In 1884, Charles Renard and Arthur C. Krebs, inventors and military
officers in the French Army Corps of Engineers, built an elongated balloon,
La France, which was a vast improvement over earlier models. La France
was the first airship that could return to its starting point in a light
wind. It was 165 feet (50.3 meters) long, its maximum diameter was 27
feet (8.2 meters), and it had a capacity of 66,000 cubic feet (1,869 cubic
meters). Like the Tissandiers' airship, an electric, battery-powered motor
propelled La France, but this one produced 7.5 horsepower (5.6 kilowatts).
This motor was later replaced with one that produced 8.5 horsepower (6.3
kilowatts).
A long and slender car consisting of a silk-covered bamboo framework lined
with canvas hung below the balloon. The car, which was 108 feet long (33
meters), 4.5 feet (1.4 meters) wide, and 6 feet (1.8 meters) deep, housed
the lightweight batteries and the motor. The motor drove a four-bladed
wooden tractor propeller that was 23 feet (7 meters) in diameter but which
could be inclined upwards when landing to avoid damage to the blades.
Renard also provided a rudder and elevator, balloon nets, a sliding weight
to compensate for any shift in the center of gravity, and a heavy guide
rope to assist in landing.
The first flight of La France took place
on August 9, 1884. Renard and Krebs landed successfully at the parade
ground where they had begun—a flight of only 5 miles (8 kilometers)
and 23 minutes but one where they had been in control throughout. During
1884 and 1885, La France made seven flights. Although her batteries
limited her flying range, she demonstrated that controlled flight was
possible if the airship had a sufficiently powerful lightweight motor.

A wealthy Brazilian Alberto Santos-Dumont combined the internal combustion
engine and the balloon. Alberto Santos-Dumont was really not an inventor
but he perfected the art of flying an airship.

The French were designing airships at a very early time. Here is
a photograph of a design that was submitted in 1852.
