Abstract
This study aims at developing a NEA flow estimation method to secure the necessary technology for applying OBIGGS (On-Board Inert Gas Generating System) to aircraft. For this purpose, the change in oxygen concentration in the fuel tank according to the NEA flow rate and concentration supplied to the fuel tank of the aircraft is estimated and validated.First, based on the theory of perfect mixed assumption, the average oxygen concentration change inside the fuel tank was calculated. Tests for validation of the predicted results are carried out by considering the aircraft operating environment (altitude change). Then, a simplified fuel tank model was applied without implementing complicated fuel tanks such as actual aircraft.
