English term or phrase:Wide range of Pilot control pressure
Optimised matching between joystick and M.C.V.
(Wide range of Pilot control pressure )
Large variation possible dans la pression appliquée par le pilote
Explanation: Après queqlues recherches, je crois comprendre que MCV veut dire 'mine clearing vehicle' ou 'mobile construction vehicle'. Est-ce exact ?
En fait, comme le véhicule doit certainement être piloté par différentes personnes, et que ces différents pilotes ne conduisent certainement pas de manière identique, il faut que le joystick reconnaisse les variations dans la pression appliquée, plutôt que le niveau de pression lui-même, pour ensuite le répercuter dans les signaux transmis au joystick.
J'espère avoir été claire (!)
"During mine clearing, the vehicle can be operated using a joystick or through the use of a computerized fully automatic pilot steering system. When being used in the latter configuration, the operator needs only to select a number of key parameters, for example depth, on the monitor. The depth control of the flail and the armored deflector plate, which is positioned to the immediate rear of the rotating flail, is then fully automatic using sensors. The chains rotate clockwise if mines are buried and anti clockwise if they are on the surface. The mine clearing part consists of a rotating axle to which are attached 72 chains; the end of each of these is fitted with a hammer type head which weighs 0.9kg. When these chains or heads are damaged, they can be easily and quickly replaced The axle rotates at up to 400rpm, with the speed depending on the nature of the terrain. Mine clearing speeds depend on a number of factors. On cross-country terrain, for example, it is about 1.4 km/in while on a firm hard surface it could be up to 12km/h. Standard equipment for the Hydrema 910 MCV includes a 210 liter water tank and high pressure cleaning system; options include a Global Positioning System (GPS). As the system may be required for operations in any part of the world, it is fully air portable in a Lockheed Martin C-130 Hercules transport aircraft without preparation, and can be ready to use within 2 minutes."
