The three-point hitch coupler systems constitute a special method of implement mounting. The hitch couplers are an additional component located between the three-point…
Agricultural wheeled tractors and implements — Three-point hitch couplers — Part 3: Link coupler
Specifies the essential dimensions for the attachment of three-point hitch implements to agricultural wheeled tractors equipped with a three-point free link hitch according to ISO 730-1 or ISO 8759-2, and a set of link couplers. The three-point hitch coupler systems constitute a special method of implement mounting. The hitch couplers are an additional component located between the three-point…
Flight dynamics — Concepts, quantities and symbols — Part 9: Models of atmospheric motions along the...
Deals with the concepts and quantities characterizing models of the air motions affecting the dynamic behaviour of the aircraft. The motion of the air with respect to the Earth is defined by the wind velocity in each point of the aircraft trajectory. In flight dynamic problems, it is usual to use mathematical models of the wind velocity field and its variation with time. The following models are…
