What does a propulsion engineer do?
Propulsion engineers design, test, and manufacture spacecraft propulsion systems, using scientific and engineering knowledge. Propulsion engineering is a speciality within aerospace engineering. Exploring the Four Primary Areas of Engineering: Types and Salaries. Engineering professions typically fall under four different types: chemical, civil, electrical and mechanical engineering.Historically, engineering was grouped into four main disciplines: civil, chemical, mechanical and electrical. As modern technology has advanced, aeronautical/aerospace engineering and computer engineering have become new fields in their own right. This in-depth guide will break down the six fields of engineering.
