Abstract
A fail safe emergency lock for a thrust reverser is disclosed in which the thrust reverser is located on a jet engine having a cowling bounding a gas flow duct, the cowling having at least one reverse thrust opening in communication with the gas flow duct. The thrust reverser has a thrust reverser panel movably mounted on the cowling so as to be movable between a forward thrust position, in which the thrust reverser panel covers the reverse thrust opening, and a reverse thrust position in which the reverse thrust opening is uncovered. The thrust reverser also includes an emergency lock to lock the thrust reverser panel near the forward thrust position in which the lock has a support fixedly attached to either the cowling or the thrust reverser panel, a strike plate slidably located on the support, a plastically deformable element located between the support (32) and the strike plate, (31) and a lock bolt (25, 25a) movably located on the other of the cowling and thrust reverser panel so as to be moveable between an unlocked position and a locked position in which the lock bolt engages the strike plate. The arrangement of the elements are such that movement of the thrust reverser panel relative to the cowling away from the forward thrust position causes relative movement between the strike plate (31) and the support, (32) thereby causing plastic deformation of the plastically deformable element (42, 42a) and preventing further movement of the thrust reverser panel toward the reverse thrust position.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
