课程名称：新空间：访问太空 - 基础知识 课程概述： 新空间（NewSpace）的精神正在革新我们对访问太空的认识。通过阅读关键内容，您将能够理解在新规则下，雄心勃勃的参与者所面临的技术和战略挑战。本课程将新技术与太空获取的管理结合起来，并与现有的太空背景的经典范式相对比。尽管很难给新空间下一个确切的定义，但我们可以指出几个特征：创新、私营参与者、降低访问太空的价格、让太空为所有人开放，以及对社会挑战的意识。 在本课程中，您将首先掌握必备的基础知识，以理解如何进入太空。这将涉及任务分析、发射器和火箭发动机设计。这些入门信息将帮助您理解新空间中访问太空所特有的三个主要方面： 1. 发射器和火箭的设计、开发及生产方法 2. 创新技术 3. 可持续太空及未来绿色发射器的发展方向 课程大纲： 1. 介绍 2. 发射器 - 新空间是一个广泛的概念，诞生于十多年前。虽然很难下定论，但探索新空间对轨道运输的影响相对可行。访问太空是关键。在这一领域，革命性的变化已发生，源于“传统太空”所发展成果的成熟。不同的平衡被修改，本课程恰恰展示了在访问太空方面的新空间所面临的主要问题、机遇、技术和前景。 3. 火箭发动机基础 - 推进系统是任何发射载具中最重要的子系统：它提供完成任务所需的推力和比冲。我希望在本周中向您介绍用于太空获取的发射载具中的火箭发动机。您将理解推进系统的基本原理，并了解如何将推进系统与发射载具的任务分析联系起来。这将使您在下一周了解到新空间中的颠覆性技术和创新方法如何影响火箭发动机的未来发展。本周将介绍火箭发动机的工作原理、功率的量级以及基本性能参数，然后将呈现不同类型的火箭发动机：液体、固体和混合型。最后，将专注于液体推进剂发动机技术的子系统和循环。 4. 新空间与太空访问 - 在这一周，您将能理解新空间中访问太空的主要特征。利用第一周关于任务分析和第二周关于推进系统的知识，您将能够理解新空间如何影响发射器和火箭的设计、生产和使用。本周我们将概述生产方法论及新空间火箭和发射器的主要颠覆性技术。最后，我们将讨论可持续太空，强调新空间引发的问题及可采取的行动。 5. 总体评估 - 在这个最终的评分评估中，您将校验您的知识并进行应用。 本课程将为您提供通往新空间的基础，通过对相关技术和管理方法的探讨，帮助您把握未来太空发展的脉搏。
Name:Introduction
Description:
Name:The launchers
Description:The NewSpace is a wide concept that emerged more than ten years. It is difficult to define, but it is relatively feasible to explore the consequences of NewSpace on orbital transportation. The access to space, that’s the major point. In this field, a real revolution has taken place. It is the result of several factors, which are actually the maturity of what was developed in the "traditional space" (or classical) that still has its full place today. The balances have been modified, and this Mooc presents precisely - for access to space - the main issues, openings, technologies, and perspectives that are offered to us.
Name:Rocket engines basics
Description:The propulsion system is the most important subsystem of any launch vehicle: it provides the thrust and Isp needed to complete the mission. The objective of this week is to provide you with an introduction to the rocket engines used in launch vehicles for space access. You will understand the fundamentals of propulsion systems, and you will understand how to relate the propulsion system to the launch vehicle mission analysis. This will allow you to understand, next week, how disruptive technologies and innovative methodologies in the new space affect the future generation of rocket engines. The week starts with an introduction to how rocket engines work, some orders of magnitude of power, and an introduction to fundamental performance parameters. Then the different types of rocket engines will be presented: liquid, solid, and hybrid. The week will end with a focus on liquid propellant engine technologies: subsystems and cycles.
Name:Newspace for space access
Description:In this week you will be able to understand what are the main aspects that characterize access to space in the new space. Using the knowledge you gained in week 1 on mission analysis and week 2 on propulsion systems, you will be able to understand how the design, production, and use of launchers and rockets are affected by the New Space. During this week, we will give you an overview of the production methodologies and the main disruptive technologies that characterize New Space rockets and launchers. Finally, we will discuss sustainable space, highlighting both the issues raised by New Space and the actions that could be taken.
Name:General assessment
Description:In this final graded assessment, you will check your knowledge and apply it.
The spirit of NewSpace is revolutionizing our vision of access to space. Reading keys will enable you to understand the technological and strategic challenges in games with new rules, fixed by ambitious players. Combine the new technologies and management of space access with the classical paradigm of the existing space context. It is difficult to give a definition of the New Space, but we can say that there are several aspects that characterize the New Space and access to space in the New Space: innovation, private actors, reducing the price of access to space, space for all, awareness of societal challenges. In this course, you will first acquire basic knowledge to understand how to access space. This will concern mission analysis, launchers, and rocket engines design. This introductory information will help you to understand what characterizes space access in the New Space in relation to three main aspects: 1. Methodologies of design, development, and production of launchers and rockets 2. Innovative technologies 3. Sustainable space with the future development of green launchers, towards a green space
