This course comes with a promise - any query of yours will be replied and resolved within 24 hours. Sundays included!
Helicopters are one of the most under-rated marvels of engineering. The one that works, where no other flying machine can even think off! A helicopter appears a simple machine with just two sets of rotating blades, but then and there the simplicity ends. The amount of engineering complexity that is handled in balancing an inherently unstable flying machine is mind-blowing.
Top features of the course —
All lectures are real white-board lectures with diagrams and explanations made in an engaging manner. You will watch me in the person doing all the stuff on the board. (I hate PowerPoint presentations, and I know you too!)
All queries will be replied within 24 hours. No excuses.
On completion of course you will have a strong understanding of How a Helicopter works in detail and the various engineering blocks that go underneath.
What are pre-requisites?
You should be able to understand my English accent. So, please check the preview lectures to see if that holds good.
You have basic knowledge of physics - so things like Newton's laws of motion, vectors, gravity, shouldn't be new to you.
A system with internet to watch the videos and complete the course.
Curiosity to Learn.
FAQs
What the course is all about?
The course is about understanding how Helicopters work, from basics. All concepts can be explained just using school level physics. There is no need to unnecessarily complicate the beautiful subject.
What makes this course different?
The usage of live whiteboard style lectures will make it very engaging to learn. I ensure throughout the course to avoid any jargon and short-forms that are quite common in this subject. This will enable you to "Learn" Helicopter and not memorize it!
Also, I have tried to not leave any aspect related to this subject. So, all fundamental aspects of Helicopters are covered.
What if any topics aren't covered?
I love this subject and would respond to new topic suggestions by creating more content regularly. The course curriculum is not a fixed one.
Format of the course?
95% of the course is in video format.
Any certificates?
Yes! All students who complete the course will receive a signed certificate.
Anything else?
Go and watch the preview lectures, check out the curriculum. If you are able to comprehend the lectures then go for it and be part of an exciting journey on Learning Helicopters!
