Eichmann Flying Wing Airplanes
« on: October 12, 2016, 06:03:02 am »
Hi,

Mr. Ellis V. Eichmann started to design a flying wing concept in 1937,by created the
Aerobat I,a two-seat monoplane,followed by Type-A & Type-B of 1946,which differed
in have a tricycle landing gear.

The Aerobat II was a two place side-by-side airplane with a wing and empennage almost
identical to Aerobat I; it flew a limited but unknown number of times,Witnesses reported
to the IIC that the pilot/builder/designer completed Aerobat III in July of 1986 and was
issued a Special Airworthiness Certificate in the Experimental Category.This airplane differed
 from its predecessors in that the engine was moved to the rear of the airplane (pusher type)
and the wing was redesigned.

Hesham, the titles for the two drawings are reversed - the Culver is the airframe to the right and the Eichmann to the left.  The publication screwed that one up.

Enjoy the Day!  Mark

Dear Hesham,
The conventional airplane - on the right - is the Culver Model V. Model V was made of wood with an 85 hp engine. It cruised at 125 and had a 13,000’ service ceiling. Only 378 were built starting in 1946. Culver went bankrupt, like a dozen other American airplane factories during the late 1940s.

With that parallelogram platform (leading edge parallel with trailing edge) it is almost a diamond wing!
 With a little longer wing root, it would have a square planform! A longer wing root would improve handling in pitch, but not contribute anything to rate of climb.
