REFERENCES RELATED TO THE DEFINITION OF THE STATUTE OF AERONAUTICAL STAFF IN THE PIONEERING PERIOD OF THE ROMANIAN MILITARY AERONAUTICS

The establishment of the Military Aviation 110 years ago, a historical event with reference to the audacious flight made by the engineer Aurel Vlaicu, on the Cotroceni land, with the Vlaicu airplane no. 1 on June the 17th, 1910, the founding of the first Civil Pilot Schools and, later on, of the first Military Flight Training School, specialized aeronautical institutions that will initiate the training of military pilots, represents the starting point that will generate major debates in the leadership and political factors of the Armed Forces, regarding the theoretical and practical methods for the development of this new reality at the beginning of the twentieth century, the selection of the human resource excellently trained and motivated to carry out fearlessly and courageously dangerous activities in the field of air weapons, but also the taking of some measures to regulate the status, the obligations and rights of the aeronautical personnel, aspects that will find their solution by developing innovative legal instruments, adapted to the requirements of the times, which will decisively influence modern developments in the fundamental area of Air Law.

WIND SHEAR ASSOCIATED WITH MEDITERRANEAN CYCLONES ACTIVITY AND THE IMPACT ON FLIGHT SAFETY DURING WINTER OPERATIONS AT HENRI COANDA OTOPENI AND AUREL VLAICU BANEASA AIRPORTS

The regulated airspace in which aircraft flights take place is part of the Earth's atmosphere. At the same time, the same airspace is the seat of meteorological process and phenomena that have no borders and whose activity is not regulated, but whose evolution in time and behavior is governed by their own laws. This study presents, in a descriptive manner, low level dangerous weather conditions associated with wind shear also called the invisible killer. The phenomenon can occur locally, extremely rarely (3-4 times per year) during winter operations, mainly in January, under the activity of Mediterranean cyclones and its uniqueness consists in duration and intensity. To highlight the impact on flight safety in winter operations, especially in the current context of global warming, the reference and analysis periods applicable to this study are indissolubly reduced to days and minutes. When we talk about flight safety, the immediate application of corrective actions by pilots, the reference period is indissolubly reduced to seconds, those seconds that can make the difference between life and death

ELECTRIC GENERATOR POWERED BY A GYROSCOPIC SYSTEM - A THEORETICAL APPROACH

The development of our society now depends on electrical energy and the demand for electrical power increases yearly. Due to the vast amount of carbon dioxide released in the atmosphere by conventional power plants and the negative influence on the climate, new ways of producing electricity must be developed. A gyroscope consists of a spinning flywheel of mass m mounted in a suspension frame that allows the flywheel’s axle to point in any direction. In this analysis, one end of the axle is supported by a pylon situated at a distance R from the center of mass of the spinning flywheel. In order to generate electrical energy at this low speed, the same approach should be used as in wind power electrical generators. In this case, the wind and propeller are substituted by a gyroscopic system and gravitational attraction. Based on the conservation of angular momentum, the gravitational attraction can be used to create a precession strong enough to provide the energy and torque necessary to activate an electric generator similar to those in wind power generators. Instead of recovering the energy from this kinetic energy, we can use the precession rotation created by gravitational attraction to create the necessary kinetic energy.

AERODYNAMIC ANALYSIS OF THE CLARK YH AIRFOIL

The analysis of the performance of aerodynamic airfoils leads to optimized approaches regarding the pre-design of fixed and rotating lifting surfaces, with implications on the global characteristics and performances of aircraft. The 2D aerodynamics of the airfoils provides indications on the aeromechanical behavior of the selected geometric elements, which may come as constructive solutions depending on the typology of the missions and the initial requirements of the project. The article provides a scrutiny of and certain educational perspectives on the Clark YH profile analysis, using freeware tools (Javafoil, Profiles and XFLR5).

MODERNIZATION OF AIR FORCE EDUCATION – ‘SYSTEMS FOR AERIAL SURVEILLANCE AND SECURITY’ PROJECT

The current paper presents an analysis of the ‘Systems for Aerial Surveillance and Security’ (SASS) project, carried out under the aegis of the European Union's Erasmus + [4] programme conducted by “Henri Coandă” Air Force Academy (AFAHC) in collaboration with partners from Poland and Bulgaria. The project aimed to initiate collaboration between the military universities of the European Union in order to establish common competences that the graduates in the field of aviation will acquire upon the completion of their education. One of the reasons for the development of this project was the need to modernize the education in the AFAHC and update the curricula in accordance with the new technologies equipping the military systems and with the modern teaching / learning methods in the civilian higher education. The running of the project and its finalization led to the design of an education curriculum of the Life-long learning type and an e-learning platform. The analysis of the project by means of various satisfaction questionnaires, applied following certain stages of the project, revealed controversial results.

COMMUNICATIVE TASKS IN TEACHING MILITARY ENGLISH

Teaching English through genuine interaction in the target language has represented the trademark of communicative language learning, applied in most classrooms around the world. This approach has generated a shift from the perception of language as a system to the focus on more contextual and meaning-related features of language use. Such aspects are in perfect accordance with the needs of military professionals who use English in specific situations. This study explores some of the possibilities of applying the principles of this efficient approach in learning military English with classes of all levels.

OPERATIONAL MEDICINE - AN IMPORTANT BRANCH OF ROMANIAN MILITARY MEDICINE IN THE CONTEXT OF THE EVOLUTION OF ARMED CONFLICTS

Operational medicine is a concept born from the necessity to adapt medicine to the new progressions in the evolution of conflicts. Taking into account the fact that the forces involved in current conflicts are aware of the new dimensions of warfare, it has also becomenecessary to reconfigure the medical services provided in an operations theatre or in a real battlefield. Therefore, the tacticians, doctors and other American specialists have penciled operational medicine as a sub-branch of military medicine and,respectively, classified itaccording to the type of conflict in which it is engaged, but also according to the military unit it serves. A careful analysis of this concept in its evolution clearly demonstrates that operational medicine has been welcomed by all the parties involved, as the concept was quickly understood and implemented as such, progressively by NATO member states followed by others. Sprung fromnecessity and emerging as a characteristic of an extremely vast field (that of national and globalsecurity),employing dedicated and highly trained people, operational medicine always proves its effectiveness, achieving the best results by saving human lives.
