Improved VTOL Coaxial Blades

The Osprey is a problematic animal. Not the bird, the aircraft. It took many years and 36 lives (to date) to design a tilt-propeller ship that can take off like a helicopter and fly like an airplane. What if there is a better design? King Abdullah of Jordan thinks so. A recently-granted US Patent discloses a VTOL vehicle that can take off like a helicopter and presumably fly like a plane. The design, using coaxial counter-rotating […]

Intelligent Drone Communication, by Raytheon

Raytheon is no slouch when it comes to technology, and this is no exception: communicating with a drone for military applications is of prime importance. After all, that’s why you launched the UAV in the first place. The need for improved communication are ever-present: “Satellite transponders for military and/or commercial use are oversubscribed and expensive to put in place and maintain. Current RF transponders lack intelligence. Users of low power transmitters must therefore communicate with non-intelligent transponders […]

Drones Navigate RFID Highway

As more and more UAVs clutter the sky, navigation becomes a real issue. Delivery by drone sparks some of these questions: how do you prevent collisions? Optimize efficiency? Keep track of inventory? Certainly, GPS-borne navigation is the flavor du jour, but it’s not the only nav protocol. Along comes Azure Sky Group LLC, and their patent application for radio frequency identification (RFID) method. RFID is nothing new, and most new credit cards have a chip that works on RFID. […]

Boeing Counters Contingencies for Smaller Drones

So you’re operating a UAV, and the engine quits. Is it certain death for your drone? Boeing says ‘no’. According to their patent application, “Larger UAVs and manned aircraft often have redundant systems for communication (e.g., SATCOM) and navigation (e.g., inertial navigation) that enable them to respond to jamming and other contingencies without losing communication and navigation. That is, they have many spectral degrees of freedom. On the other hand, small UAVs typically cannot tolerate the weight, […]

UAS-In-A-Box Adapts to Various Missions

When you leave your base for the field and plan to use a long-range drone, you pack a long-range drone. It will have characteristics of a UAV designed for long, continuous flight and will be able to stay up for a while. However, it will have the maneuverability of a bucket of gravel. What if your mission parameters change in mid-stream, and you need a drone with way more pep, agility, and a smaller girth? […]

Micro-Drone Rolls, Flies, Gathers Intel

Although this looks like a toy called the “Sky Walker”, this drone is far from it. The Applicant, l’INSTITUT SUPERIEUR DE L’AERONAUTIQUE ET DE L’ESPACE, funded by the French Ministry of Defense, has invented a little drone to gather recon inside buildings. It was built as a “multi-mission microscale aerial vehicle. It comprises elements allowing a microscale aerial vehicle to move or roll across a surface, in particular on the ground, and making it capable […]

When Pigs Fly – NOWs Replace SOWs and COWs

Notwithstanding our technological prowess, Mother Nature has a sinister sense of humor, and stuff happens beyond our control. When disaster strikes, it is crucial to establish a communication grid as quickly and efficiently as possible. Bandwidth-hungry networks help coordinate search and rescue, law enforcement and recovery personnel. Sure, there exist “cellular on wheels” (COWs) and “system on wheels” (SOWs), which are carted on trucks into hotspots, but what if there are no roads, or personnel […]

Boeing Introduces Remote Charging Stations

Suppose you are tasked with inspection and maintenance of a pipeline. Sure, you can send out a team of engineers with camping gear to march up and down the pipeline, looking for rust and leaks. Or, you could have one drone flying back and forth doing the same job. The latter sounds like an impossible task, given that a drone’s battery lasts between 15 and 20 minutes. “Not on my watch”, said Boeing’s Spanish branch. […]

First Successful FAA Drone Delivery? There’s a Google Patent for That

Today will go down in history: a new distribution channel has arrived. While it is not as glorious as the Inter-Webs, getting deliveries by drone is kind of a big deal. What took 90 minutes of arduous driving now takes 20 by a little flying machine. Emergency supplies, fresh medicine, and not to forget, warm pizza and cold beer, are all within a closer, more palpable and environmentally-friendly reach. Australian drone manufacturer Flirtey was the […]

Robust Communication Protocol Improves Drone Experience

So you have your expensive drone in the sky and want streaming video to your pilot, the camera operator, the client’s tablet and the client’s girlfriend’s laptop. That’s a lot of signal for the drone to transmit, not to mention the signal it expects to receive from the pilot. Not all signals are the same. Thus, DJI has applied for a patent for “cyclically repeating time division multiplexing”, an oscillation of “I’m listening” and “Here […]
