Formula Used

Ideal Thrust = Mass Flow Rate*(Exit Velocity-Flight Speed)
T_ideal = m_a*(V_e-V)
This formula uses 4 Variables

Variables Used

Ideal Thrust - (Measured in Newton) - Ideal Thrust is the thrust produced by an engine when nozzle exit pressure is same as ambient pressure or nozzle is perfectly expanded.
Mass Flow Rate - (Measured in Kilogram per Second) - Mass Flow Rate represents the amount of mass passing through a system per unit of time.
Exit Velocity - (Measured in Meter per Second) - Exit Velocity refers to the speed at which gases expand at the exit of nozzle of a engine.
Flight Speed - (Measured in Meter per Second) - Flight Speed refers to the velocity at which an aircraft moves through the air.

what is thrust?

Thrust is a mechanical force. It is generated most often through the reaction of accelerating a mass of gas. The engine does work on the gas and as the gas is accelerated to the rear, the engine is accelerated in the opposite direction. The acceleration of the engine mass produces a force on the aircraft.

How to Calculate Ideal Thrust of Jet Engine?

Ideal Thrust of Jet Engine calculator uses Ideal Thrust = Mass Flow Rate*(Exit Velocity-Flight Speed) to calculate the Ideal Thrust, Ideal Thrust of Jet Engine formula is defined as a simplified concept to include post-exit thrust is to assume a hypothetical uniform jet with velocity after expansion. Another simplification is to ignore the fuel mass flow rate relative to the air mass flow. Ideal Thrust is denoted by T_ideal symbol.

How to calculate Ideal Thrust of Jet Engine using this online calculator? To use this online calculator for Ideal Thrust of Jet Engine, enter Mass Flow Rate (m_a), Exit Velocity (V_e) & Flight Speed (V) and hit the calculate button. Here is how the Ideal Thrust of Jet Engine calculation can be explained with given input values -> 479.5 = 3.5*(248-111).
