A human-powered aircraft (HPA) is an aircraft belonging to the class of vehicles known as human-powered transport.

Human-powered aircraft have been successfully flown over considerable distances. However, they are still primarily constructed as engineering challenges rather than for any kind of recreational or utilitarian purpose.

Engelbert Zaschka (September 1, 1895 in Freiburg im Breisgau, Germany – June 26, 1955 in Freiburg im Breisgau, Germany) was a German chief engineer, chief designer and inventor. Zaschka is one of the first German helicopter pioneers and he is a pioneer of flying with muscle power and the folding car. Zaschka devoted himself primarily to aviation and automotive topics, but his work was not limited to them.

Engelbert Zaschka is a prominent representative of the rotary aircraft, a class of rotorcraft systems - according to Zaschka. In 1928/1929 Zaschka developed and constructed the first collapsible and foldable small car (folding car) and in 1934 an early muscle-powered airplane.
