JetZero is developing a new blended wing aircraft suitable for passenger, military, and cargo missions. The project has attracted support from government agencies and civilian airlines. While this new design has great potential and advantages over typical aircraft, JetZero is learning that it must overcome several key disadvantages before beginning production.
JetZero Blended Wing Aircraft to Have Some Similarities to Current Aircraft
JetZero has designed its new blended wing aircraft, the Z4, to carry 250 passengers, similar to the capacity of the Boeing 757. In some ways, it will be quite similar to aircraft flying today. The Z4 can use conventional jet fuel and does not require new engine technologies. The current plans are to power the aircraft with Pratt & Whitney PW2040 engines from the same engine family used in the 757 and the US Air Force C-17 Globemaster.
Better Fuel Efficiency Due to Less Drag and More Lift
The shape of the Z4 fuselage is probably the main difference between the aircraft flying today. As the entire fuselage forms a wing, the aircraft creates less drag and has more lift from the entire wingspan. This feature leads to its most important advantage: better fuel efficiency.
JetZero estimates its blended wing design will result in as much as 50% less fuel use per passenger mile than conventional jets of similar size. For example, a Z4 flight from New York to Palma de Mallorca, Spain, would use 45% less fuel than aircraft currently flying that route.
JetZero Also Expecting Less Emissions From Blended Wing Design
Besides the Z4’s fuel savings, the JetZero blended wing design produces fewer emissions. Part of this is from being more efficient, but they also plan for it to use sustainable aviation fuel (SAF). SAF is manufactured from sustainable feedstocks like used cooking oil, animal waste fat, and solid waste such as packaging materials, paper, textiles, and food scraps. It can also come from forestry scraps like waste wood and energy crops like algae and fast-growing plants.
British Petroleum (BP) is working on SAF. They report that it can be blended 50-50 with other jet fuels and that aircraft require no modifications for commercial use. Some key advantages of using SAF include lowering carbon emissions, reducing particulate emissions by about 90%, and practically eliminating sulfur emissions.
Due to higher production costs, SAF is more expensive than regular fuels. However, several airlines, like United and Delta, aim to become more efficient and achieve net-zero emissions and are willing to move to SAF anyway. While the Z4 can fly with regular fuels, its overall efficiency will improve even more with SAF.
The JetZero blended wing aircraft has attracted strong interest from United and Delta. On 24 April 2025, United announced that it is investing in JetZero and plans to buy 200 Z4s. The deal will require JetZero to reach several development goals, including flying a full-scale demonstration model in 2027.
New Aircraft Must Fit Into Existing Airport Infrastructure
United also wants to ensure that the Z4 blended wing aircraft will fit into existing infrastructure like runways, taxiways, and passenger bridges. JetZero has mentioned this, but has not provided any specific details to confirm it.
Delta also has big plans for the Z4. On 05 March 2025, it announced a partnership with JetZero.
“Working with JetZero to realize an entirely new airframe and experience for customers and employees is bold and important work to advance the airline industry’s fuel-saving initiatives and innovation goals,” said Amelia DeLuca, Delta’s Chief Sustainability Officer.
Another advantage of the Z4 design is that it will be quieter than conventional passenger jets. JetZero’s design has the engines mounted above the wings, which they expect will result in less noise.
A Better Passenger Experience
The company also expects the Z4 to provide a different but better customer experience. The most noticeable difference will be that longer rows will extend across the winged fuselage instead of the several narrow columns from front to back on typical tube-shaped designs. The aircraft might have 15 to 20 rows across the cabin. This layout will allow for larger seats, more dedicated overhead space for belongings, and even a wider main door, making embarkation and debarkation easier.
Pressurization Biggest Hurdle For JetZero
Despite these advantages, JetZero faces several serious obstacles in developing its blended wing aircraft. The most challenging of these involves pressurization. On a typical passenger jet, the pressure is evenly distributed throughout the length and consistent width of the fuselage.
With its irregular interior shape, a blended wing aircraft finds it more challenging to distribute and maintain equal pressure in the cabin. JetZero states it will overcome this with new composite materials.
Patents May Indicate JetZero Solved Pressure Concerns
It also claims it has intellectual property that addresses the pressurization issue but has not provided any details. This possible solution might include several patents it recently received, one for a mold for aircraft components and another for carbon fiber materials and manufacturing processes.
JetZero has several other engineering challenges to overcome. These include issues with low-speed handling on takeoffs and landings and working with an overall more complex design.
US Air Force Makes Big Investment in JetZero Blended Wing Aircraft.
The hope is that the Z4 blended wing aircraft will not be limited to commercial travel. In 2023, the US Air Force invested $235 million in the aircraft. Besides the obvious fuel efficiency, the service also cited the potential for the design to be used for tanker and cargo missions.
