NASA Puffin Aircraft Concept

puffin-20100121-600

In terms of aircraft concepts, there’s always something new happening all the time. The NASA Puffin concept is an electric personal helicopter airplane similar to the Osprey. The Puffin can take off and land vertically, then switch to horizontal flight once airborne. The design is simple and almost elegant but not quite. The engine (motor) fairings and cones look a little too much like hollow tubes while the tail fins could use a little sweep to them – at least on the leading edge. I suppose the open canopy would also take some getting used to given the proxity of the propeller blades and any potential impact.
