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.

Thanks Hesham!

The cockpit is covered by extensive glazing that allow good visibility in all areas. The tricycle landing gear is retractable. We do not know other details related to “Aerobat”.

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
 
Thanks my dears,

and we can change the title.

Merged with older thread, thank you !
 
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.
 
From Ailes 3/1948,

all Info about Aerobat Type-A.

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.
 
Good Day All -

On our recent Spring Break Road Trip, I came across this aircraft at the Texas Air Museum on Stinson Field in San Antonio, TX. Fascinating to see it in person and the photos of it back in 1942 adds much to the history. You'll note that it is now a retractable gear design whereas it originally had a fixed gear. You'll also noted it has a horizontal stabilizer so calling it a flying wing is a misnomer.

Enjoy the Day! Mark
