Introduction to AI in aerospace engineering
Artificial Intelligence (AI) has become essential in aerospace engineering. It improves fuel efficiency, part design, maintenance, and enables autonomous operations. In 2023, this evolution is accelerating as engineers and companies integrate AI to meet rising demands. From self-flying air taxis to AI-driven maintenance processes, AI in aerospace engineering is making air travel safer and more efficient. With continuous advancements, AI will reshape the industry further, opening doors to previously unimaginable innovations.
AI Unlocks New Potential in Aerospace Engineering
One major use of AI in aerospace is developing autonomous aircraft. Manufacturers integrate AI into vision systems, sensors, and feedback loops to monitor flight data like wind, weather, and air traffic. This integration enhances aircraft navigation, decision-making, and safety, allowing aircraft to adapt to different conditions and improving flight reliability. Moreover, AI’s application in aerospace engineering is transforming the industry, making it safer and more dependable.
Advanced AI Projects in Aerospace
Kyriakos Vamvoudakis, a researcher from Georgia Tech, works on projects that use reinforcement learning for autonomous land vehicles. Engineers can adapt these projects for aircraft. By learning from human behavior, the AI makes better decisions when handling turbulence or emergency landings, allowing aircraft to operate safely under various weather conditions. This capability reduces the workload of engineers, enabling them to focus on more complex challenges. Consequently, the integration of AI makes aerospace systems more resilient, enabling them to handle diverse scenarios effectively.
For instance, reinforcement learning helps aircraft make real-time, data-driven decisions. An AI-equipped aircraft can autonomously choose a safer flight path during turbulent weather, thus preventing accidents and ensuring a smoother flight experience for passengers. As a result, the aviation industry benefits from improved safety and reduced operational risks.
The Race for Self-Flying Air Taxis
Self-flying air taxis, also called passenger drones, are gaining attention. Companies are developing these aircraft to offer safe, efficient, and cost-effective transport for passengers and cargo. These innovations could reduce urban congestion and travel time. Notably, EHang in China, Wisk in California, and Reliable Robotics, which partners with Cessna, lead the charge in creating autonomous air taxis. AI enables these air taxis to autonomously handle takeoff, flight, and landing, ensuring a higher level of safety and adaptability.
AI processes real-time data and makes immediate decisions, a feature crucial for navigating complex urban environments and handling sudden changes in weather or air traffic. For example, an AI-powered air taxi can alter its flight path to avoid collisions, thereby improving safety for passengers and people on the ground. Therefore, AI’s role in these aircraft is vital for ensuring their reliability and efficiency.
Innovations Supporting Aerospace Engineering
Aurora Flight Sciences, a Boeing subsidiary, is pioneering projects that showcase AI’s role. The Centaur aircraft, for example, is designed for optional piloting. It autonomously takes off, flies, and lands, even when communication with human operators is lost. This capability makes Centaur ideal for extended, unmanned missions lasting up to 16 hours. The system can make decisions autonomously when faced with unexpected situations, enhancing mission success rates. In turn, this feature provides more confidence in the reliability of unmanned operations.
MIDAS, another Aurora project, is an AI-powered counter-unmanned aircraft system. This system uses deep learning and computer vision to detect and defeat small drones autonomously. This capability enhances security and defense operations and builds confidence in automated systems. By using AI, MIDAS can operate with increased reliability, ensuring that important tasks are completed without human oversight. Consequently, this project highlights AI’s importance in protecting vital assets and managing threats.
Aurora also developed the Advanced Teaming Integration Lab (ATIL), a hardware-in-the-loop simulator. ATIL bridges the gap between simulation and actual flight tests, allowing rapid development and testing of multi-vehicle systems. Engineers can fine-tune prototypes before real-world deployment, significantly reducing time and costs. Additionally, the simulation approach improves the success of live tests, contributing to more efficient production cycles.
AI’s Influence on Maintenance, Repair, and Overhaul (MRO)
AI is transforming maintenance practices through digital MRO. General Electric (GE) uses AI to manage its fleet of 70,000 jet engines. AI analyzes real-time data from engines, predicting maintenance needs and preventing unexpected failures. This reduces downtime and enhances safety. Moreover, the system creates an efficient maintenance schedule, maximizing each engine’s lifespan and performance. Digital MRO has become crucial for reducing costs and improving aircraft fleet reliability.
AI’s role in optimizing maintenance also ensures that jet engines receive timely servicing, avoiding delays that could disrupt airline schedules. In this way, GE has improved operational efficiency using AI, benefiting both the company and its customers.
How AI Changes the Role of Engineers
AI reshapes engineers’ roles by automating certain tasks and enhancing design capabilities. Engineers can now focus on complex problem-solving while AI handles repetitive tasks. For example, AI systems detect structural issues, suggest design changes, and optimize flight routes, reducing human error and boosting safety. As a result, engineers have more time to refine designs and develop innovative solutions that push the boundaries of aerospace technology.
Cyber-Physical Security and Mission Completion
Vamvoudakis’ research includes empowering drones with AI for fast decision-making, enabling them to respond to cyber-physical attacks. The AI ensures rapid action and mission completion under challenging conditions. Funded by a $700,000 grant from the U.S. Department of Defense, this work highlights AI’s role in strengthening operational security. In this way, AI enhances cybersecurity and helps drones perform reliably, even under attack.
Vehicle-Agnostic AI: Accelerating Innovation
Aurora Flight Sciences also employs a vehicle-agnostic approach, allowing AI developed for one aircraft model to be adapted for others. This flexibility accelerates prototype development and testing, reducing variability and risk. Engineers can more efficiently test propulsion systems and new configurations, minimizing the time needed to design and deploy new aircraft and speeding up innovation cycles.
Human-Machine Teaming: The Next Frontier
Human-machine teaming improves the collaboration between pilots and AI systems. This approach enhances control and adaptability during complex flights. AI helps pilots regain control when significant changes occur in vehicle behavior, ensuring smoother operations. Aurora emphasizes pairing experienced pilots with AI to enhance safety and build trust. This collaboration helps pilots adapt and make better decisions in unpredictable scenarios, contributing to safer, more reliable flights.
Conclusion
The integration of AI in aerospace engineering sets new benchmarks for the industry.
