A fifty-five horsepower Viale 5-cylinder radial-powered monoplane from Canada circa 1909, constructed by Louis Prosper, possibly of Montreal.
Prosper Monoplane
Pioneers
Prosper, Louis
Possibly of Montreal, Canada, circa 1909, almost nothing is known of Prosper, although he was reported to have assisted in the assembly of the infamous “Scarabée” – a Channel-crossing 50 hp Blériot XI flown by Comte Jacques De Lesseps – at the Montreal aviation meet, Canada’s first airshow, which ran from June 25 until July 5, 1910.
Pröckl & Hasselböck Motorschwingenflieger / Flügelschlagflieger
The Motorschwingenflieger / Flügelschlagflieger designed by Moritz Hasselböck and Wilhelm Pröckl, and apparently worked on for five years in Vienna, was completed about 1908. The construction of the machine reveals that the flapping wings were not only just flapping in a vertical plane. Pröckl & Hasselböck had realized that in this way the ornithopter would only ascend and descend vertically. To achieve forward motion they devised a method to rotate the wings to another angle with the objective to achieve forward motion or in the event of landing, a braking of the speed of descent.
The machine was built to specification by “Automobilfirma Wyner, Huber und Reich” of Vienna. Photos taken on the property of the firm date from July 1908.
Prini-Berthaud 1909 Biplane
The Prini-Berthaud Biplane had two Wright-style pusher propellers, powered by a 3-cylinder water-cooled Anzani. It was an aerodynamically primitive plane, with uncambered wings, and there is no evidence that it ever flew. It was tested at Port-Aviation, France, in July 1909.
Pride 1909 monoplane
The 1909 Pride monoplane designed and built by Christopher Pride in the UK, flew 976 yards before hitting a tree.
Span: 32’8″
Weight allup: 684 lb
Preble-Rekar Airship
A never-completed 250 foot rigid airship, 24 feet in diameter, under construction during 1909-1910 by the Preble-Rekar Airship Company of Portland, Oregon.
Its dimensions were to have been 250 feet in length and 25 feet in diameter. Apparently bankrolled by Oregon investors, the Preble-Rekar Airship Company of C. H. Preble and J. J. Rekar (Rekar of San Francisco, CA), set up shop in Portland. The structure was made of spruce and no nails or bolts were used.
Povokhovschikov 1 monoplane
The 1911 Povokhovschikov 1 monoplane was designed and built by A. A. Povokhovschikov in Russia.
Span: 26’3″
Length: 24’7″
Weight loaded: 628 lb
Speed: 50 mph
Poulain-Orange 1909-1910 monoplane
Gabriel Poulain moved to Berlin in 1909 and started building airplanes. The first design was an Antoinette-inspired machine. He qualified for German licence No. 14 on it in July 1910 at Johannisthal. He later teamed up with Charles Boutard and built a second monoplane with a more powerful 100 hp Argus, before moving back to France in 1911.
Poulain-Orange No.3
Gabriel Poulain, a famous bicycle-racer who held at least one speed record on the track, built this monoplane, his third design, in 1912.
Poulain-Orange No 2 monoplane
The 1911 Poulain-Orange No 2 monoplane was designed and built by Gabriel Poulain.
