B-17 Sighting!

that'd be my guess as well, probably keeping hydraulic accumulators pressurized. That'd be another fun thing to add to the FS soundscape.

Excellent Paul!

Thanks for sharing your experience ...

One day maybe I'll get my turn ... :kilroy:
 
My sources:)wiggle:) tell me... that you would be correct....hydraulic accumulater.. It is an interesting sound the first time you hear it... pretty loud if you can hear it over the roar of the engines...
 
Thanks, Witt! Actually I only heard it while taxiing, when the engines were at relatively low power settings. Plus, the device making the noise was pretty close at hand on the flight deck someplace, evidently. Or right below the floor boards. During taxi I didn't have my hearing protection headset on because it wasn't that loud, and this pump noise was quite distinct. While in flight, with the engines at flight power settings, and my hearing protection thingies on, I never did hear it. But maybe it only operates on the ground. It was pretty loud...

I found this in my B-17 pilot’s manual. The tank shown looks just the one the flight engineer pointed to when I asked about the noise.
 
If you are looking aft from where you were sitting, which would have been straight forward the way you were sitting, it would have been just left of the door... I thought I had a picture of it somewhere but can't find it...
 
Just as another heads up....Liberty Belle will be at Mt. Comfort just outside of Indianapolis through the week and this coming weekend for those of you in Indiana... Come out and see us..... Next stop, Columbus....

Anybody from the Indianapolis area around here? Can't remember any...
 
It must be fun traveling with that plane as it flies from city to city!
 
Unfortunately I don't get the pleasure to do that Paul... other than an occaisonal jump from one city to the next when they are near by...Look for pictures in about a week....:wiggle:
 
Hey Paul great pics of the flight.....is that the kid that got sick????, the one with the plugged ears??? were you sticking your head into the wind???...nice day.
 
Paul, did you at least take your ear protection off at least once while up in the air? It is a great sound even inside... I don't think I have ever worn any protection myself... First time I flew back in '05, my dad told the guy taking us up to skip over my brother & I when passing out the ear plugs.....

(See Note 1)

Note 1: :eek:

I guess that's ok for short periods of time...

Actually I did remove them for a bit, while up front, just to see how loud it was. It was loud. :d My hearing is FUBAR'd due to spending way too much time around navy jets over the years, without hearing protection (see Note 1) so I try to protect what I have left... I don't think the hearing protection altered the experience that much. There was still the immense power that was felt as much as heard. The sound comes through the airframe in the form of vibrations, and the protectors just turned the volume down a bit. I could still very clearly hear the deep bassy "note" of those four engines, and it was quite impressive indeed!

On a related note, between the Wings of Power B-17 and the Donationware version by Gramps and Co., I thing Gramps got the sound closer. At high power, the Donationware sound is almost dead on perfect. At low power I think neither properly captures the "machanical component" of the sound.
