Abstract
Official abstract text for this publication.
Methods, apparatus, systems and articles of manufacture are disclosed for a first link to rotate about a pin joint, a second link rotatably coupled to the first link, the second link having a nozzle at a first end and a weight at a second end opposite the first end, and a fluid inlet including a funnel portion and an opening, the funnel portion having a conical taper converging towards the opening.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: a first link to rotate about a pin joint; a second link rotatably coupled to the first link, the second link having a nozzle at a first end and a weight at a second end opposite the first end; and a fluid inlet including a funnel portion and an opening, the funnel portion having a conical taper converging towards the opening, the nozzle and the opening including poppet valve components to fluidly couple the nozzle to the opening. 2. The system of claim 1 , wherein the conical taper of the funnel portion is to urge the nozzle towards the opening to accommodate misalignment between the nozzle and the opening. 3. The system of claim 1 , further including a pump to pump fluid to the nozzle from a fluid reservoir. 4. A system comprising: a first link to rotate about a pin joint; a second link rotatably coupled to the first link, the second link having a nozzle at a first end and a weight at a second end opposite the first end; a fluid inlet including a funnel portion and an opening, the funnel portion having a conical taper converging towards the opening, the funnel portion to interface with the nozzle; a structure; a stationary member; a first arm rotatably coupled to the structure and the stationary member; and a second arm rotatably coupled to the structure and the stationary member. 5. The system of claim 4 , further including a linear actuator rotatably coupled to the first arm at a first distance from the structure, the linear actuator rotatably coupled to the second arm at a second distance from the structure, the second distance greater than the first distance. 6. A system comprising: a first link to rotate about a first pin joint; a second link rotatably coupled to the first link at a second pin joint, the second link having a nozzle at a first end and a weight at a second end opposite the first end, the nozzle having a vertical lever arm relative to the second pin joint; and a fluid inlet including a funnel portion and an opening, the funnel portion having a conical taper converging towards the opening, the funnel portion to interface with the nozzle. 7. A system comprising: a first link to rotate about a pin joint; a second link rotatably coupled to the first link, the second link having a nozzle at a first end and a weight at a second end opposite the first end; and a fluid inlet including a funnel portion and an opening, the funnel portion having a conical taper converging towards the opening, the funnel portion to interface with the nozzle, the opening fluidly coupled to a fluid storage tank of a rotorcraft. 8. The system of claim 7 , wherein the rotorcraft is an Unmanned Aerial Vehicle (UAV).
