  • Patent number: 11255321
    Abstract: A UAV propulsion system is disclosed that utilizes a crankcase having a first crankcase compartment and a second crankcase compartment. Each crankcase compartment includes a corresponding cylinder assembly and piston, with each piston being interconnected with a rotatable crankshaft. A first airflow path extends from an exterior of the UAV propulsion system to the first crankcase compartment, and a separate second airflow path extends from the exterior of the UAV propulsion system to the second crankcase compartment. A first rotary valve may be mounted on and rotate with the crankshaft to control the airflow along the first airflow path to the first crankcase compartment, while a second rotary valve may be mounted on and rotate with the crankshaft to control the airflow along the second airflow path to the second crankcase compartment.

  • Patent number: 8079551
    Abstract: An enhanced aerial delivery system addresses issues raised when large quantities of fluids, powders, and other agent materials are to be transported in and aerially dispersed by aircraft. Some aspects include positioning and securing of tanks aboard the aircraft to facilitate management and safety of the tanks and aircraft. Other aspects address coupling of the tanks and associated piping to lessen structural effects upon the aircraft. Further aspects deal with channeling, containing, and dumping stray agent materials that have escaped from the agent tanks on board the aircraft.

  • Patent number: 6170768
    Abstract: A dilute phase pneumatic materials conveyance apparatus is disclosed having a pneumatic accelerator which is capable of conveying materials through a gas stream which is selectively patterned. The conveyance apparatus also includes a source-gas manifold and control apparatus which enable selective control of the apparatus on a real time basis to achieve desired gas pattern flows through the apparatus to achieve selected particle dispersion, isolation, stratification, electrification, classification and entrainment of material and to convey it through a processing conduit. The configuration of the conveyance apparatus also enables further processing, including drying, sorting, pulverization and classification of the materials. The conveyance apparatus also enables classification of materials based on the aerodynamic diameter of the particles being conveyed because of the ability to achieve particle isolation.
