Specific Thrust
Specific Thrust is a way to measure how efficient an aircraft engine is at producing power. Think of it like measuring a car's fuel efficiency, but for aircraft engines. It tells us how much pushing force (thrust) an engine can create compared to how much air it needs to do so. This is important because employers want engineers who can help make engines that are more powerful while using less fuel. When you see this term in resumes, it often indicates that the candidate has experience with engine performance analysis and improvement.
