Propulsion
Propulsion refers to the systems and methods used to move aircraft, spacecraft, or rockets through air or space. In simple terms, it's the science of making things fly or move forward using different types of engines and fuel systems. When you see this term in resumes, it usually means the candidate has worked with aircraft engines, rocket engines, or related systems. Think of it like the automotive industry's focus on car engines, but for flying vehicles. Common types include jet engines, rocket engines, and traditional aircraft engines.
Examples in Resumes
Designed and tested Propulsion systems for commercial aircraft engines
Led a team of 5 engineers in Propulsion System development for satellite thrusters
Optimized Propulsion efficiency resulting in 15% fuel savings in new engine design
