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.

Along this first week, we want you to get acquainted to the airplane. We will first learn how to name the different parts of the airplane and how to describe and quantify its geometry. And we will see through an exercise that concepts that seem well defined, like the surface of the wing (wing surface), can be, in practice, difficult to measure. This part will allow us to share a common and precise vocabulary.

We need now to share a precise vocabulary to describe the airplane's movement and attitude in space, and a refresher on basic general mechanics principles. You will review how Newton's second 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. To conclude this week, we invite you on a tour of our full flight simulator Pegasus (Pegase in French), to see how clever use of those concepts in a Head-Up Display might allow you to conduct a perfect approach and landing without a single glance at your speed or altitude indicators.

It's time to apply your knowledge to the airplane! You will discover that only a very small number of forces apply on an airplane in flight and that you are 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! You will come on board our DR400 light airplane (not a combat airplane indeed) with Newton's apple to better understand what this load factor actually means. Finally, you 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. No apples were harmed in the making of this course.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.
