Aerospace & Automotive Dictionary
Definition
A propulsion concept defining components, performance measures, and operating principles used to generate thrust in air or space systems. It governs energy conversion, mass flow, and control behaviors that determine efficiency and achievable mission performance. It does not ensure reliability without appropriate thermal and mechanical design margins and validated operating limits.
Thrust Specific Fuel Consumption
Engineering & Applied Technologies Dictionary
Definition
A measure of jet‑propulsion fuel efficiency defined as the rate of fuel mass flow consumed per unit of thrust produced, typically expressed as ṁ_fuel / T (e.g., kg·s−1 per N) or in conventional units like lb/(lbf·hr); it quantifies fuel mass required to generate a unit of steady thrust at a specified operating condition.
