US 2026/0199719 A1 · Air Mover Device And Method For Firefighting

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 and/or a directional control assembly 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, balancing feet, a removable nozzle, 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.

Dependent claims

An air mover device for use in firefighting, comprising:

an air mover unit to produce a selected volume and velocity of a discharged airstream from the air mover unit;
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 contactwith said discharged airstream to selectively and controllably direct the discharged airstream in a vertical direction;
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.

A method of fighting a fire using an air mover device, comprising:

providing an air mover device comprising:
(a) an air mover unit to produce a selected volume and velocity of a discharged airstream from the air mover unit;
(b) a speed control element coupled to said air mover unit for control of the volume and velocity of the discharged airstream;
(c) a first air rudder communicating with said discharged airstream to selectively and controllably direct the discharged airstream in a first direction;
(d) a second air rudder communicating with said discharged airstream to selectively and controllably direct the discharged airstream in a second direction;
position the air mover device at a desired location in proximity to a fire requiring control;
energize the air mover unit to produce the selected volume and velocity of a discharged airstream;
selectively operate the first and second rudders to directionally control a discharged airstream;
wherein the first and second air rudders act as airfoils to direct the discharged airstream by contacting first and second opposite sides of both said first and second air rudders with said discharged airstream;
and
wherein the first and second air rudders overlap in a direction of the discharge airstream.
