To this end, Onera has already carried out several experimental and numericalstudies with the aim of characterizing the shielding effect that a tail plane might have on" the downstream" fan noise of a dual flow nozzle. The numericalstudies were performed using the sAbrinA calculation software, which can simulate the complex phenomena of acoustic generation and propagation
Onera's teams had begun studies which would contribute to define and design the plane even before" the A3XX" project was launched in August 1994. For the last 10 years, some 340 Onera staff members have been involved in the development of the A380. Onera has also provided its outstanding testing facilities and its most sophisticated modeling and simulation tools, which contributed greatly to the success of the A380 program
