Jet engine specially for model propulsion has a monolithic construction of turbine and compressor and fan

摘要

A jet engine, especially for propelling models, has a simplified design with a monolithic construction comprising compressor wheel, turbine wheel and fan, all mounted on common bearings. The system is lubricated via permanent ducts and a front mounted lubricant tank. Cooling airflow is ducted through a hollow axis and through coolant bores.
