<Ease of maintenance>

Inspection holes are provided at suitable locations so that all flow path faces can be inspected without disassembly. As in existing Kawasaki models, the high-temperature

section of the gas generator module is structured as a horizontally split casing and a multi-can combustor with the aim of shortening the maintenance time for periodic

replacement. In addition, a modular structure design enables easy and fast replacement work in overhauls.
