He was a Romanian-born Istron and called him Nicolae Teslea, a Serb-Croatian citizen, descended from Romanian parents (Macedonian Romanians from Banat, or "Alexandro-Romanians" as they are also said to Romanian citizens of Macedonian ethnicity, or istro-Romanian, the istriotians come from the Croatian area of Serbia, from the Istrian Peninsula, situated in the north of the Adriatic Sea, the area was historically conquered and re-conquered. After first belonging to the Hunters, it passed to the West Roman Empire, was plundered by the Goths and Longobardi, annexed to the French kingdom, subject to the Carinthian dukes, then to Meran, Bavaria, after which he passed by the patriarch of Aquileia and belonged to the Republic of Venice and then passed under the power of the Austro-Hungarian Empire of the Habsburgs, with an interruption in the time of Emperor Napoleon who has been annexing it for a while. After the First World War he came under Italian protection and after World War II it was annexed by Serbia, when Tito, with the support of the Russian Communists, created the Serbian Yugoslav Empire. Several years after the "communist camp" broke down, the Croats returned to the island. Among the istriot communities, there are also the Istro-Romanians coming from Banat, Transylvania and Timoc).Nicolae Teslea, or shortened Nicola Tesla (as it is generally known to Americans where the universal genius Nicola has remained and spent most of his life, making it difficult to pronounce "Teslea"), is considered the inventor of the generator alternating current and uncovered cableless power transmission. It is attributed to the transmission of energy through monophase, biphasic, polyphase alternating currents and transmission of non-wired energy by electromagnetic waves (oscillations) in the industrial alternating currents (102-109 [Hz]) band, overlapping band with radio frequencies (the radio band being even more extensive than that of alternative industrial currents).

A scientist and prolific inventor of electronics and radiotechnika, the discoverer of the spinning magnetic field (simultaneously with the Italian Galileo Ferraris, 1847-1897), Tesla invented both the biphasic and polyphase alternating electric currents and studied the high-frequency current. He built the first two-phase asynchronous motors, the electric generators, the high-frequency electric transformer and so on. In atomic, he researched the atomic nucleus fission, with the help of the high voltage electrostatic generator and was also a pioneer of nuclear power based on nuclear fission reactions. (Einstein was contacted and visited personally by his research in this field). By working permanently in industrial bands, Tesla has inevitably given over radio waves whose frequencies overlap with those of alternating currents.Even though Marconi made the first radio broadcasts over the ocean, a little before Tesla, yet at the basis of his achievements were all the patents and works of Tesla, which Marconi had studied in detail. Tesla is the first and foremost builder of the world's first and largest radio stations. In 1899, Tesla builds a large 200kw radio station in Colorado, conducts wireless telegraphy transmissions over 1,000km and manages to get 12 million volts of volumes to produce the first artificial lightning (lightning).He drives the first unmanned ship by radio, from a distance to a public demonstration on the ocean, in New York.Transmits concentrated energy through long-distance electromagnetic waves, the energy it uses to power remote consumers or remote control.Tesla deals with natural energy, the production of artificial earthquakes based on huge energies using very low frequency waves (Tesla is the first to accurately determine the resonance frequency of our planet), acceleration of nuclear particles to very high energies and targeting them or microwaves concentrated in beam (deadly rays) capable of reaching and destroying a target at a great distance (airplane, rocket, ship, etc.).He proposes to build a defensive shield to defend America, but even the planet, if needed (the current US defense shield of the Earth is a continuation of his work). It imagines, presents and designs wireless audio-video transmissions (but was too early to implement them massively, technologies were a long way from discovering it; the pieces were then lamps and tubes, there were no chips or integrated circuits, not even transistors).We can certainly believe that Tesla is actually the true "Parent of Informatics" (Petrescu, 2016).\Methods and MaterialsHenri Marie Coanda (June 7, 1886 - November 25, 1972)Academician and Romanian engineer, aviation pioneer, physicist, inventor, inventor of the reaction engine and discoverer of the effect that bears his name.The first "Coanda" attested in the village of Strehaia was in 1630, Vldoianu Coanda. From the same source (Strehaia City Hall), we learn that Matei Coanda was the protector of Iancu Jianu, the defensive hood of the orphans.Henri Coanda was born in Bucharest on June 7, 1886, being the second child of a large family (Henri had four brothers and two sisters, a total of seven children). His father was General Constantine Coanda, a former mathematics professor at the National School of Bridges and Highways in Bucharest and former Prime Minister of Romania for a short period of time in 1918. His mother, Aida Danet, was the daughter of French physician Gustave Danet (Petrescu, 2016).Even from childhood, the future engineer and physicist was fascinated by the miracle of the wind, as he will later remember. Henri Coanda was first a pupil of the Petrache Poenaru School in Bucharest, then of St. Sava High School in 1896 where he attended the first three classes, after which, at 13, he was sent by his father who wanted to guide him towards his career Military High School in Iasi, 1899. He graduated high school in 1903, receiving the rank of major sergeant and continuing his studies at the School of Artillery, Genius and Marine Officers in Bucharest.Although many remarkable soldiers were in his family, he considered the military career as mediocre and had the desire to become an engineer. Following the voice of conscience, he left for Germany in 1904-1905 and enrolled at the Royal University - Technische Hochschule Charlottenburg, near Berlin, where he obtained the title of mechanical engineer, then attended university courses in Liège (Belgium) and the School Upper Electricity from Montefiore (Italy), where he obtained his degree in Electrical Engineering Specialist.In 1908 he returned to the country and was an active officer in the 2nd Artillery Regiment. Due to his nature and inventive spirit, who did not agree with military discipline, he sought and obtained approval to leave the army, after which, taking advantage of the reclaimed freedom, took a long journey by car on the Isfahan - Tehran - Tibet route. On his return to France, he enrolled in the Upper Aeronautics and Construction School, newly established in Paris, 1909, whose graduate becomes the next year in 1910 as the head of the first aeronautical engineer's promotion.After completing his studies he worked at the Nice sites, led by the famous engineer Gustav Eiffel.

Considerable research efforts have been put into various solutions that are capable of taking over and launching the second blow. All of these solutions included ships capable of launching anywhere, without the need for an airport or even a launching line, vertical take-off aircraft, missiles, etc. which was more on disk.For VTOL operations, the aircraft was expected to stand upright with long legs, which descended from the backbone (from the ship's axis). The landing would have taken place at a very large angle, making visibility in this very difficult time. A number of other VTOL experiments at that time have attempted various other solutions to this problem, including the rotation of pilots and the cabin, but none proved to be very effective. Another problem with the various VTOL experiments was that the stability of the vessel during floating was rather low, being difficult to achieve (including balancing it especially at low speeds or at stops in the air at a certain height). A solution to this problem would require the traction force to be directed downward to a larger helicopter area (surface) where the ascent is provided by the entire surface of the rotor (main propeller). Most designers have called to stop the air from the engine compressor and drive it through multiple pipes around Custom 1/2 impact wrench manufacturer the ship.Frost's engine design used such a large number of side nozzles for sustainability that it was not easy to build practically.In 1952, the design was quite advanced, so the Canadian defense research council, through a supplementary effort (with a $ 400,000 contract), managed to refinance the project by keeping it alive. By 1953, a Y model layout was completed (figure above). ,
