GATE Syllabus of Aerospace Engineering4:27 pm
GATE Syllabus of Aerospace Engineering. GATE (Graduate Aptitude Test for Engineering) is one of the toughest engineering test, an all India Examination that basically tests the comprehensive understanding of various undergraduate subjects in Engineering and Technology. It has been known for testing the engineering basics in a smart way.It needs a lot of effort to excel in this exam. In Gate 2017, the total five states that had qualified candidates are Andhra Pradesh (22,476), Uttar Pradesh (22,400), Maharashtra (9,951), Bihar (9,820)& Kerala (8,992)
Aerospace Engineering is popular among those who wants to pursue their career into air planes,jumbo jets,space shuttles and other similar stuffs.It deals with all the technical details and mechanisms of all flying bodies. Aeronautical engineers are needed in Aircraft manufacturing units, space stations etc. It helps a person to gain knowledge on complex design and development of high flying machines. It also deals with radars, navigation systems and other communication systems. Qualified Technical engineers are needed to maintain and develop the growing fleet of aircraft as each day new air routes are being added to the airline Industry. Aeronautical engineers can find jobs in Aviation industry, Satellite and Space Research organizations,Defence, Automobile and fast moving locomotive Industries. This field has lots of demand and one have to face a lot of challenges. A student must have a strong mathematical base along with creative and analytic mind
