It consists of a rigid frame which supports, in its central part, a tank of water, a tank of fuel and, in its front part, a control cabin where the craft will be controlled. From the frame or chassis extend lateral arms on which are anchored the rotors which provide lift and motion through the air. In the rear part, there is the system of boost pumps which supply a network of pipes distributed longitudinally in the lower part of the frame and via which the water emerges outside in order to extinguish the fire. The water thus dispensed produces a protective layer so that the apparatus can withstand the temperatures to which it is subjected during action. The craft has wheels for supporting it on the ground which are located under the frame, in the location from where the lateral arms start. <IMAGE>
