hi whether srm or amrita is best for aerospace engineering

Well I can share the details of Lovely professional university which is in Punjab based on which you can make an analysis that what are the positive factors that should be considered while looking for a university or college.

LPU is a well renowned university, providing quality education, innovative pedagogy and unbeatable placements both national and international. LPU provides a great academic exposure to its students. It provides a chance to the students to attend guest lectures or workshops, so that they get to learn as much as they can. The students also work on live projects, so that they are able to apply their knowledge to practical settings. It is one of the few that has embraced international practices when it comes to designing a curriculum.

LPU provides ample opportunities to each and every eligible student of lpu to secure a good placement. Every year more than 550 companies visit lpu for recruitment purpose. Companies which recruit from IIT's and IIM’s also land at lpu for recruitment purpose. Lpu has made professional enhancement classes as an integral part of the curriculum which helps students in their growth. LPU is also conferred with National Employ ability Award 2020 by Aspiring Minds for the 7th time in a row for having Most Employable Students and being one among the top colleges and universities in India with one of the highest Employ ability rates. In lpu student practice on live models and this programme is designed for learners intend to design aircraft, spacecraft, satellites and missiles. In addition, these engineers test prototypes to make sure that they function according to plans. These professionals also design components and sub-assemblies for these craft like engines, air-frames, wings.

Hello!

Aerospace is a niche area, the skills required in industry are beyond the course curriculum of most of the universities. LPU has recognised this and developed the curriculum in consultation with the industry. It has even set up center for space research with mission control facility. https://www.lpu.in/FullNewsRelease/LPU-sets-up-Center-for-Space-Research-with-Mission-Control-facility.php
LPU has set an ambitious goal of developing a satellite LPUSAT-1, which will be launched next year (2021)
The Center will enable students and researchers to communicate with the International Space Station (ISS), download live satellite images, and receive telemetry, Science/engineering data from nano-satellites and larger spacecrafts
The Center will act as a key facility in the field of space research for LPU as well as a virtual lab for Universities, Colleges and Schools in India and the neighboring countries of India
A team of students, Visionauts, from Lovely Professional University have won the prestigious STEM Engagement Award in the 2019 NASAs Human Exploration Rover Challenge held at the US Space & Rocket Center in Huntsville, Alabama. This marks the third consecutive occasion of a team from LPU getting selected to participate in the prestigious competition. Interestingly, the team also got an opportunity to interact with Sunita Williams, NASA astronaut and two-time spaceflight veteran, who attended the second day of the event. https://www.lpu.in/FullNewsRelease/History-Created-LPU-Students-won-the-NASA-Award-in-USA.php
Here is a brief Idea at what level LPU operates !
It is definitely the top educator in field of aerospace.

I Hope this helps.

All the Best!

As both are the good options but if you getting chance to get admission in SRM main campus then you should go for that. But also consider your interest, choice and convenience before making any decision. And to make it more clear you can check rating and reviews through given below links -

SRM University, Chennai

Amrita School of Engineering, Coimbatore

Hope this helps!!!
