Fire resistant aerial vehicle for suppressing widespread fires

Abstract

A concentric, double hull, damage tolerant airframe vehicle double clad with a lightweight, impact resistant ceramic matrix composite for heat shielding and flame resistance, and fitted with insulation, to provide thermal protection from 35° C. to 1,650° C. of the internal fuselage areas for an extended period of time within an extreme heat environment, that will serve as a semi or fully autonomous vehicle, manned or unmanned, preferably an unmanned aerial vehicle designed as the delivery means to suppress or extinguish flames by repeatedly discharging pressure waves against flames without having to exit the fire environment.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Application No. 60 / 598,602 filed on Dec. 14, 2017, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to fire-extinguishing vehicles, and in particular, aerial vehicles for extinguishing fires over a widespread area.2. Description of Related Art[0003]Several prior art devices teach the use of a “smart” system for delivering, targeting and the release of fire retardant material. A common feature is the use of GPS, paired with a parachute, sled or glide system, whereupon achieving a pre-determined location or height above the tree line level of a fire, an explosive charge is then employed to discharge its chemical load accordingly. Several are ground impact devices that employ an explosive charge to spread its contents or serves as a failsafe mechanism should the device not ...

AI Technical Summary

Benefits of technology

The system effectively extinguishes fires by disrupting the flame's energy source, allowing continuous operation within the fire environment, and can recharge and discharge the shockwave mechanism efficiently, providing a tactical advantage in suppressing large-scale fires.

Problems solved by technology

These devices, while utilizing inertia as a delivery mechanism when projected or airborne dropped to a fire environment unfortunately do not employ today's smart technology to think and learn nor have the capacity to effect true flight within the tree line of a fire.

One of the limitations here is that it is not a precise delivery mechanism that can maneuver on its own accord to deliver a fire-retardant package.

The air brake is applicable to steady the device but is not part of a true “flight” system nor deployable to help offset the blast created at the time of detonation.

While its retractable wings are deployable at the time of launch, there is no indication that such can be retracted for flight below tree top levels, and it has limited “lift” ability.

Effectiveness may be limited to how far above and lateral to impact the fire retardant can spread and may not be as effective as an airburst vertical fire suppression element

However, it does not disclose how the acoustic technology can be adapted for a wildfire.

However, CN205891227U does not teach how the UAV can perform fire suppression within a fully evolved fire

In sum, the prior art does not teach an ordinary skilled artisan to produce a system or method for discharging pressure waves inside a widespread fire to suppress or extinguish fires.
