TECH GENERAL — CHAPTER 10
Subsonic Aerodynamics
DGCA Syllabus — What to Know
Newton's laws, Bernoulli's theorem, continuity equation, IAS/CAS/EAS/TAS. Aerofoil shape (camber, chord, thickness, nose radius, angle of attack, angle of incidence). 2D and 3D airflow, lift/drag coefficients, CL-α graph, CLmax, CD, profile polar. Tip vortices, induced drag, ground effect. Stall (boundary layer, flow separation, stall speed, wing planform, high-lift devices, stall warning, spin recovery).
