GATE 2020Aerospace Engineering Syllabus

Aerospace Engineering Syllabus consists of 6 section. In each of the section divided into two categories – Core Topics and Special Topics. Check below Aerospace Engineering Syllabus in detail:

Section 1: Engineering Mathematics

Engineering mathematics is a branch of applied mathematics concerning mathematical methods and techniques that are typically used in engineering and industry. It is one of the difficult section of the paper. This section carries fifteen percentage weightage of the questions.

Core Topics

Core TopicsSub Topics
Linear AlgebraVector algebra, Matrix algebra, systems of linear equations, rank of a matrix, eigenvalues and eigenvectors.
CalculusFunctions of single variable, limits, continuity and differentiability, mean value theorem, chain rule, partial derivatives, maxima and minima, gradient, divergence and curl, directional derivatives. Integration, Line, surface and volume integrals. Theorems of Stokes, Gauss and Green.
Differential EquationsFirst order linear and nonlinear differential equations, higher order linear ODEs with constant coefficients. Partial differential equations and separation of variables methods.

Special Topics:

Fourier Series, Laplace Transforms, Numerical methods for linear and nonlinear algebraic, equations, Numerical integration and differentiation.

Section 2: Flight Mechanics

Flight mechanics are relevant to fixed wing (gliders, aeroplanes) and rotary wing (helicopters) aircraft. An Aeroplane (Airplane in US usage), is defined in ICAO Document 9110.  

Core Topics:

Core TopicsSub Topics
BasicsAtmosphere: Properties, standard atmosphere. Classification of aircraft. Airplane (fixed wing aircraft) configuration and various parts.
Airplane performancePressure altitude; equivalent, calibrated, indicated air speeds; Primary flight instruments: Altimeter, ASI, VSI, Turn-bank indicator. Drag polar; takeoff and landing; steady climb & descent, absolute and service ceiling; cruise, cruise climb, endurance or loiter; load factor, turning flight, V-n diagram; Winds: head, tail & cross winds
Static stabilityAngle of attack, sideslip; roll, pitch & yaw controls; longitudinal stick fixed & free stability, horizontal tail position and size; directional stability, vertical tail position and size; dihedral stability. Wing dihedral, sweep & position; hinge moments, stick forces.

Special Topics:

Dynamic stability: Euler angles; Equations of motion; aerodynamic forces and moments, stability & control derivatives; decoupling of longitudinal and lateral-directional dynamics; longitudinal modes; lateral-directional modes.

Section 3: Aerodynamics

Aerodynamics is the study of the motion of air, particularly its interaction with a solid object, such as an airplane wing. Aerodynamics is a sub-field of fluid dynamics and gas dynamics, and many aspects of aerodynamics theory are common to these fields.

Core Topics:

Core TopicsSub Topics

Section 4: Structures

Structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. 

Core Topics:
