UNIQUE BAROMETRIC PRESSURE CONTROL:
Drones, especially waterproof flying drones have a unique challenge in the sense that they use barometric pressure to control their altitude/hight. To this end, they must breathe and displace roughly as much as 20% of their internal air volume during each flight. As the electronic components and battery heat up the internal air expands in volume and the excess volume needs to be pushed out of the drone’s sealed shell.
All other existing “waterproof” drones make use of a breathable cloth/paper-like membrane through which the air is expelled. This membrane method is used as there is no current mechanical means (valve) that allows bidirectional free airflow but seals water flow off and reopens as soon as there is no water present.
Once the drone starts to cool down, say when it starts to rain or when it lands in the water, or even just at the end of each flight, the air cools down and contracts and at this point new air is drawn into the drone by the vacuum formed from the contracting air and components, the same happens each time the drone descends, the external barometric pressure goes up and air is forced in. If the membrane is wet at this stage it becomes a barrier to free air movement but
despite this barrier, the vacuum will still draw water and or water vapor into the drone and electronics compartment causing long term damage. This wet membrane is a significant barrier to free airflow that retards the heating/expanding air from escaping the drone freely causing the internal pressure to rise which in return gives false readings to the flight controller resulting in the drone’s unintended and undesirable gain in altitude.
To address this unique challenge each Gannet is fitted with a flexible internal flight bladder. The concept is incredibly simple, and very similar in nature to a fishes swim bladder, a short a tube is connected to a strategically placed and shielded opening to the exterior of the drone, this tube is then connected to the flight bladder, which at rest has approximately 20% of the drones internal volume in it. As the drone heats up the air expands, this pushes on the outside of the bladder and forces the air in the bladder out through the opening decreasing the bladder size.
Any air that is drawn back in when the drone cools down or changes altitude
simply fills the bladder through the tube and can never reach the electronics. It does not matter what moisture content is in the ”air” as all that matters to the drone is displaced volume, which function the flight bladder fulfills effortlessly. Should water be drawn in at this stage it would simply run out at a later stage and be replaced with air once out of the water. This unique and patent-pending design ensures that the electronics will never see the external environment, be it humid air, rain, snow, salt spray or ocean water. The electronics stay dry at all times and with perfectly balanced barometric pressure this ensures stable flight without
uncontrollable altitude gain as is the case with all other “waterproof” drones.
