Title:
APPARATUS AND METHOD FOR FLUID MANIPULATION
Document Type and Number:
Japanese Patent JP2022020753
Kind Code:
A
Abstract:
To provide a fluid manipulation apparatus, such as a main rotor system of a helicopter, which can be configured to reduce electric power consumed during hovering and increase hovering endurance.SOLUTION: An intentional fluid manipulation apparatus assembly includes a first thrust apparatus that imparts a first induced velocity to a local free stream flow during a nominal operation requirement. The first thrust apparatus creates a streamtube. A second thrust apparatus is located in a downstream portion of the streamtube. The second thrust apparatus imparts a second induced velocity to the local free stream flow. The second induced velocity at the location of the second thrust apparatus has a component in a direction opposite to the direction of the first induced velocity at the location of the second thrust apparatus.SELECTED DRAWING: Figure 3
