FIELD: aviation.
SUBSTANCE: inner wall of nacelle includes a monolithic layered structure based on superplastic forming and diffusion binding, monolithic layered structure comprises a core disposed between the first and second facing sheets with formation of a layered structure. Moreover, the core includes a plurality of cells, and the first facing sheet has a plurality of wholes to ensure the arrival of noise and air into the cells.
EFFECT: higher structural strength and high resistance to damage, heat resistance, noise reduction without increasing the weight of the structure are achieved.
