Most of the class responded that Professor Epstein's teaching style was interesting and helped enliven the class. Many remarked that examples given from his broad industrial experience greatly enhanced their understanding and enjoyment of the subject matter. Half of the class said that lecture and the problem sets were most helpful in understanding the material; several others remarked that the texts were most helpful. The reference texts were used by at least half of the class, two of whom especially recommended Mattingly's text. Over half said that a good thermodynamics and fluids background was important to do well in the class.

The largest complaint about the class concerned the problem sets. All but one student remarked the sets were either too difficult, too long, or just not clear enough. Several said that the level of the problem sets was beyond that taught in class, and they had to seek help outside of lecture. A few also commented on the exams being too long and difficult, and one student thought that they weighted too much in the final grade, especially given the long problem sets. Some students felt weekly recitations would help the class greatly; the other most common suggestion was to lower the complexity of the problem sets.

The overwhelming opinion about the class was very positive; many called it an excellent class which gave them a very good background in aircraft gas turbines. The students thought it was interesting, and despite the difficulty of the problem sets, several highly recommended it.

"It was one of the most interesting classes I ever had, but at the same time was one of the most difficult."

"Problem sets should be better structured. A lot of time wasted in trial and error and making wrong assumptions"

"Prof's outside experience makes the class much more interesting."
