Numerical Simulations of High Temperature Jets from the Main Propulsion System and Auxiliary Power Unit Impinging Against a Construction of the Passenger Plane
Newly designed passenger aircraft should meet safety and reliability requirements in imaginable emergency situations, one of which is the burn-through of a combustion chamber body of the main propulsion system (MPS) and of the auxiliary power unit (APU), both on the ground and in-flight. In accordance with the international safety standards, an emergency case is investigated using STAR-CCM+ and Abaqus in which, due to local disruption of the combustion chamber, a flame jet is erupted. As a result of the flame jet impingement some parts of the aircraft fuselage can substantially be heated,...
