Development of a Small Jet Engine Test System for University Education IGTC2003Tokyo TS-113

Abstract

ABSTRACT For an effective understanding of the characteristics of gasturbine engines and of jet engines, a project is made to develop a small jet engine test system by university students. A commercial turbo-charger for automotive use is employed and a combustor and nozzles are designed to match it. Auxiliary components such as fuel or lubricant or cooling water supplies are also selected for operation. Diagnosis system to monitor the operating conditions is designed. Most of these components are mass production parts for automobiles that meet the educational requirement of low-cost and heavy-duty. The first firing was achieved in the first year of the project. By improving components performance and matching, the engine achieved the maximum thrust of 42 N at an engine speed of 170,000 rpm and efficiency of 8 % at 160,000 rpm, finally
