Supersonic flow modelling thrusts forward airframe-engine design integration of large twin aircraft

Aeroacoustic researchers in Engineering developed with Airbus France an integrated time-resolved model of the supersonic dual-jet and of its broad-band shock-associated noise, for large twin aircraft at cruise conditions. The tool enables a multi-disciplinary system optimization of both flow and noise, towards more environmentally friendly, fuel-efficient, quieter aircraft.

The model reveals the critical role of organised structures in the secondary nozzle shear-layer in generating ‘noisy’ interactions and an uneven jet plume, producing an intense acoustic field that radiates towards the fuselage. Changes in the jet structure aim to help cutting CO2 emissions by 75% and noise by 65% by 2050.
