George E-mail: [email protected] (Gogu) Constantinescu (4.Oct.1881 - December 11, 1965) was a Romanian scientist and engineer, often considered to be one of the most important Romanian engineers. He was responsible for creating a new field of mechanics, called "sonicity," which describes the transmission of energy through vibrations in fluid or solid bodies. He applied the new theory to numerous inventions: sonic, sonic, sonic and others. Among other achievements, there is also a pulling device among the propeller blades regardless of its speed and the first automatic gearshift. He has actively participated in the construction of English aircraft, the Bristol type, while he lived in England. Henri Marie Coanda (June 7, 1886 - November 25, 1972) was an Academician and Romanian engineer, aviation pioneer, physicist, inventor, inventor of the reaction engine and discoverer of the effect that bears his name. 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 doctor Gustave Danet. Traian Vuia (August 17, 1872 - September 3, 1950) was a Romanian inventor and an aviation pioneer who designed, built and tested his own planes, which at the time were among the first heavier aircraft than the air. On March 18, 1906, he made his first self- propelled flight (without catapults or other exterior means) with a heavier device than the air. In his first flight he managed to float about 12 m (40 feet) at Montesson in France on March 18, 1906. This was the first "certified" flight with the take-off and landing of the aircraft (unassisted from the outside), made with a monoplane aircraft powered by a wheelchair. Performing a mechanical flight with a heavier machine than the air was a fascination at the end of the past and the beginning of our age. Thousands of fools tried to accomplish it, while the "balloons," who at the end of the eighteenth century had managed to rise in the balloons of the balloons, were smiling with superiority, convinced that the future is theirs, those with more aerial vehicles light than air.

Relly Victoria Petrescu et al . / Journal of Aircraft and Spacecraft Technology 2018, Volume 2: 1.18 DOI: 10.3844/jastsp.2018.1.18 Introduction It is said that "the Romanian is born poet". And so it is, but we could say rather that "the Romanian is born and an engineer", having deeply embedded himself, the vocation of the builder, the innovator, the inventor. The great cathedrals, the beautiful monasteries built, or even the churches and churches (built or wooden) clearly show this vocation. After centuries, the "Voroneţ blue" still retains its vivid colors, even on the outer walls, beaten by rain, snow and wind. Suveica, the loom of war, the potter's wheel, the water and wind mills, the musical instruments, the wells or the fountains, the agricultural tools, the traditional Romanian houses with cerdac and porch, are only some proofs of the folk craftsmanship (engineering) over time. Ever since the beginnings of civilization on today's territory of Romania, the inhabitants of these lands have been pioneers in creation and have thought of things that others have found much later. Apolodor Bridge in Damascus is one of the ancient techniques of Romania. It was built between 102 and 105 AD by Christ of Emperor Trajan, Roman architect and constructor of Greek-Syrian origin, Apolodor (from Damascus) and "united" the Roman Empire with Dacia. The bridge was 1,135 meters long and 18 meters wide and was made of stone masonry with superstructure and oaken parapets. Among the last components were two small viaducts, also executed with stone masonry bolts and at each end of the bridge, above the grate, there was an impressive portal. One foot of this bridge is still preserved today in Drobeta Turnu-Severin (Aversa et al ., 2017a-e; 2016a-o; Berto et al ., 2016a-d; Mirsayar et al ., 2017; Petrescu and Petrescu, 2016a-c; 2013a-d; 2012a-d; 2011a-b; Petrescu, 2016; 2012a-b; 2009; Petrescu and Fig. 1: Traian Vuia's plane.

  • A Nation of Aviation Pioneers
    ICAO TIE-INS By Albert Pelsser Romania - A nation of aviation pioneers At the beginning of the 20th century, Romania was among the few nations in the world which brought essential contributions to aviation and flying because there were people who dedicated their life and work to fulfilling the human desire to fly and developing aviation. Among the most well-known inventors who contributed to the flight development by means of apparatuses heavier than the air, Traian Vuia, Aurel Vlaicu and Henri Coanda played a distinct role. In parallel to the above developments, schools of piloting were established and airships from other countries were purchased, with provision for specially designed workshops for the maintenance and repairing of aircraft. The first school of piloting was initiated by the Romanian lawyer Mihail Cerchez, after his return from Paris in the summer of 1909. It started its activity in the spring of 1910, on the field near Chitila, where the first aerodrome of the Romanian aviation was settled. Once the infrastructure for the construction and repair of the airships had been completed, Mihail Cerchez purchased four aircraft from France: two biplane Farman aircraft that were intended to carrying out the training flights of the future pilots, one Demoiselle aircraft and a Wright aircraft for the ground instruction. Second Lieutenants Ştefan Protopopescu and Gheorghe Negrescu were among the first six military pilots trained. Cerchez also obtained that the Farman aircraft be assembled in his workshops. Chitila’s infrastructure in 1911. Farman IV biplane. Having obtained their Pilot Licences in July 2011, Protopopescu and Negrescu, along with other pilots, participated in military maneuvers on Farmans in the fall of 1911 and carried out a series of raids to popularize aviation among youth and to maintain a high degree of readiness among pilots.

  • 32 ROMANIAN CONTRIBUTIONS in AERONAUTICS Adrian NECULAE
    ROMANIAN CONTRIBUTIONS IN AERONAUTICS Adrian NECULAE West University of Timisoara, ROMANIA A short history of the flight From the earliest days, humans have dreamed of flying and have attempted to achieve it. The dream of flight was inspired by the observation of the birds even from the early times and was illustrated in myths, fiction (fantasy, science fiction and comic book characters) and art. Greek, Roman or Indian mythology have examples of gods who were gifted with flight. Daedalus and Icarus flew through the air, and Icarus died when he flew too close to the sun. Daedalus and Icarus (Greek) Pushpaka Vimana of the Ramayana (Indian) Religions relate stories of chariots that fly through the air and winged angels that join humans with the heavens. Flying creatures that were half human and half beast appear in legends. Birds and fantastic winged creatures pulled boats and other vehicles through the air. Let’s see some relevant examples: 32 From the top left corner: Angel, Pegasus, Dragons, Superman, Santa Claus, Dumbo. My talk is about progress in science, and more specific, about progresses in human fight against gravity. An illustration in art of the idea of what it means the progress in flight is given in the picture below, painted at the end of the 19th Century: The human dream of flight: Utopian flying machines from the 18th Century. The image and the title of this art work express, maybe better than other words, the idea of progress in flight, especially in modern and present history: things that seemed to be pure utopia a century

  • Elie Carafoli at the Romanian Academy
    INCAS BULLETIN No. 2/ 2009 ELIE CARAFOLI AT THE ROMANIAN ACADEMY Acad. Radu VOINEA DOI: 10.13111/2066-8201.2009.1.2.3 Heading towards the Romanian Academy Elie Carafoli was born in Greece, Veria, not far from Thessaloniki. His parents, of Romanian nationality, were at the forefront of those who fought for the defense of their ancestral language/ mother tongue and for social and political rights of the Romanians of the Balkan Peninsula. These Romanians are mentioned in chronicles written about the Fourth Crusade, in which are also shown the regions inhabited by them: United Walachia, Minor Walachia, Upper Walachia. The inhabitants of these lands were called Macedonian - Romanian. After Ali Pasa satrap of Ioannina (Epirus) ruthless persecution which, among other things, burned twice Moscopole town, followed the exodus of Macedonian- Romanian to neighboring countries: Italy, Serbia, Greece, Austria-Hungary, but especially to Romanian countries. In these particularly difficult circumstances, Elie Carafoli attended primary school in the city of Veria, (where he was born), within the Romanian school, then entered the Romanian Commercial School in Thessaloniki, finishing the third grade in 1915, after which, considering that a further training at a high school would be more appropriate for him, in 1915 he enrolled in the fourth grade in Romanian high school in Bitola (Monastir), Serbia. But scarcely had school started when it closed because of the occupation of Serbia by the Central Powers armies, despite bitter resistance of Serb army. Should I leave the academic Elie Carafoli to narrate adventures that followed: "Here I was, the school broken off and separated from family: Romanian country's image suddenly appeared in my mind insistently.

  • Traian Vuia – the Romanian Inventor Who First Flew a Powered Airplane in 1906
    Traian Vuia – the Romanian inventor who first flew a powered airplane in 1906 Liviu FILIMON *Corresponding author Liviu - Avionics and Instruments Services Ltd. 40 Wairere Rd, The Gardens, Auckland 2105, New Zealand [email protected] DOI: 10.13111/2066-8201.2011.3.3.15 Abstract: As observed the beginning of heavier than air devices started with Wright Brothers who flew in 1903 the first catapulted airplane equipped with an engine, similar to present motor gliders. In March 1906 took place the first flight of Vuia’s monoplane using on board installations. Since then a real competition between manufacturers has started to improve their airplanes as they become more efficient. Traian Vuia’s first flights and his beginnings are explained below. Key Words: history of aviation, powered aircraft, first flight, Romanian inventor. 1. INTRODUCTION During the year 1906 Vuia made three major contributions to the world of aviation. Firstly he flew for the first time a vehicle heavier than air using only his on board installations; secondly his airplane was the first to fly with only one propeller and thirdly his airplane was the first single-plane powered aircraft to fly. 2. TRAIAN VUIA’S FLIGHTS Traian Vuia was born on August 17, 1872 in a village known as Surducul Mic in the Timis county of Romania. Since childhood he dreamed to be able to fly a machine invented by himself. He studied only technical problems that he was particularly interested in, the problem of flight being for him the most important one. After graduating the high school in Lugoj (Timis county) he could not finish a school of mechanics due to financial problems, and had to attend and graduate a faculty of law which in those times could provide him with financial support.

Erau aşa-zişii “ piloţi de încercare”. Primii “test piloţi” din IAR au fost: căpitanii aviatori Romeo Popescu, cel cu care am făcut eu botezul aerului,Alexandru Papană, Dumitru Pufi Popescu, iar după moartea lui a devenit pilot şef de încercări inginerul pilot Dudu Alexandru Frim, unul dintre cei mai buni prieteni pe care i-am avut . Dudu Frim continuă zborurile de încercare şi punere la punct ale avioanelor IAR-80, IAR-81, după care execută zborurile în premieră absolută pentru avioanele IAR 47 şi a întreaga serie de bombardiere Savoia Marchetti.

Four of these, with three located in Bucharest, produced over 2000 aircraft, maily for the military use as Romania entered the Second World War. The activity of these factories was undertaken in times when nobody thought about formulating the principles of quality management and the research of the first scientists in quality, Deming, Shewhart and Juran had not yet been accepted or published. The work aims to present the inter-war Romanian aeronautical industry developments regarding the quality management. Key Words: Principles of quality, The General Aviation Reserve, The Aeronautic Arsenal, Astra Arad, SET, IAR, ICAR, Mircea Grossu-Viziru, Ion Grosu, Elie Carafoli, Radu Manicatide, Deming, Shewhart 1.
