Abstract
A method of making a multi-vane model for a nozzle guide out of sacrificial material, includes the steps of fabricating a single-vane model out of sacrificial material, assembling at least two sacrificial material single-vane models with each other, and positioning (104, 108) a holder element on at least one sacrificial material single-vane model so as to hold a predetermined spacing between an inner platform and an outer platform. An assembly of a sacrificial material single-vane model for a nozzle guide together with a holder element, and also an assembly of a sacrificial material multi-vane model for a nozzle guide together with a holder element.
