Abstract: A propeller (100) is disclosed that may include a shell (102) defining an upper opening (102A), a lower opening (102B), an inner surface (102C), and an outer surface (102D). Each of the upper opening (102A) and the lower opening (102B) defines a circular profile along a central axis (AA’). The propeller (100) may further include a plurality of blades (104) attached to the shell (102) on the inner surface (102C) of the shell (102) and extending towards the central axis (AA’), to define a central region along the central axis (AA’). The shell (102) along with the plurality of blades (104) is configured to rotate about the central axis (AA’) to generate an air flow via the central region, from the upper opening (102A) towards the lower opening (102B).
