Abstract
A method for pressurizing and depressurizing a shock absorber of an aircraft. More specifically, it relates to a method in which an aircraft weight and ambient temperature are used to calculate a required pressurization level of a shock absorber. As such, the shock absorber may be pressurized to the correct level without applying an iterative approach, greatly reducing initialization time.
Claims12
A method of pressurising or depressurising an aircraft shock absorber, the method comprising:
- determining the weight of the aircraft based upon an internal pressure of the aircraft shock absorber;
- measuring an ambient temperature around the shock absorber;
- calculating a target length of the shock absorber based on the ambient temperature and the determined weight of the aircraft;
- and
- pressurising or depressurising the shock absorber to the target length.
2 more elements
A system for pressurising or depressurising a shock absorber of an aircraft, the system comprising:
- pressurisation means, in fluid connection with the shock absorber;
- a temperature sensor, arranged to measure an ambient temperature around the system;
- and
- control logic, arranged to control the pressurisation means,
- wherein the control logic comprises a processor arranged to:
- determine the weight of the aircraft based upon an internal pressure of the aircraft shock absorber;
- receive an ambient temperature measurement from the temperature sensor;
- calculate a target shock absorber length based on the temperature measurement and the determined weight of the aircraft;
- and
- instruct the pressurisation means to pressurise or depressurise the shock absorber to the target length.
