424 Personal eVTOL

Another personal eVTOL, cops flying BVLOS, military drones with facial recognition, a lethal drone designed in Australia, the Lilium Jet eVTOL, and moving air quietly.

Is this one-seat flying saucer the future of flight?

ZEVA Aero designs and builds electric Vertical Takeoff and Landing (eVTOL) vehicles. The company’s flagship product is the Argon, based on a pre-existing airframe. But their Zero is a personal eVTOL for one person. It launches with the pilot standing, but the position is prone in horizontal flight. The 8-foot-wide flying saucer-shaped aircraft uses 8 propellers and is expected to cost $250,000.

A one-eighth-scale model has been flight-tested and tethered tests are underway with a full-sized prototype. Zeva says the prototype should be ready for remote-controlled flights within a month, and tests with a pilot could take place in three to six months.

Welcome to Chula Vista, where police drones respond to 911 calls

The Chula Vista, California police department operates 29 drones. The program runs 10 hours a day, seven days a week using four launch sites. Officers routinely request aerial reconnaissance. More than 1,500 U.S. police departments use drones, mostly for search and rescue, to document crime scenes, and to chase suspects. About 225 police departments have FAA waivers to fly BVLOS. Privacy and civil liberty groups are taking notice.

US Military Signs Contract to Put Facial Recognition on Drones

The Air Force’s Drones Can Now Recognize Faces. Uh-Oh.

The U.S. Air Force plans to deploy facial recognition technology on drones. RealNetworks LLC has the contract to supply its SAFR technology on small drones used for special operations missions. RealNetworks says SAFR Scan is “the first full-featured intelligent biometric access controlled edge solution.”

Australian-designed lethal drone to be unveiled at Avalon Airshow

BAE STRIX

BAE Systems Australia unveiled the armed STRIX VTOL at Avalon 2023. It’s a hybrid, tandem wing, multi-domain and multi-role UAS that could be used for air-to-ground strike, persistent ISR, and as a loyal wingman for military helicopters. It can carry up to a 160kg payload over 800km with a variety of munitions. The collapsed footprint is only 2.6m x 4.5m (roughly 8.5 x 15 feet).

Lilium sees premium service entry for Lilium Jet eVTOL

Vertical flight takes a lot of energy and most eVTOL designs have significant aerodynamic drag. These limit, l eVTOL range. The Lilium Jet is designed to overcome those obstacles. The wing and canard aircraft have a good lift-to-drag ratio, and power requirements are low at cruise speed. Power for both vertical and horizontal flight comes from many small electric motors pushing air through variable nozzle ducts. Electric power comes from 330 Wh/kg density batteries. Service entry will be in the premium sector.

Whisper Aero Set to Reveal Details About Its Ultra-Quiet Propulsion System

Whisper Aero has been working on quiet propulsion technology for two years, looking for a noise reduction of about 20 dB for drones and electric fixed-wing aircraft. The company has provided no specifics but is expected to reveal details about its propulsors “toward the end of March or early April.” They’ve built a 55-pound demonstrator drone to test the concept. Reportedly, the company plans to offer different propulsion system models with different power outputs.

378 UAS Incident Map

An interactive UAS incident map, an airspace coordinator collaborates with archaeologists, a drone swarm that sniffs out gas leaks, the X-56B UAV is destroyed, making drones and air taxis quiet, and AI drones that find meteorites.

Explore Thousands Of FAA Drone And Unidentified Aircraft Incident Reports With Our Interactive Tool

The Drive has taken FAA incident reports of UAS and unidentified aircraft and created an interactive and searchable UAS incident map. The approximately 10,400 incident reports cover the period from November of 2014 until December 2020. Find the UAS incident map at UAV Geography. (Be patient, it can load slowly.)

Pax UAS Airspace Coordinators Collaborate with Local Archaeologists

Historic St. Mary’s City (HSMC) is the earliest settlement in Maryland with a fort erected in 1634. Archeologists working the site considered drones to be part of their archaeological toolkit, but they didn’t have an understanding of the regulatory requirements. Pax River’s then-UAS Airspace Coordinator Air Traffic Controller 1st Class James “Cody” Green stepped in and started working with HSMC to ensure the drone operations were safe and legal.

Swarm of autonomous tiny drones can localize gas leaks

Researchers at the Delft University of Technology Micro Air Vehicle Lab and Harvard University have developed a swarm of tiny drones that can autonomously detect and localize gas sources in cluttered indoor environments. The bio-inspired navigation and search strategy algorithm is called “Sniffy Bug.”

NASA’s X-56B UAV destroyed in crash on 9 July

A “flight anomaly” caused the vehicle to crash. The aircraft was being used to test ways to suppress flutter. It is not clear if other X-56B vehicles exist, or when testing will resume.

Whisper Aero emerges from stealth to quiet drones and air taxis

Startup Whisper Aero believes they can make drones quiet. An electric thruster would reduce the drone’s noise down to background levels that would be difficult for the human ear to hear. Whisper isn’t saying much about their thruster design.

Automated drones being taught to locate fallen meteorites

Less than 2% of meteorites are recovered but University of California, Davis researchers believe they can increase that percentage using AI and automated drones. These would fly in grid patterns at low altitudes over areas where they suspect meteorites have fallen. Images from the UAV would be analyzed by software that employed machine learning to differentiate meteorites from terrestrial rocks.
