XP-108 "CHAK-CHAN" Ducted Fan VTOL aircraft. Original configuration features 4 rows with 7 (each) pivoting Electric Ducted Fans (EDF’s), providing efficient forward flight, VTOL and everything in-between. In forward flight, EDFs are aligned ‘in series’ to provide linear forward thrust, and turn long horizontal surface into and ‘augmented ‘ lifting wing area. In a hover EDF’s work ‘in parallel’ to provide maximum lift. During transition, EDF’s adjust exact position for optimal lift, thrust and control vector.
