Abstract
The invention includes an air mover device used for fire mitigation and protection. The core component is an air mover unit whose discharge airstream can be positioned using air rudders to provide air flows in optimum directions and capacity to counter unwanted fire progression or to promote fires in cases of back-burns. Additional support components include a power supply, its fuel source, a speed control mechanism for the air mover, an air mover inlet protective screen, a sparger unit to impart suppressant or retardant into the airstream, and instrumentation and controls to ensure function and safety of equipment and personnel. This device can be on a static or mobile platform, towed or self-propelled and can be locally or remotely controlled.
Claims22
An air mover device for use in firefighting, comprising:
- an air mover unit to produce a selected volume and velocity of a discharged airstream therefrom;
- a transmission for speed control coupled to said air mover unit for control of the volume and velocity of the discharged airstream;
- an air mover driver connected to the air mover unit to provide power to said air mover unit;
- a first air rudder having a first side and a second opposite side that is placed in contact with said discharged airstream to selectively and controllably direct the discharged airstream in a lateral direction;
- a second air rudder having a first side and a second opposite side that is placed in contact with said discharged airstream to selectively and controllably direct the discharged airstream in a vertical direction;
- a sparger unit communicating with said discharged air stream that injects a suppressant or retardant into the discharged air stream;
- wherein the first and second air rudders act as airfoils to direct the discharged airstream by contact of said respective first and second opposite sides with said discharged airstream;
- and
- wherein the first rudder and the second rudder overlap in a direction of the discharged airstream.
An air mover device for use in firefighting, comprising:
- an air mover unit to produce a selected volume and velocity of a discharged airstream therefrom;
- a speed control element coupled to said air mover unit for control of the volume and velocity of the discharged airstream;
- at least one air rudder having a first side and a second opposite side that is placed in contact with said discharged airstream to selectively and controllably direct the discharged airstream in a desired direction;
- an air mover driver connected to the air mover unit to provide power to said air mover unit;
- a sparger unit communicating with said discharged air stream that injects a suppressant or retardant into the discharged air stream;
- and wherein the at least one air rudder acts as an airfoil to direct the discharged airstream by contact of said first and second opposite sides with said discharged airstream;
- and
- wherein at least one rudder and a second rudder overlap in a direction of the discharge airstream.

- a sparger unit communicating with said discharged air stream that injects a suppressant or retardant into the discharged air stream;
- wherein the first and second air rudders are airfoils to direct the discharged airstream by contact of the discharged airstream on a first side and a second opposite side of each air rudder;
- and wherein the first rudder and the second rudder overlap in a direction of the discharged airstream.
