X49A Sequence Oct 07
Uploaded by: munacra
Video Stream Description:
A modification of the BLACKHAWK helicopter.
I can only assume that the wings on this aircraft will help compensate for retreating blade stall. As the forward airspeed increases more lift is generated by the wings, and the stalling of the retreating blade becomes more and more insignificant.
