The Su-57's distinctive howl is a symphony of factors orchestrated by its engine design and air intake shape. Its powerful AL-41F engines generate intense airflow, which interacts with the sharp edges and internal structures of the S-duct air intakes, creating high-pitched vibrations. These vibrations resonate through the airframe, resulting in that signature howl, earning the Su-57 nicknames like "Screaming Felon." While the sound offers a dramatic warning, it's not all about aesthetics - the engine design prioritizes performance over stealth, sacrificing some radar invisibility for raw power and agility. So, the Su-57's howl reflects both its fearsome capabilities and its unique design trade-offs, a sonic signature that announces its presence in the skies.
