Abstract
A closing system for a fan cowling on a jet engine of an aircraft that has at least one assembly including a male contrivance integral with the cowling, and a female contrivance integral with the jet engine that has a lower element forming at least one first guide ramp and an upper element forming at least one second guide ramp, with the aforementioned female contrivance being suitable on the one hand for guiding the male contrivance during the opening and/or the closing of the fan cowling, and on the other hand providing a limitation of the radial and circumferential displacements of the male contrivance.
Claims9
An aircraft nacelle with a system for closing a fan cowling on a jet engine of the aircraft, the system comprising:
- at least one assembly mounted on one side of the nacelle, the at least one assembly comprising:
- a male contrivance integral with the cowling, and
- a female contrivance integral with the jet engine, the female contrivance comprising:
- a lower element forming at least one first guide ramp and an upper element forming at least one second guide ramp, the first guide ramp providing a radial displacement limitation of the male contrivance and the second guide ramp providing a circumferential displacement limitation of the male contrivance when the cowling moves outward from the engine,
- wherein the male contrivance comprises a first face facing the first guide ramp and a second face parallel to the first face, the second face facing the second guide ramp, when the male contrivance is disposed between the upper element and the lower element, and wherein the first guide ramp and the second guide ramp prevent scooping of the cowling.
