Predicted Flight Characteristics of the Inverted Joined Wing Scaled Demonstrator

Joined wing configuration is considered as a candidate for future aeroplanes. It is an unconventional aeroplane configuration with several possible advantages like induced drag reduction and weight reduction due to the closed wing concept. This paper presents a predicted flight characteristics of its rarely considered version, with front wing above aft wing. Our previous analyses suggest, that joined wing aeroplane L/D grows together with increasing gap and stagger between wings. This paper presents a summary of flight characteristics explored so far.
