The firefighting helicopter fans comprise a left pivoting cowled fan and a right pivoting cowled fan mounted onto the sides of a helicopter. The fans may be used to create an airstream, which counters the prevailing wind and/or blows flames and embers away from unburned materials. The fans are each protected by a cowl that surrounds the blades to protect the blades and direct the airstream. The left pivoting cowled fan and the right pivoting cowled fan are each coupled to the helicopter by a pivot axis and a pivot motor which allows the fanes to be aim directly forward, directly down, or any angle in between.
