Impossible Aerospace US-1 makes long-distance flight over Nevada salt flats

2019-08-20
During a public demonstration, an unmodified production Impossible Aerospace Corporation’s US-1 quadcopter, carrying both a FLIR Duo Pro R thermal camera and HD video transmitter, crossed Nevada’s “playa,” or salt flats. In repeated 72-minute flights, the unmanned aircraft system (UAS) flew with and against prevailing winds, covering distances of 29 and 21 miles, respectively.

New Boeing facility will improve V-22 quality, safety

2019-08-06
Outside of Philadelphia, a 350,000-square-foot facility has been transformed into a modern factory where the Boeing Company will build fuselages for the Bell Boeing V-22 Osprey aircraft. The updated plant will also modernize current MV-22 aircraft for the U.S. Marine Corps fleet.

LiDAR Technologies and Systems

2019-07-10
Why are vision systems fundamental and critical to autonomous flight? What are the vision system tasks required for autonomous flight? How can those tasks be approached? It addresses the role of vision systems for autonomous operations and discusses the critical tasks required of a vision system, including taxi, takeoff, en-route navigation, detect and avoid, and landing, as well as formation flight or approach and docking at a terminal or with other vehicles. These tasks are analyzed to develop field of view, resolution, latency, and other sensing requirements and to understand when one sensor can be used for multiple applications. Airspace classifications, landing visibility categories, decision height criteria, and typical runway dimensions are introduced. The book provides an overview of sensors and phenomenology from visible through infrared, extending into the radar bands and including both passive and active systems.

CityAirbus urban air mobility vehicle completes first flight

2019-05-06
According to Airbus, the CityAirbus UAM vehicle – or “air taxi” – will initially be operated by a pilot for certification and market entry purposes; however, the aircraft is designed for fully autonomous flight once regulations are established.
