Post# of 11107
uses a vertical squirrel cage with two strong high rpm fast turning motors pulls air up into the center of the drone & discharges at 4 or 6 outboard ports with controlled jet port air exhaust valves for lift. Excess dump valve is discharged through the top center and adjustable depending on load factors. It has to discharge through a umbrella type duck and damper as to not effect lift or movement. Or controlled by motor speed and counter motor speed with much less excess exhaust air to deal with.
The Blade-less puffer jet drone.... The valves can be just as controlled as 4 or 6 independent motors. The discharge valves also pivot for better movement and control and for A Balance between the excess or dump valve. and discharge lift valves.
THE JETSON DRONE You know that puffer sound as they drive.
