The invention discloses an upper beam, a helicopter airframe adopting the upper beam and a helicopter. The upper beam is a U-shaped component formed by two straight rod parts which are parallel to each other and a bridge joint part for connecting one ends of the two straight rod parts. The airframe is of a damping structure formed by mutual connection of an upper frame and a tripod through an engine assembly and a damper, the upper frame is of a rigid structure formed by the upper beam, a front beam, an upper bearing beam, supporting rods and a tail pipe through two pairs of middle beams with five connecting supporting arms, and three of the supporting rods are connected with three of the middle beams. A gearbox is positioned on the upper bearing beam. The airframe has the beneficial effects of being simple in structure, easy to manufacture, cost-saving, light in weight, good in rigidity, excellent in damping performance, easy for disassembling, assembling and maintenance, and the like.
