Sir,plz tell about aerospace engg in iiy kharagpur (dual degree programme)??

Aerospace comprises of bunch of branches like mechanical.. material design etc..You will have plenty of options to choose with mechanical as it is the wider branch unlike Aerospace. Scope of Aerospace is very much limited. Also do not think you will land up in NASA after taking aerospace. I tell you its very very different from that. With Aerospace you will have job opportunities in consultancy and finance section only. Also the scope of foreign interns with aerospace is very much limited
