Elevator Design Chapter 12 Design of Control Surfaces
Elevator Design Chapter 12. Design of Control Surfaces From: Aircraft Design : A Systems Engineering Approach Mohammad Sadraey 792 pages September 2012, Hardcover Wiley Publications Introduction A very fundamental requirement of a safe flight is longitudinal Control ; which is assumed to be the primary function of an Elevator . An aircraft must be longitudinally controllable, as well as maneuverable within the flight envelope (Figure ). In a conventional aircraft, the longitudinal Control is primarily applied though the deflection of Elevator ( E), and engine throttle setting ( T). Longitudinal Control is governed through pitch rate . (Q) and consequently angular acceleration ( ) about y-axis (or rate of pitch rate). Longitudinal Control of an aircraft is achieved by providing an incremental lift force on horizontal tail.
