GATE Syllabus for Aerospace Engineering 2020 with Pattern

Last Updated on April 25, 2020 by ePostbag

IIT Delhi conducts GATE 2020 for 24 different papers. Here in this post let us talk about the GATE Aerospace syllabus for this academic year. Aerospace Engineering (AE) is one of the GATE 2020 papers in which huge of candidates appear. Along with the subjects of the AE, candidates will also have to prepare the General Aptitude (GA) which is common in all the papers. This section will cover 10 questions and the remaining 55 questions out of 65 are subject based.

GATE Aerospace Engineering Syllabus

Aerospace Engineering is one of the primary fields of Engineering. AE is associated with the development of spacecraft and aircraft. Candidates who are going to appear in the GATE AE paper will have to check the GATE 2020 Aerospace syllabus to know all the topics so that one can prepare better and score good marks.

The syllabus for Aerospace Engineering (AE) will have the subjects that are divided in to two categories and they are core topics and special topics. However, 90% of the questions will be covered from the core topics and the remaining 10% questions will be asked from the special topics. AE have six different sections or subjects which includes both core topics and special topics. The subjects that are covered under AE are Engineering Mathematics, Flight Mechanics, Space Dynamics, Aerodynamics, Structures and Propulsion. Check the detailed GATE Aerospace Engineering syllabus from the below given tabular form.

GATE Aerospace Syllabus and Pattern 2020

  • AE paper syllabus consists of total 6 sections.
  • Each section is divided in to two categories – Core topics and Special topics.
  • AE paper will have 25 questions that carry 1 mark each i.e., 25 Marks in total and 30 questions that carry 2 marks each i.e., 60 Marks in total.
  • GATE 2020 for AE is conducted in online mode.
  • AE paper contains MCQ (multiple choice questions) and NAT (Numerical Answer Type) type questions.
  • For every incorrect answer in the MCQs, there will be negative marking.
  • For incorrect answered questions in the NATs, there is no negative mark.
