How to balance the size and material of RF cables and connectors for avionics?(2

In flight, extremely high vibration can put pressure on the circuit board hardware. Interconnect systems need to minimize the space between cables and connectors to withstand high vibrations.

Draw inspiration from commercial aerial innovation

Urban Air Transportation (UAM) is a concept of a safe and efficient air transportation system that will use highly automated aircraft to operate and transport passengers or cargo in low-altitude areas in cities and suburbs. Most UAM vehicles will operate below 10,000 feet, and battery power limits their altitude and endurance. With the development of technology, the density of UAMs in motion will increase, and in a situation called “swarming”, their ADS systems will need to communicate continuously to avoid collisions. These systems rely heavily on antennas and high-frequency transceivers to enable sensors to communicate with each other, so low-loss, reliable, and lightweight cables are essential for reliable communication.

Further developments include advanced air traffic (AAM) solutions, which are based on the UAM concept and whose applications will operate outside of urban environments, from delivery drones to electric vertical take-off and landing (eVTOL) applications . Like electric vehicles, eVTOL control devices run on on-board power and the battery is heavy, so weight is an important consideration. Therefore, these technologies require advanced solutions to meet new requirements, while adhering to the size and weight principles that have dominated their predecessors for decades.

UAV avionics

Another rapidly growing field of avionics is the unmanned aerial vehicle (UAV) field. Some drones are fairly simple and use a single data link, which requires a relatively simple RF interconnection solution. However, with the introduction of hypersonic technology, some of these drones have speeds as high as Mach 5, which increases the requirements for high temperatures. The higher the altitude, the higher the speed, the higher the frequency, and the more complicated the problem from the material point of view. These problems can be solved by dielectrics; in addition, it is also possible to use quartz materials as dielectrics for hypersonic applications.

Ultimately, the person designing the structure needs to understand the environment, the height requirements of the drone, what life expectancy is needed, how often maintenance is allowed, and what test environment is available. For example, will drones carry electronic warfare (EW) systems or electronic intelligence systems, or will the payload be purely data links and video?
