The statement is correct. In an open-cycle gas-turbine engine, the isobaric heat rejection process that is part of the theoretical Brayton cycle does not exist.

Here's why:

1. The Brayton cycle consists of four processes: isentropic compression, isobaric heat addition, isentropic expansion, and isobaric heat rejection.

2. In an open-cycle gas-turbine engine, air is drawn in from the atmosphere, compressed, heated by burning fuel, and then expanded to do work on the turbine. The exhaust gases are then released back into the atmosphere.

3. This process corresponds to the first three processes of the Brayton cycle (isentropic compression, isobaric heat addition, isentropic expansion). However, the isobaric heat rejection process does not occur in an open
