Transmission assembly for an aircraft capable of hovering, comprising: a first and a second member and support means of the first member with respect to the second member; a primary lubrication circuit comprising a primary tank of a lubricating fluid and primary fluidic supply means for supplying fluid to the support means; and an emergency lubrication circuit comprising an emergency tank of lubricating fluid fluidically connected to the primary tank; and auxiliary fluidic supply means of the lubricating fluid to the support means, comprising a nozzle; the auxiliary fluidic supply means comprise a dosing device and a fluidic line, which fluidically connects the emergency tank with the dosing device; the dosing device comprising a passage for the lubricating fluid from the fluidic line to the nozzle, which comprises a plurality of concentrated pressure drop sections, which are distinct and spaced apart from each other.

Transmission assembly for an aircraft capable of hovering

A method for controlling an aircraft capable of hovering is described, comprising a first engine; a second engine; at least one rotor; and a transmission interposed between the first and second engine and the rotor; the transmission comprises a first and a second inlet connected respectively to a first outlet member of the first engine and to a second outlet member of the second engine; the method comprises step i) of placing the in a first configuration, in which the first and second engine make available a first and a second power value; or in a second configuration, in which the first engine makes available a third power value greater than the first power value to the first inlet, and the second engine delivers a nil power value to the second inlet; the method also comprises, characterised in that it comprises the steps of ii) detecting a series of parameters associated with the operating conditions of the aircraft; and iii) enabling the transition of the aircraft from the first configuration to the second configuration, when the parameters assume respective first values.
