Delhi Technological University (DTU) does not offer Aerospace Engineering but you can go for Mechanical Engineering which is worth and then specialised in Aerospace. The staff in DTU are great and almost everyone has done their PhDs in the mechanical Department. If you still looking for Aerospace Engineering, you can go to IIST aerospace engineering but it has limited jobs unlike mechanical engineering.
