Next from Lionheart Creations; Boeing 797 Blended Wing

SOH-CM-2014
Hey all,

This is next. This is a freeware (first release) that will be first for FS2004, then later for FSX. This is the flying wing Dreadnaught from Boeing, the 1000 seater 'Blended Wing' Boeing B-797.

Doing it for a friend that doesnt have one for FS9.

Freeware will not have a VC. (arrgh, spit! how can you do that??? ACKK!!!) yes.. bad news, I know. We will have a really nice 2D panel though.

I am already into negotiations with Boeing and about to submit the official license application which will enable me to be an official, legal Boeing flight sim representative. Then I can do a high detail VC, super detailed FSX version, and also make the Boeing Bird of Prey... (I want to make that one bad!)

This flying wing is actually beautiful. With the engines off the top, you see a very sharp design. The front cone looks a bit awkward, like it still has some 'tubeliner' in it, but the rest is awesome.

Note, views are work in progress. Front portholes or windows are crooked. Still mapping it.

Very cool!

Good luck on getting official blessing from Boeing. That would be awesome! :jump:
 
does anyone know what the weight of a square foot of composite materil is?? ( about a half inch thick??? )

If I remember correctly from the show Factory Made a completed carbon fiber Trek Bike frame weighs 2 or 4 lbs. ( I can't remember which ) So composites don't weigh very much at all
 
Thanks gang.

Pam,

I have no idea, and there are several composite materials out there to choose from. The A-380 uses a dual aluminum set of sheets with a odd core material. Some are carbonfiber skins with honeycomb core, etc. Oddly, the 380 skins looked like a thick sheet of solid material, like plastic or something. Really odd stuff.

I seem to recall a fairly good BWB back in the days of FS2000 or 2k2, I can't remember. It is quite a facinating design.
 
in 1992 when I was working for America3 (cubed) in the Americas' Cup Challenge here in SD - I had the opportunity to visit an autoclave.

The sailcloth you might remember was referred to as 'cuban fiber' because of our team name and the fact that these were the first non rigid sails made of carbon fiber weave...and the panels of sailcloth had to be baked in the autoclave as part of the process.

At the 'clave I was handed the nose cone of an F-16 - a fairly large fairing when you are holding it - and it weighed about as much as a hard boiled egg.

The carbon fiber sailcloth was innovative because it was so strong and light compared to the materials that were traditionally used prior to our challenge. You could park a buick on the cuban fiber mainsail and lift it with a crane over and over again..and the sail would not tear...also - a rolled and folded mainsail would typically require 12 men to lift and carry it, but the cuban sails could be handled easily by 4 people.

The autoclave was an experience on its own - basically a giant pressure cooker.
you had to lay the sail panels on this 20' long cart - then bag the whole thing - attach the vacuum line and pull all the air out of the bag...then roll it into the 'clave making sure the bag was sealed properly as a failure in the vacuum bag would ruin the panels -

after all was secure and a headcount completed to be sure no one was inadvertently sealed in the autoclave (it had happened before - dude was cooked like a chicken with the meat falling off the bone according to the news article taped to the control panel) the huge round door is closed and latched like a vault and the heat is turned on (450deg for 12 hours if I remember correctly) and the psi dialed up a couple of atmospheres.

Another article taped to the control panel was about an autoclave accident where the operators had failed to notice a stuck valve that was allowing the pressure inside the cavity to continue to rise past the mark it was set to level off at -

well the 6 ton door blew off and landed 3 miles away

fun with technology


Lionheart - I hope to fly your model in FSX someday - the BwB airframe is the next generation of airliners and a natural progression for safe, manned powered flight

Me too, there was a Lufthansa BWB I had long ago that flew ok in 2002 Pro - still available from Fsim.com - just search for BWB. Could you really get an aircraft pack weighing less than 1Mb back then...

Was your "flat cockpit windows" thread at FSDEev about this model?

Did you do them with "shape merge" now?

Hey Bjoern,

I ended up mimmicking the prototype Dreamliner B-787 windshields. I loved those and did something really similar. Very exotic looking. I was going to do the flat windows, and when researching the windows of the BWB, I found Dreamliner renderings and in an accidental auto-non-controllable-druel, I decided to opt for the Dreamliner version.


Bjoern said:
In any case, the model looks very smooth.
I won't fly it though....too big for normal airports. :d

Its the same wingspan as the A-380. :d The track widths of the undercarriage is the only issue so far.

A little off topic but funny!

When I worked in the wheel and tire shop at U-Tapao we used a cage to air those big tires up to 750 PSI. The cage was right next to the office door and we often talked about what would happen if one blew.
We had a SSgt in charge that none of us cared for so one night, we put in a outrigger innertube (the only tire on the B-52 with a tube and rather small) in the cage while he was in doing paper work, hooked it up to the air, turned it on, and left. About 20 min later there was this tremendous bang that shook the whole hanger!, we went running to the office (with innocent faces) to find the sgt outside on the door on his hands and knees with wet fatigues, front and back.

Oh, the stupid crap we used to pull when we were young and had no common sense

(If the guilty party happens to be reading this after all those years, it wasn't my idea!)

It's highly unlikely that this design would be used as an airliner, perhaps as a cargo transporter, but very few seats having access to a window or even close to a window, passengers would be far too isolated. Combine that with large offsets from the centreline and we have the makings of a new super vomit comet.

in the BwB every seat will be a window seat...with multiple HD views of the outside environments from POV's to the side, rear and front of the aircraft. I'm thinking the forward view - which you do not have currently in any tubeliner - will be the most relaxing and least 'upsetting' to the average passenger.

with a theater like seating arrangement I would expect inflight movies to be an altogether new experience

As Bjorn said - the only real impediment to the BwB movement will be the cost of completely altering the terminals and taxiways to handle the extra wide overall span these planes will have
 
where does the wt-9 fit in the schedule?

The BWB will be a great add-on, but I was wondering where the wt-9 fits in the schedule?

thanks
 
The July issue of Flying Magazine has a nice article about Vincent Burnellis lifting fuselage and the experiments Boeing is having with the Dryden Flight Research Center, X-48, the Blended Wing Body or BWB for short.
It is a 500 pound, 20 foot wing span with three 50 pound thrust model jet engines mounted on the trailing edge, much as Bill has shown here. They've gone through the first phase of 140 flights. Phase two will be two model fanjets moved futher aft, flanked by two verticle fins.
Although the BWB keeps popping up on the Internet as Boeing's next airliner, Boeing is making no such claim. One of the biggest problem is pressurization with a flat ceiling and floors.
 
they'll just have to have cylindrical compartmentalization of some design for them.. I'm going to be estimating weights on the full scale which is i believe five times larger ( but dont quote me on that ).. Thats why it got complicaterd for me..
 
more of an oval shape for the pressurized passenger section...like a very, very wide tube in cross section...with the remainder of the internal wing structure for baggage and fuel

_______________
(________________) rudimentary depiction at best mind you

the top and bottom of the oval would be convex and concave to a degree to help balance the pressure which would also allow for much more headroom and the opportunity to reduce the claustrophobic effect that most tubeliners induce..
