Abstract
An engine attachment pylon for an aircraft including a rigid structure including a box including an upper spar and a lower spar, connected to each other through two lateral panels. At least one of the upper and lower ends of the web of at least one of the two lateral panels includes at least one assembly cleat projecting sideways from the web towards the outside of the box, and assembled to the spar on which it bears through an attachment mechanism located outside the inner space in the box.
Claims12
An engine attachment pylon for an aircraft, the pylon comprising:
- a rigid structure including a box, the box including an upper spar and a lower spar connected to each other by two lateral panels, the two lateral panels extending in a longitudinal direction of the engine,
- wherein each of the two lateral panels includes a web delimiting a side space inside the box where an upper end of the web faces the upper spar and a lower end of the web faces the lower spar,
- wherein at least one of the upper end of the web and the lower end of the web of at least one of the two lateral panels includes at least one assembly cleat projecting sideways from the web towards an outside of the box and in a direction substantially perpendicular to the longitudinal direction of the engine, and
- wherein the at least one assembly cleat is assembled to one of the upper spar and the lower spar via an attachment mechanism located outside the inner space of the box.
An engine attachment pylon for an aircraft, the pylon comprising:
- a rigid structure including a box, the box including an upper spar and a lower spar connected to each other by two lateral panels;
- and
- two lateral aerodynamic skins fixed on the box of the rigid structure,
- wherein each of the two lateral panels includes a web delimiting a side space inside the box where an upper end of the web faces the upper spar and a lower end of the web faces the lower spar,
- wherein at least one of the upper end of the web and the lower end of the web of at least one of the two lateral panels includes at least one assembly cleat projecting sideways from the web towards an outside of the box,
- wherein the at least one assembly cleat is assembled to one of the upper spar and the lower spar via an attachment mechanism located outside the inner space of the box,
- wherein each of the two lateral aerodynamic skins faces the web of one of the two lateral panels and is at a distance away from the web, and
- wherein each lateral skin and the lateral panel facing the lateral skin form a compartment of the pylon through which at least one of hydraulic and electrical systems pass.
