Aeronautical Engineering

Hello Barani!
The following are the courses in aeronautical engineering:
Radar cross-section - the study of vehicle signature apparent to Radar remote sensing
Fluid mechanics - the study of fluid flow around objects.
Aerodynamics concerning the flow of air over bodies such as wings or through objects such as wind tunnels.
Astrodynamics - the study of orbital mechanics including prediction of orbital elements when given a select few variables.
Statics and Dynamics (engineering mechanics) - the study of movement, forces, moments in mechanical systems.
Mathematics - in particular, calculus, differential equations, and linear algebra.
Electrotechnology - the study of electronics within engineering.
Control engineering - the study of mathematical modeling of the dynamic behavior of systems and designing them.
Aircraft structures - design of the physical configuration of the craft to withstand the forces encountered during flight. Aerospace engineering aims to keep structures lightweight and low-cost.
Materials Science - related to structures, aerospace engineering also studies the materials of which the aerospace structures are to be built.
Solid mechanics - Closely related to material Science is solid mechanics which deals with stress and strain analysis of the components of the vehicle.
Aeroelasticity - the interaction of aerodynamic forces and structural flexibility, potentially causing flutter, divergence, etc.
Avionics - the design and programming of computer systems on board an aircraft or spacecraft and the simulation of systems.
Software - the specification, design, development, test, and implementation of computer software for aerospace applications, including flight software, ground control software, test & evaluation software, etc.
Risk and reliability - the study of risk and reliability assessment techniques and the mathematics involved in the quantitative methods. Noise control the study of the mechanics of sound transfer.
Aeroacoustics - the study of noise generation via either turbulent fluid motion or aerodynamic forces interacting with surfaces.
Flight test - designing and executing flight test programs in order to gather and analyze performance and handling qualities data in order to determine if an aircraft meets its design and performance goals and certification requirements
All the best!

As an Aerospace Engineer, it is utmost crucial to decide your interest whether you would be interested in Aeronautical Engineering or Astronautical Engineering. Both the branches have excellent job opportunities.
Job opportunities for these engineers are available in Airlines, Air Force, Corporate Research Companies, Defence Ministry, Helicopter Companies, Aviation Companies, NASA and many others.
Increasing popularity of air travel and space exploration require expertise to design and maintain improvements. Looking at heightening growth rate, the demand for smart and create Aerospace Engineers is only going to increase in the near future.
Some of the top recruiters in this space are Hindustan Aeronautics Limited (HAL), Defense Research and Development Laboratories (DRDO), Indian Space Research Organization (ISRO), Civil Aviation Department, Air India, India Space Research Organization (ISRO) and others.
