Abstract
A shock strut servicing assistance system may comprise a controller including a display, and a tangible, non-transitory memory configured to communicate with the controller. The tangible, non-transitory memory may have instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising calculating, by the controller, a first fluid level, generating, by the controller, a first datum corresponding to the first fluid level, receiving, by the shock strut, a fluid in response to the first datum, calculating, by the controller, a second fluid level, generating, by the controller, a second datum, and storing, by the controller, a final fluid level.
Claims15
A method for monitoring a shock strut including:
- adjusting, by a controller, at least one of an oil volume and a gas pressure, wherein adjusting the oil volume comprises calculating a normalized oil volume, and adjusting the gas pressure comprises calculating a normalized gas pressure;
- detecting, by the controller, at least one of an oil volume loss and a gas number of moles loss, wherein detecting the oil volume loss comprises calculating a difference between a desired oil volume and the normalized oil volume, and detecting the gas number of moles loss comprises calculating a normalized gas number of moles using the normalized gas pressure and calculating a difference between a desired gas number of moles and the normalized gas number of moles;
- determining, by the controller, if the at least one of the oil volume loss and the gas number of moles loss is above a second threshold;
- determining, by the controller, if the at least one of the oil volume loss and the gas number of moles loss is above a first threshold, in response to the at least one of the oil volume loss and the gas number of moles loss not being above the second threshold;
- generating, by the controller, a signal corresponding to determination of the at least one of the oil volume loss and the gas number of moles loss being one of:
- above the second threshold, not above the second threshold but above the first threshold, or not above the first threshold;
- displaying a warning signal based upon the signal;
- and
- servicing the shock strut in response to the warning signal;
- wherein the detecting, by the controller, at least one of the oil volume loss and the gas number of moles loss comprises detecting, by the controller, the gas number of moles loss.
