Description / Abstract:
The purpose of this SAE Aerospace Information Report is to disseminate
qualitative information
regarding foreign object damage (FOD) to gas turbine engines used to
power helicopters and to
discuss methods of preventing FOD. Although turbine-powered,
fixed-wing aircraft are also subject
to FOD, the unique ability of the helicopter to hover above, takeoff
from, and land on unprepared
areas creates a special need for a separate treatment of this subject
as applied to rotary-winged
aircraft.
