En los últimos años, la proliferación y fácil acceso a los vehículos aéreos no tripulados (uav) ha causado un gran número de incidentes en el mundo. Los gobiernos han aunado esfuerzos para regular y controlar la operación de estos sistemas, al impulsar la creación de soluciones que permitan detectar y mitigar posibles ataques mediante estas plataformas. En el presente artículo se describe el proceso de diseño e implementación de un prototipo de inhibición de uav para las bandas gps (L1 y L2), WiFi 2.4 GHz y WiFi 5.8 GHz. Los resultados de las pruebas realizadas mostraron un alcance de inhibición de 150m con una potencia de transmisión por banda menor a 25 dBm.
近年来,无人机(uav)的扩散和容易获得在世界各地造成了大量事件。政府已经联合起来规范和控制这些系统的运行,推动创建解决方案,允许检测和减轻通过这些平台可能的攻击。本文描述了gps (L1和L2)、WiFi 2.4 GHz和WiFi 5.8 GHz频段无人机抑制原型的设计和实现过程。测试结果表明,抑制范围为150米,每带传输功率小于25 dBm。

Democracia vs crecimiento económico: ¿Quién fue primero, el huevo o la gallina? 民主与经济增长:谁先来,鸡蛋还是母鸡?

It has long been taught that democratic strength is the best remedy to gain economic development. In that sense, the broader the social freedoms, the greater the opportunities for the growth of a nation. However, with the rapid development of the Asian tigers, where democracy might not be the common denominator, this vision of development turned not only toward democratic strength but to the structure of institutions as well. Although democracy could remain as the main ingredient to achieve this longed-for and westernized economic development (Lipset, 1959a, 1959b), it is not necessarily the only variable to determine such progress; rather, is the type of institution what becomes essential in establishing incentives and creating better conditions to achieve a political and economic “take-off” of this kind. Hence, democracy, in the long term, would allow opening the way to development, although not without ignoring the importance of history in each country, which in the end determines singularities for the development of nations.
长期以来,人们一直认为,民主力量是获得经济发展的最佳补救措施。从这个意义上说,社会自由越广泛,一个国家发展的机会就越大。然而,随着亚洲虎的快速发展,民主可能不是共同点,这种发展愿景不仅转向了民主力量,也转向了制度结构。尽管民主仍然是实现这种渴望已久的西方化经济发展的主要因素(Lipset,1959a,1959b),但它不一定是决定这种进步的唯一变量;相反,在建立激励机制和创造更好条件以实现这种政治和经济“起飞”方面,制度类型是至关重要的。因此,从长远来看,民主将为发展开辟道路,尽管并非不忽视历史在每个国家的重要性,而历史最终决定了各国发展的独特性。

This article examines the space segment as part of the structuring process of an aerospace project, starting from the problem of disarticulation of design processes, the omission of operational factors, and unawareness of the behavior of the space segment in orbit. For this purpose, it is necessary to revisit the steps required in the mission design of a space system, the architecture and the constituent subsystems of the generic segment, as well as the useful operational factors for the development of the mission concept. Hence, different representations of the orientation and translation movement of the space segment are presented as a guide for the modeling of low-orbit observation missions. Based on this, two characterizations of design and representation requirements are provided as practical examples —both for the mission design, with the synthesis of mission objectives of a space program, and the representation of the space segment— against the needs of a close proximity mission with in-orbit maneuvering capabilities that may require not one but several coordinated satellites; all this by using the Electromagnetic Formation Flying method (emff).
本文将空间段作为航空航天项目结构过程的一部分,从设计过程的脱节问题、操作因素的遗漏以及对轨道上空间段行为的不了解开始。为此目的,有必要重新审议空间系统的任务设计所需的步骤,一般部分的结构和组成子系统,以及发展任务概念的有用的操作因素。因此,提出了空间段定向和平移运动的不同表示,为低轨观测任务的建模提供了指导。在此基础上,提供了设计和表示要求的两种特征,作为实际例子-针对具有在轨机动能力的近距离任务的需求,提供了具有空间计划任务目标综合的任务设计和空间段的表示-可能需要几个而不是一个协调卫星;所有这些都是通过使用电磁编队飞行方法(emff)实现的。

Este artículo de reflexión, derivado de investigación, es el resultado de un estudio exploratorio hecho por los autores. El estudio se centra en el uso tanto civil como militar actual de las órbitas satelitales terrestres y la utilización de estas en un posible conflicto internacional que requiera las capacidades espaciales de los países involucrados. El análisis se realiza a partir del marco del denominado Tratado del espacio exterior de la Organización de las Naciones Unidas. Así mismo, este estudio presenta un enfoque tanto jurídico como técnico que permite visualizar un posible conflicto y el incumplimiento del mandato de no militarización del espacio exterior. Para ello, se presentará una recopilación de antecedentes históricos de la carrera espacial centrada en aquellos hitos que han permitido a la humanidad lograr la evolución tecnológica actual. Seguidamente, se presentará un análisis normativo aplicable a las tecnologías satelitales. Además, se mostrarán referentes tecnológicos de sistemas que son usados actualmente para propósitos civiles y militares.Este estudio de contexto permitirá resaltar las amenazas y las posibilidades de un conflicto internacional mediante el análisis de las capacidades institucionales y militares que los países que son potencia en el desarrollo de tecnologías espaciales están desarrollando. Una vez se establezca que es real y latente la posibilidad del conflicto que hace uso de capacidades militares en el espacio ultraterrestre, se analizarán los aspectos principales del concepto de militarización del espacio y su respectiva normatividad. En último lugar, se presentarán las conclusiones del estudio: que a la fecha se encuentra militarizado el espacio y que es necesaria una actualización de la normativa espacial teniendo en cuenta la antigüedad de la normatividad.
这篇来自研究的反思文章是作者探索性研究的结果。这项研究的重点是目前民用和军事使用地球卫星轨道,以及在可能需要有关国家空间能力的国际冲突中使用这些轨道。这一分析是在所谓的联合国外层空间条约的框架内进行的。这项研究还提出了一种法律和技术方法,使我们能够设想可能发生的冲突和违反外层空间非军事化任务的情况。为了做到这一点,它将介绍太空竞赛的历史背景,重点是那些使人类实现当前技术进化的里程碑。然后将提出适用于卫星技术的政策分析。此外,还将展示目前用于民用和军事目的的系统的技术基准。这项背景研究将通过分析空间技术发展大国正在发展的体制和军事能力,突出国际冲突的威胁和可能性。一旦确定利用外层空间军事能力发生冲突的可能性是真实的和潜在的,将分析空间军事化概念及其各自规范的主要方面。最后,将提出研究的结论:迄今为止,空间已军事化,考虑到规范的年龄,有必要更新空间规范。

Combustibles alternativos en el transporte aéreo nacional 国内航空运输中的替代燃料
Pub Date : 2020-11-11 DOI: 10.18667/cienciaypoderaereo.643
Luisa Mónico, E. Rincón, Cristian Manuel Manrique Vega
En la actualidad, la alta demanda de pasajeros en los diferentes aeropuertos del país, el crecimiento, fortalecimiento y nacimiento de compañías aéreas junto a la necesidad de encontrar un combustible sustituto del combustible fósil y que a la vez, sea amigable con el medio ambiente, ha potencializado el estudio, implementación, uso y optimización de los combustibles alternativos en el sector de la aviación. Hoy en día, a pesar de que no se tienen numerosos ni grandes avances en la industria de la aviación, la implementación de nuevas fuentes de energía es un tema que se ha venido evaluando con el paso de los años. Por ello, surge la necesidad de conocer el estado actual del uso de estas nuevas energías, específicamente en el sector aéreo nacional, ya que se ha demostrado que Colombia tiene un gran potencial en la producción de biocombustibles a base de caña de azúcar y palma, los cuales han empezado a usarse para el funcionamiento de motores de combustión interna alternativos (gasolina y diésel). Por otra parte, la revisión bibliográfica permitió afirmar que a pesar de los escasos intentos por demostrar las grandes ventajas que tiene el uso de combustibles alternativos en la aviación nacional, los resultados han sido satisfactorios, lo cual promueve al desarrollo y empleo de una nueva fuente de energía en Colombia.
目前,该国不同机场对乘客的高需求,航空公司的增长、加强和诞生,以及寻找化石燃料替代燃料的必要性,同时对环境友好,促进了航空部门替代燃料的研究、实施、使用和优化。今天,尽管航空工业没有取得许多或重大进展,但新能源的实施是一个多年来一直在评估的问题。因此,有必要了解这些新能源的使用现状,特别是在国内航空部门,因为哥伦比亚已被证明在生产以甘蔗和棕榈为基础的生物燃料方面具有很大的潜力,这些燃料已开始用于运行替代内燃机(汽油和柴油)。另一方面,文献回顾表明,尽管很少试图证明在国内航空中使用替代燃料的巨大优势,但结果令人满意,这促进了哥伦比亚新能源的开发和使用。

The aerospace industry has evolved dramatically over the years, motivating the Colombian aerospace sector to undertake its own efforts regarding research and development. Such motivation promoted the two-phase research project that will be addressed in this work. The first part of this paper explains the methodology that was adapted to effectively conclude the first phase of the project and thus give a start to the second phase. Then, the article introduces the normative framework that supports research projects by international regulatory entities that could be adapted to national initiatives. Afterward, prior research studies on this subject and their contribution will be addressed, spanning over the history of rocketry in Colombia since the first experimental launches carried out about sixty years ago and the development of experimental protocols by Colombian universities and other institutions —including the work by San Buenaventura University (Bogotá) research group GIAS—, to finally connect these experiences with the objectives of this study. The last section presents the results obtained after the first phase of the project and what is expected during the second phase.
多年来,航空航天业发生了巨大变化,促使哥伦比亚航空航天部门在研发方面做出自己的努力。这种动机推动了这项工作将涉及的两阶段研究项目。本文的第一部分解释了为有效地结束项目的第一阶段,从而开始第二阶段而采用的方法。然后,文章介绍了支持国际监管实体的研究项目的规范框架,这些项目可以适应国家倡议。之后,将讨论之前关于这一主题的研究及其贡献,涵盖自大约60年前首次实验发射以来哥伦比亚火箭技术的历史,以及哥伦比亚大学和其他机构制定的实验方案,包括圣布埃纳文图拉大学(波哥大)研究小组GIAS的工作,最后将这些经验与本研究的目标联系起来。最后一节介绍了项目第一阶段后获得的结果以及第二阶段的预期结果。

Assessing performance is essential when a new aerospace product is being developed. Drones are considered a noble product with enormous potential for the aviation industry in the upcoming years. In this context, certified drone designing is a complex activity that requires the interaction of various areas of knowledge and that is normally approached in phases ranging from feasibility to production. Therefore, this article proposes the use of agile methodologies for the conceptual design of a drone, considering that several studies have shown the potential of this type of methods for addressing similar challenges, as in the case of software development. Scrum was the agile framework selected for the design of the device and thus better manage product complexity and process disturbances. A proposal for the application of this method, showing the different design stages, is presented in the final section of the paper.
在开发新的航空航天产品时,评估性能是必不可少的。无人机被认为是未来几年航空工业具有巨大潜力的高贵产品。在这种情况下,经过认证的无人机设计是一项复杂的活动,需要各个知识领域的相互作用,通常分阶段进行,从可行性到生产。因此,本文建议在无人机的概念设计中使用敏捷方法,考虑到一些研究已经表明这种方法在解决类似挑战方面的潜力,例如在软件开发的情况下。Scrum是为设备设计选择的敏捷框架,因此可以更好地管理产品复杂性和过程干扰。本文的最后一节给出了该方法的应用建议,展示了不同的设计阶段。

La interpretación primitiva del diseño en la fábrica argentina de helicópteros Cicaré S.A. (1956-2015) 在helicopteres cicare S.A.阿根廷工厂对设计的原始诠释(1956-2015)
Pub Date : 2020-11-11 DOI: 10.18667/cienciaypoderaereo.673
Leandro Colombano, Diego Aguiar
The technological knowledge generated by a company can be defined as the set of information coming from the design, analysis, construction and testing of its technological products, innovations, and processes (McGinn, 1991). This type of knowledge entails characteristics that make it difficult to be preserved and transmitted, particularly due to its high tacit component (Polanyi, 1966). For this reason, it is important to investigate the characteristics of this class of knowledge in order to facilitate its creation, management, conservation, and transmission. Therefore, the objective of this study is to identify the work methodology of activities associated with the design and manufacturing of helicopters, as well as the knowledge management generated and its evolution path over time in a company selected as case study. The practices and roles played by each of the actors within the company are also significant aspects to be considered. The technical analysis of all the helicopters developed by the company Cicaré s.a. has been used as source of information; although, in particular, there are not available records of this company’s activities or financial statements over time. Interviews with people related to the current firm and its history have been fundamental. Cicaré s.a. is an Argentinian aeronautical company working in the development and manufacturing of internationally recognized helicopters. It is considered a benchmark in the industry for the innovations it has developed on this type of aircraft, which are used today throughout the world. The first vertical flight in South America, the development of one of the first ultralight helicopters and a real controlled flight simulator are some of the firm’s main innovations. This study seeks to identify the coexistence of two design and innovation methodologies applied to aeronautical technology by this company. On the one hand, there is a production department that, using standard engineering methodology (Mott, 1995), produces serial helicopters. Besides, a research and development department applies prototype analysis methodology (Gero, 1990) looking for innovations and product improvements.
公司产生的技术知识可以定义为来自其技术产品、创新和工艺的设计、分析、构建和测试的一组信息(McGinn,1991)。这种类型的知识具有难以保存和传播的特征,特别是由于其高度隐含的成分(Polanyi,1966)。因此,研究这类知识的特征以促进其创造、管理、保存和传播是很重要的。因此,本研究的目的是确定直升机设计和制造相关活动的工作方法,以及所产生的知识管理及其在一家被选为案例研究的公司中随时间的演变路径。公司内部每个参与者的做法和角色也是需要考虑的重要方面。Cicarés.a.公司开发的所有直升机的技术分析都被用作信息来源;尽管,特别是,没有这家公司的活动记录或财务报表。采访与当前公司及其历史相关的人是至关重要的。Cicarés.a.是一家阿根廷航空公司,致力于开发和制造国际公认的直升机。它被认为是该行业在这种飞机上开发的创新的基准,这种飞机目前在世界各地使用。南美洲的首次垂直飞行、首批超轻型直升机的开发和真正的受控飞行模拟器是该公司的一些主要创新。本研究旨在确定该公司应用于航空技术的两种设计和创新方法的共存性。一方面,有一个生产部门,使用标准工程方法(Mott,1995)生产系列直升机。此外,一个研发部门应用原型分析方法(Gero,1990)寻求创新和产品改进。

Interviews with people related to the current firm and its history have been fundamental. Cicaré s.a. is an Argentinian aeronautical company working in the development and manufacturing of internationally recognized helicopters. It is considered a benchmark in the industry for the innovations it has developed on this type of aircraft, which are used today throughout the world. The first vertical flight in South America, the development of one of the first ultralight helicopters and a real controlled flight simulator are some of the firm’s main innovations. This study seeks to identify the coexistence of two design and innovation methodologies applied to aeronautical technology by this company. On the one hand, there is a production department that, using standard engineering methodology (Mott, 1995), produces serial helicopters. Besides, a research and development department applies prototype analysis methodology (Gero, 1990) looking for innovations and product improvements.","PeriodicalId":31120,"journal":{"name":"Ciencia y Poder Aereo","volume":"15 1","pages":"122-142"},"PeriodicalIF":0.0,"publicationDate":"2020-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47165719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research seeks to estimate the incidence of burnout syndrome, also known as occupational burnout syndrome, and its relationship with the administrative and operational workload of th-67 pilot instructors at the Helicopter School of the Colombian Armed Forces. A descriptive and cross-sectional study was carried out in order to identify the presence of burnout syndrome. The study involved the application of the Maslach Burnout Inventory, which evaluates three dimensions: personal accomplishment, emotional exhaustion, and depersonalization. In addition, the association with the working conditions of flight instructors in regard to training and flight operations as well as administrative and military tasks were also considered in this study. The results showed that burnout syndrome is not a frequent condition in pilot instructors, since emotional exhaustion and depersonalization dimensions reported low levels in most participants, while personal fulfillment recorded high levels. Besides, no association was observed between the studied labor factors (hours of training, time in an administrative position, hours in an additional position, administrative burden, and number of years as a th-67 instructor).
本研究旨在估计哥伦比亚武装部队直升机学校第67飞行员教官的倦怠综合征(也称为职业倦怠综合征)的发生率及其与行政和操作工作量的关系。为了确定倦怠综合征的存在,进行了一项描述性和横断面研究。这项研究涉及Maslach倦怠量表的应用,该量表评估了三个维度:个人成就、情绪衰竭和人格解体。此外,本研究还考虑了飞行教官在训练和飞行操作以及行政和军事任务方面的工作条件。结果表明,倦怠综合征在飞行员教官中并不常见,因为大多数参与者的情绪衰竭和人格解体维度较低,而个人成就感则较高。此外,所研究的劳动因素(培训时间、行政职位时间、额外职位时间、行政负担和担任第67任教员的年限)之间没有关联。
