17.1 Introduction

In the previous chapter, we studied reciprocating IC engines which operate on a gas power cycle. In this chapter, we will study gas turbines which are rotary type engines also operating on a gas power cycle. In the same way as reciprocating IC engines dominate the earth’s surface by being the sole choice for automobiles, ...
