"The Vulture Page"

Featuring the NPW9b

 

     I’m assuming you’ve seen my NPW Home Page for NPW’s and where a TON of alternate building information is given for ALL NPW kites.  If you haven’t, have and look and please… if you’ve any additional suggestions, tips, or other ways of doing things & are willing to share…. Share it with us for everyone’s benefit!!  Contact ANYONE mentioned in these pages and we’ll make sure it gets mentioned and possibly published on one of our web-pages.

 

    So on with the NPW9b, which is the newest progeny of the Rogallo wing.  The NPW9b is an upstart, muscle-bound cousin to the original NASA NPW5 and NPW9.   In looking for a way to make a totally “no waste, whatsoever” NPW5, I stumbled across a way to do it… save material, and make a kite completely out of one piece of material of ANY given width.  I also found that I had independently “discovered” a hybrid NPW9, but with a much wider center panel ~ half again as wide - hence the name NPW9b because there was another similar kite that had just come out on the open market.  The name “Vulture” was born of an offer I made publicly to make an eNPW5 Vulture if someone else was willing to front the materials.  I had 2 takers at the end of a period of over a year.  At that time I was heavily into developing the newer NPW9b with several other kite makers and the NPW9b “Vulture” was “hatched”.   This “NPW9b” ended up as a result of many ideas from other folks interested in the NPW kites. 


     On this site I have posted some hints and tips for helping you get in the air faster and easier… just as I did with the NPW5 pages last year.  Initially, the NPW9b was an exercise in trying to save material for a friend when he had hoped to make NPW5’s en mass for a unique commercial purpose.  There’s a schematic on how to do that below.  The plan can be used for any of the NPW family of kites - the difference being deciding the center panel width, leaving the upper or lower corners of the sail in place - or not..  Then it’s bridled accordingly.

 

This is the basic plan of the NPW9b

 


 

     To the left is an inspiration I had for an NPW kite for quite a while..   You can see the face has changed considerably to the NPW9b Vulture because I kept playing with the eyes and wanted to make Mr. Vulture a little more “pissed off” looking….   I also wanted to fall in about the 3.0M^2 area, or thereabouts in size.  I knew it would be larger in size than the NPW5’s for the same height, or keel length, because the center panel seemed “pinched” or too narrow to my sense of balance and aesthetics   The center panel is now considerably wider than any other of the NPW Family, by comparison, and the result is considerably larger in area …   Almost a half a square meter bigger.  It soon ended up being a 135Cm tall, 2.7M^2 NPW9”b” with the Vulture face below.

    Andy Hook of the UK was the instigator of the Cascade Bridle, and Stelios (Greece) was responsible for the addition of the extra set of bridles in the middle of the wings.  JP Gleyzes (France), Jacques Bayman (South Africa), and Tom White (Canada) were the miracle makers with the math and programming for the kite bridles.  Tom, especially, not only made a fine NPW9b program as did JP, but he was also willing to accept the first NPW9b prototype from me for tuning.  (I don’t have much wind in Phoenix, Az.)  He took it and tuned it to near perfection.  Fredrik Lejonklou has even further fine tuned the NPW9b sail.  We couldn’t have done it without US and ALL our efforts… Thank you one and ALL.  Kudos, kudos, KUDOS!!!  

     JP’s program (with Fredrick’s profiles) is definitely for the designer and Tom’s program is for the builder.  If you intend on making this kite, you HAVE to peruse both sites and these fully functional programs.  The information to be had there is invaluable.  Note that the bridles can be swapped from one program to the other… the sails are the same in both.  See JP’s site at http://freedom2000.free.fr , and Tom’s at  http://members.shaw.ca/kiteman/ . 

Also an added feature, Tom is working one an NPW-HA.  This is basically a 9b, but has 3 center panels and bridled accordingly.  Look for the program soon on his site below…  You can see a pic of the HA on the Vulture 9b gallery.  It’s the blue and green number just below the Vulture at the top of the page.   The inventor of the HA is Jan Claes and you can see much more on his site at :   http://users.pandora.be/claeskites/page5.htm. 


  Enter Larry and Karen Green… 

Below is the first newly finished and unbridled prototype sail of an NPW9b “Vulture” made by Larry and Karen.   It’s similar to that of the new, much improved commercial models of the NPW9, but the similarities stop there.  The NPW9b is fully appliquéd, has a Cascade Bridle (less frontal line area in the wind to slow it down), and because of it’s larger center panel, for it’s size, this little sucker will haul your ass all over the field in a 10-15Mph wind!  The first few NPW9b‘s have a 33% wider panel, but the final units have a full 50% increase over the original on which this design is based….

  I wished I was a buggier because Mike Dooley and I think this NPW9b style kite is a very inexpensive buggy engine.  I haven’t used it as such, but Mike was VERY impressed with it in San Diego, recently. Its abilities are far superior to the NPW5 and it will go a lot further to the edges of the flying window.  It isn’t a foil, but at 1/10 the price if you make one yourself, or at less than ¼ the price as compared to an equivalent sized foil, you can’t beat an NPW of ANY persuasion!!  And you get a lot more bang for your buck with an NPW9b!!  So unless you’re into competition buggying…. make one!

    More time went by online chatting with another NPW phreak like myself…  Larry Green.  Between the two of us the present and final version of the “Vulture” was born, or better yet, hatched.  Below, Karen does most of the tuff stuff; Larry sews the straight runs.  One can see that the work is exquisite.

 

 

 


Below are some of the Vulture Family Variants (or ought I say “Deviants”?) that came from Larry’s very pregnant mind.  Most of these have already been committed to the needle and Ripstop. 

Neat, huh? If you have any questions about the building or sewing of these special kites, contact Larry… ( Click Here)

 

   

 

 

 


 

 

     Here’s the man who is basically the “Instigator” of the NPW9b, so to speak.  Stelios Alexandrakis and I capitulated online for a long time over several alternate ways of making NPW5’s and bridling them.  Stelios came up with the center “C” or “M” bridle.  I don’t know where he got the idea, but it was just before the commercial NPW9’s were on the market.

 

    The standard eNPW5 (I think) to the left was the predecessor of what was to be.  Stelios added the extra bridle to the middle of the wings, (below, right) pulled the middle harness in a bit flattening the sail considerably, and a hot kite was born. 

    

    Stelios got the idea to duplicate the 8 bottom lines from the “A” panel of the DeJong plans and add that extra set of lines to the points you see below. The little white points show well on the right wing in the middle.  This flattened the sail considerably and was very successful, but not THAT much better!!  The flatter he made the sail the better it became!!

 

     Then Stelios dropped out for a while… something to do with possible commercial development of his kite… I guess it never happened because he’s back now.  Thanks to Stelios, we can all benefit from his first ideas. 

 

     Can you, at all, imagine flying the kite to the right?!!  12 square meters of converted NPW5/9!!  The winds on the Mediterranean Sea must be gentle and mild.  Note the NPW5 above is full of air and Stelios is not even leaning backwards!!   The NPW5/9 to the right is beginning to fill out and I’m sure this is a very LOW WIND kite, to say the least!!  I know what a 2.7M NPW9b pulls like in just 10-Mph winds and 12meters will not stop for ANY man!!!  It’s a locomotive on strings!!

 

Stelios’ website is one of the most comprehensive around for guiding you to make your own Wipika type kites, too... and the board, if you can speak and read Greek!!  He has a program he has written to make a Surf-Kite similar to the Wipika, and even shows how to make the bladders for them.  Click here for his website and have a look… There is a lot more than just kites……


    Lets jump ahead several months and go to Tom White’s home in central Canada.  As I mentioned before, I had already made and bridled the NPW9b with a 33% wider center panel and Cascade bridle.  I had only flown the new NPW9b a few times… only 3 or 4 times in about 2-3 MONTHS!!  Phoenix doesn’t get much wind at all.  Out of frustration I asked Tom White if he would be willing to take on the tweaking of the bridles of the new NPW9b since he had TONS more wind than I have here.  He was willing… (God bless ‘im!!)… and I shipped it to him.   Now realize the bridle testing was done in the dead of winter on the snow-swept prairies of central Canada!!!  Talk about commitment!!?

Below are a couple pix of that very first NPW9b hanging from the ceiling in Tom’s den.   This is a great idea to get a feel for what the sail will be like when in the air.  It also allows one to even up the shrouds without measuring.

 

         

 

Thanks again, Tom for all the help!!


 

Cut to the parking lot behind Larry Green’s place.  The fruits of those several months of emails, drawings, and general yakking has produced the Vulture you see in these next few pix.  Below is a small gallery of the first few flights of the NPW9b Vulture.  That’s Larry on the ground.


 

 

 

 

 

And here’s my latest pix of MY Vulture… Not a lot different, but the sky is blue!!
