My next nasa wing

Hi guys was wondering if anyone has made a NPW-HA im very interested in this kind of nasa wing but was wondering if it was any good or not thank you josh

cool thank you

It has been a while but this is what I am working on now to bring to nabx. This is the center panel for a npw9 9 meter.

Here is the latest kite I made. It is a npw9 2.25.



Susan (npw goddess)

This is what I am working on now. It is now finished. Ready to move on to its new home.



Susan (npw goddess)

Been working on a new kite. It is a 10 meter. Here is a picture. I just need to bridle it.



Susan (npw goddess)

Lookin' good Susan

Your NPWs are top notch...

It took me a while to take a picture of the finished 10 meter. Here it is.



Susan (npw goddess)

My next kite project. It is a npw9 4.5.



Susan (npw goddess)

Here is a picture of the 4.5 all done.



Susan (npw goddess)

nice!

Albeit probably trivial for you... do you have patterns and bridal instructions for npw5's? I'd say 9 too, but I don't that'll be my first one

Working on a small one right now. Npw9 1.2. Needs the darts sewn and bridle lines.



Susan (npw goddess)

Npw9 1.2 finished. Here is a picture.

now I want to see the purple color,

Am I the only one that has to wait for like an hour for this one topic to load up? 3 million responses and 12 billion looks. Got to be the all-time best of the best, way ta go Susan.

I finished up on the 2.5. Here is a picture.

I started on a 3 meter npw3 in shades of orange. Here is a picture.



Susan (npw goddess)

Here is a picture of the 3 meter npw9 finished.



Here is a picture of the 3 meter on top of the 6 meter npw9.



Susan (npw goddess)

I like the colors :bigok:

Any idea of how many you have made? (may have asked this before, you may have answered before, if so sorry dont remember)

I finished up a 6 meter npw9 last week. Here is a picture.



Last night I finished a 9 meter npw9. Here is a picture.



I took a picture of the 3, 6 and 9 meter stacked on top of each other. Here is that picture.

Cooler? Want to pick a date.. say in October? Linda is having her knee replaced at the end of August... so maybe by October she'd be ready for the beach

Hi,
just thought I'd post a couple of my latest builds up. First is an 8m NPW "Batman:





Latest is my 11.8 NASA parawing:



This shot was taken on it's maiden flight, tweaked the nose bridle to give a better shape. Now working on depowering it!!

Nice

@bigE123, Susan: did you noticed my post on arcusers.net about a single skin arc kite ? its a sort of a nasawing but with no bridles :

it would be very interesting if you experienced kite builders could build a prototype !


@bigE123: i am looking forward to a video of your NPW21 kites in flight !

On Herc's post of Single skin arc..

Well I finished up my latest project. I made up a 1, 3, 6, 9 and 12 meter npw9 kites for a friend. Here are a few pictures. First is the 12 meter.



The 1 meter.



All of them stacked on top of each other.



And all bagged up.



Susan (npw goddess)

wow, you even numbered the bags, how cool is that?
Nice colors, I like a matched set.

When are you going to sew a little tag on each kite to show the size and date and creators name?

That's a sweet stack of sacks! +1 for the tag with size/date/creator's name (+e-mail, for possible orders? I always brag up your kites when I'm flying them!)

Thanks guys for the complements. I am sewing my logo on the kites now.

Got Green

This is what I have been working on this week. It is a 7 meter nasa wing.



Susan (npw goddess)

While some of yall were out playing in the desert I was home sewing up a new nasa wing. Below is a picture of the npw9 10 meter in blue and orange.

Latest build and first test flight, it's a NPW21 although as it's got a wider body than standard it could be a NPW 23 ;-)

It's 3.1m2 with a "Z" bridle fitted, grabbed this photo so that I could use it to check bridle tensions etc.



You can see the "Z" bridle better on this one along with the cascade bridle

Thought I'd make this build fairly standard, but just had this nagging in my head...... so I've put a "C" bridle on as well :D
Give a much better wing profile. IMHO

Well it's been awhile since the sewing machine has been out and I've been thinking about how wide the NPW21 can go without losing it's character as being a very stable kite with no nose collapse.

So hot off the machine is my new venture a 6.8m2 NPW 21 higher aspect kite. For this I'm going to bridle it with an extra set of lines to the center panel as it's over twice the standard width. Fingers crossed, I'll update when it's finished and had a test flight.

I love that graphic!
Nice Job!!

Thanx for the comments

Had my first test flight yesterday...... First off it didn't fly, after 1/2 hr of altering some line lengths it lifted to @ 10ft and sat back down. Lengthened the brake lines and up it went. First impression was it needs the handles held like a foil (power line between fingers), it flies with no brake input at all!! Which I assume is down to the wider body panel, there's still some tuning to do but now that it flies it proves the concept works :D
From my initial flight the kite is very stable, nose is well formed, it turns well either on one line pulled, brake input or both together.
To get the kite flying I disconnected a brake line I had on the TE middle of the wing panel, this resulted in some TE flutter on the wing and center panel which is obviously also due to the fact that it was flying with no brake input.

A bit more tinkering and I'll post up some pics and get a bit of vid. Looks very promising!

And it flies!!! Big smug grin :D

Just a couple of tweaks needed and I'm sure there's a bridle caught on the picture.



Now just waiting for some new line so that I can get rid of the temporary lines with lots of knots for adjusting.

The problem with braided nylon is stretch, it'll stretch with the load, that's why bridle line is more expensive it is a static line (very very low stretch) and the breaking loads stated are a minimum where as nylon etc is max load after stretch. With no stretch on the bridle lines you will get a much better profile and control.
As for the seam reinforcement, I use webbing 12mm if I can get it, 15mm is widely available, I roll the seam around the webbing, the seam becomes a bit wider but it does give a very stable edge. The breaking strain for webbing is @270Kg, obviously there is a slight trade-off in weight, but I much prefer the stability it gives and it means any holes put through the material for the bridle points goes through the webbing so there is no tension on just the material.

Thanks for the quick reply! I think I'm going to try a slightly smaller kite first, and work out the kinks.
I did think about the nylon stretch after the fact.
Do you use the webbing on the sail/wing seams as well?
Do you think the 1.4mm line would be okay for seam reinforcements atleast? I'd love to be able to have another use for the slightly ridiculous amount of cord I have The point of the line in the seam is to bear most of the strain from bridle lines right? So it wouldn't all be on the sail material? Has anyone tried a hybrid of line-reinforced seams, with inch-ish long ribbon/webbing located at just bridle points? Or does that result in an uneven look in the sail? Is that what you meant when you said "tags" in your above post?
Would it be just as much work to sew loops into the seams that protrude from the seams?
I've also already hot-cut all my pieces to allow for a 1cm seam...so I'd have to find 9 or 10 mm webbing/ribbon...
While I'm looking around and comparing, what's a decent price for bridling line? And can I use it for flying lines? I can't seem to find a clear answer to that..I keep seeing stuff about sleeveing.
Mind you, I've not yet gotten into buggying or anything really. I'm just a guy who likes kites, and my penchant for activities might take me into buggy or boarding or what have you...
Sorry for all the noob questions, I tried looking through the main forum, but there was alot there. Wish there was a DIY subforum in here...

Thanks for any help ya'll can give me! I'd rather be annoying than blindly use what i happen to have just to see it all go horribly wrong!

The webbing I use on all seams that have a bridle on

Do I think the 1.4 mm line would be okay?... tough one, I would say at a guess yes.
Yes the line is to spread the load across the seam rather than the material taking the strain.
When I used the term "tags" what I do is burn a hole through the seam and thread a piece of 60 daN bridle through and make a loop with a stopper knot this gives me a point to connect the lines to.

My first build I did sew loops into the seams for the bridles, do a search on the net for NASA parawing building there are some good techniques on building.
If you already have cut everything out I'd do loops into the seams.
Bridling line is just that, not for use as flying lines it's not as supple as flying line.

Good luck

Well this build certainly caused me some problems! Just could not get the kite to fly up to the zenith, there was something holding it back, after many minor mods, just could not crack it. So with a final throw of the dice removed my extra bridles and went back to basics and rechecked all my calcs etc. The upshot appears that an NPW does not like it's profile flattening out, it needs that classic "hump". Shortened my A/B bridles and made a modification to the nose and hey presto a reformed higher aspect NPW 21.

And finally:
Here is my modified "NASA" NPW21, it's 11.8m and now sports a 5 point bridle keel, reducing the centre panel bridling from 10 to 5 lines, a modified profile and a depower system.
I initially had some problems with nose collapse on low AoA but that is now sorted out by modifying my de-power system.

Could this be the final mod? The window on this kite is the best of my NPW quiver, it will sit absolutely dead overhead right on the edge of over flying on it's low AoA. May re-visit the wings by altering the AoA on them as well, as I keep them fixed to stop any wing flutter but for now this puppy is ready to use again.
