HALE

An unmanned, solar-powered aircraft designed for high-altitude communications has edged closer to the real-world applications, with the HAPSMobile Sunglider successfully completing another round of flight testing in New Mexico.

Looking to give high altitude long endurance (HALE) UAVs the ability to stay in the air for much, much longer – even years at a time – California-based Alta Devices has just released its Anylight Solar for HALE product.

Northrop Grumman has announced that it will send a variant of the Global Hawk UAS into Arctic skies.

Germany's DLR Institute of Robotics and Mechatronics flew its unmanned solar-powered ELHASPA aircraft for the first time this month.

Northrop Grumman's Block 40 Global Hawk has new eyes.

Lockheed Martin yesterday launched the first-of-its-kind High Altitude Long Endurance-Demonstrator (HALE-D) lighter-than-air-aircraft to test a number of key technologies critical to development of unmanned airships.

In a setback for AeroVironment's four-year Global Observer demonstrator program, the first Global Observer unmanned aircraft system has crashed during flight-testing.

The Global Observer unmanned aircraft has taken to the skies for the first time using hydrogen-fueled propulsion.

The Fédération Aéronautique Internationale has ratified the three world records claims made by QinetiQ in July 2010 after its Zephyr UAV stayed airborne for over 14 days.

As part of the second phase of DARPA’s Vulture program, Boeing will develop a full-scale solar-powered demonstrator called the SolarEagle that will make its first demonstration flight in 2014.

QinetiQ has filed for three world records for Zephyr, its solar powered high-altitude long endurance (HALE) Unmanned Air System (UAS) that stayed aloft for 14 nights.

AeroVironment’s Global Observer unmanned aircraft system (UAS) has successfully completed its first flight.
