A Bat-Wing Aircraft Using the Smart Joint Mechanism

Abstract:

Article Preview

A bat-like aircraft is proposed, using a smart joint mechanism to actuate the morphing of the wings. The smart joint stays in its deformed shape after cooling, which can be up to 5% of 25 mm length joint. The morphing of the wing shapes of three different bat species is evaluated using a planar lifting line analysis. The morphing improves the lift coefficient over 1000% and the lift to drag ratio over 300% at an angle of attack of 0.6°. The results compare well with what is expected from the type of flight and morphology that has been documented for the bats.
