I am be interested in learning more about propulsions systems on aircraft, and realize a good understanding of thermo would help tremendously. I just read one of the Dover books, Understanding Thermodynamics to help get some of the basics down and now would like to take a step up to the next level. My understanding of thermo besides this book is very little where it was briefly discussed in chemistry last semester. In the fall I will be taking fundamentals of thermodynamics and the following spring a class on propulsion, but I'd like to go ahead and start learning about this subject. Would it be okay to jump to an introductory book on propulsion with my little background in thermo or should I try to get a better understanding of thermo first? Any suggestions of good books that are suited for my level would be great. Thanks!
