Combustion systems with rotary fuel slingers

A combustion system includes a fuel manifold adapted to receive a flow of fuel from a fuel source, the fuel manifold including at least one orifice from which the received fuel is discharged. The combustion system further includes a rotary fuel slinger disposed adjacent to the fuel manifold. The rotary fuel slinger includes a coupler shaft and a slinger disc coupled to the coupler shaft. The slinger disc includes a first portion disposed generally perpendicular to the coupler shaft and a second portion disposed at an angle to the first portion. The fuel manifold is positioned relative to the rotary fuel slinger such that the discharged fuel impinges on the second portion. The rotary fuel slinger is configured to rotate such that the flow of fuel is centrifuged radially outwardly from the second portion onto the first portion and subsequently off the rotary fuel slinger to atomize the received fuel.
