Abstract:
A propulsion device includes a propulsion body and a diversion assembly. The propulsion body includes a propulsion system and a housing accommodating the propulsion system. The housing has an air-intake opening and an air-discharge opening respectively on two opposite sides of the propulsion system. The diversion assembly includes first and second diversion annular sheets. The first diversion annular sheet is disposed outside the air-discharge opening of the housing and having a surrounding center. The first diversion annular sheet is swung relative to the air discharge opening by a first axis passing through the surrounding center. The second diversion annular sheet is disposed outside the air-discharge opening of the housing and concentrically disposed with the first diversion annular sheet. The second diversion annular sheet is swung relative to the air-discharge opening by a second axis passing through the surrounding center, and first axis intersects the second axis.
