NOVEL SOFTWARE-DRIVEN VARIABLE-PITCH AND LEVEL FLIGHT CONTROL SYSTEM: PRINCIPLES AND APPLICATIONS FOR SMALL AIRCRAFT WITH A QUADROTOR CASE STUDY
X. Xiong¹, S. Wu¹; ¹International WYNNBEAR Advanced AeroTech Innovation, United States
An exploratory study presents the achievement of variable pitch using simple and reliable fixed pitch propellers. By employing multiple sets of propellers with different blade angles and employing clever layout and control strategies, propulsive efficiency can be increased by up to 35%.
