Exercise 4: Turbojet Engine Performance

Objective : What I want you to learn?

  • To apply the thermodynamic equations and analyse the performance of a Turbojet Engine with variation in the Speed and Altitude

Rationale : Why this is useful to you?

  • An Engine is a source of power for an aircraft, to evaluate the aircraft performance we need to evaluate the engine performance first.

Learning Outcomes : What I want you to do after completing this topic?

  • Apply the thermodynamic equations to analyse the performance of a Turbojet Engine using the Python Code.

  • Generate the Plots of Variation of Jet Engine Performance with Altitude and Velocity.

Assignment 4:

  1. An airplane powered with the turbojet engine with the Inlet diameter is 0.75 m flying at standard sea level with a velocity of 305 m/s with the fuel-air ratio 0.05. (Use the Data Given Below)

  1. Plot the Variation of Thrust Produced by the Engine Varying with the Velocity at the Altitude of 5 km from Mean Sea Level Under ISA.

  2. Plot the variation of Thrust Produced by varying the altitude at the Velocity of 305 m/s
