What’s Next for Jet Engines? Emerging Technologies and Trends

Jet engines have long been a cornerstone of modern aviation operations, powering everything from spacious commercial airliners to acrobatic military aircraft. Continued technological advancements over the years have made these engines increasingly powerful, efficient, and reliable, with the industry furthering its push to reach new boundaries of potential. In this blog, we will explore some of the most significant emerging technologies and trends that are shaping the next generation of jet engines and beyond, covering topics like advancements in propulsion, manufacturing techniques, and the push for supersonic flight.

New Propulsion Technologies for Jet Engines

As the aviation industry seeks more sustainable and efficient methods for powering aircraft, several new propulsion technologies are gaining traction. The innovations shared below are examples of those that focus on reducing fuel consumption, emissions, and noise while increasing overall engine performance.

• Adaptive Cycle Engines: One of the most promising developments in jet engine technology is the adaptive cycle engine that allows for switching between different operating modes based on flight phase. This facilitates optimal fuel efficiency during cruise conditions and enhanced performance during takeoff or combat scenarios.
• Electric Propulsion: Although a technology still in its infancy, electric engine systems are a rapidly developing area in aviation that has the potential to significantly reduce reliance on traditional fossil fuels. Though electric propulsion is not yet widely adopted for large aircraft, hybrid-electric engines are being researched as a potential solution for smaller planes and urban air mobility vehicles at this time. This propulsion method also reduces noise and emissions while providing high efficiency, making it a strong candidate for future designs.
• Artificial Intelligence (AI): As a last example to answer the question of what is new jet technology, AI is increasingly being implemented across engine systems to monitor and optimize performance in real-time. This AI can allow for the prediction of mechanical wear and make automatic adjustments as necessary, improving safety, reducing maintenance costs, and maximizing fuel efficiency.

Modernized Manufacturing Technologies and Techniques

Various advances in manufacturing technologies and production methods are also making modern jet engines more efficient, lighter, and safer, including:

• 3D Printing: Also known as additive manufacturing, 3D printing is transforming how jet engines are designed and produced. This technology is enabling manufacturers to design and create engine components that would otherwise be impossible or extremely difficult to make using traditional methods. Additionally, 3D printing has the potential to simplify supply chains as a result of on-demand manufacturing capabilities.
• Advanced Composite Materials: Jet engines are increasingly being manufactured with advanced composite materials like carbon fiber-reinforced polymers to achieve lighter assemblies that are still rigid and robust. Additionally, many composite materials offer superior resistance to heat and fatigue, furthering engine longevity while reducing maintenance costs.

What Technologies Are Being Researched That Can Improve the Turbine Engine?

One of the most exciting frontiers in jet engine development at this time is the returned push toward supersonic flight. After the famous Concorde airliner was retired in 2003, supersonic travel took a backseat to more efficient and quieter subsonic flight. However, renewed interest in faster air travel is driving the development of modernized supersonic engines that can achieve speeds greater than Mach 1 while meeting current industry objectives and expectations.

To address concerns that led to the retirement of the Concorde, engineers are working on creating new supersonic engines that are fuel-efficient and quieter than their predecessors. Fuel efficiency is a particular challenge, as these engines often consume large volumes to obtain the thrust and power necessary for supersonic speeds. By leveraging modern materials, technologies, and design techniques, manufacturers are closer to making supersonic flight commercially viable once again.

Outlook for the Future of Jet Engine Technologies

After covering these emerging technologies and trends, one may still ask, “What is next for jet engines?” As the aviation industry continues to evolve and electrify, jet engines will still remain a staple of air travel. However, they are expected to become more efficient, sustainable, and versatile through the integration of cutting-edge technologies.

• Autonomous Aircraft: As autonomous aircraft technologies advance, future jet engines will need to be even more intelligent with the ability to self-monitor and adjust operations for various conditions. Future autonomous systems will heavily rely on engines equipped with advanced sensors and artificial intelligence capabilities for optimal performance, driving investment in such fields.
• Hybrid Propulsion Systems: Before electric propulsion systems become more widespread, the future of jet engine technologies will likely see a shift toward hybrid propulsion systems that combine traditional fuel-based engines with electric propulsion. By integrating electric engine systems with conventional jet engines, these aircraft could optimize fuel consumption during different phases of flight, such as using electric power for takeoff and landing while relying on jet fuel for cruising. This approach could significantly improve fuel efficiency, reduce emissions, and lower operating costs, all while maintaining the performance needed for long-distance travel.
