Abstract:

Autogyros can become an alternative for the use of rotorcrafts in various fields of life, including agroforestry. They have better economic performance than helicopters, owing to, among other things, the presence of a bearing rotor. Most autogyros also have other advantages in terms of no need for the compliance with stringent regulatory regulations – with respect to new constructions, lower combustion, noise and emissions of toxic elements. The cover of the bearing rotor head is an important element of rotorcrafts, which demonstrates that aerodynamics plays an important role in aerodynamic designs. Therefore, in this article, air flow model testing is carried out for two types of the bearing rotor blades of an autogyro with and without a cover using the ANSYS Fluent program. An aerodynamic drag analysis was also performed.

Abstract:

Tonight we commemorate the achievements of Juan de la Cierva, the great pioneer of rotary aviation. His development of the autogyro stimulated the development of the early rotor theories and paved the way for the modern helicopter. In turning the autogyro into a practical aircraft, Cierva proved to be an innovator prepared to take an unconventional approach. He was at the same time pragmatic in that he really wanted to build a helicopter but realised that the required technology was not yet mature, and settled on the autogyro as representing what was an achievable concept. His concept was thus unconventional, dramatic and achievable — an admirable combination. However, in his first attempts to fly an autogyro he rapidly came up against the problem that faces all rotory wing designers — which is that the advancing blade has a much greater lifting potential than the retreating blade, due to the difference in dynamic head. This led him to introduce the flapping hinge that allowed the rotor to achieve roll balance as well as providing the backward tilt of the rotor that is necessary for autorotation. Having made this step forward, he realised that the introduction of blade camber would allow the retreating blade to achieve higher angles of incidence before stalling, but in so doing he built in a potentially dangerous control characteristic.

Abstract:

El artículo expone la autogira como una experiencia académica y una buena actividad en las cinco asignaturas que tienen dos prácticas de laboratorio en la Cátedra de Tecnología Agroindustrial. La autogira es una actividad que se le ofrece al estudiante como alternativa, y que es evaluada de manera sumativa; además, se pretende que se convierta en una motivación más para determinar su afinidad con las diferentes áreas de las tecnologías en las que trabajará en su futuro como profesional. Anteriormente, para llevar a cabo la gira de campo, era necesario coincidir en día (sábado) y hora (mañana) todos los estudiantes del país. Por lo tanto, se propuso la autogira, por medio de la cual los estudiantes de forma independiente pudieran desplazarse a industrias del campo, según asignatura, supermercados y mercados, entre otros lugares. Esta buena práctica tiene la flexibilidad y autorregulación de tiempo y espacio para el estudiante y sin costo extra. Asimismo, con ésta los estudiantes conocen el medio laboral, los equipos, la materia prima, el procesamiento, al igual que interiorizar las Buenas Prácticas de Manufactura (BPM), y relacionar la teoría y los contenidos en contexto. Si se pretende incorporar esta buena práctica en asignaturas de otras cátedras, se recomienda incluir una rúbrica y una guía de gira para los estudiantes, así como aportarles posibles lugares de gira y una carta de la Cátedra respectiva para el lugar visitado, como medio de aprobación de la autogira.PILOT PLAN OF INCORPORATION OF AUTOMATICS IN THE EVALUATION MODEL AS GOOD PRACTICE IN SOME OF THE SUBJECTS OF THE AGROINDUSTRIAL TECHNOLOGY CHART, PROGRAM OF AGROINDUSTRIAL ENGINEERING, UNED.AbstractThe article exposes the autogira as an academic experience and a good activity in the five subjects that have two laboratory practices in the Chair of Agroindustrial Technology. The autogira is an activity that is offered to the student as an alternative, and is evaluated summatively; In addition, it is intended to become a further motivation to determine its affinity with the different areas of the technologies in which it will work in its future as a professional. Previously, to carry out the field tour, it was necessary to match in day (Saturday) and time (tomorrow) all the students of the country. Therefore, the autogira was proposed, by means of which the students of independent form could move to industries of the field, according to subject, supermarkets and markets, among other places. This good practice has the flexibility and self-regulation of time and space for the student and at no extra cost. In addition, students are familiar with the work environment, equipment, raw materials, processing, as well as internalize Good Manufacturing Practices (BPM), and relate theory and content in context. If it is intended to incorporate this good practice in subjects of other chairs, it is recommended to include a rubric and a tour guide for students, as well as to provide possible places of tour and a letter of the respective Chair for the place visited, as a means of approval Of the autogira.Keywords: Agro industrial Engineering; good practice; autogira; self-regulation; authentic assessment; academic assessment.

Abstract:

Juan de la Cierva was born in Mosei, Spain nearly 100 years ago on 21 September 1895. At the age of 15 he constructed with two friends, a glider of his own design and contined to show great interest in aviation and aircraft design. He gained an engineering degree and in 1918 built his first tri-motor aeroplane in Spain. His concept was to provide a flying machine having a parachute capability for improved safety in the event of an engine failure and he worked in the direction of the helicopter concept, but concluded that true helicopter flight was not technically feasible with the state of the art at that time. He concentrated therefore on short take-off and landing combining both the fixed wing and the helicopters physical characteristics and called his invention the autogyro. The first successful flight with his autogyro was on January 9th 1923 at Getafe Aerodrome, Madrid. By 1925 development aircraft had achieved reliability and he began demonstrations in France, England and the United States before starting to produce the autogyro in quantity in both England and the United States. It was Juan de la Cierva's main rotor blade design and creation of the articulated rotor system that played such an important role in the first successful helicopter which flew in 1936 and in all subsequent helicopters.

Abstract:

Geo-replication is essential for providing low latency response and quality Internet services. However, designing fast and correct geo-replicated services is challenging due to the complex trade-off between performance and consistency semantics in optimizing the expensive cross-site coordination. State-of-the-art solutions rely on programmers to derive sufficient application-specific invariants and code specifications, which is both time-consuming and error-prone. In this paper, we propose an end-to-end geo-replication deployment framework AUTOGR (AUTOmated Geo-Replication) to free programmers from such label-intensive tasks. AutoGR enables the geo-replication features for non-replicated, serializable applications in an automated way with optimized performance and correct application semantics. Driven by a novel static analyzer RIGI, AUTOGR can extract application invariants by verifying whether their geo-replicated versions obey the serializable semantics of the non-replicated application. RIGI takes application codes as inputs and infers a set of side effects and path conditions possibly leading to consistency violations. RIGI employs the Z3 theorem prover to identify pairs of conflicting side effects and feed them to a geo-replication framework for automated across-site deployment. We evaluate AUTOGR by transforming four serializable and originally non-replicated DB-compliant applications to geo-replicated ones across 3 sites. Compared with state-of-the-art human-intervention-free automated approaches (e.g., strong consistency), AUTOGR reduces up to 61.8% latency and achieves up to 2.12X higher peak throughput. Compared with state-of-the-art approaches relying on a manual analysis (e.g., PoR), AUTOGR can quickly enable the geo-replication feature with zero human intervention while offering similarly low latency and high throughput.

Abstract:

Despite current research advances in aircraft dynamics and increased interest in the slowed rotor concept for high-speed compound helicopters, the stability of autogyro rotors remains partially understood, particularly at lightly loaded conditions and high advance ratios. In autorotation, the periodic behavior of a rotor blade is a complex nonlinear phenomenon, further complicated by the fact that the rotor speed is not held constant. The aim of the analysis presented in this article is to investigate the underlying mechanisms that can lead to rotation-flap blade instability at high advance ratios for a teetering autorotating rotor. The stability analysis was conducted via wind tunnel tests of a scaled autogyro model combined with numerical continuation and bifurcation analysis. The investigation assessed the effect of varying the flow speed, blade pitch angle, and rotor shaft tilt relative to the flow on the rotor performance and blade stability. The results revealed that rotor instability in autorotation is associated with the existence of fold bifurcations, which bound the control-input and design parameter space within which the rotor can autorotate. This instability occurs at a lightly loaded condition and at advance ratios close to 1 for the scaled model. Finally, it was also revealed that the rotor inability to autorotate was driven by blade stall.

Abstract:

The paper presents the results of mechanical properties testing of thin sheet metal of INCONEL 625 and 718 alloys. These studies are a continuation of experience in the preparation of the technological characteristics of metal strips plasticity necessary for carrying out numerical simulations [1]. In order to process sheets now become necessary to design the process using software such as thermo-mechanical simulation e.g. Eta/DYNAFORM. On the road of numerical simulation are sought optimal conditions for processing sheets. It brings reducing the cost of industrial tests. However, becomes strictly necessary characteristics of mechanical and technological properties describing the characteristics of the charges for forming. Here the problem is solved if we forming limit curves (FLCs) designated and technological tests conducted. Using the FLCs is comprehensively defined stamping sheet metal press formability and technological tests allow the mapping of the actual operating conditions selected stamping operations. In the presented study used modern digital analyzer AutoGrid of local deformations and the method of image analysis of deformed mesh subdivision. The use of mesh analyzer and vision systems method significantly speeds up the possibility of producing FLCs. Also measurement accuracy is very high. Selected Inconel alloys are evaluated quantitatively and qualitatively by preparing their properties characterization. The acquired data entered into the database material properties of sheet metal and used in the numerical simulation of stamping process of Inconel 625 cone drawpiece. The legitimacy of the use of modern strain analyzer AutoGrid has been confirmed.

Abstract:

Researchers at the Georgia Institute of Technology have developed technologies to lower maintenance costs for the Navy and to automate more tasks at the factory. The scope of the institute’s engineering research has also grown from its origins in textiles, ceramics, and early helicopter—or autogyro—design. Today, student and faculty researchers in Georgia Tech’s Logistics and Maintenance Applied Research Center—LandMARC—are using the latest information technology to reduce the maintenance and logistics costs for aircraft, I transit buses, and emergency vehicles. The first project undertaken by LandMARC is expected to reduce the cost of maintaining the US Navy’s aging fleet of Lockheed Martin P-3 Orion anti-submarine aircraft by more than $1 million per year. Georgia Tech and Navy personnel are concentrating on improving the diagnostic techniques for the Orion’s engine-driven compressor because it is the airplane’s single most costly repair item. The compressor supplies air to several key aircraft systems, including internal pressurization, engine start, and air conditioning.

Abstract:

Des mouvements sociaux partout sur la planète se révoltent contre la démocratie libérale et le capitalisme tout en expérimentant des manières d’être, de penser et de faire basées sur l’autonomie, le respect de la diversité et l’aide mutuelle. Dans cet article, les pratiques politiques, culturelles et économiques du Centre social autogéré de Pointe-Saint-Charles déployées durant la lutte pour l’appropriation collective du Bâtiment 7 sont examinées à l’aune du concept d’autonomie collective. En rendant visibles ces pratiques subversives, l’analyse permet de saisir la portée révolutionnaire de cette initiative libertaire située en marge de l’économie sociale au Québec.

Abstract:

Nous proposons de présenter dans cet article une partie des résultats de la recherche que nous avons effectuée au sein du Lycée Autogéré de Paris (LAP). Nos observations sont centrées sur le fonctionnement de ce lycée et ses incidences sur le rapport des élèves à l'école et aux disciplines scolaires. Nous avons été amenée à proposer le concept de Travail d'Institutionnalisation (TDI) pour désigner la pratique d'autogestion au LAP qui consiste en un double travail: d'une part, sur les normes internes du lycée et, d'autre part, sur ses rapports aux institutions qui le traversent. Comment ce concept interroge-t-il la "violence" qui surgirait dans l'institution éducative et les pratiques des professionnels censées y répondre?

Abstract:

Die beschriebene Zeichnung befindet sich heute im Stammbuch der ältesten Tochter der Familie, Emily Moscheles, das zur Musiksammlung der Staatsbibliothek zu Berlin gehört (D-B Mus. Ms. Autogr. S 10). Sie zeigt den wohl originellsten Eintrag im Stammbuch und ist mit Widmung und Datum (23.6.1844) zweifelsfrei Felix Mendelssohn Bartholdy zuzuschreiben. Die filigrane Bleistiftzeichnung illustriert auf kleinster Fläche mit bestechendem Charme und einigem Witz die Geschichte des musikalischen Heranwachsens der Emily Moscheles. bms online (Cornelia Schöntube)
