Active flow control by the use of DBD actuators has been proven to be a promising concept for the delay and even elimination of boundary layer separation. In order to further develop these actuators, the interaction between the plasma and the flow under different operating conditions has to be investigated.
The cruiser-feeder concept includes a cruise-optimized aircraft that stays aloft for extended periods while feeder aircraft transport passengers to the cruiser. The endurance of a cruiser aircraft that uses nuclear power to transport up to 1000 passengers is only limited by maintenance intervals.
Solar Impulse 2 set a new world record for the furthest flight for an aircraft, simply powered by the sun.
