Aerospace Engineering

Here are some steps to approach
Make sure you have a tailored resume and good project idea*
There are a lot of divisions in NAL, find the one which is relevant to your project idea and get the contact details of the HOD. Email the HOD about your project idea and ask for a possible face to face meeting for further discussion. Based on the reply, meet up and convince that the project idea is helpful for NAL and that will fetch you the internship. *If you don't have any project idea, look up for the current projects of your interested division in NAL and you can come up with an idea based on those projects. I did my intern at NAL in MAV unit in summer 2015, the project idea involved wind tunnel testing, so my friend and I searched for the projects and found a common one and emailed the HOD, MET with the scientists and got the internship. The internship experience was very good.

Steps:
Make sure you have the latest or most impressive resume and a good project idea. There are a lot of divisions in National Aerospace Laboratories, find the one which is relevant to your project idea and get the contact details of the Head of the Department. Email the Head of the Department (HOD) about your project idea and ask for a possible face-to-face meeting for further discussion. Based on the reply, meet up and convince them that the project idea is helpful for National Aerospace Laboratories and that will fetch you the internship. If you don't have any project ideas, look up the current projects of your interesting division in National Aerospace Laboratories and you can come up with an idea based on those projects.

Getting an internship in the aerospace sector like Indian Space Research Organisation can be a cumbersome process, especially if you do not have any relatives working there. Aerospace is a vast area, and private Indian industry exists to support government projects in space and defense primarily. A few companies or organizations where you could look for Aerospace engineering internships are Hindustan Aeronautics Limited (HAL), National Aerospace Laboratories (NAL), and Aeronautical Development Agency (ADA) for aircraft and UAVs projects; Indian Space Research Organisation centers like SDSC, VSSC, and LPSC for launch vehicle engineering work; Honeywell Aerospace, GTRE, Airbus or Cassidian center, GE for Turbomachinery JET engines mainly) and structural analysis projects; Godrej & Boyce, Tata aerospace, DAL, Taneja Aerospace, and L&T for manufacturing of aerospace components and parts; Dhruva Space, TeamIndus, Ideaforge tech, Aniara communications, and Earth to orbit if you are looking for some 'Newspace' opportunities. I hope this will help you.
