"Closest we have seen is the gas gun and splatter gun label additions for some herbicides. This has set the precedent for low volume application but we still have a larger battle with getting this approved for aerial application. The companies may…"
"What we have been doing is invasive woody weed control so not for deforestation. Many woody weeds such as Blackberry Lantana and Prickly Acacia have the ability to strangle local habitat to the environments detriment.
"Thanks George You are correct I often tie myself in knots a bit when I try to simplify the complex. Vortices are related to the lift produced by the aerofoil so will often have a higher impact at slow speed or in a high lift flaps down…"
"Ok big question so will start with the simple answer in that most sprayers are set up to suit the characteristic of the air frame on which they are fitted.This means sprayers will be calibrated to to at the correct volumes at the safe operating…"
"I can forward you a copy of a local research document if you pm me an email address.
Do pay attention to what George is saying as you are entering one of the most legislated areas of aviation and as a current licensed applicator I can confirm…"
"It comes down to the particle size ans consistency of the droplets that you want to apply. This also has a direct effect on drift and the thus the control of where your chemical ends up. Current thinking is towards larger droplets for better control…"
"I can see some big challenges to come with this.
My best theroy so far for something so far would be to go a single ducted main fan (with CR props to eliminate torque) that runs to 4 separate ducts to vector thrust. a servo controlled waste…"
"Maybe just maybe this could be an argument to register all air frames with certain capabilities. If the air frames were registered the current autopilot capabilities and parameters could then be taken into account and thus enable or deny the export…"
"Fair point. I worked indirectly with Elbit skylark Uavs that used an air cushion to minimise damage on stall recovery.
My assumption was that a small soda type gas cartridge feeding a ballon or airbag would arrest and control descent…"
"My view is that we will start with the smaller innovators with small machines who will prove the concepts. As the concept becomes proven the economies of scale will click in and the proven designs may be upscaled with the expertise of larger…"
"Farmers will also support there own ahead of any outsider so any local kid who has a go will get jobs well ahead of a townie or interstate vulture. I envisage a few farmers sons will start local contract businesses much the same as for contract…"
"Good analysis Ultimately the larger companies will probably only contribute in adding air frames and production capacity for existing designs and concepts unless they can interact better with end users.
I believe the production of Ag planes took a…"
