Course Description

A flow is called hypersonic if the Mach number is greater than 5. This means that the flow speed is more than five times the speed of sound. In air at room temperature, the speed of sound is around 340 m/s, so a Mach 5 flow would have a flow speed of 1.7 km/s or just over 6,000 km/h. When a rocket launches a satellite into earth orbit, when a probe enters the atmosphere of another planet or when an aircraft is propelled by a supersonic combustion ramjet engine (a scramjet), hypersonic flows are encountered. Hypersonics – from Shock Waves to Scramjets introduces the basic concepts associated with flight at speeds greater than Mach 5 and takes students to the stage where they can analyse the performance of a scramjet engine that might be used in a future access-to-space system.

A fantastic platform to apply the basic concepts of thermodynamics and fluid dynamics in a real world situation to analyse the performance of a scramjet engine. The instructors had a deep knowledge of the subject and more importantly conveyed it brilliantly. A must for all those interested in the field of aeronautics

I am a first year Mechanical Engineering student and I found this course amazingly instructive and deep in terms of how complex jet engines are simplified with the main aim of giving learners the opportunity to comprehend the tools and techniques used in the development of Scramjet engine. The course is designed for students from any background with basic knowledge of physical sciences to be able to understand the complexity of such engines in a simplified yet detailed manner. Thumbs up to all the lecturers at the University of Queensland. Hoping to see more courses like this.

Prior experience: Previous work with compressible flow and hypersonic flow field analysis in CFD. The course is very thorough in the way it introduces the concepts of hypersonic flight and scramjet vehicles step by step, building upon each section in order to achieve its objective: the project (simplified, of course) of a scramjet engine in all its components. This allows the student to grasp the behavior of the flow fields at each component of a scramjet and see the bigger picture of the entire engine. The course was definitely well structured, with no hesitation to develop pertinent equations and analyzing its components, showing well the physical implications of the mathematical formulation. I certainly recommend this course to anyone in the field and also to anyone who is interested in hypersonics, but without prior experience.

The quality of the lectures was a bit uneven. Some of the lecturers summarized their equations in the accompanying text while others left us trying to read their scribbles on the board in the videos. Overall, the course was very good; I learned a lot. I took the course strictly for fun, and fun it was.

I took the course as an auditor to introduce myself to the subject material. Much of it was over my head, but it provided the ground work that I was looking for to understand what hypersonic flight and problems of hypersonic flight are all about. The presentation was very good, and a novice like me could follow along and glean almost everything from the course shy of being able to actually apply the engineering and physical concepts to the actual design of a scram-jet.

I work in the field of hypersonics research. I can not compare this course to others as this was the first time I took an online course. The course is well organized for good understanding and have a nice learning curve. If you are an young engineer and do want to learn more about future air breathing jet engines this course is a must. The University of Queensland is the leading research institution in this subject in my opinion.

I agree with a previous reviewer. Professor Morgan kept me on my toes with some note taking, and even so still had some difficulties in certain sections. I still loved the course regardless. A lot fun! I personally used a spread sheet to keep track of, especially near the end, the more long winded aspects of computations, or if you have it some favorite math software handy as a computational aid, preferably something that can be used for sequential computations (especially where if having to change parameters at the outset, this wouldn't leave with you with the same set of work in reformulating answers. Final project had an interconnected series of computations, over 50+ steps, but generally straight forward in terms of problem solving. I highly recommend compressible flow calculator for use here, this being the case if you decide to take the course for the full blown mathematics sides of things!

This was a very good course with very good choice of material from this complex field of scramjet design.  The lectures were well done  and quite understandable.  The questions were practical and instructive.  The contact with the professors through the discussion group was very good.  The final project tied everything together very nicely and demonstrated the student's new ability to understand and analyze scramjet engines.

I enjoyed the course immensely & only took it to have something to audit & keep the brain working at the current contract job I had. All the teachers were very clear & explained the subject well. I unfortunately had to drop it because the location I was working has terrible internet speed & found that during a typical 1 hr lunch I was waiting for the internet to catch up about 55 of those minutes. very frustrating so I stopped wasting my time! But all in all I was very pleased & will be taking more classes thru EDX when my next job has reasonable internet speed.

Professors David Mee and Vincent Wheatly were amazing. Their lecture delivery and topic explanation with complete clarity and dwelling deep into the fundamental concept approach was brilliant. I was able to clear my hypersonics' fundamentals to a very good extent. On the other hand, Professor Morgan's lectures were highly confusing and unclear. The concept of the theoretical project analysis was very good. I enjoyed analyzing the scramjet conditions and finally was able to calculate the specific impulse accurately. However, the 2% error margin proposed was relative to some very specific values, and therefore the calculation of even the correct values was sometimes misleading. The numerical values used in every successive calculation using the aerodynamics calculator was taken by the staff or their pre installed algorithm, as to be approximated to a 'confusing' number of significant figures, which led to highly confusing and bizarre...

I would suggest the staff to mention specifically the number of significant figures required in the answers, so that errors in the successive problems can be minimized. Finally, I am satisfied to have completed the course as an ID verified student and 89% grade.
