOD'S SAKE, STOP YELLING!!!
Be vewy vewy quiet 🤫 we're hunting wabbits.... Not even a minute in and I'm out 😖
i got frustrated with your voice volume.
Thanks.. but your tongue is almost stall bro
