Abstract
Official abstract text for this publication.
A driveshaft misalignment measurement system for a drivetrain of an aircraft includes a driveshaft having a first end forming a driveshaft spline and a drivetrain subsystem including a spline adapted to connect to the driveshaft spline to form a splined connection. Rotational energy is transferred between the drivetrain subsystem and the driveshaft via the splined connection. The driveshaft misalignment measurement system also includes accelerometers coupled to the drivetrain configured to detect acceleration data and a flight control computer configured to measure misalignment at the splined connection using the acceleration data.
First claim
Opening claim text (preview).
What is claimed is: 1. A driveshaft misalignment measurement system for a drivetrain of an aircraft comprising: a driveshaft having a first end forming a driveshaft engine spline and a second end forming a driveshaft gearbox spline; a drivetrain subsystem including an engine and a gearbox each including a spline adapted to connect to a respective one of the driveshaft splines to form first and second splined connections, rotational energy transferred from the engine to the gearb…
