The Brayton Cycle
“What is the fundamental process for jet engines?”
Jet engines are some of the most advanced pieces of technology in the world. However, how exactly do they work? Well, let’s use our engineering mindset to find out. First, let’s start with a working fluid, and compress it in an adiabatic manner for Part 1. Afterwards, let’s inject some fuel to induce a constant pressure explosion in Part 2. This should cause an adiabatic expansion for Part 3. To finish everything off, let’s go through with a constant pressure heat rejection in Part 4. This cycle is known as The Brayton Cycle and the efficiency can be given by the equation Nu = 1 – t1/t2 = 1 – (p1/p2)^((k-1)/k).
