GE Aerospace Teams with Kratos to Build Small Engines for Collaborative Combat Aircraft

Posted by Dronerator
In early June, GE Aerospace’s Defense & Systems division signed a formal teaming agreement with Kratos Defense & Security Solutions to put performance and affordability into a small and mighty package: the high-thrust turbofan propulsion systems for the next generation of unmanned aerial vehicles (UAVs). The latest such engine — able to deliver 1,500 pounds of thrust — belongs […]

ZeroAvia Certification-Intent Fuel Cell System Successfully Replicates Full Flight Profile in Ground Test

Posted by Dronerator
– ZeroAvia has announced that it has completed a full flight profile ground test of its certification-intent low temperature proton exchange membrane (LTPEM) fuel cell power generation system (PGS) for the ZA600 hydrogen-electric powertrain. The test simulated a 250 nautical mile flight in a Cessna Caravan 208b aircraft, equivalent to flying between London Heathrow and […]

Piezoelectric Energy Harvesting in Quadcopter UAVs

Posted by Dronerator
Unmanned Aerial Vehicles play a crucial role across multiple sectors, particularly in tasks like surveillance and reconnaissance . As the demand for longer flight times and increased autonomy continues to grow, one of the primary challenges is ensuring a reliable and sufficient power supply for the onboard systems. Conventional battery power sources often present limitations […]

Heven Demonstrates Fuel Cell UAV Flight at 12,000 ft

Posted by Dronerator
– Zepher Flight Labs (ZFL), a Heven company, announced that its hydrogen fuel cell-powered Z1 successfully demonstrated a vertical takeoff at maximum takeoff weight (MTOW), followed by a continuous 11,000-foot climb to a density altitude (DA) of 12,000 feet during the intelligence, surveillance, and reconnaissance (ISR) mission phase. Part of Heven’s next-generation portfolio, the Z1 is […]

Joby Hydrogen-Powered Autonomous Aircraft Emerges After Apparent 9-Hour Flight

Posted by Dronerator
On a scorching summer afternoon on a windswept airport tarmac in Eastern Oregon, an unusual aircraft became the center of bustling activity.  Its shape was distinctive: squat and bulbous, almost egg-like, yet balanced by gracefully extended wings. It sat quietly amid a hive of ground crew members who hurried around it. Nearby, a hydrogen tank […]

ZeroAvia Gets UK Government Grant for Development and Flight Test of Liquid Hydrogen Fuel System

Posted by Dronerator
– ZeroAvia has announced the UK Government has awarded the company and consortium partners a grant towards a £10.8m project to develop a novel liquid hydrogen management system. The project, co-funded through the ATI Programme, will culminate in integration of the lightweight fuel system into a Dornier 228 before a series of flight tests. The […]

US Air Force Reaper Drones to Test New Anti-Hacking Software

Posted by Dronerator
The computer code that runs the MQ-9 Reaper will be overhauled in the next two years to test revolutionary new tools that would make its software ‘much, much harder to hack.’ A strong, lethal military demands cutting-edge and resilient software to power every weapon and support system our U.S. warfighters depend on. However, the Department […]
