F-22 Raptor at Oceana Air Show 2010

The F-22 demonstration didn't go as planned. The Raptor flew in did a quick vertical climb and did an almost right-angle turn due to its thrust vectoring capability. The announcer then said the aircraft had develolped a problem and couldn't finish it's demonstration. That was disappointing.

Blue Angels at NAS Oceana 2010

Hey all,
Just back from a tremendous weekend at the annual Naval Air Station Oceana Air Show. My friend Chris Dover and I drove down to see the show, hear the roar, and smell the exhaust. The Blue Angels performed, and as always, did a superb job. Their job is to take normal manuvers and do them FAR lower and closer than normal aviators. This precison control and skill is a hallmark of the Naval Flight Demonstration Team.

The Blue Angels in their "Diamond Formation" there is only 18 inches separating the canopies from the wingtips.

Blue Angel 5 banks hard.
Notice the contrails forming over the leading edges of the wings. As the wing angle of attack changes during the turn, the air can't fill the void fast enough and clouds form in the low-pressure areas.

Lead Solo Lt. Commander Frank Weisser and Opposing Solo Lt. Ben Walborn cross during opposing minimum radius turns. They are closing at many hundreds of knots (800+?) and pass within feet of each other. Phenominal skill and nerves of steel are nececessary. (BTW - I'm proud I timed the shot just right. My Nikon D90 is so fast and responsive that it makes shots like this possible. I love it.)

All 6 Blue Angles form the "Delta Formation" and complete other manuvers.

The Diamond Formation breaks on the "Boss's" (Capt. Greg McWherter, Blue Angel 1) command and the aircraft maneuver independently.

If you get a chance to see Blue Angels in action you should. What a show.

Peace,
John

USS Wisconsin

On our way to the Oceana Air Show we decided to visit the USS Wisconsin, an Iowa-class battleship.
Wow.
That was cool. The "Wisky" as she's affectionately called, served with distinction in WWII, as wells as the Korean and Gulf wars.
That is one BIG ship, and her sixteen inch main guns can hurl a shell that weighs as much as a Volkswagen twenty-one miles.

More soon.
Peace,
John

Hard at Work

A bumblebee was hard at work gathering pollen when I came out the door this morning. Isn't God's creation marvelous?

Me Her Us

Hey all,
Here are some pics of us we've taken recently.

Tomlin and I are hiking the Appalachian Trail. No problem as we hiked from the parking lot to the trail :) We took this in Shenandoah National Park along Skyline Drive. What a beautiful place.

Sweetie at Windrock recreation area.

Gayle on the Appalachian Trail.

Us at Windrock.  The Wind Turbines are really cool.

Us on the AT.  We had a really fun trip.

Life is good.

Video of Wind Turbines - TVA Buffalo Mountain Wind Power

These wind turbines are so awesome.  Watch their graceful motion and listen for the "whoosh" as those massive (100+ foot) blades sweep across the sky.

  

Cool.

Peace,

John

PS - geek moment.  I got to wondering about the whoosh and did a little math.  If I'm right, the blade tips are moving at over 100 MPH!  That will certainly generate enough turbulence to be audible.  

PPS - super geek moment - With 100' blades the tips scribe a circle with a circumference of 628 feet (2pi x radius) we timed 4 revolutions in 15 seconds making it 16 rpm.

16 revs x 628' = 10048 fpm

10048'/5280 = 1.9 miles per min x 60 = 114 MPH

If the blades are 134 feet (as I read somewhere) the tip speed is 153 MPH.

Windrock Wind Turbines

Took a really cool drive up Windrock mountain to the wind farm today. The tubines (windmills?) are huge but graceful as they sweep across the sky.

Climbing the mountain you can't see them until you are almost there.

Those blades (each over 100 feet long!) were really moving. We clocked them at 16 rpm which is quite fast for somthing that big. Our friends Billy and Karla, whose Jeep we rode in, said they'd never been able to hear the "whoosh" of the blades so clearly. Check out the video to see/hear them.

These turbines are part of the Buffalo Mountain Wind Farm, a TVA "green power" project.

They are like kinetic sculptures. I think they're really quite beautiful.

I appreciate Billy and Karla taking us up the mountain, it's part of a large off-road recreation area.

Peace,
John
