Subject: | Re: There was a time when 488,000 pound airplanes were |
pretty amazing. . .
Many years ago, I flew as a Electronic Warfare Officer crew member
aboard the B-52E on the first exploration of the B-52 in a low-level
mission role as well as many hours on "Chrome Dome" nuclear airborne
alert - at the time, it was the most massive airframe to leave the
ground - now seems like a light weight {:>).
So heavy, that on high density altitude days (and there were many in
Western Oklahoma), water injection to the engines were essential to get
a heavily loaded B-52 airborne. An impressive sight in those days to
see this 8 engine monster hurling down the runway with black "smoke"
belching from the engines, the engine roaring and heat mirage distorting
the view from behind from those engines. Hard to believe how long that
airframe has been flying.
But, yes, 1000,000 lb aircraft is almost inconceivable, but does give
credence to that old saying "....that with sufficient power you can get
a brick to fly". But, I guess this video addresses the question "...
Yes, but can you get it stopped?" Impressive for sure.
Thanks for sharing

I think I used to hear numbers for gross weight on the B-52H
models as topping out near 500K pounds. Here's a rejected take
off test on the 747-8 loaded to nearly a million pounds. This
is what you call "really hot stuff" . . . no pun intended.

Dan,
Those are nice. I've used the wire grip connectors which are also aesthetically
appealing and are readily available at good prices. I normally plug them with
fire-goop from the rear as not to take away from appearances on the front.

Concerning firewall pass-through trinkets...I found a company called Precision
Grommets and they will custom make these in a variety of materials and sizes.
Here is a blip on how I put them in my Kitfox http://www.azshowersolutions.com/Engine13.html
I was very happy with their service and product.

Hmmmm . . . low level stuff . . . did your pilots
have the pleasure of flying that so-called terrain
avoidance radar?
I worked on a crew tasked with aligning the radar's
display processor (lots of vacuum tubes) on E and
F models being recycled through Wichita for
upgrades. It took 3 shifts to run the alignment
procedure during which it was not uncommon to take
3 or more modules up to the lab for "repairs or
adjustment".
Those might have been infant mortality issues. It
was a brand-new-out-of-the-box processor
from Raytheon. I often wondered what the failure
rate was for these things in the field. I hope that
nobody ever had to fly head-down with one of those
things in anger . . . it didn't take much drift
to use up those 200' margins for clearing the hilltops
and/or keeping your wing tips off the canyon walls!

Bob, I really can not recall for certain the reliability/reliance on
those early terrain avoidance systems - best I recall they were
acceptable - but at that time don't know too many pilots that actually
trusted any "gadget" to keep them out of a hillside.
I do know we had the terrain avoidance systems - however, for peace time
exercising/training - the routine required for one of the pilots to
exercise "eyeball terrain clearance" through the wind screen at all
times.
As best I recall, if we had ever gotten the "GO CODE", the thermal
curtains would be pulled around the cockpit windshield - and flash
goggles would be worn by the pilots. However, I do recall there were
some situations where one pilot (the co-pilot naturally {:>)) was to
pull away the goggle from one eyeball, pull back a portion of the
curtains and keep one (presumably sacrificial) eye ball on the outside
world.
But, its clear that terrain avoidance has come a long ways since those
days as have all things electronic.

Yeah, 'trust but verify' . . . solid advice any time,
any place.

Boy, you got that right! The imaging, computing and
sensing technology in 2011 kids video games is more
sophisticated than the-best-we-knew-how-to-do on the
B-52 in 1960.

For all the precise engineering and science in manufacturing, it boiled down
to this. I was a navigator in the B-52H. So here's this 22 year kid,
taking readings from the pilot, plotting the data points and drawing a line
to determine the TA (terrain avoidance) correction feeling like he was
inside the paint shaker at the ACE Hardware store trying to keep his lunch
down halfway into a 16 hour mission. Precise? I'm just glad I didn't have
a window.
All kidding aside, we did have write-ups, but the overall feeling was that
if it kept us below Soviet radar, it was worth the effort.

Knowing guy on the other side of the wall has sticks

Roger that! I am convinced that this hobby has kept my 71 year old grey
matter from eroding away - trying to stay up with the latest changes in
just cell phones, Tablet computer, and other consumer products, much
less microchips, lasers, solar cells, etc, etc, etc, is impossible, but
certain is exciting to try.
