Automatic synchronizing for aircraft alternators

THE PIONEERING of 3-phase 400-cycle constant frequency electric systems for modern aircraft has presented many difficult problems but has given a basic solution to the problem of meeting unprecedented electric load requirements. Load requirements have increased because of the increasing need for complex electric control systems and electronic devices in the maintenance of air supremacy. As a consequence of this greater dependence on electric power, greater reliability and simplicity of operation of the power systems are now demanded.
