In those four years you study basic sciences and engineering in the first year physics chemistry mathematics programming basic electrical and electronics materials science. From the second year onwards you begin core aerospace topics such as thermodynamics fluid mechanics heat transfer aerodynamics machine elements solid mechanics and strength of materials. In the later years you dive deeper compressible flow atmospheric & space flight mechanics propulsion systems aerospace structures flight mechanics control systems vehicle design rocket propulsion labs and project work. By the end of 4 years you have a broad knowledge of aerodynamics propulsion structures avionics aircraft/space vehicle design and hands-on lab experience.
These colleges offer full 4-year B.Tech/B.E courses in Aerospace Engineering.
Infrastructure is often strong: labs workshops (sometimes even aircraft maintenance hangars), research facilities, good libraries and simulation tools.
Course covers wide range of useful topics - aerodynamics propulsion fluid & structural mechanics control systems design giving you a good foundation for aerospace or aviation careers.
Fees tend to be more reasonable compared to big metro city colleges (many institutions in Guntur offer education at lower cost).
Given India's growing aerospace and space sector graduates have opportunities for aircraft design, manufacturing avionics testing maintenance research or work with airlines space / defence organisations.
Not all lists show many colleges strictly offering Aerospace Engineering the list under Aerospace Engineering Colleges in Guntur" from source seems to include colleges outside Guntur too.
Because supply of aerospace specialised colleges may be limited competition for admission (via entrance exams) could be higher.
As with many engineering courses you'll need strong foundation in PCM (physics chemistry maths) if you join from 12th PCM background you'll be fine otherwise it may be tough.
