Toroidal Propellers May Quietly Pave the Way to UAM Package Deliveries and More

MIT might have a solution for the noise produced by multi-rotor propellers. The Structural and Thermal-Fluids Engineering Group at MIT Lincoln Laboratory is experimenting with toroidal propellers. [PDF] The toroidal propeller consists of two blades looping together so that the tip of one blade curves back into the other.

Key Features:

  • Decreases signals in the frequency range to which humans are most sensitive
  • Reduces noise without requiring supplementary components that add weight and increase power draw
  • Lessens the likelihood that the spinning propeller will cut, catch, or clip objects or surfaces in the drone’s path 
  • Achieves thrust comparable to that of a multirotor drone propeller
  • Allows reliable fabrication with additive manufacturing techniques that make it possible to customize the propeller for various multirotor models and types

Amazon’s drone delivery unit hit with layoffs just as 10-year-old project finally launches

It’s been a decade since Amazon’s Jeff Bezos unveiled the company’s drone project on 60 Minutes. Prime Air now has drone delivery operations in two small markets, but corporate cost-cutting is rampant in the tech industry. Amazon plans to cut 18,000 jobs and Prime Air is not immune. The company won’t say how many layoffs affect the program. Sources said employees in the design, maintenance, systems engineering, flight testing, and flight operations units were part of the layoffs.

Marine Corps buying Valkyrie drones to investigate ‘future autonomous platforms’

The Marines have a $15 million contract with Kratos for two XQ-58A Valkyrie drones. These large aircraft weigh about 6,000 pounds and have a 27-foot-wingspan. Likely missions include strike, intelligence gathering, and electronic warfare. Possible other applications are a “mothership” for small drones and the deployment of munitions.

What is ‘advanced air mobility,’ and why is the Utah Legislature looking to regulate it?

The Utah Legislature has been working on drone regulations and in 2022 a study group was formed to look at updating regulatory laws. A bill is now working through the state legislature that is described as a framework for regulation. Topics being discussed include tracking software for near-ground air traffic, noise concerns, and State supremacy over local jurisdictions

Inside the Department of Energy Project Using Drones to Map Radioactive Waste Storage Vaults

A Flyability Elios 3 drone has successfully completed a 3D LiDAR mapping operation of a storage vault holding radioactive waste. The vault is planned to be removed and the data collected by the drone will aid in planning the project. The operation was conducted last November at the Idaho Nuclear Technology and Engineering Center at the Idaho National Laboratory Site. A team of about 50 people was involved, the top of the vault was covered with a plastic tent (thus creating an “indoor mission), and a crane lifted the vault’s lid and hatch.  Flyability specializes in confined space inspections.

MightyFly’s new autonomous cargo drone carries 100 lb for 600 miles

The MightyFly Cento autonomous VTOL drone is a hybrid with electric propulsion and a hydrocarbon combustion engine that charges the battery in flight. The carbon-fiber airframe weighs 355 lb when fully loaded with a payload of up to 100 pounds. For vertical flight, eight props provide lift while a pusher prop on the back is used for cruise flight.

Drone Strategy 2.0: Creating a large-scale European drone market

The European Commission adopted the European Drone Strategy 2.0 which offers a vision for the further development of the European drone market. The Commission wants to ensure that society supports drones. By 2030, the Drone Strategy envisions a number of services, including emergency services, mapping, imaging, inspection and surveillance; the urgent delivery of small packages, such as biological samples or medicines; Air Mobility services, like air taxis that provide regular transport services for passengers, initially with a pilot on board, but ultimately fully automated operations.

The Commission’s strategy includes operational, technical, and financial actions:

  • Adopting common rules for airworthiness, and new training requirements
  • Funding the creation of an online platform to support local stakeholders and industry implementing sustainable Innovative Air Mobility.
  • Developing a Strategic Drone Technology Roadmap to identify priority areas for research and innovation, to reduce existing strategic dependencies and to avoid new ones arising.
  • Defining criteria for a voluntary cybersecurity-approved drone label.

Senators urge Pentagon to send advanced Gray Eagle drones to Ukraine

After some reports that the Pentagon had decided to not send armed drones to Ukraine, sixteen Senate Republicans and Democrats sent a letter to Defense Secretary Lloyd Austin objecting. In the letter, the Senators say, “This particular [Unmanned Aerial System] will increase Ukraine’s unmanned capabilities in the near term and demands careful reconsideration. Most importantly, armed [Unmanned Aerial Systems] could find and attack Russian warships in the Black Sea, breaking its coercive blockade and alleviate dual pressures on the Ukrainian economy and global food prices.” The General Atomics MQ-1C Gray Eagle drones can hold up to four Hellfire Missiles.

Poachers beware—new drone team launched to assist in wildlife crime investigations

The five Utah Division of Wildlife Resources (DWR) drone law enforcement officers have been trained and have their FAA pilot licenses. The drones will assist officers in their investigations through increased documentation of crime scenes and locating evidence.

uAvionix Awarded FAA contract to Implement and demonstrate C-Band Frequency Assignment Manager (FAM) with Multiple UAS Operations

uAvionix won a contract from the FAA for end-to-end demonstrations of a Frequency Assignment Manager (FAM) as a component of the uAvionix SkyLine™ Command and Control Communications Service Provider (C2CSP) management platform. The system will dynamically assign UAS C-Band Command and Non-Payload Control frequencies to UAS with CNPC radios. uAvionix teamed with the Northern Plains UAS Test Site to develop command and control concepts.

The contract demonstrations include:

  • Managing a pool of frequencies in a geographic area.
  • Allocating available frequencies to a specific CNPC radio for a specific mission.
  • Receiving assigned frequencies for the designated mission.
  • CNPC radios operating on the assigned frequencies.
  • Non-interference when multiple aircraft are operating in the area.

This New Airplane Could Be The First to Fly on Carbon-Free Liquid Hydrogen

Since 2016, the German company H2Fly has been flying an airplane powered by a hydrogen gas fuel cell. The Hy4 is a four-seat aircraft and in April it set a record for the highest zero-emission flight, at 7,230 feet. H2Fly plans to switch from Hydrogen gas to liquid. That would double the range. Testing is scheduled for 2023. The company has entered into a partnership with Deutsche Aircraft to develop a fuel-cell-powered aircraft that will hold up to 40 passengers, with a range of 1,200 miles.

Eye in the sky: SUAS program takes flight at Dover AFB

The 436th Airlift Wing Plans and Programs office at Dover AFB has an sUAS program jointly run with the Bedrock Dover AFB  Innovation Lab. Recently, a Skydio X2D Small Unmanned Aerial System drone was tested during its first operational flight around a static aircraft at Dover on Nov. 4, 2022. The X2D was selected from other Department of Defense-approved systems due to its advanced obstacle avoidance system and other possible capabilities.
