Abstract
Official abstract text for this publication.
System and methods for servicing and monitoring shock struts are provided. A shock strut servicing assistance system may comprise: a controller in electronic communication with a display; and a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising: calculating, by the controller, a dead volume of a shock strut and determining, by the controller, a first decision, the first decision being whether or not the dead volume of the shock strut is negative. A shock strut servicing assistance system may be for servicing a shock strut having a negative dead volume.
First claim
Opening claim text (preview).
What is claimed is: 1. A shock strut servicing assistance system, comprising: a controller in electronic communication with a display; and a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising: receiving, by the controller, at least one shock strut parameter of a shock strut configured for mechanical coupling to a wheel assembly, the at least one shock strut parameter including at least a temperature of a gas and at least one shock strut design parameter; calculating, by the controller, a dead volume of a shock strut based upon the at least one shock strut parameter; and determining, by the controller, a first decision, the first decision being a Boolean value based upon whether the dead volume of the shock strut is negative; sending, by the controller, a weight-on-wheel prompt to the display, wherein the weight-on-wheel prompt is sent in response to the first decision being true, the weight-on-wheel prompt calls for an operator to indicate whether a shock strut servicing will be performed under weight-on-wheel conditions; receiving, by the controller, a weight-on-wheel decision based upon the weight-on-wheel prompt; activating, by the controller, a first shock strut servicing assistance system in response to the weight-on-wheel decision being true; and activating, by the controller, a second shock strut servicing assistance system in response to the weight-on-wheel decision being false. 2. The shock strut servicing assistance system of claim 1 , wherein the at least one shock strut design parameter is received from a memory. 3. The shock strut servicing assistance system of claim 1 , wherein the temperature of the gas is received from a temperature sensor.
