Romanian Lesser Known Airplanes and Designers

[Apophenia]

There was also Paulat Hydro-Aero Duplex Monoplane ?.

The Hidro-Aero Duplex Monoplan was Ion Paulat's original 'hydroplane' design. It was devised in 1908 while Paulat was chief mechanic aboard the Romanian cargo steamer SS Turnu Severin. To test his theories, Paulat constructed a crude wind tunnel on the deck of the ship. The 'Duplex' part refers to the monoplane's twin engines.

Predicted performance was indifferent and construction complex. So design emphasis shifted to a smaller, lighter, single-engined biplane. The Romanian Ministerul de Război (War Ministry) refused to fund the project. But, eventually, shipyard owner Gheorghe Fernic assisted with financing and the Hidro-Aero Biplan flew in November 1911.

The Hidro-Aero Biplan would be written off in an airshow accident on 06 June 1912. Repairs were never attempted because Ion Paulat had been injured in the crash and was later called up for military service.

Many thanks to you my dear Apophenia,

and there was also another Paulat Hydro-Aero Monoplane (not Duplex).

Unknown to me. Perhaps your non-Duplex variant Hidro-Aero Monoplan was a design step on the way to the Hidro-Aero Biplan?

Hi,

also Mr. Victor Ion Popa designed an aircraft before 1917 ?.

Interesting. Victor Ion Popa (an infantry officer during WW1) is today known as a playwright and writer.

Popa's 1939 romanticized biography of pioneer pilot Aurel Vlaicu - Maistoraşul Aurel, ucenicul lui Dumnezeu (Master Aurel, God's Apprentice) - was not very well received. But in his better-regarded 1936 novel - Sfârlează cu fofează (Spinner with Propeller) - a fictional airplane (the 'Lăstun' or 'Martin') is constructed and flown by his characters.

Hi,

Mr. Alexan Tandargian designed a flying wing before 1917 ?.

Mr. Alexan Tandargian designed a flying wing before 1917 ?.

Craiova-based Alexan Tandargian also patented a vectoring-thrust concept in 1909 (Brevetul de invenţie nr. 1663/1909).

His project includes innovative concepts, from the design of the airframe to the engine arrangement. The novelty was in the vertical handling of the aircraft. This would be achieved by vectoring propeller thrust - the vertical axis of the rear propeller being adjustable, thus changing the angle of tractive force.

Attached is an image from that page (and patent) with an attempt to correct for distortion.

Hi,

there were also two Lenticular Aerodyne concepts of 1932 and 1935,may
from Coanda ?.

Who heard about a glider,designed by Mr. Petre Andrianov ?.

 

[fortrena]

From the looks of it, Petre Andrianov was an engineer who, in 1908, designed, built and tested a glider of his own design near the city of Galati.
