Method of managing a ground connection of an aircraft
View Patent ↗A method of managing a ground connection of an aircraft having landing gear with wheels that are subjected to static loads, some of which wheels are fitted with respective braking devices and others are fitted with respective independent drive devices, the method including the step of causing a modification to a distribution of the static loading to which the wheels of the landing gear are subjected in such a manner as to: increase the loading on at least some wheels fitted with respective braking devices, during a braking stage; and increase the loading on at least some wheels fitted with respective independent drive devices, during an independent drive stage.
1. A method of managing a ground connection and improving the braking capacity of an aircraft having landing gear with wheels that are subjected to static loads, some of which wheels are fitted with respective braking devices and others are fitted with respective independent drive devices, wherein the method comprises:
causing a modification to a distribution of the static loading to which the wheels of the landing gear are subjected in such a manner as to:
increase the loading on at least some wheels fitted with respective braking devices, during braking stages; and
increase the loading on at least some wheels fitted with respective independent drive devices, during independent drive stages.
2. A method according to claim 1 , applied to an aircraft in which the wheels fitted with braking devices are carried by a first group of undercarriages while the wheels fitted with independent drive devices are carried by a second group of undercarriages, wherein extra loading is applied to the wheels of one or the other of the groups of undercarriages by modifying at least one operating parameter of the shock absorbers of the undercarriages of at least one of the groups of undercarriages.
3. A method according to claim 2 , wherein, during braking stages, at least one functional parameter of the shock absorbers of the group of undercarriages having wheels that are fitted with independent drive devices is modified in order to reduce a stiffness of said shock absorbers, whereas during independent drive stages, at least one operating parameter of the shock absorbers of the group of undercarriages having wheels fitted with braking devices is modified in order to reduce a stiffness of said shock absorbers.
4. A method according to claim 1 , applied to an aircraft where the wheels fitted with braking devices are carried by a first group of undercarriages while the wheels fitted with independent drive devices are carried by a second group of undercarriages, wherein the undercarriages of both groups include kneeling devices, and wherein extra loading is applied to the wheels of one or the other of the groups of undercarriages by operating the kneeling devices of the undercarriages of at least one of the groups of undercarriages.
