INSTALLATION FOR FABRICATING A THERMAL PROTECTION COVERING OF A BODY OR OF A REAR ASSEMBLY FOR A THRUSTER, AND ASSOCIATED METHODS

摘要

An installation for fabricating a thermal protection covering of a body or of a rear assembly for a thruster, includes an extruder presenting a die having an outlet orifice through which a strip of elastomer material is to be extruded, the extruder having a die control system to vary the size of the outlet orifice; a mandrel to be set into rotation about its axis; a deposition head to deposit the strip on the mandrel; a conveyor system to convey the strip from the outlet orifice of the die of the deposition head; and a thickness monitoring system to measure the thickness of the strip on the deposition head and on the mandrel and to compare each measured thickness value with a predetermined value, the thickness monitoring system to control the die control system so as to cause the size of the outlet orifice of the die to vary.

1. An installation for fabricating a thermal protection covering of a body or of a rear assembly for a thruster, said installation comprising:
an extruder presenting a die having an outlet orifice through which a strip of elastomer material is to be extruded, the extruder being provided with a die control system configured to vary the size of the outlet orifice of the die; a mandrel configured to be set into rotation about its axis; a deposition head configured to deposit the strip on the mandrel, the deposition head and the mandrel being configured to be set into movement relative to each other along the longitudinal axis of the mandrel; a conveyor system configured to convey the strip from the outlet orifice of the die to the deposition head; and a thickness monitoring system configured to measure the thickness of the strip on the deposition head and on the mandrel and to compare each measured thickness value with a predetermined value, said thickness monitoring system also being configured, as a function of the result of such comparisons, to control the die control system so as to cause the size of the outlet orifice of the die to vary.
