Pusher-Prop Quad Will Save the Ceilings

In the early days of aviation, planes used pusher propellers. A pusher prop is typically behind the wing, and the concept probably came from boating, with the ship’s screws located on the stern to push the vessel through water. It took a few years for aerospace engineers to realize that puller props (mounted on the nose of the airplane) were superior because they spun through clean, not dirty air. The air behind the wing is […]

DJI’s Answer to EM Interference: No Touching

Straight from the depths of ‘duh’, comes this peculiar patent application for separation of electromagnetic interference-causing flight controllers and sensitive sensors that would be useless if in proximity of EM interference. DJI proposes to distance the guts of the controller from the sensor between 3 cm and up to 50 cm away, even if that means putting the sensor on a mast (or an “extension member”). According to the application, “operation of navigational, surveillance or […]

From the reading of the patent application, the camera is only a part of what this thing can do. As the patent says, “existing unmanned aerial vehicle designs can be less than ideal for providing unobstructed viewing […]
