2e5.com is a site where I share some of my research, hobbies, and experiments. Here you will find articles on kite design, programming, and NASA technology.

The latest articles on this site:

• NPWC Falken a sparless bridleless single skin kite design in the NASA parawing lineage.
• NPWC Falken plans plans and construction details for the NPWC Falken.
• Maeko: a sparless SLE single skin foil hybrid.
• Wifi Configuration Using Tomato firmware to create a reliable wireless internet connection.
• Site Feed Creating a site or blog Atom feed — a low level description.
• V Plotter Design Math and code for designing a minimalistic plotter.
• ssh Configuration Setup and configuration of an openssh client and server.
• Volkite: two skin foil construction on the leading edge and single skin for the rest of the canopy.
• Fanø 2009, the 25th anniversary of the Fanø International Kite Fliers Meeting.
• Yagu SLE a ribless two skin sled kite using a SLE (supported leading edge) bridle.
• Rata Jet A new iteration in the Rata Wing series, showing glimpses of higher potential.
• Yagu is a ribless two skin sled kite which can be flown on 4 lines or as a single line kite.
• FoilNose 3 increase L/D by incorporating air chambers on a single skin kite.
• Rata Wing Kite A sparless single skin kite which might have some potential.
• Single Keel Parawing - Research gathers the information necessary to create a single keel parawing kite plan.
• Little Dragon development of a NPWC kite using a ram-air tube.
• Lift to Drag Ratio explores an important concept in kite design.
• Kite Design Parameters of the program shown in the Parametric Kite Design article.
• FoilNose 2 continues experiments to increase L/D by incorporating foil sections on single skin kites.
• Kite Links to Parawing related sites.
• Barish Sailwing reviews patents and NASA technical reports related to Barish's Sailwing design.
• Everett Parawing shows a patented foil nose parawing modification which gives a resulting lift to drag ratio of "approximately 3.7 or more."
• NASA Parawing Reports lists all electronically published NASA reports on sparless ("all-flexible" or "tension-structure") parawings.
• NASA Parawing Profiles line length data is processed to produce profile outlines for NASA Parawing models 5, and 19-24.
• NASA Parawing Research a review of NASA's twin keel parawing models 1-24.
• Denmark Vacation visiting H.C. Andersen's House, Egeskov castle, and Skagen.
• Parametric Kite Design using Rhino CAD and the Python programming language.
• NPWC 2 Line Bridle The NPWC v7 is made easier to fly by creating a simple bridle. Includes a prusik knot pictorial.
• Fanø 2007 I took some photo's at Fanø 2007.

Selected older articles:

• NPWC foilnose One part NPWC, one part foil. Only the nose of this NPWC is a foil, the rest is single skin.
• NPWC v8 A NPWC version where the wing outline is described by a Cubic Bézier curve.
• Sewing Machine Repair Solving a thread buildup problem.

Plans and updates for the NPWC can be found here or by clicking on the picture of the NPWC to the right. The NPWC is a sparless bridleless single skin soft kite similar to Francis Rogallo's NASA Parawing (NPW).

Enjoy your visit.
