VRAD – Vortex Ring Accelerator DeterrentFlock Free
This unique VRAD produces high-speed vortex rings that travel thousands of feet and can impact its target not just acoustically but physically. Due to the nonlethal nature of this technology, it is rapidly gaining acceptance and interest in the pest and bird deterrent industries. The VRAD may be the only non-lethal technology that can move birds-in-flight and this ability is of key interest to anyone involved in Bird Strike and BASH programs, Agriculture, Waste Management and Oil Sands Bird Management programs.
The VRAD uses combustion to propel exhaust through a vortex ring generator creating a high-velocity vortex ring which then passes through an accelerator causing the 3-foot diameter vortex ring of air to reach speeds up to 200 mph. In addition to a fierce concussion (many times the volume of typical air canons common to current bird management programs), this ring of air screams as it flies causing various levels of distress in bird and wildlife populations as well as causing direct hits in many instances. A direct hit has never been seen to cause any damage to the target but the irritation level is vastly beyond any other product available.
Recent test firing at DFW detected air disturbances and concussions of measurable volumes at 5-6 miles.
Testing to Date
The VRAD has been tested for the past year in a variety of locations. The majority has been on bird problems in crops environments like cherries, pistachios, and blueberries. These are great testing areas as the birds are drawn to these as food sources and become very difficult to move once they become acclimated to feeding on these crops.
Initial testing has proven not only to drive birds away at great distances but to keep them away for long periods of time. Here is a quote from Keenan Farms where we recently tested the VRAD for distance on pistachio dump sites.
“The team at Keenan Farms was able to demo the VRAD last week at our facility. We have used standard bird cannons and also used personnel with shotguns to try and deter birds away from our orchards and other open fields to no avail. We launched the VRAD at several flocks of crows from ¾ of a mile away. The birds immediately left the area and did not return to the original field. Several hours later they were located in a different location and after firing a couple of times they were pushed out again. They never returned that day. From the test, we ran on a single day I was very impressed with the VRAD and its capabilities. There is nothing like it in the market today. Feel free to call me personally with any questions on our trial.
Sincerely, Steve Skaggs Plant Engineer - Keenan Farms
Every shot with the VRAD drives birds away. Of course, testing has not been done on every bird species nor in every environment which is one of the reasons for this proposal.
We have been successful thus far in moving birds not only from crops but also in-flight. To our knowledge moving birds-in-flight is something that is not currently possible. The VRAD has been able to move birds of prey and huge flocks of airborne crows. One of the uniquenesses of the VRAD is the ability to use it just like artillery. As such The VRAD can take an initial shot at a bird or flock of birds to get them moving then follow them in-flight with successive shots.
This ability seems to horrify the birds, especially if the first shot is at a close range. Successive shots keep the birds off-guard and moving and they will not dare land while the VRAD is in operation.
A Research and Development Contract was recently signed with the Montana Resources Copper Mine in Butte, MT where the toxicity of their lake accidentally killed thousands of Snow Geese making the news worldwide. This contract in addition to helping MR prevent another accidental bird kill is designed to help us understand why the VRAD seems to be so effective. They have committed a Wildlife Biologist to the test program to help us understand not only “why” the VRAD is so effective but also whether there is any potential damage to birds or wildlife.
The VRAD can be mobile mounted to a truck, trailer or boats. They can also be permanently mounted and automated to rotate and tilt. They can even be connected to radar systems and cameras and become fully automated and fired remotely. The VRAD was also designed to be used in inclement weather conditions, even at sea.
