Abstract

Official abstract text for this publication.

A shaft break detection system and a method of detecting shaft break for a gas turbine engine. A first indication is calculated from measured rotational speed of a shaft. A second indication is calculated from the rotational speed. A shaft break signal is generated if both indications are true.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of detecting shaft break for a gas turbine engine, comprising the steps of: measuring rotational speed of a shaft of a gas turbine engine; calculating a first indication from the rotational speed; calculating a second indication from the rotational speed, wherein each of the first indication and the second indication is a Boolean logic value; and producing a shaft break signal if the first indication is true and the second indication is…
