Momentum Thrust Solution

STEP 0: Pre-Calculation Summary
Formula Used
Ideal Thrust = Mass Flow Rate*((1+Fuel Air Ratio)*Exit Velocity-Flight Speed)
Tideal = ma*((1+f)*Ve-V)
This formula uses 5 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.
Fuel Air Ratio - Fuel air ratio is the ratio of mass flow rate of fuel to the mass flow rate of air.
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.
STEP 1: Convert Input(s) to Base Unit
Mass Flow Rate: 3.5 Kilogram per Second --> 3.5 Kilogram per Second No Conversion Required
Fuel Air Ratio: 0.009 --> No Conversion Required
Exit Velocity: 248 Meter per Second --> 248 Meter per Second No Conversion Required
Flight Speed: 111 Meter per Second --> 111 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Tideal = ma*((1+f)*Ve-V) --> 3.5*((1+0.009)*248-111)
Evaluating ... ...
Tideal = 487.312
STEP 3: Convert Result to Output's Unit
487.312 Newton --> No Conversion Required
FINAL ANSWER
487.312 Newton <-- Ideal Thrust

What is thrust?

Thrust is the force which moves an aircraft through the air. Thrust is used to overcome the drag of an airplane, and to overcome the weight of a rocket.

How to Calculate Momentum Thrust?

Momentum Thrust calculator uses Ideal Thrust = Mass Flow Rate*((1+Fuel Air Ratio)*Exit Velocity-Flight Speed) to calculate the Ideal Thrust, Momentum Thrust formula is defined as the thrust produced due to change in momentum of the aircraft, discarding the thrust produced due to pressure. Ideal Thrust is denoted by Tideal symbol.
