Abstract
An instructive algorithm for aircraft elevator sizing to be used in preliminary aircraft design software
Highlights
The longitudinal control is the essential elevator function
It is imperative for the designers to assess the control authority of candidate configurations early in the preliminary design phase
Elevator sizing is one of the controllability concepts that should be involved in the preliminary design process
Summary
The longitudinal control is the essential elevator function. For a safe flight, the aircraft should be longitudinally controllable plus maneuverable. The longitudinal control can be accomplished by affording an additional lift force on the horizontal tail [01] It is basically directed through elevator deflection and engine throttle setting. Note that the longitudinal control of the conventional aircraft is not joined with the lateral-directional control, and the elevator sizing process is unrelated to rudder sizing process [02]. Nicolosi released his software (ADAS) [08] in 2011 All these software packages present the elevator sizing indirectly by offering just the stability and controllability derivatives, dimensional and non-dimensional. All these researches are proposed for the aircraft industry and are not planned for instructional use., which consecutively, are out of the scope of the paper
