ABSTRACT:
An elongated, rigid boom for the in-flight refueling of rotary wing aircraft in which a forward end of the boom is adapted for attachment to the fuselage of a rotary wing tanker aircraft and is of sufficient length to extend rearwardly of the tanker aircraft for the rear end of the boom to be clear of the tanker aircraft rotor path. The forward end of a funnel refueling drogue configured to receive the fueling probe of an aircraft to be refueled is swivelly attached to the rear end of the rigid boom and a fuel line supported by the boom extends from a connection into the tanker aircraft refueling tanks to a female refueling aircraft probe connection in the drogue. Pressurized air flowing within the boom is discharged from a downwardly directed nozzle and selectively from outwardly facing nozzles on each side of the boom adjacent the boom rear end with the nozzles being configured to establish a volume rate discharge as creates a vertical lifting force on the boom compensating for gravity and rotor downwash and boom side forces selectively directed horizontally outwardly in either direction for establishing yaw control of the boom.
