Overall Thrust of a SCRAMJET engine Calculator

The performance of a scramjet (supersonic combustion ramjet) engine is typically characterized by key parameters that assess its efficiency and effectiveness in generating thrust. Scramjet engines are designed for high-speed flight in the supersonic and hypersonic regimes. The performance of a scramjet engine can be evaluated using various metrics, including specific thrust, thermal efficiency, and overall thrust. Please note that scramjet engines are highly specialized and complex, and these simplified formulas may not capture all the nuances of their operation.

The overall thrust generated by a scramjet engine depends on factors such as air mass flow rate, combustion efficiency, and flight conditions.

Formula for thrust (T):

T=ṁ(VeV0)

Where:

  • T is the thrust generated by the engine (in Newtons, N).
  • ṁ is the air mass flow rate (in kilograms per second, kg/s).
  • Ve is the exhaust velocity of the engine (in meters per second, m/s).
  • V0 is the inlet velocity of the incoming air (in meters per second, m/s).
