STEP 0: Pre-Calculation Summary

Formula Used

Ram Drag of Turbojet = Gross Thrust of Turbojet-Net Thrust of Turbojet
D_ram = T_G-T
This formula uses 3 Variables

Variables Used

Ram Drag of Turbojet - (Measured in Newton) - Ram Drag of Turbojet refers to the drag force experienced by a turbojet engine due to the impact of air at high speeds.
Gross Thrust of Turbojet - (Measured in Newton) - Gross Thrust of Turbojet is the total thrust force produced by a turbojet excluding the ram drag.
Net Thrust of Turbojet - (Measured in Newton) - Net Thrust of Turbojet denotes the total thrust or forward force exerted by the engine to propel an aircraft forward.

STEP 1: Convert Input(s) to Base Unit

Gross Thrust of Turbojet: 1124 Newton --> 1124 Newton No Conversion Required
Net Thrust of Turbojet: 469 Newton --> 469 Newton No Conversion Required

Mass Flow Rate in Turbojet given Thrust

Go Mass Flow Rate Turbojet = (Net Thrust of Turbojet-Nozzle Exit Area*(Nozzle Exit Pressure-Ambient Pressure))/((Exit Velocity-Flight Speed)*(1+Fuel Air Ratio))

Exhaust Velocity given Thrust in Turbojet

Go Exit Velocity = (Net Thrust of Turbojet-Nozzle Exit Area*(Nozzle Exit Pressure-Ambient Pressure))/(Mass Flow Rate Turbojet*(1+Fuel Air Ratio))+Flight Speed

Flight Speed given Thrust in Turbojet

Go Flight Speed = Exit Velocity-(Net Thrust of Turbojet-Nozzle Exit Area*(Nozzle Exit Pressure-Ambient Pressure))/(Mass Flow Rate Turbojet*(1+Fuel Air Ratio))

Nozzle Exit Area in Turbojet

Go Nozzle Exit Area = (Net Thrust of Turbojet-Mass Flow Rate Turbojet*(1+Fuel Air Ratio)*(Exit Velocity-Flight Speed))/(Nozzle Exit Pressure-Ambient Pressure)

Net Thrust Produced by Turbojet

Go Net Thrust of Turbojet = Mass Flow Rate Turbojet*(1+Fuel Air Ratio)*(Exit Velocity-Flight Speed)+Nozzle Exit Area*(Nozzle Exit Pressure-Ambient Pressure)

Exhaust Velocity given Gross Thrust in Turbojet

Go Exit Velocity = (Gross Thrust of Turbojet-(Nozzle Exit Pressure-Ambient Pressure)*Nozzle Exit Area)/(Mass Flow Rate Turbojet*(1+Fuel Air Ratio))

Mass Flow Rate of Turbojet given Gross Thrust

Go Mass Flow Rate Turbojet = (Gross Thrust of Turbojet-(Nozzle Exit Pressure-Ambient Pressure)*Nozzle Exit Area)/((1+Fuel Air Ratio)*Exit Velocity)

Turbojet Gross Thrust

Go Gross Thrust of Turbojet = Mass Flow Rate Turbojet*(1+Fuel Air Ratio)*Exit Velocity+(Nozzle Exit Pressure-Ambient Pressure)*Nozzle Exit Area

Thermal efficiency of turbojet engine

Go Turbojet Thermal Efficiency = Propulsive Power/(Fuel Flow Rate*Fuel Calorific Value)

Net Thrust of Turbojet given Gross Thrust

Go Net Thrust of Turbojet = Gross Thrust of Turbojet-Ram Drag of Turbojet

Gross Thrust of Turbojet given Net Thrust

Go Gross Thrust of Turbojet = Net Thrust of Turbojet+Ram Drag of Turbojet

Ram Drag of Turbojet given Gross Thrust

Go Ram Drag of Turbojet = Gross Thrust of Turbojet-Net Thrust of Turbojet

Mass Flow Rate of Exhaust Gases

Go Mass Flow Rate Turbojet = Mass Flow Rate Turbojet+Fuel Flow Rate

Mass Flow Rate of Exhaust Gases given Fuel Air Ratio

Go Mass Flow Rate = Mass Flow Rate Turbojet*(1+Fuel Air Ratio)
