Abstract
The invention relates to a thrust reverser for the jet engine of an aircraft. According to the invention, the unlocking of the doors with a view to passage from their folded position to their extended position, is effective only after they have been previously brought into a super-retracted position with respect to the folded position and said reverser comprises stops which allow the doors to pass from the folded position to the super-retracted position only when the rpm of said engine is lower than a threshold close to idling rpm. The invention is particularly applicable to ensuring operational safety of thrust reversers.
