FIELD: engines and pumps.

SUBSTANCE: turbojet comprises front blower, intermediate housing with outer shell and hub arranged behind the blower and interconnected by radial arms, and outlet housing with outer shell. Engine housings are aligned in XX axis. Pylon comprises elongated torsion box rigidly attached at the front to intermediate housing outer shell by front fastener including means to transfer axial and lateral force and, at the rear, to outlet housing by rear fastener. Torsion box front attachment takes up axial forces parallel with XX axis, vertical and transverse forces perpendicular to both axial and vertical directions, and takes up torque around axial direction. Front attachment comprises horizontal plate in plane defined by axial and transverse directions and ranged on base rigidly jointed to intermediate housing outer shell, shear pin extending in vertical direction to cross said plate and base, and two slammer links shaped to lever V. Front ends of smaller links make V vertex secured to intermediate housing shell.

EFFECT: reduced forces acting between engine front and rear parts.
