Engineering Mathematics is a critical section in the GATE AE exam. The core topics include Linear Algebra, Calculus, and Differential Equations. Linear Algebra covers vector algebra, matrix algebra, systems of linear equations, rank of a matrix, eigenvalues, and eigenvectors. Calculus involves functions of a single variable, limits, continuity and differentiability, partial derivatives, and various integration techniques. Differential Equations focus on first-order linear and nonlinear differential equations, higher-order linear ODEs with constant coefficients, and partial differential equations.

Special Topics

The special topics in this section include Fourier Series, Laplace Transforms, Numerical methods for solving linear and nonlinear algebraic equations, Numerical integration and differentiation, Complex analysis, Probability, and statistics.

Section 2: Flight Mechanics

Core Topics

Flight Mechanics covers the basics of atmosphere properties, classification of aircraft, airplane configuration, and primary flight instruments. Key topics include airplane performance, static stability, and the understanding of aerodynamic forces and moments. This section also covers the dynamics of different flight conditions, such as take-off, landing, climb, descent, and turning flight.

Special Topics

Special topics include dynamic stability, Euler angles, equations of motion, and the decoupling of longitudinal and lateral-directional dynamics.

Section 3: Space Dynamics

Core Topics

Space Dynamics in the GATE AE syllabus covers central force motion, trajectory determination, orbital period calculations, Kepler’s laws, and escape velocity. These topics are essential for understanding the dynamics of spacecraft and satellite motion.

Section 4: Aerodynamics

Core Topics

Aerodynamics is one of the most crucial sections in aerospace engineering. The core topics include Basic Fluid Mechanics, Potential Flow Theory, Airfoils and Wings, and Compressible Flows. This section covers the fundamental principles that govern the flow of air over surfaces and the resulting aerodynamic forces.

Special Topics

Special topics in Aerodynamics include Wind Tunnel Testing, Measurement and visualization techniques, and Shock-boundary layer interaction.

Section 5: Structures

Core Topics

The Structures section focuses on the strength of materials, flight vehicle structures, and structural dynamics. Core topics include stress and strain analysis, failure theories, torsion, bending, shear of thin-walled sections, and vibration analysis of structural components.

Special Topics

Special topics include vibration of beams, theory of elasticity, and the application of equilibrium and compatibility equations in structural analysis.

Section 6: Propulsion

Core Topics

Propulsion is a vital section that deals with the principles of thermodynamics, aerothermodynamics of aircraft engines, and the performance of various types of propulsion systems such as turbojets, turbofans, and rockets. Key topics include thrust calculations, efficiency analysis, and the dynamics of turbomachinery.

Special Topics

Special topics include the aerothermodynamics of non-rotating propulsion components, turbine blade cooling, and compressor-turbine matching, along with an understanding of surge and stall phenomena.
