美空军重视“下一代空中优势”战机数字工程与模拟仿真,加快新概念及样机设计(英文)

据 Jane’s Defence Weekly2019年8月10日报道,美国空军越来越重视“下一代空中优势”(NGAD) 战机的数字设计模拟仿真,加快新概念及技术的样机设计和实验验证工作,以缩短研制周期、减少经费开支。8月7日,美空军采办、技术与后勤副部长办公室主任戴维•克鲁姆透露,数字工程和模拟仿真将深化部队对产品在设计阶段乃至生产和维持阶段的评估,模拟仿真将促进空军加强能力和系统的设计开发,以紧跟技术迅速发展的步伐。“下一代空中优势”战机将作为实验美空军技术突破和概念革新的重要平台,验证其在未来同级冲突中克敌制胜的作战能力。

Key Points

  • A US Air Force official expects more modelling and simulation work with its Next Generation Air Dominance effort.
  • This would enable the service to rapidly experiment with new concepts or technologies and to spend less time and money building and testing physical models.

An increased emphasis on digital design modelling and simulation (M&S) with Next Generation Air Dominance (NGAD) will enable the US Air Force (USAF) to rapidly prototype and quickly experiment with different capabilities and designs, according to an official.

Major General David Krumm, office of the assistant secretary of the Air Force for Acquisition, Technology, and Logistics (AT&L), director of global power programmes, said on 7 August that digital engineering and M&S will enable the service to evaluate items not only in the design phase but also in the production and sustainment phases. M&S, he said, will enable the USAF to design capabilities and systems that are rapidly updatable and modular so that the air force can keep pace with rapidly advancing technologies.

“We have to be able to do this on a quick cycle [which is] why we are so excited about digital engineering and digital acquisition,” Maj Gen Krumm said at an Air Force Association (AFA) event.

NGAD is the USAF’s experimentation with groundbreaking technologies and radical concepts to figure out the capabilities needed to prevail in a future peer-level conflict. The air force is trying to determine what evolutionary developments will be critical in the 2030s and beyond if it wants to dominate heavily guarded airspace defended by nations such as China or Russia.

The USAF’s experimentation with the Advanced Battle Management System (ABMS) will also be important to concepts developed with NGAD. Originally promoted as the replacement for the cancelled Joint Surveillance Target Attack Radar System (JSTARS), ABMS and NGAD revolve around the ability to seamlessly and ubiquitously share information in a robust and reliable fashion.
