Flight Dynamics –Ii Stability and Control
Flight dynamics –II Stability and control
Prof. E.G. Tulapurkara
Chapter 1 Introduction (Lectures 1,2 and 3)
Keywords : Importance of stability and control analysis ; brief historical background ; basic concepts – static stability, dynamic stability, longitudinal, lateral and directional stability, control fixed and control free stability ; controllability; subdivisions of the subject; course outline. Topics 1.1 Opening remarks 1.2 Brief outline of historical developments 1.2.1 Early developments 1.2.2 Subsequent developments 1.3 Basic concepts about airplane stability and control 1.3.1 Stable, Unstable and neutrally stable states of equilibrium 1.3.2 Types of motions following of disturbance – subsidence, divergence, neutral stability, damped oscillations, divergent oscillation and undamped oscillation. 1.3.3 Static stability and dynamic stability 1.3.4 Recapitulation of some terms – body axes system, earth fixed axes systems, attitude, angle of attack and angle of sideslip 1.3.5 Longitudinal and lateral stability 1.3.6 Control fixed and control free stability 1.3.7 Subdivisions of stability analysis 1.4 Controllability 1.5 General remarks 1.5.1 Examples of stability in day-to-day life 1.5.2 Airplane stability depends on flight condition 1.5.3 Stability and controllability are not the same 1.5.4 Stability is desirable but not necessary for piloted airplanes 1.5.5 Small disturbance analysis of stability
