Abstract
An airflow generator including a ducted fan and a plurality of air multipliers for discharging air along a first axis, each air multiplier including an inlet and an outlet, said ducted fan being fluidly connected to the inlets (8) of the air multipliers, wherein the air multipliers are differently sized to provide airflows of different cross-sectional size, and are positioned such that smaller ones of the air multipliers provide airflows reinforcing a respective sub-portion of the airflows provided by larger air multipliers, and wherein the air multipliers are distributed along the first axis.

An airflow generator comprising:
- an electrically powered ducted fan provided with an inlet and an outlet,
- a fluid conduit;
- and
- a plurality of air multipliers for discharging air along a first axis, each air multiplier comprising an inlet and an outlet,
- said fluid conduit fluidly connecting the outlet of the ducted fan to the inlets of the air multipliers,
- wherein the air multipliers are differently sized to provide airflows of different cross-sectional size, and are positioned such that smaller ones of the air multipliers provide airflows reinforcing a respective sub-portion of the airflows provided by larger air multipliers, and
- wherein the air multipliers are distributed along the first axis.
