Žurovec 1912 monoplane

TerryLeave a comment

This monoplane was built at the home of the Žurovec brothers in the village Harty (German: Lilien) near Petrvald (Groß Peterswald) in 1912. When completed it was exhibited in the village inn of the neighbouring Albrechticky (Klein Olbersdorf).

Afterwards it was tested on the meadows between these villages, where today the airport of Ostrava (Ostrau) is located. But because of the quickly overheating 40 hp Delfosse engine only short flights with heights of no more than 40 metres could be obtained.

It was the first aircraft built and flown in Moravia (Mähren). Josef Žurovec was the driving person behind this design. He later should have joined the k.u.k. Fliegertruppe, but not much is known of him. Better known is his elder brother Vilém Žurovec, for his work with Petroczy and Kárman and the developement of the PKZ-1 and PKZ-2 helicopters.

Plane-Mobile NX30031

The 1947 Plane-Mobile built by Daniel R Zuck and Stanley D Whitaker was a roadable airplane with a floating, or pivotal, wing, free to change its angle of attack according to the vagaries of the air currents. There were no rudders or elevators in the tail, instead the wings had “ailerators,” a combination of ailerons and elevators.

Registered NX30031, it reportedly suffered a severe ground loop during a test flight.

They have a span of 20 ft. and a chord of 6 ft., while the total lifting surface of the machine is 130 sq. ft., and the elevator has an area of 21.5 sq. ft.

Zornes 1912 Headless pusher

Charles A. Zornes seems to have started aircraft construction in Walla Walla, Washington, USA, in 1909. After they trained at the Benoist Aviation school in St. Louis, he and Johnny Ludwig together with some associates set up a company in 1912 in Pasco, Washington to manufacture aeroplanes. He also ran a flying school there, with the 1912 headless pusher and at least two others. Zornes crashed on April 19 1912, with injuries that did not seem to be life threatening. He appears in some lists of aviation casualties after the accident, but it appears he might have survived and lived until 1954.
