Flugan was an early aeroplane

Fixed-wing aircraft

A fixed-wing aircraft is an aircraft capable of flight using wings that generate lift due to the vehicle's forward airspeed. Fixed-wing aircraft are distinct from rotary-wing aircraft in which wings rotate about a fixed mast and ornithopters in which lift is generated by flapping wings.A powered...

. Construction started in 1897 and he kept working on it until 1922. The craft only managed a few short jumps and Nyberg was often ridiculed, however several of his innovations are still in use. He was the first to test his design in a wind tunnel

A hangar is a closed structure to hold aircraft or spacecraft in protective storage. Most hangars are built of metal, but other materials such as wood and concrete are also sometimes used...

. The reasons for failure include poor wing and propeller design and, allegedly, that he was afraid of heights.

The Flugan had a wingspan of 5 meters, and the surface area of the wings was 13 m². It was powered by a steam engine

Steam engine

A steam engine is a heat engine that performs mechanical work using steam as its working fluid.Steam engines are external combustion engines, where the working fluid is separate from the combustion products. Non-combustion heat sources such as solar power, nuclear power or geothermal energy may be...

 heated by four blowtorches and it produced 10 hp

Horsepower

Horsepower is the name of several units of measurement of power. The most common definitions equal between 735.5 and 750 watts.Horsepower was originally defined to compare the output of steam engines with the power of draft horses in continuous operation. The unit was widely adopted to measure the...

(7 kW) at 2000 rpm. The power-to-weight ratio was actually better than the Wright engine. The total weight of the plane was 80 kg. The weight of the engine was 18 kg.
