Stampa la paginaOtto Lilienthal (May 23, 1848 – August 10, 1896) was a German pioneer of human aviation who
was the first person to make well-documented, repeated, successful gliding flights. He followed an
experimental approach established earlier by Sir George Cayley.
In 1867 he began his experiments on the force of air in earnest, interrupted when he volunteered
to serve in the Franco-Prussian War. Lilienthal made his flights from an artificial hill he built near
Berlin and from natural hills, especially in the Rhinow region. Working in conjunction with his
brother Gustav, he made over 2,000 flights in gliders of his design starting in 1891 with his first glider
version, the Derwitzer, until his death in a gliding crash in 1896.
Lilienthal did research in accurately describing the flight of birds, especially storks, and used
polar diagrams for describing the aerodynamics of their wings. He made many experiments in an
attempt to gather reliable aeronautical data. His gliders were controlled by changing the centre of
gravity by shifting his body, much like modern hang gliders. However they were difficult to
manoeuvre and had a tendency to pitch down, from which it was difficult to recover.
He made over 2000 flights, but during a flight on 9 August 1896, Lilienthal's glider stalled and he
fell from a height of 17 m (56 ft), breaking his spine. He died in Berlin the following day, saying
"Kleine Opfer müssen gebracht werden!" ("Small sacrifices must be made!"). He was buried at
Lankwitz Cemetery in Berlin.

This Historic Wings kit is made from etched brass for the structure. The flying surfaces
can be covered with the Litespan film supplied, although many modellers may prefer to leave
the structure uncovered to show the details.
Brass components can be soldered together, or joined with Cyanoacrylate Adhesive (CA or
SuperGlue) or 5-minute epoxy.
To remove parts from the etched fret, you can use a pair of side cutters, or put the fret on a
ceramic tile or similar hard flat surface, and press down on each attaching tab with a sharp knife.
If you use the 'knife & tile' option, put the attaching tab with the half-etched side of the tab face
down. Whichever method is used, it may necessary to remove the burr of the attachment tab
with a needle file afterwards.
CAUTION - MAKE SURE THE ORIENTATION OF THE WING IS CORRECT
BEFORE YOU TWIST EACH RIB.
The wings are etched with integral ribs. Hold the leading or trailing edge in a vice or clamp,
and then hold each rib in turn with a pair of fine flat-nosed pliers, and twist that rib through 90
degrees, while simultaneously holding the other end with another pair of pliers.
