Abstract
Solid oxide fuel cell-gas turbine (SOFC-GT) propulsion system using hydrogen fuel, is a promising
option to minimize climate impact of aviation. However, a slower response time is one possible
outcomes of utilizing SOFC-GT, which affects aircraft performance, particularly in transient scenarios such as go-arounds. The effect of engine response times on the flight trajectory of a go-around manoeuvre are investigated numerically by solving an optimal control problem that minimizes the time needed to perform the manoeuvre. Results shows a 111% more altitude loss by operating an engine with a 20 seconds response time compared to a 5 seconds engine.
