A160 Hummingbird
The Boeing A160 Hummingbird (military designation: YMQ-18A) is an unmanned aerial vehicle (UAV) helicopter. Its design incorporates many new technologies never before used in helicopters, allowing for greater endurance and altitude than any helicopter currently in operation. The development of Hummingbird was begun for DARPA by Frontier Aircraft in 1998. From 2003 both the US Army and the US Navy also shared in funding the project. In May 2004, the company was acquired by Boeing and became integrated into Boeing Phantom Works and then into the Advanced Systems group of Boeing Integrated Defense Systems. Early A160s were powered by modified Subaru automotive engines, but newer versions use Pratt & Whitney Canada PW200, Pratt & Whitney PW207D turboshaft engines. The A160 continued with developmental flight tests in 2010, but test flights had already demonstrated greater endurance, higher altitudes, more extensive autonomy, and greater payload. The program had ambitious goals of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV) or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers onboard, but rather is controlled remotely or is autonomous.De Gruyter Handbook of Drone Warfare; 2024. e-ISBN (PDF) 978-3-11-074203-9.H. Pan; M. Zahmatkesh; F. Rekabi-Bana; F. Arvin; J. HuT-STAR: Time-Optimal Swarm Trajectory Planning for Quadrotor Unmanned Aerial Vehicles IEEE Transactions on Intelligent Transportation Systems, 2025. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage,F. Rekabi-Bana; Hu, J.; T.
