B Tech Aerospace Engineering

B Tech Aerospace Engineering

B Tech Aerospace Engineering is a semi-specialized branch at graduate level in engineering discipline. Graduates in Aerospace Engineering discipline are expected to take up challenging work in the aerospace engineering industry – be it is a government organization or a private one. They are expected to work primarily on crucial aspects like propulsion systems, aerodynamic design, structural systems, precision manufacturing, etc. Main attractions in India are Indian Space Research Organization (ISRO), BARC, VSSC, etc. These are premier institutions in the country contributing into the national space programme. There are good careers for aerospace engineers, after B Tech Aerospace Engineering – that is outside ISRO, in entities like HAL, DRDOs, and ancillary industries connected with the aviation sector. As most of the B Tech Aerospace engineering curriculum cover most courses in Mechanical Engineering, a graduate in aerospace engineering can also take up jobs in the automotive sector, Power sector, Manufacturing sector, R&D organizations, etc.

B Tech Aerospace Engineering Programme Objectives:

  • Application and demonstration of knowledge by integrating mathematics, science, and engineering. This will include topics in aeronautical engineering, aerodynamics, materials in aerospace, structures, propulsion, flight mechanics, and stability
  • Evaluate, define, interpret and solve problems in the aerospace sector
  • Should be able to sketch, formulate, design & do experiments
  • Predict, calculate, analyze and evaluate / results data generated from the experiments – needless to state, Mathematics plays an important role in this regard.
  • An ability to understand, use modern engineering techniques learned in theory, skills, and computing tools necessary for aerospace industry and core engineering design practices.
  • Based on the needs, the graduate should be able to define, assess, understand, examine and design a process, system, model, component that may lead to further research and development
  • Considering the public health and safety, design system components or processes that meet the specified needs. This would also include cultural, societal, and environmental considerations.
  • Should be able to describe, explain and communicate and convey the ideas effectively with written, oral, and visual means.

  • Identify, formulate, research literature, and analyze complex engineering problems in the aviation sector, reach substantiated conclusions with focus in aerospace engineering.

A short note on B Tech Aerospace Engineering Education and Industry

After B Tech in Aerospace Engineering, the graduates are expected to work on the design and development, testing of aircraft, launch vehicles, and any type of space vehicle which may be built in future. Compared with the other traditional ground based systems and processes, optimality and reliability are of core importance in the aviation sector. This throws the light on the need for precise, theoretical and experimental analysis of a wide range of concepts, and performance / results predictions, its analysis of a range of complex systems in aviation sector. Aerospace Engineering is the discipline which is closest to what is widely known as “Rocket Science”.

Four broad, sub-disciplines identified under Aerospace Engineering

  1. Aerodynamics and Flight Mechanics
  2. Thermal and Propulsion
  3. Design and Structures
  4. Materials and Manufacturing

These areas are subject to change / increase the topics as the time goes because of the huge research and development that is happening in the aviation industry.

Some of the courses taught for B Tech Aerospace Engineering graduates are fundamental courses like Solid Mechanics, Fluid Mechanics, Thermodynamics, Heat Transfer and Materials Science, and applied courses like Aerodynamics, Gas Dynamics, Propulsion, Atmospheric and Spaceflight Mechanics, Theory of Machines, Aerospace Structures, and Manufacturing Processes.

Choosing Best College for B Tech Aerospace Engineering

Compared with any other engineering discipline, aerospace engineering department need to have several laboratories including instructional and research labs essential to carry out real time experiments for the growing aspirants in aerospace engineering. There is no need to mention that engineering education is incomplete without exposure to real life problems and issues. Without developing the ability to experimentally investigate the performance of actual systems, any engineering study is futile.  Following labs are essential for a successful career in B Tech Aerospace Engineering.
