HP-14 Glide Polar

[Jay Allardyce]

Does anyone know where I can find the polar for the HP-14?

[Wayne Paul]

Jay,

For the purpose of flight computer, etc I find the Standard Labelle to be very close. I plan to do formal flight test on my '14 next spring and will post the results on my bird's page (http://tinyurl.com/N990-6F) which is part of the Schreder Sailplane Designs website (http://www.soaridaho.com/Schreder)

BTW, are you a member of the hp-gliders Yahoo news group? (http://groups.yahoo.com/hp-gliders)

Paul Bikle reported polar test results for his T-6, which was a
slightly modified HP-14T (T-tail rather than V-tail) in the June 1970
issue of SOARING magazine ("Polars of Eight, page 16).

The new SSA Archive has this issue available for viewing or download.

The article is also on the Schreder Designs website.

In addition to the "T" tail, Bikle made slight modifications to the HP-14 airfoil and extended the wing span of "T-6."

Here is the analysis of the Bikle airfoil.

Opps, I misspoke. The "T-6" wings were shortened from 16.64 meters to 14.93 meters.
