Feasibility of Rapid Prototyping Manufacturing of Multi-Probe for Measuring Total Pressures at High Temperatures = Viabilidad de la Fabricación por Prototipado Rápido de una Multisonda para la Medida de Presiones Totales a Altas Temperaturas

Abstract

The variation in total pressure along the turbine engine is essential both to determine its efficiency to understand its operation. Due to rising temperatures in the combustion chamber and turbine aircraft engines latest generation of the development of probes capable of withstanding the high temperatures of these is necessary. Designing a multiprobe by laser sintering is novel by reduced meter size, choosing its shape, and manufacturing it from a single piece. 7 sensors are placed on a given turbine at various radial and circumferential positions to find the flow pressure profile section in position. It has demonstrated the technical feasibility, as theoretically design meets the structural and heat transfer conditions, and thus has been validated as microstructural dimensional model. Considering the economic viability of the proposed alternative method of manufacture is not so obvious, if the costs of manufacturing processes are considered. Keywords?
