ANALISIS NOSEL BAHAN TUNGSTEN DIAMETER 200 mm HASIL PROSES PEMBENTUKAN

Abstract

Nosel rocket is which during the time made by LAPAN, using carbon steel which cannot arrest; detain high temperature so that thick made structure enough heavy and, to lighten structure used by tungsten materials that is materials which hold up high temperature, this materials [is] made with forming process that is pipe having size measure according to throat is later; then formed to become nosel, result of this forming
is analysed by its strength at various force pressure, analyse to temperature do not be done/conducted by because tungsten material have held up to temperature, result of
analysis indicate that thickly of thick tungsten materials 3 mm only holding up to maximum force 3000 kgf
