Default Wow, Life Happens

Wow, life happens...

Dec. 7, 2017 I went to doctor's office for scheduled appointment after having
spent the weekend in much less than pleasant condition with swelling of my
abdomin. Within minutes my doctor's physician's assistant was wheeling me
into ER due to severe oxy deprivation (34%) to growing list of issues.

Allergies had contributed to what would be diagnosed a completely incorrect
pulmonary functionality, gall stones, and type II diabetes, to say nothing for
consequential effects...of a sedentary life style; any one of which doesn't run
flags up one's medical yard arm...but when they are concurrent, become life
threatening with a capital T!.

Fortunately for me, my doctor had already begun a gall bladder investigative
protocol which included an MRI on the Saturday preceding my going in to see
her on the 7th. Was said I was 4 hours from not flying any more models...

Three weeks later, I left ICU proceeding to transitional therapy to regain my
strength to a level I could begin outpatient therapy to regain strength to now
deal with stresses of ailment treatment and surgery for gallstones if found to
be the course of action. Thankfully and more fortunate than less, the stones
are too large to block entry and exit from the gallbladder...so no surgery.

Made move back to residence on January 23rd where I undergo physical and
pulmonary therapy between the expected poking, prodding, phlebotomy, and
obligatory doctor visits. Rather than interrupt my wonderful medical team, we
are not moving to Dallas but down sizing in Houston.

Sam's Kentucky construction is progressing well despite the ground hog. Our
shop's erected with electricity... The log cabin is under roof with electricity
installed Friday and Saturday before the latest snow/ice storm.

Resolved B-47 canopy issue courtesy of Bob Violett. Will post details with a
visual comparison to 1:1 documentation soon.

Dang Ed. Sure hate to read all this but am happy too hear you're recovering a bit. Hope the strength continues to come back to you.

Default Return From The Light

Not to be over dramatic...but things are a whole lot better than they have been
in a long while :^)

Looking forward to our downsize move and getting back to the B-47 now that a
lot of the Kentucky build out is getting close to completion so Sam can get into
his new home. He and Judy have been on an extended excursion for too long!

Packing my plan sets yesterday showed a lot of what I needed to put in the
"past" as I have changed the direction of my hobby. With the new enterprise
focus on electric powered Giant Scale Modeling there are opportunities to
create competitive flying scale models weighing half or less than traditional
counterparts weigh.

Staying healthy is paramount to enjoying the hobby, whether you are in your
twenties or seventy and beyond.

Where are we now? Glad you asked...

Winging it...

Following installation of the CNC mill in the new shop we get back in the saddle
by cutting spar pockets in the foam wing blanks. I prefer milling them instead
of hot wire as the mill cuts a precision width and depth resulting in a superior
surface to adhere to. Note: That is a "D" spar leading edge in and outboard. It
parts at the inboard engine pylon.

I previously showed how Sam had designed linear servo driven screw jacks for
each control surface memicking the flaperon functionality of the 1:1, shown below.

Default Practical Replication

As for things still to be made (milled)...

While Dick has done a fabulous job "replicating" what he measured on the
remaining B-47's he visited, when it comes to utilizing the CAD drawing you
must "weigh" what is to be "gained" by including it all in a model. Purists will
scoff at thoughts of not replicating everything possible...it is the practicality
of cumulative AUW (all up weight).

If it were not for friends and associates...the B-47 project would never have
an opportunity to take wing. We return to physical progress by Thanksgiving
with Sam's move into what has turned into an epic build of Fort Collins (a
name I have given his log home...aka Fort on top of Mount Collins).

My recent visit to Fort Collins was a welcome respite. There's a lot to be said
for good friends, lower humidity, cool breezes, and the smells of a log cabin
construction deep in the hardwood forest of Kentucky!

Hi Ed, sorry to hear about your health problems; just returned to flying myself after a lot of down time with cancer i.e operations, chemo, radiation. Been some years since I've been on wattflyer, and was hoping to see this B47 in the air.....guess I'll keep tuned to see how she turns out.

Thanks for the welcome...back! Wow, your trek down the jetway to the
pilot's seat had a blessed arrival. We cross taxiways from time to time
on our way to taking wing. The one "flight controller" leads us along our
journey through life. God bless and fair skies with gentle tailwinds!

Friends within this hobby are a reminder we are never alone on our treks.

Default What's Next

I am close to printing all cockpit components, then creating aft end of the two canopies. Canopy is Bob Violett's T-33 canopy extended rearward by the addition of clear canopy parts aft of the rear canopy frame to permit finished conversion to replicate a B-47 canopy, which turns out is 100% scale because the 1:1 B-47 canopy was an altered T-33 canopy.


Next comes scale wheels assembled from William Brothers Model Product off the shelf wheel components and 5.25" smooth contour tires. Off the shelf but hardly standard...they are assembled inside out to provide the recess required to replicate the 1:1 and accomodate Kavan electric brakes.


The brake surface is a drag brake created with fender washers inserted in the recess cavity next to the down struts. Fender washers are drilled 120 degrees out and held in place with chaffered flathead machine screws. Asvoltage is increased to electro-magnet, washer (brake surface) is drawn
more and more to the face of the magnet...slowing wheel rotation.


Outside of each bicycle main pair replicates 1:1 brake tension bar and vent holes around wheel perimeter from off the shelf Williams Brothers Model Products wheel components.

Default Onward and Upward...

Down sizing has been time consuming, replacing items Paulette gave away... Honestly, for the most part we are getting close to being back in the saddle with respect to moving "things" where they are best suited Vs. where initially placed.

This permits me to get back to printing cockpit, and helmets for pilot, co-pilot, and navigator/bombardier. Printing helmets and the navigator figure will result in almost a quarter pound weight savings...the cast metal helmets were extremely heavy.




I need to add a visor and oxy mask w/hose and its perfect.

Default Back In The Saddle Again...RR, Dale, & My Theme Song

Well here it is 11/20/2018 and neither I nor Sam are settled in place yet! I anticipated we would be back on B-47 in a BIG way, however recovery and slow moving carpenters got in Sam's and my way. Its already snowed at Sam's...and he's not in cabin yet!

Its not quite Thanksgiving...Sam's target to get into his new home...though there is electricity and all but the flooring (in process) and sealing exterior surface of logs. Sanding and sealing are progressing...aka racing along with approach of Winter.

Paulette and I have finally settled in the downsizing, well with the approach of Christmas festivities and accompanying decorating what remains is being set aside until January...However, we will return to the new shop this week retrieving stored Christmas decorations and tidy up a bit from rush to store this and that as we moved.

What's next?
(Foot in Stirrup)

With resolve of the pilot, co-pilot, and bombardier/navigator helmet and gear they will be printed along with each of the cockpit components.

..............



.....
The tub and contents have to be created before cavity for them can be hot wired into the top portion of already milled front portion of fuselage.

If you have kept up with this saga...you will know we are working on more than one portion of these B-47's
at a time. Below I bring images together to show how they integrate within the inboard engine nacelle and
pylon.

The first is a dims drawing of how the removable internal Hexcel honeycomb/G10 sandwich pylon blade is
positioned within each of two pylons per B-47. Hexcel pylon blade forms the JetFan EDF mount and insert.
At .20 each there are 16 of these blades in four layups for the two B-47.

The blue line within the drawing below represents the perimeter of the EDF/Pylon blade insert.


Below is the same drawing without its exterior CAD polygons...Bifurcated exhaust is not shown.


An oblique CAD drawing shows how nacelle and its pylon appear when blade is inserted. Bifurcated
exhaust provides the scale appearance of the B-47 with its single JetFan 120mm EDF per nacelle.


An inline view of the nacelle. This is the initial scale replication. In reality the air pathway is by way of bifurcation. The inlet hot wire perimeter of inlet is shown below along with the side view of the nacelle rear.







Initial milling of prototype inboard nacelle produced this. All of which was satisfactory in shape but not large enough for final 1:8.669 scale. The larger nacelle is milled left and right halves not donut as seen in this image. This permits installation of interior pylon blade and EDF with clam shell access hatch.


Your questions are welcome...

Thanks Charlie

Charlie Palmer has 192" of Nomex Hexcel. Charlie donated it to our B-47 project for the cost of shipping it across New Mexico to Texas.
His Hexcel is coiled up in a 12" x 12" x 48" carton. This will go a long long way in the two B-47's.

Applications of Hexcel within our two B-47's:
1. Parachute bays (2)
2. Cockpit box
3. Inboard pylon blades (2)
4. Main gear bays (2)
5. Bomb bay doors and perimeter box
6. Vertical fin king posts
7. Removable surface sections of fuselage.

This new WattFlyer format does not fit well with my early morning mental state.
Its like opening the "A" volume of an encyclopedia and turning a page, suddenly
"P", "R", "V" or "Z" appears.

The topic over-runs are weird when I want to edit a given thread post to add an
additional text or image. Not complaining as I know these things are well out of
reach to all but he who must be obeyed... :^) The cycle speeds are fabulous! So,
in the end its better for everyone.

Default Hexcel Sandwich

I am getting used to this thread software... Or my mind gave up and follows the prompts Any~who here are some catch up points:

Instead of using light ply, bass, or balsa to line the perimeter of cavities in the fuselage a Hexcel G-10 sandwich will reduce weight at the same time being stronger with the added benefit of being able to use brass screw seats to mount items to.
...............................................
...........................
......................................
.................................................. ..
Because tension and compression are equal the sandwich is perfectly flat. When three .210 Hexcel are sandwiched with thin G-10 the result is not only perfectly flat, it is extremely resistant to off axis stress, aka twist. Pylon blades, and linings for bomb bay, (2) parachute bays, (4) retract doors, boarding hatch, cockpit tub, and aircraft I.D. switch plate are easily formed with Hexcel and laminated with G-10 on either side.

Shaping the Hexcel is in the same manner as making a fiber glass hatch. Saran Wrap is taped onto location of area where hatch or door appears on fuselage. This provides a proper curve to Hexcel when G-10 is adhered to it. When cured perimeter is trimmed to shape of hatch, door, and I.D. switch plate. After trimming to proper perimeter each shape is traced onto surface of fuselage. All area inside traced lines is removed from fuselage to provide access. Each Hexcel shape fits perfectly in fuselage cavity.

Default Goodbye Santa... :^(

With the repacking of our new LED Christmas tree, we are officially packed after the first decorating and local celebration in five or more years. After our daughter's graduation and move to Dallas, every Christmas we drove to Dallas to celebrate Christmas. Last year the family celebrated in ICU while I slept.

For me this year Christmas was like Disneyland. All the twinkle, glow, and wonder of modern non-medical LCD technology I even managed to talk Paulette into permitting
to be hung from lower limbs of the tree and allowed to play on three occasions before its bell choir was declared too loud and persona non grata after daughter arrived. If my sharing these Christmas memories seems a wee bit OCD...welcome to my new
