Systems, method, devices and apparatus are provided for reducing drag and increasing the flight efficiency characteristics of aircraft and airships including hybrid aircraft utilizing distributed boundary layer control and propulsion devices. Boundary layer control includes passive systems such as riblet films and boundary layer propulsion devices having a divided and distributed propulsion system disposed in the curved aft sections of aircraft and airships including hybrid aircraft susceptible to boundary layer drag due to degree of curvatures, speed an...
1. A boundary layer propelled airship comprising: (a) a curved airship skin having a fore section and a curved aft section; and(b) a distributed boundary layer propulsion means disposed in said curved aft section having at least one member of said distributed boundary layer propulsion means disposed inside a boundary layer separation area said distributed boundary layer propulsion means selected from the group consisting of: a plurality of micropropellers having a diameter less than the thickness of a boundary layer;a plurality of piezoelectric biomorph ...
