“…In the case of UAM, the weight is estimated to be around 600 kg, which is the equivalent of a manned rotary aircraft. Third is another UAM classification method that classifies aircrafts according to the shape of the wings [14]. Figure 2 shows that this classification is based on the shape of the wings as defined on the TransportUP website, and UAM classification is possible in an intuitive manner.…”

This paper presents an open innovation strategy by identifying the patent impact index and cooperation network through patent analysis for leading companies developing technology in the UAM field. Among companies developing UAM technology, patent analysis was conducted on the leading companies with active patent activities, technology classification was used to match companies by parts, and a technical capability index was utilized to identify the companies. When developing UAM technology in the future, this can help companies seek effective partners to improve competitiveness in technology development. To the best of our knowledge, the work done in this paper is unprecedented, as it suggests methods for patent analysis and verifies them by analyzing the UAM patents with the proposed method.

“…The increasing complexity of the electromagnetic environment within aircraft can be attributed to the utilization of composite materials in contemporary aircraft structures, as well as the continuous expansion of onboard electronic systems [2,3]. Additionally, the existence of an external lightning environment presents a heightened potential for adversely impacting the performance of the electronic equipment installed onboard [4]. The effects of lightning on aircraft are categorized into direct and indirect effects.…”

In order to analyze the interference mechanisms of indirect lightning effects on a low-noise amplifier (LNA), a circuit model of the LNA was constructed based on the advanced design system 2020 (ADS 2020) software. Lightning pulse injection simulations were conducted to explore the influence of lightning pulses on the performance of the LNA. A pin injection test was performed to investigate the interference and damage threshold of the LNA. A protective circuit incorporating the transient voltage suppressor (TVS) and Darlington structure was designed through simulation, employing the ADS 2020 for the LNA. The research findings reveal that the interference threshold for the LNA is 60 V, while the damage threshold is determined to be 100 V. The protective circuit demonstrates a measured insertion loss of 0.1 dB, a response time of 1.5 ns, and a peak output voltage of 20 V. The research results indicate that the protective circuit can effectively reduce the impact of lightning’s indirect effects on the LNA. In the future, we will continue the design work of the protective circuit and proceed with physical fabrication and experimental validation.
