Air Force tests fully autonomous UAS control system

2019-03-12
The United States Air Force’s 412th Test Wing’s Emerging Technologies (ET) Combined Test Force (CTF) completed the first flight test of Johns Hopkins University’s Testing of Autonomy in Complex Environments (TACE) system. As “middleware,” TACE serves as an “autonomy watchdog,” monitoring commands sent to an aircraft’s autopilot software from its autonomous artificial intelligence (AI) computer and transmitting autopilot information such as position, speed, and orientation back to the AI.

Advanced simulation using the digital twin to achieve electromagnetic compatibility and electrification management in a modern UAS

2022-01-13
The aerospace industry is facing immense challenges due to increased design complexity and higher levels of integration, particularly in the electrification of aircraft. These challenges can easily impact program cost and product time to market. System electrification and electromagnetic compatibility (EMC) have become critical issues today. In the context of 3D electromagnetics, EMC electromagnetic compatibility ensures the original equipment manufacturer (OEM) that radiated emissions from various electronic devices, such as avionics or the entire aircraft for that matter, do not interfere with other electronic products onboard the aircraft.

Advances in Electric Propulsion

2017-05-18
Aviation propulsion development continues to rely upon fossil fuels for the vast majority of commercial and military applications. Until these fuels are depleted or abandoned, burning them will continue to jeopardize air quality and provoke increased regulation. With those challenges in mind, research and development of more efficient and electric propulsion systems will expand. Fuel-cell technology is but one example that addresses such emission and resource challenges, and others, including negligible acoustic emissions and the potential to leverage current infrastructure models. For now, these technologies are consigned to smaller aircraft applications, but are expected to mature toward use in larger aircraft. Additionally, measures such as electric/conventional hybrid configurations will ultimately increase efficiencies and knowledge of electric systems while minimizing industrial costs.

Persistent Systems Auto-Tracking Antenna System adds aircraft to network, enhances data sharing

2018-07-12
The Auto-Tracking Antenna System, a new portable, ground-to-air antenna from Persistent Systems LLC in New York, incorporates aircraft into the Wave Relay mobile ad hoc network (MANET) to boost connectivity, communications, and distribution of critical sensor data, including full-motion video, on the networked battlefield. The precisely aimed tracking system works with the MPU5 radio and Wave Relay MANET to optimize connectivity and reliable communications to enable manned and unmanned aircraft to communicate further than ever before, officials say.
