Design and development

After flying his glider in Binţinţi, Aurel Vlaicu moved to the Kingdom of Romania.

On November 1, 1909, he began the construction of his first powered airplane, the A. Vlaicu Nr. I at the Army Arsenal in Bucharest. The Romanian Ministry of War provided an initial grant of 2000 lei, and Minister of Public Education was paying Vlaicu a 300 lei monthly stipend.

The A. Vlaicu Nr. I flew for the first time on June 17, 1910, over Cotroceni airfield.[1]

Military Commission Report [2]

Below are the minutes after aerial demonstrations held by Aurel Vlaicu in August 1910 before a military commission :

Underwriters assisting in day August 13, 1910, from flights performed by the airplane or engineer Vlaicu I agree to the following conclusions to be made to the Ministry of War, which subsidizes this engineer .

  1. flights performed were two in number, of the same kind and go, the former being slower than the second. Both were executed at Cotroceni 6 pm and 6 and ¼ , a calm atmosphere.

    Turning first he made smoothly traversing a distance of about 40 m, after which the unit was raised with all wheels at once, taking up diagonally from the corner of North hangar polygon infantry, until it reached a height of 40 m . Aviator long welcomed chapel in his right hand and went on the height at line forts, bypassing then north to the East where he bypassed followed right into the hangar where it landed among the public traversing about 20 m in all this time about 10 minutes, about 14 kilometers to go, the machine running 27 horsepower and so propellers spinning slowly, because they could see the blades . There was not the slightest hesitation, pitching or rocking.

    On descent, the pilot was applauded and embraced by acquaintances, friends and protectors . He said he is very pleased with the device, but the engine lubricant spread, and dirty clothes pilot, which will be remedied by the adoption of a curtain.

    2nd run on the same road traveled, but rising by 14–15 m to go on the ground and climb up to about 60 m landing was made calm and safe, all in the midst of assistance. Aviator always greet passes to show that he can lead the unit with one hand. Made during the 15 km in 9 minutes (about 100 km. Per hour), with 37 hp (machine can produce 50 horsepower).
  2. It is our opinion that these flights are probably the best way to engineer Vlaicu is true that we have little to compete with the first appliance or apparatus known. This opinion is based on the consideration that an appear below the experienced author would not have run so successful flights as pilot practice is very limited and did not fly away itself until today, the timidity natural accident caused by his clumsiness due to steering. Merit aviator but Vlaicu is that without pilot school and without having to be flown for the first time managed to run flights to the most famous aviators, without having their calm temperament. This proves that the device or helped much success through the qualities of stability and simplicity of maneuvering . But believe that this airplane can be a valuable reconnaissance unit, meaning very good military and we believe that the War Department to continue to patronize needful final realization, and to enter into negotiations with the author for to ensure the right building . The above findings are based solely on the good success of these flights, but as before they are convinced of the good qualities of the airplane, which I argued against criticism that it has been exaggerated.
  3. In summary the committee suggests the following:
    1. Continue to proving this model, the assistance of an experienced military commission composed of officers;
    2. Make a deal with the pilot in order to ensure ownership of this device Ministry;
    3. to construct a final model with actual engine for which to predict and agree to the amount of 18,000 lei (new engine);
    4. A fund provided a budget of at least 100,000 lei for the construction of at least part of it required military airplanes;
    5. To be established at Arsenal a special section for building airplanes, under the leadership of engineer Vlaicu, this section being with automotive repair, everywhere under Mr. Vlaicu, for which we suggest a monthly salary of at least 600 lei.

Arms industry in Romania

Before 1989, Romania was among the top ten arms exporters in the world, however its arms industry declined considerably during the 1990s. Exports fell from roughly $1 billion before 1989 to about $43 million in 2006, and the number of employees also fell from 220,000 in 1990 to 20,000 in 2009. Sales to the Romanian Armed Forces have plunged after Romania's accession to NATO in 2004, as factories continue to produce Warsaw Pact-caliber weapons and ammunition, which are incompatible with their Western counterparts. There have also been criticisms related to the quality of Romania's military products, due to the obsolescence of factory equipment and production methods. The Cugir weapons plant, for example, still uses some machinery dated from 1890.As of 2009, sales are roughly evenly divided between the Romanian state and foreign customers such as European Union and Arab countries such as Egypt, Algeria and Iraq. Other countries which have shown interest in Romanian equipment include Afghanistan, Israel, Switzerland, the United States, the United Arab Emirates, India, Georgia and a slew of African countries. There have been some signs of slight recovery, with exports reaching €141 million in 2009. However, the arms industry in Romania still lags behind neighboring countries such as Ukraine, Bulgaria and Serbia.In recent years, the Romanian government has called, unsuccessfully, for the lifting of the European Union arms embargo on the People's Republic of China.

Aurel Vlaicu

Aurel Vlaicu (Romanian pronunciation: [a.uˈrel ˈvlajku] (listen); November 19, 1882 – September 13, 1913) was a Romanian engineer, inventor, airplane constructor and early pilot.

Gnome Omega

The Gnome 7 Omega (commonly called the Gnome 50 hp) is a French seven-cylinder, air-cooled aero engine produced by Gnome et Rhône. It was shown at the Paris Aero Salon held in December 1908 and was first flown in 1909. It was the world's first aviation rotary engine produced in quantity. Its introduction revolutionized the aviation industry and it was used by many early aircraft. It produced 50 horsepower (37 kW) from its capacity of 8 litres (488 cubic inches). A Gnome Omega engine powers the 1912 Blackburn Monoplane, owned and operated by the Shuttleworth Collection, the oldest known airworthy British-designed aeroplane worldwide. A two-row version of the same engine was also produced, known as the Gnome 14 Omega-Omega or Gnome 100 hp. The prototype Omega engine still exists, and is on display at the United States' National Air and Space Museum.
