The Diploma in Aerospace Engineering normally lasts 3 years. The course is divided into 6 semesters each semester lasting about six months.
Yes the duration may vary slightly depending on your entry qualification. If you join right after class 10th the course is full 3 years. But in some colleges if you have completed class 12th with PCM (Physics Chemistry Mathematics) you may get lateral entry into the second year so total duration becomes around 2 years.
Over the 3-year period students acquire both theoretical knowledge and practical skills. They study subjects like aircraft structures avionics aerodynamics aircraft maintenance materials science jet engine theory and get lab based training in electrical systems workshop practice aircraft servicing and more.
This ensures that after completing the diploma a student knows how aircraft and spacecraft are designed manufactured tested and maintained
After completing the 3-year diploma you can directly look for jobs in aerospace industry aviation maintenance or related areas or you can continue higher studies. Many students take admission in B.Tech in Aerospace Engineering (often via lateral entry) to deepen their knowledge.
Yes if you have completed class 10th and want to start a career in aerospace early this diploma makes sense. You get qualified in 3 years and can start working or build further studies. If you come after class 12th with PCM you might finish in 2 years and join the industry early.
