Germany Planning Huge Airplanes
For Regular Passenger Service

planes. however, the wings Will De tnlck
enough to contain accommodations Oh
every sort for the passengers.
Prof. Junkers, builder OF the trans
atlantic monoplane Bremen: Dr. n.
RumpIer, builder Of Germany's famous
two-seaters used in the war; DR.. CRU
Itch, technical manager Of the Oerns-~
Lufthansa air lines. and DR.. II. kIams
Of Breslau are the fores1gnted German
aeronauti'al engineers who have STAR
ed the ball rolling toward the big
planes. Each has designed leVlatnan
of the air.
The most radical Of them all Is Prof:
Junkers' creation Of the "J-lOOO,
which Is nothing more than a flying
wing. The elevator, which enables
plane TO go up or down. Is located out
in front Of the single wing, while the
rudders which steer the plane from lett
to right are attached TO the trailing
edge of the wing. In this big creation
Of duralumin and steel are mounted
four engines, each Of 1000 horse
power, and accommodations for 100 pas
sengers. The span Of this wing is 230
feet, and, due to its large size and
everything, notwithstanding all the
girders and braces. The observation
rooms Of the leading edge. or front
part. Of the wing adjoin the living
rooms, which are comfortably furnished
for both day and night flying. Then
there Is a central corridor running the
whole length Of the wing.
The two fuSelages, which also serve
as the landing hulls, project short
distance out in front and support the
elevator. Prof. Junkers has patented
14fo ~ Oh yrsof fctr mill
sist entirely Of lift-producing parts
the wings-and contain no construc-
ton features which in themselves do
not assist the plane to fly.
DR.. Rumpler's seaplane, however. IS
on the conventional lines Of hull, mono
plane wing and fuselage. Like the
Junkers, it is all-meta1. The wing span
is 3O8 feet and the length. 129 feet.
Ten engines, each delivering 1000
horsepower, are mounted in the wings
and drive "pusher" propellers. The
big ship is supported on the water by
six floats. four Of which are extended
back as fuselages and support the con-
rooms are In the front part Of the wing
and some Of them are large and luxuri-
ously fitted up. Each room has six
seatC and is provided with front
windows and skylights. In order to
deaden the noise Of the engines, there
is a broad corridor between the passen-
ger rooms and the engine room.
The fuel tanks are located In the
pontoons, and the amount of fuel the
plane can carry is sufficient to give Is
hours Of fight. With no head-wind, It
| would be possible to fly 2,735 miles at
| full engine power, but DR.. Rumpler has
be flown without stops as the carrying
of so much fuel would produce excessive
stresses.
The Rumpler plane can carry 100
passengers. 1928 pounds Of baggage,
freight and mail and crew of IS. The
total weight Of the ship is 253,53
pounds and the average speed is placed
at 124.27 miles per hour
DR.. Grulich's seaplane Is a twin hull,
high-wing monopIane and has ten
1,000-horsepower engines in the lead
ing edge Of the wing. The monoplane
wing has a span Of BIT feet and a
length Of 1877 feet and the passengers, as
IN the other planes, are accommodated
in luxuriously furnished cabins located
| within the wing
The fourth project. that by Klamt. is
an all-metal cantilever monoplane, with
a 459-foot span and a 197-foot length,
powered by five 3,000-horsepower en-
| gines. Two Of these engines lie in the
| leading edge Of the wing and drive
| tractor propellers, while the other three
are installed in the trailing edge and
| drive pusher propellers. The $50 pas
sengers are accommodated in the front
and middle thirds of the wing along
the larger portion Of its span and
passageway connects the cabin groups
Klamt estimates the cost Of such
seaplane at about $1,000. 900. and two
years would be the minimum time In
which it could be built. The designer
estimates speed Of about l65 miles per
hour for the plane.
