Edward Lanier's « Paraplane »... and other unnecessary designs

[hesham]

Edward Lanier "Paraplane".

http://www.1000aircraftphotos.com/PRPhotos/LanierParaplane1.htm

The Lanier (father and son) were convinced they had invented the best thing since bread came in slice. In fact they just re-invented Handley Page flaps of 1919... in the 40's.
They were aparently inspired by... ice cream cones inherent stability.
At least they build extremely-odd looking aircrafts that were detailed in Le Fana de l'Aviation 371 (year 2000).
The one below is one of the most "reasonable" designs they come by. Imagine the others. :

Here is an article from LA FANA magazine issue 371,about the Lanier company,I know
it had eight experimental aircraft designs,but it is the first time to know PL-9 and PL-10.

Topic split.

That was far too many documents for the "one-offs" thread, which is supposed to quickly present one type per post (and if more information comes in, a new topic is in order).

From Ailes 10/1949.

From flying magazine 1943-1,

what was this designation for Lanier ?.

Lanier seems to have recognized that conventional airfoils lose laminar flow at about 25 percent Mean Aerodynamic Chord.

We wonder if he was depending upon captive vortex to generate lift (ala. Kasper BKB glider).
