The Defense Advanced Research Projects Agency (DARPA) and Dynetics have achieved a significant milestone with the development of the new unique Gremlins air vehicle.
美国国防高级研究计划局(DARPA)和Dynetics通过开发新型独特的Gremlins飞行器实现了一个重要的里程碑。
Dynetics announced that the new X-61A Gremlins Air Vehicle (GAV) had successfully performed its maiden flight in November 2019.
Dynetics宣布，新的X-61A Gremlins航空器(GAV)在2019年11月成功地进行了首次飞行。
The test took place at Dugway Proving Ground near Salt Lake City, Utah.
测试在犹他州盐湖城附近的Dugway试验场进行。
Testing operations involved one captive-carry mission aboard a TBM, Inc.
测试行动包括一艘TBM，Inc.上的一次俘虏携带任务。
C-130A and an airborne launch and free flight of the X-61A that lasted one hour and 41 minutes.
C-130A和X-61A的空中发射和自由飞行持续了1小时41分钟。
The test objectives included:
测试目标包括：
The X-61A flew as predicted with no anomalies, achieving all test objectives that relate to the operational system.
X-61A按预期飞行，没有异常，实现了与操作系统相关的所有测试目标。
At the end of the mission, the engine was shut down and a drogue chute successfully deployed to terminate flight.
在任务结束时，发动机被关闭，并且成功地部署了减速降落伞以终止飞行。
Unfortunately, the vehicle was lost during the ground recovery sequence due to a failure to extract the main chute.
不幸的是，由于无法提取主滑道，车辆在地面恢复序列中丢失。
Managed out of DARPA’s Tactical Technology Office (TTO), the overarching goal of Gremlins is to accelerate the ability to perform aerial launch and recovery of volley quantities of low-cost, reusable unmanned aerial systems (UASs).
由DARPA战术技术办公室(TTO)管理，Gremlins的总体目标是加快执行空中发射和回收大量低成本、可重复使用的无人航空系统(UAS)的能力。
