The Future of Blended-Wing Aircraft: JetZero’s “Jetliner” Leading the Way
For the past 75 years, the design of jet aircraft has remained largely unchanged, with the traditional tube-and-wing configuration dominating the industry. However, as the world becomes increasingly concerned about climate change and the impact of carbon emissions, the aviation industry is seeking more efficient and environmentally friendly alternatives. This is where blended-wing aircraft come into play, offering a revolutionary design that promises to reshape the future of commercial aviation. JetZero, a pioneering company in the field, is currently working on a blended-wing design called the “Jetliner” that is set to revolutionize the industry.
Airlines have always been on the lookout for more efficient aircraft, but now the focus is shifting toward low-carbon or even zero-emission jets. The blended-wing airframe, with its ultra-efficient design, provides a platform that is agnostic to future propulsion solutions, making it compatible with various types of propulsion technology. This flexibility reduces the cost of ownership, enabling a wider adoption of new propulsion systems and paving the way for zero-carbon emissions aviation. JetZero aims to collaborate with key entities like the US Air Force, NASA, and the FAA to bring their innovative Blended Wing Body jet into service by 2030.

The JetZero Blended Wing represents a monumental leap in commercial aircraft architecture since the advent of the jet age and serves as a significant step toward achieving the ultimate goal of zero-carbon emissions aviation. Scheduled to launch in 2030, the Jetliner will be equipped with 100% Sustainable Aviation Fuel (SAF) compatibility and will have the internal volume necessary to accommodate zero-carbon emissions hydrogen. This forward-looking approach ensures that the aircraft is future-proofed, capable of adapting to evolving environmental regulations and technological advancements.
One of the most remarkable aspects of the blended-wing design is its exceptional aerodynamic efficiency compared to traditional tube-and-wing aircraft. The latter designs inherently require large tail surfaces to maintain stability, which adds weight and increases drag. In contrast, the blended-wing configuration is naturally stable and does not require tail surfaces, eliminating unnecessary complexity. By blending the fuselage and wing together, the aircraft achieves lift while reducing the required surface area, resulting in a lighter aircraft with significantly reduced drag.
Moreover, the efficiency gains of the blended-wing design are not limited to aerodynamics alone. The compounding effect of reduced drag and weight leads to a further reduction in engine size, which, in turn, reduces both drag and weight. Consequently, the Jetliner can offer a passenger capacity and range comparable to that of a small wide-body aircraft while utilizing engines similar to those found on existing narrow-body planes. This breakthrough fills the mid-market gap, providing an aircraft that achieves approximately half the fuel burn and emissions of the aging fleet it aims to replace.
While the prospects for blended-wing aircraft like the JetZero Jetliner are undoubtedly promising, there are some challenges and considerations to be aware of. First and foremost, the implementation of a new aircraft design requires significant investment and regulatory approvals. The timeline for entry-into-service by 2030, as targeted by JetZero, depends on successful collaboration with various industry stakeholders and adherence to rigorous safety and certification processes.

The future of aviation lies in the development of more efficient and environmentally friendly aircraft, and blended-wing designs like JetZero’s Jetliner are at the forefront of this transformation. By leveraging an ultra-efficient Blended Wing Body configuration, these aircraft offer unparalleled aerodynamic efficiency, reduced carbon emissions, and the potential for future propulsion system advancements. While challenges exist, the industry is moving toward a greener future, and the Jetliner represents a major step in achieving zero-carbon emissions aviation. With continued innovation, collaboration, and regulatory support, blended-wing aircraft have the potential to reshape the skies and contribute significantly to a sustainable future for commercial aviation.
While JetZero is one of the companies leading the way in blended-wing aircraft development with its Jetliner, there are several other players in the field working on similar concepts. Here are a few concurrent companies and their blended-wing aircraft projects:
Boeing has been actively exploring blended-wing designs for several years. They have conceptualized a blended-wing body aircraft known as the “Transonic Truss-Braced Wing” (TTBW). This concept aims to improve fuel efficiency and reduce emissions by incorporating a highly efficient wing design with a wider fuselage for enhanced aerodynamics.
Airbus has also shown interest in blended-wing aircraft. Their concept, known as the “MAVERIC” (Model Aircraft for Validation and Experimentation of Robust Innovative Controls), features a blended-wing configuration with a wider fuselage. The MAVERIC project aims to explore new possibilities in aerodynamics, efficiency, and passenger experience.
Northrop Grumman is known for its expertise in military and aerospace technologies. They have been developing a blended-wing unmanned aerial vehicle (UAV) called the “X-47B.” While primarily designed for military applications, this aircraft demonstrates the potential of blended-wing designs in terms of range, endurance, and payload capacity.
The National Aeronautics and Space Administration (NASA) has been conducting research on blended-wing designs as well. Their “X-48” project involved the development of a blended-wing body experimental aircraft to investigate its aerodynamic performance, handling qualities, and structural integrity.
