APPENDIX "D"
FLYING WING TYPE Arn.CRAFT
1. AERONAUTICAL ENGINEERS in several countries have been engaged for some tlme in the
design, construction, and flight of flying wing type aircraft. The study of flying objects requires,
at least, a brief examination of proposed and existing unconventional aircraft whose configurations,
when seen by the uninitiated, could lead to reports of strange flying devices. A description of
some of. the more significant types by country follows,

2. GERMANY.
At the end of World War II, German aircraft designers had numerous projects
under way concerning tailless air.craft which conceivably could be mistaken for "Fly~g Saucers"
or disc-like objects. It is not clear just what the Soviets are doing in the way of developing
these projects but it is considered that German studies on taflless, delta.-wlng, and related con­
figurations are available to the U .S.S.R.
a. ARADO NIGHT AND BAD WEATHER FIGHT
I.
This is a tailless, low-wing
monop ane w
swept-
g a long, narrow fuselage.

b. ARADO E 581-4. A high-wing tailless single-seater with a single jet unit mounted in the
fuselage.
bi and ruader units are mounted on the wing midway between fuselage and wing tip
at the trailing edge.

29.3 feet
Length
18.4 feet
Power Plant
1 HeS 011 turbo jet unit
Max. Speed (sea level)
Max. Speed (service celling)
c. GOTHA P 60 A.
This was the first of the P 60 series of jet fighters. It ls a flying wing
type ~ot and observer 11e prone, there is no projecting canopy, thus permitting a
particularly clean design. The jet.units are mounted at the rear of the center sect1on1 one above
and one below.

596 miles per hour
d. HEINKEL P 1080. This is a single-seat fighter with a sharply swept-back wing, resembling
a flyi~having a single fin and rudder with no tail plane.
Span
