Damage Incurred on a Tilt-Wing Multipropeller VTOL/STOL Aircraft Operating Over a Level, Gravel-Covered Surface

摘要

Damage was incurred by a tilt-wing type VTOL aircraft which was inadvertently operated from a level macadam runway covered with loose and embedded gravel. The basic flow phenomenon appears to be of the same type previously reported in NACA TN 4124 in connection with static-thrust force measurements made using a multipropeller VTOL aircraft model.
