I was out flying last night for about an hour...it was in the high 70's. After I landed I was post flighting and was checking to see if my rotor blades had picked up many bugs. I noticed that on the outer ends of my blades ...there was a noticable temperature increase. I dont know why I have never noticed this before...I guess I just had never run my hands down the blades after a flight. You could definately feel a warm temperature at the tips and then about 4-5 feet in...it was cooler...and the inboard section had a cool touch. Interesting...to me anyway... :rolleyes:

Hey, thats neat, an automatic rotor deicer. :D :D
 
All you need now is ice Stan. :D
No,on second thoughts,you don't. :(
But I agree,it's interesting.
As if the "driving" section is cooler than the "driven" section.
That reminds me of something. ;) :rolleyes:
 
hight speed tips! produce heat! : D

hight speed tips! produce heat! : D

speed of the tips: 500ft./s (280 mph to 415 mph for the advancing blade)
What you need and get 15% more efficiency: :eek:

The tips of the blades move the fastes through the air, therefore the most friction.

THe inner parts of the blades move more slowly in the air, less friction.
