| 摘要 |
The drum of the invention is generally in the form of a body of revolution about a longitudinal axis, being made of a metal alloy and extending between an upstream end and a downstream end along a curved profile capable of being circumscribed in an annular envelope extending around said longitudinal axis, said profile extending radially about a surface of revolution presenting a generatrix line, said downstream end being provided with a stiffener. In characteristic manner, said stiffener is provided with at least one composite assembly mounted on said downstream end, said composite assembly comprising fibers and a polymer matrix. The drum is preferably for use in constituting a rotor of a low pressure compressor.
