NASA Tests CATNLF Wing Design to Cut Fuel Use by 10 Percent
NASA’s CATNLF wing design completed its first flight test, aiming to reduce fuel consumption by up to 10% for future commercial aircraft.
This article is based on an official press release from NASA.
On January 29, 2026, NASA achieved a significant milestone in sustainable aviation by conducting the first successful flight of the Crossflow Attenuated Natural Laminar Flow (CATNLF) wing design. According to the agency, the test took place at the NASA Armstrong Flight Research Center in Edwards, California, utilizing the agency’s F-15B Research Testbed aircraft. This Test-Flights marks the beginning of a comprehensive testing campaign aimed at validating aerodynamic technologies that could drastically reduce fuel consumption for future commercial airliners.
The experimental wing section, a 3-foot scale model, was mounted vertically underneath the F-15B’s fuselage to simulate flight conditions relevant to large transport aircraft. NASA reports that the primary objective of the 75-minute flight was to demonstrate that the specific wing geometry could maintain “laminar” (smooth) airflow over a swept wing, a feat that has historically been difficult to achieve without heavy mechanical systems.
This project is a key component of NASA’s Sustainable Flight National Partnership, which seeks to help the aviation industry reach net-zero carbon emissions by 2050. By refining the shape of the wing to passively control airflow, engineers hope to reduce drag significantly, offering a potential 10% reduction in fuel burn for long-haul jets.
Modern commercial jets utilize swept wings, angled backward from the fuselage, to fly efficiently at high transonic speeds. However, this design introduces a specific aerodynamic challenge known as “crossflow instability.” As air moves across a swept wing, it tends to become turbulent near the leading edge, increasing friction drag and fuel consumption.
According to NASA’s technical overview, the CATNLF design addresses this issue through geometry rather than mechanics. Instead of using heavy suction systems or active control devices to smooth the air, the CATNLF wing features a computer-optimized shape that manipulates air pressure distribution. This “dampens” crossflow instabilities, allowing the air to remain smooth and layered (laminar) over a much larger surface area.
For this specific test series, NASA did not fly a full-sized new aircraft. Instead, they utilized a “scaled wing” test article, a 40-inch tall model attached to the F-15B. This setup allows researchers to expose the model to the high speeds and specific angles of attack experienced by commercial airliners, gathering real-world data to validate computer simulations.
“It was incredible to see CATNLF fly after all of the hard work the team has put into preparing. Finally seeing that F-15 take off and get CATNLF into the air made all that hard work worth it.”
, Michelle Banchy, Research Principal Investigator, NASA Langley
The implications of this research extend well beyond aerodynamic theory. NASA estimates that if the CATNLF technology is successfully scaled up and applied to large, long-range aircraft like the Boeing 777, it could reduce fuel burn by up to 10%. In an industry where fuel costs are a primary operating expense, such an efficiency gain would translate to millions of dollars in annual savings per aircraft.
Furthermore, the environmental impact aligns with global climate goals. A reduction in fuel burn directly correlates to lower carbon dioxide emissions. Mike Frederick, the Principal Investigator at NASA Armstrong, emphasized the cumulative value of these improvements.
“Even small improvements in efficiency can add up to significant reductions in fuel burn and emissions for commercial airlines.”
, Mike Frederick, Principal Investigator, NASA Armstrong
We view the CATNLF project as a critical pivot point for “Green-Aviation.” While much industry attention is currently focused on radical propulsion changes, such as hydrogen or electric powertrains, those technologies remain decades away for long-haul wide-body aircraft. Aerodynamic refinements like CATNLF represent a “near-term” solution that can be integrated into the next generation of conventional tube-and-wing aircraft expected in the 2030s.
Unlike active laminar flow control systems, which require complex maintenance and add weight (often negating some fuel savings), NASA’s passive approach relies entirely on shape. If validated, this could allow Manufacturers to achieve double-digit efficiency gains without increasing the mechanical complexity of the airframe, a highly attractive proposition for airlines focused on reliability and maintenance costs.
The January 29 flight was merely the first of up to 15 planned test flights. NASA has indicated that future sorties will push the test article to various speeds and altitudes to map exactly where and when the laminar airflow breaks down. These data points are essential for refining the design before it can be considered for full-scale commercial production.
The project involves collaboration between NASA Langley Research Center, which led the design refinement, and NASA Armstrong Flight Research Center, which is conducting the flight operations. The ultimate goal is to transition this technology to the commercial sector in time for the next generation of single-aisle and wide-body airliners.

Wave Function Ventures Invests in Natilus Blended-Wing-Body Aircraft
Wave Function Ventures invests in Natilus to support BWB aircraft development, including Kona cargo and Horizon passenger models with strong order backlog.
This article is based on an official press release from Wave Function Ventures and Natilus, with additional context from company reports.
On February 17, 2026, Wave Function Ventures® (WaveFx®) announced a strategic investment in Natilus, the San Diego-based aerospace company designing Blended-Wing-Body (BWB) aircraft. This capital injection is part of Natilus’s Series A funding round, which has raised approximately $28 million to date under the leadership of Draper Associates.
The investment signals growing confidence in hardware-focused “Deep Tech” solutions for aviation sustainability. According to the announcement, the funding will support the manufacturing of Natilus’s regional cargo-aircraft prototype, the Kona, and advance the engineering of its passenger program, the Horizon. By moving away from the traditional “tube-and-wing” design, Natilus aims to deliver aircraft that offer significantly higher internal volume and fuel efficiency while utilizing existing airport infrastructure.
Wave Function Ventures joins a syndicate of investors including Flexport, Type One Ventures, The Veteran Fund, and New Vista Capital. The firm, known for its “atoms over bits” investment thesis, focuses on engineering-led startups solving physical-world problems in aerospace, defense, and energy.
Al Peters, Founder of Wave Function Ventures, emphasized the pragmatic nature of the Natilus design in a statement regarding the investment:
“We see an incredible convergence. It’s smart engineering that helps the planet by cutting emissions while integrating into existing airport infrastructure. Our investment in Natilus supports founders building technology that makes a real difference.”
The partnership aligns with the broader industry push to decarbonize. Aviation currently contributes approximately 3% of global COâ‚‚ emissions, and traditional airframe designs have reached a plateau in efficiency gains. Natilus claims its BWB architecture can reduce emissions by 50% and fuel consumption by 30% compared to current aircraft.
The core of Natilus’s innovation is the Blended-Wing-Body design, where the fuselage and wings merge into a single lifting body. This configuration reduces aerodynamic drag by roughly 30% and provides 40% more cargo volume than traditional aircraft of the same weight class.
Aleksey Matyushev, CEO of Natilus, highlighted the company’s modern approach to development: “Our digital-first engineering approach reduces reliance on costly prototypes without compromising safety. We’re not just designing aircraft, we’re future-proofing logistics.”
According to company data, Natilus is developing two primary aircraft models to address different segments of the market:
Natilus reports significant commercial traction for these models, citing an order backlog of over 570 aircraft valued at more than $24 billion. Commitments have been secured from major operators including Ameriflight, Volatus Aerospace, and Flexport.

The investment by Wave Function Ventures highlights a critical strategic differentiator for Natilus: the decision to prioritize an uncrewed cargo aircraft (Kona) before attempting a passenger liner. By validating the BWB airframe in the cargo market, where regulatory hurdles for autonomy and new airframes may be navigated differently than in passenger travel, Natilus can generate revenue and flight data to de-risk the larger Horizon program.
One of the historical barriers to BWB adoption has been airport compatibility. Radical new shapes often require new gates or hangars. However, Natilus has explicitly engineered its fleet to fit existing gates and maintenance facilities. This “drop-in” capability is likely a key factor driving the $24 billion backlog, as it allows operators to adopt the technology without lobbying for massive infrastructure overhauls at major hubs.
Frequently Asked Questions

Collins Aerospace SkyNook Named 2026 Crystal Cabin Award Finalist
Collins Aerospace’s SkyNook suite, designed to utilize unused aft cabin space, is a finalist for the 2026 Crystal Cabin Awards in Passenger Comfort.
This article is based on an official press release from Collins Aerospace.
On February 17, 2026, Collins Aerospace, a business of RTX, announced that its new cabin concept, the “SkyNook” suite, has been named a finalist for the 2026 Crystal Cabin Awards. Competing in the “Passenger Comfort” category, the product is designed to monetize underutilized space on widebody Commercial-Aircraft while providing enhanced amenities for families, pet owners, and travelers with sensory sensitivities.
The winners of the prestigious awards are scheduled to be announced on April 14, 2026, at the Aircraft Interiors Expo in Hamburg, Germany. According to the company’s announcement, the SkyNook aims to solve a longstanding engineering challenge regarding the tapering fuselage at the rear of aircraft.
The primary engineering innovation behind the SkyNook is its placement. In widebody aircraft, the fuselage narrows toward the tail, often making standard seat rows impossible to install efficiently. This creates gaps between seats and the sidewall, historically referred to as “dead space” or used merely for storage.
Collins Aerospace has developed SkyNook to convert this area into a revenue-generating product. By utilizing this specific footprint, Airlines can offer a semi-private retreat without removing existing revenue seats. In their official statement, the company described the core function of the suite:
“The SkyNook suite transforms unused space into a flexible, semi-private retreat at the aft of a widebody aircraft.”
, Collins Aerospace Press Release
According to the product details released by Collins Aerospace, the suite is modular and includes specific features designed to accommodate passengers who often struggle in standard economy seating. The suite features a convertible console capable of securing various items that are typically difficult to manage in a standard row.
The Manufacturers highlights that the console is explicitly designed to hold: Additionally, the suite includes a deployable privacy divider. This barrier visually separates the occupants from the aisle, providing a shield against the high foot traffic often found near rear lavatories and galleys. This feature is marketed not only for privacy but also as a solution for neurodivergent passengers or those with sensory sensitivities who require a “calm zone” dampened from cabin noise and visual overstimulation.
The Crystal Cabin Awards are widely regarded as the leading international accolade for excellence in aircraft interior innovation. SkyNook’s nomination in the “Passenger Comfort” category places it alongside other major industry players.
According to award nomination details, SkyNook is competing against distinct concepts that highlight different strategies for cabin utilization:
While competitors are refining existing class structures, either ultra-luxury or sustainable economy, Collins Aerospace is attempting to create a new ancillary revenue stream by capitalizing on previously wasted floor space.
The Push for Inclusive Revenue Generation
The nomination of the SkyNook highlights two converging trends in the 2026 Market-Analysis: the aggressive pursuit of ancillary revenue and the demand for inclusive design. Airlines are under immense pressure to maximize yield per square inch of the cabin. Historically, the aft taper has been a liability; Collins Aerospace is proposing a solution that turns this liability into a premium “economy-plus” product.
Furthermore, the explicit inclusion of design elements for service animals and sensory-sensitive travelers suggests a shift in how manufacturers view “comfort.” It is no longer just about legroom; it is about accessibility. By creating a dedicated space for these demographics, airlines can potentially reduce friction in the boarding process and improve the travel experience for passengers with diverse needs, all while charging a premium for a space that was previously empty.

SkyNRG Closes Financing for Europe’s First Standalone SAF Plant
SkyNRG reaches financial close for DSL-01, Europe’s first standalone SAF plant in the Netherlands, targeting full operations by mid-2028.
This article is based on an official press release from SkyNRG and accompanying project documentation.
SkyNRG has officially reached financial close for DSL-01, its first dedicated commercial-scale Sustainable Aviation Fuel (SAF) production facility. Located in Delfzijl, Netherlands, the project marks a significant milestone in the European aviation sector’s transition to renewable energy. According to the company’s announcement, construction on the facility has already commenced, with full operations targeted for mid-2028.
The DSL-01 project is distinguished as Europe’s first standalone greenfield SAF plant, meaning it is being built from the ground up rather than as an expansion of an existing fossil fuel refinery. Once operational, the facility is projected to produce 100,000 tonnes of SAF annually, alongside 35,000 tonnes of by-products including bio-propane and naphtha.
Maarten van Dijk, CEO and Co-Founder of SkyNRG, emphasized the strategic importance of this development in a statement regarding the launch:
“Reaching this important milestone… marks an important step in our transition to becoming an owner and operator of SAF production capacity. This milestone demonstrates growing market confidence in scalable SAF production and provides a model for future sustainable fuel projects globally.” The facility will utilize Topsoe’s HydroFlexâ„¢ technology, operating on the Hydroprocessed Esters and Fatty Acids (HEFA) pathway. SkyNRG has stated that the plant will process waste oils and fats,predominantly sourced from regional industries,and will explicitly exclude virgin vegetable oils such as palm or soy to avoid competition with food supplies. The project aims to deliver a lifecycle CO2 emissions reduction of more than 85% compared to fossil jet fuel.
Technip Energies has been awarded the Engineering, Procurement, and Construction (EPC) contract for the site. While specific contract values are often confidential, industry reports estimate the value between €500 million and €1 billion. The construction phase is expected to generate hundreds of jobs in the Groningen Seaports region, contributing to the area’s developing green industrial cluster.
A critical aspect of the DSL-01 project is its financial structure. It is the first commercial-scale SAF plant to secure non-recourse project financing, a move that signals increasing maturity in the SAF market. Under this structure, lenders are repaid based on the project’s future cash flow rather than the general assets of the parent company.
The investment consortium includes: Arjan Reinders, Head of Infrastructure Europe at APG, noted the alignment of this investment with broader sustainability goals:
“SkyNRG represents the first investment in the SAF sector on behalf of our client [ABP], which is closely aligned with our ambition to create impact by investing at the forefront in energy transition assets.” To ensure the commercial viability of the plant, SkyNRG has secured long-term offtake agreements. KLM Royal Dutch Airlines has committed to purchasing 75,000 tonnes of SAF annually for a period of 10 years. This volume represents three-quarters of the plant’s total SAF output and is essential for KLM to meet upcoming EU mandates under the ReFuelEU Aviation Regulation.
Additionally, SHV Energy has agreed to purchase the bioLPG (bio-propane) by-products produced by the facility. Shell, a strategic partner of SkyNRG since 2019, retains an option to purchase SAF from the plant and continues to provide technical and commercial expertise.
The successful financial close of DSL-01 represents a pivotal moment for the SAF industry, specifically regarding “bankability.” Historically, SAF projects have struggled to attract traditional project finance due to perceived technology and market risks. The willingness of a major banking syndicate to provide non-recourse debt suggests that financial institutions now view HEFA-based SAF production as a stable asset class.
Furthermore, the timing of this project aligns directly with the European Union’s “Fit for 55” regulatory package. With the ReFuelEU Aviation Regulation mandating a 2% SAF blend by 2025 and rising to 6% by 2030, the DSL-01 facility will come online just as demand pressures intensify. Unlike competitors expanding existing refineries, SkyNRG’s success with a standalone greenfield site provides a “proof of concept” that could accelerate the development of similar independent facilities globally, such as their planned projects in the United States and Sweden.
