Foundation of Structural Dynamics
ISAE-SUPAERO (via Coursera)
A course with variable geometry where everyone, we hope, will find personal benefits. The parts can be studied sequentially or independently; and inside each part, elementary learning items can be picked up. Globally, this course proposes a deep knowledge of fundamental dynamics, with possible explicit and implicit applications in structural dynamics, but also in physics and control of any dynamic system (automatics, …). The concepts of static, dynamic, and thermodynamic approaches are defined, followed by the analytical Newtonian foundations of discrete (digital) dynamics. Dynamics is not simply an extension of statics, but another modeling with open possibilities. The basic theorems (Newton‘s equivalence principle, König’ s theorems, conservations) are detailed in the perspective of structural applications. This course opens perspectives towards not only the general dynamics of structures but also towards robotics and control of dynamic systems. These concepts will be learned in a second course (Developments of structural dynamics).
Flight mechanics - Propulsive balance and energy
ISAE-SUPAERO (via Coursera)
This course is dedicated to energy management, i.e. speed and altitude control. The various sources of drag are first described and modeled, as well as thrust origin, and evolution with speed and altitude. Using these models, we can evaluate the propulsive balance and derive important concepts like flight regimes, best climb speed, or propulsion ceiling. We take then a glance at cruise performances and the evolution of range with weight. This course is a part of the specialization "Fundamentals of Flight mechanics".
Flight Mechanics - Anemobarometry
ISAE-SUPAERO (via Coursera)
This course focuses on the physics of the atmosphere and its consequences on speed and altitude measurements. At the end of this course, you will understand precisely the meaning of the speed and altitude indication available to the pilot of an airplane. You will understand the difference between standard and actual atmosphere and be able to perform basic altitude and speed correction computations. You will understand why jet airliners need to be pressurized, or why a clogged Pitot tube can mislead a pilot. Although some math equations are used from time to time to justify certain results. This course insists on curve shapes, figures, tables, and you can efficiently follow it while skipping the equation-solving parts if you do not fancy them. This course is a part of the specialization "Fundamentals of Flight mechanics".
Developments of structural dynamics
ISAE-SUPAERO (via Coursera)
This course is devoted to the dynamic implementation of continuous structural elements vs discrete models. The matrix representation and implicit solution of Lagrange’s equation are at the heart of this approach, in the framework of conservative structural systems, with Gaussian modes. The prototype of the continuous element being the prismatic beam - as an illustration, but with general value - and the implicit model/solution leads to the major place of natural eigenshapes in vibration and shocks theory and general dynamic representation of structures and foundations of the dynamic tests and certification. In fact, this course is a perspective on the double vision of any dynamic structure, with the continuous point of view and a digital model in perspective. At the end of this course, the physicist, the mechanical engineer, the specialist in control will have a general overview of the dynamic representation and implicit solution applicable in structural analysis and control of general dynamic systems. In a certain way, it is founded on the famous discussions between Albert Einstein and Niels Bohr. Recommendation: we suggest having a look, at the course "Foundation of structural dynamics: from static to discrete dynamics". This course proposes an original point of view of the foundations of dynamics. And could highlight the present course.
Flight mechanics - Lift and trajectory
ISAE-SUPAERO (via Coursera)
In this course, you will understand the influence of the angle of attack and speed on the lift. Then we will focus on hazards and limitations, like stall, spiral dive, or flutter. You will understand why stall phenomenon and Mach number limit the maximum lift and altitude the airplane can achieve. Then, you must understand what is flutter and why the altitude and speed of the airplane must be restricted to a safe domain. In the end, we will explain how to control the trajectory of the airplane and the relation with lift and load factor. This course is a part of the specialization "Fundamentals of Flight mechanics".
Introduction to Aircraft Airworthiness
ISAE-SUPAERO (via Coursera)
ISAE-SUPAERO and ENAC, two academic and research leaders in the field of aviation and aerospace engineering, join to propose a course about the basics of aircraft airworthiness. At the end of this course, you will be able to identify the applicable processes and technical requirements to ensure safety and environmental protection level of an aircraft, from its design to its end-of-life: identify an acceptable level of safety describe roles and responsibilities of stakeholders describe the principles required to ensure that an aircraft design will meet applicable requirements describe the principles required to ensure that an aircraft remains safe and compliant with environmental requirements when in operation. ISAE-SUPAERO and ENAC are based in Toulouse, France, at the heart of a dynamic civil and military aeronautical ecosystem that shapes the future of global aerospace.
Flight mechanics - The basis
ISAE-SUPAERO (via Coursera)
More than one century after the Wright brothers' first flight, the flight still defy our intuition. You will learn here how to name the different parts of the airplane and how to describe and quantify its geometry. For that, we need now to share a precise vocabulary to describe the airplane's movement and attitude in space, and a refresher on basic general mechanic principles. You will remind how Newton's 2nd law allows you to determine what force must be applied on an apple - or on an airplane, to modify the magnitude and direction of its speed. Coming back on the concepts of kinetic energy and potential energy, you will discover the very useful concept of total height and you will be able to explain how an airplane can quickly exchange speed for altitude, while changes in total height are much slower. In the end, you will discover that only a very small number of forces apply on an airplane in flight and that you will be able to classify those that change its energy state and those that modify its trajectory. You will discover the concept of load factor and understand why the pilot of a combat aircraft can feel a weight nine-time greater than his actual weight! Finally, we will establish the lift and propulsion equations, that form the basis of flight mechanics, and you will be able to compute the lift and thrust necessary to follow a given trajectory at a given speed. This course is for anybody interested in learning more about how planes work, the physics of flying, or flight mechanics. It will be of particular interest to undergraduate students in aerospace engineering, trainees as well as senior pilots, journalists, and professionals in the aeronautics sector. Although some mathematical formalism may be present sometimes. It is always doubled by sketches, figures, and hands-explanations. So that, anybody can skip the formulas without losing the core understanding of the concepts. No apples were harmed in the making of this course... This course is only a...
New Space: Access to space - Basics
ISAE-SUPAERO (via Coursera)
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
