Abstract: Airborne fire fighting system comprising a helicopter and a pair of tiltable jet engines where the exhaust can be directed at the fire under the control of the pilot or other fire fighting crew. AFFS comprises a rotor-powered craft, fitted internally with a jet engine collinear to the length of the fuselage which has an air intake projecting through the rear of the fuselage. The jet exhaust escapes through a vector able orifice, protruding through the floor of the fuselage of the airborne firefighting platform. The jet exhaust impacts the ground in front of an advancing firewall and bounces through the firewall, extinguishing that segment of the fire. The system can also be used is to disperse snow and ice. The jet engine may also be removed and a smaller jet engine affixed with hydraulic arms to a wheeled mobile to be loaded into the AFFS and delivered to a fire zone where it can used to extinguish fire by remote control.
