A LAMINAR FLOW, PROPULSIVE, JET-FLAPPED CONCEPT FOR ELECTRICALLY POWERED TRANSPORT AIRCRAFT

Friction drag constitutes approximately half of the total subsonic civil transport aircraft at cruise conditions. Several means were examined to control flow over an and achieve laminar flow. Here, a new concept for friction reduction in form integration aerodynamics propulsion is put forward. Engines buried wing rear fuselage suck boundary layer entire surface, then, they used it as intake air exhaust through ducts. At wings, engines jet flap trailing edge providing distributed propulsion. By this flow, propulsive established aircraft, resulting substantial reduction. The analysis showed that out four electrically powered versions considered only combined lift distribution with tailless about be feasible. It was also found example design inappropriate. expected purposely based on proposed would bring within specific energy levels present batteries.
