Title:
DEVICE AND METHOD FOR CHECKING AN AIRCRAFT LANDING GEAR SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2013/178998
Kind Code:
A3
Abstract:
An electronic device checks the pressure of an aircraft landing gear oleo by means of a camera capturing and processing an image of the oleo. An image recognition module processes the oleo image to extract a measure of the amount of extension of the oleo. This measure is then processed together with a measure of oleo temperature to calculate a pressure value representative of the expected pressure of the gas within the oleo, which can then be compared with another measurement of oleo pressure to determine whether the two are consistent or whether the oleo might be under- or over-filled with gas. The electronic device may be in the form of a hand-held smart phone or tablet device appropriately programmed with software.
