The aerospace industry uses highly specialized electrical components and integrated assemblies to support the unique demands of each aircraft. These components are essential to ensure safety, efficiency, and performance in extreme temperatures and environments. There are new technologies shaping the field, as well as industry standards that must be met by every component. Let’s explore some of the key components and assemblies used in the aerospace industry.
Critical Electrical Components in Aerospace Applications
Aerospace components must be lightweight, durable, and be able to withstand harsh conditions. Here are the most common electrical components used:
- Wiring and cables: these components transmit power, signals, and data between various components.
- Connectors: The common connectors used are D-sub, circular, and high-density, to link electrical systems and ensure signal integrity and power transfer.
- Relays and contactors: These components are used to control the flow of electricity within a system.
- Circuit protection devices: These include fuses, circuit breakers, and thermal cutoffs, used to prevent short circuits and system failures.
Integrated Assemblies in Aerospace
Integrated assemblies are used to consolidate multiple components into a single unit, which reduces the space needed and the weight of the components. These assemblies have to meet strict regulatory standards and be able to withstand extreme environments. Some of the main assemblies used in aerospace include:
- Avionics control panels: These panels control navigation, communication, and monitoring systems using controls, displays, and data systems designed to allow pilots quick access to critical information and aircraft functions.
- Engine control units (ECUs): These assemblies monitor and control fuel injection, throttle control, and engine performance to adapt to flying conditions in real-time.
- Flight control systems: These controls combine mechanical, hydraulic, and electrical components to manage aircraft movement in various weather conditions.
Standards and Certifications
Electrical components and assemblies made for the aerospace industry must pass rigorous industry standards to ensure safety and reliability. There are many quality requirements across the industry that are unique to aerospace and defense manufacturers and distributors. One of the standards in the aerospace industry is AS9100D, which is an international quality standard for design, development, and production for aerospace manufacturers. In the defense sector, the requirements are very specific including the International Traffic in Arms Regulations (ITAR) regulations to control the import, export, and services related to defense items, and the Defense Acquisition Regulations System (DFARS) requirements which are related to cybersecurity for manufacturers working with the U.S. Department of Defense (DoD).
New Technologies Emerging for Electrical Components
Aerospace manufacturers look for new materials and technology to optimize fuel efficiency and reduce overall weight of parts. Using lighter weight materials like aluminum alloys and carbon composites is one way to maintain design and strength while reducing weight. Using 3D printing is another new technology to create custom components. Another technology being used is Artificial Intelligence (AI) and Machine Learning (ML) which can help manufacturers predict potential failures, improve reliability, and reduce downtime.
