Development of a Novel Tailless X-Type Flapping-Wing Micro Air Vehicle with Independent Electric Drive

Biomimetics
A novel tailless X-type flapping-wing micro air vehicle with two pairs of independent drive wings is designed and fabricated in this paper. Due to the complexity and unsteady of the flapping wing mechanism, the geometric and kinematic parameters of ...

Some approximations to the flapping stability of helicopter rotors [PDF]

The flapping equation for a helicopter in forward flight are reported which have coefficients that are periodic in time, and this effect complicates the calculation of stability.
