    摘要: An unmanned aerial vehicle having a fuselage, a water collection and emission equipment, wings, linear reinforcements, a landing gear and a vertical fin. The water collection and emission equipment has buoyancy units, a sealed cabin, a water pump and a water collection and emission pipe. The sealed cabin is detachably connected to the fuselage, and a compartment is arranged in the sealed cabin. The water pump is arranged in the compartment and the side wall of the sealed cabin has at least one concave part which is concave towards the direction of the inner cavity used for slowing down the swaying of water.

    摘要: A dump gate system for a fluid hopper in a firefighting aircraft. A gate sealably engages a gate opening in the hopper at a closed position. The gate is hingedly connected about the gate opening, and a drive shaft is supported within the hopper. A crank arm is fixed to the drive shaft and is further coupled to the gate by a connecting link. The crank arm and the connecting link define an over-center geometry while the gate is at the closed position, such that weight of the fluid on the gate induces torque on the drive shaft in a gate-closing direction. A linear electric motor is selectively coupled to rotate the drive shaft in a gate-opening direction to thereby enable control of the fluid flow from the hopper according to an angular position of the drive shaft.
