Russia’s SJ-100 Passes Key Water Ingestion Test for PD-8 Engines
Russia’s SJ-100 aircraft passed critical water ingestion tests with PD-8 engines, marking progress toward aerospace independence and certification by 2025.
In the high-stakes world of civil aviation, the path from design to commercial flight is paved with rigorous testing. For Russia’s SJ-100 Commercial-Aircraft, a recent milestone marks a significant stride forward in its national ambition to achieve technological independence in the aerospace sector. The aircraft, powered by the newly developed, domestically produced PD-8 engines, has successfully passed a critical water ingestion test. This isn’t just a routine check; it’s a validation of Russia’s capability to build a reliable, modern regional jet using its own technology, a crucial goal in light of international sanctions that have restricted access to foreign components and systems.
The SJ-100, formerly known as the Sukhoi Superjet 100, has been systematically re-engineered to replace imported parts with domestic alternatives. The “heart” of this transformation is the PD-8 engine, a product of the United Engine Corporation (UEC), a subsidiary of the state-owned Rostec corporation. The successful completion of the water ingestion trials confirms that the aircraft’s propulsion system can withstand adverse weather conditions, such as operating on rain-flooded runways, without compromising safety or performance. This achievement moves the SJ-100 closer to full certification and, ultimately, to serial production, underpinning a broader strategy to revitalize Russia’s civil aviation manufacturing industry and ensure its long-term self-sufficiency.
To certify an aircraft for commercial use, Manufacturers must prove its systems can endure a wide range of environmental challenges. The water ingestion test is one of the most demanding of these trials. It is designed to simulate real-world scenarios like landing or taking off during a torrential downpour, where large amounts of water can be kicked up from the runway surface and drawn into the engines. Failure in such a scenario could lead to engine flameout or catastrophic damage, making this test a non-negotiable hurdle in the certification process.
The tests for the SJ-100 were conducted at the Gromov Flight Research Institute in Zhukovsky, near Moscow. A specially constructed basin, described as a “water pool” measuring over 70 meters long and 12 meters wide, was built on the runway. The test aircraft, numbered 97023, performed a series of high-speed runs through this pool to mimic the conditions of takeoff and landing in heavy rain. During these runs, the engines, as well as the aircraft’s auxiliary power unit (APU), were subjected to massive water spray. The trials also included the operation of the PD-8’s thrust reversers, which are used to help slow the aircraft upon landing and can exacerbate water ingestion.
The outcome was a resounding success. Officials confirmed that the ingestion of water did not negatively impact the operation of the PD-8 engines or the APU. According to Vadim Shirokih, the Chief of the Yakovlev Regional Aircraft Flight-Test Complex, the tests verified that water “does not interfere with the operation of the aircraft’s engines or auxiliary power unit.” This result provides critical data affirming the engine’s robust design and its readiness for all-weather operations, a key requirement for any commercial airliner.
“The PD-8 engines, developed by United Engine Corporation using advanced domestic technologies, showed stable and reliable performance during the ‘water pool’ tests, guaranteeing passenger safety under all weather conditions.” – Fedor Mironov, Deputy Director for Sales at UEC.
The development of the PD-8 engine is the centerpiece of the SJ-100’s import substitution program. The original Superjet 100 was powered by SaM146 engines, a joint venture between a French and a Russian company. Sanctions made continued reliance on this partnership untenable, forcing an accelerated push for a fully domestic powerplant. The PD-8 was developed by leveraging technologies from the larger PD-14 engine, which powers Russia’s MC-21 medium-range airliner. This approach allowed engineers to fast-track development while incorporating proven, modern design principles.
The engine is a testament to Russia’s advancements in materials science and aerospace engineering. It incorporates new Russian-developed alloys and features a fully domestic electronic control system, breaking free from dependence on foreign-supplied components. Its technical specifications are competitive, with a bypass ratio of 4.4 and a specific fuel consumption in cruise mode below 0.62 kg/kgf·h, indicating a focus on efficiency. The versatility of the PD-8 design is also notable, as engineers are adapting it for use on the Beriev Be-200 amphibious aircraft, a platform that operates in even more demanding water-based environments.
The successful water test is just one of several milestones the SJ-100 has recently achieved. The aircraft has undergone stability and controllability checks at high speeds, evaluations of its integrated control system in extreme flight attitudes, and testing of the PD-8’s thrust reversers. This comprehensive testing program is paving the way for the aircraft’s final Certification, which is anticipated by the end of 2025, with mass production slated to begin in 2026. The successful water ingestion tests of the SJ-100’s PD-8 engines are more than just a technical achievement, they represent a pivotal moment in Russia’s quest for a sovereign and competitive civil aviation industry. By proving the reliability of its homegrown engine technology under harsh conditions, Russia has cleared a major obstacle on the path to deploying a fully domestic regional jet. This progress is a direct result of a focused national strategy to overcome the limitations imposed by international sanctions and rebuild its industrial capabilities from the ground up.
Looking ahead, the SJ-100 program is a cornerstone of a larger plan to manufacture over 600 domestic aircraft by 2030, replacing an aging fleet of Western-built planes. The establishment of 15 dedicated service centers is also planned to support this new fleet, creating a comprehensive ecosystem for maintenance and spare parts. The journey is far from over, but the steady progress of the SJ-100, marked by milestones like this successful test, signals a clear trajectory toward reviving large-scale domestic aircraft manufacturing and securing Russia’s place in the global aerospace landscape on its own terms.

United Airlines announces the United Relax Row lie-flat economy seating and a fleet expansion with 250+ new aircraft by 2028.
This article is based on an official press release from United Airlines.
United Airlines announced a major strategic update on March 24, 2026, focusing on premium seating innovations and a massive fleet expansion. According to the official press release, the airline is introducing the “United Relax Row,” a lie-flat economy seating option, alongside a commitment to take delivery of more than 250 new aircraft by April 2028.
We note that this dual announcement represents one of the most aggressive pushes by a North American carrier to capture the growing premium leisure market. By bridging the gap between standard economy and business class, and simultaneously upgrading its domestic transcontinental and international widebody fleets, United aims to solidify its position as the premium airline of choice for both domestic and global travelers.
The centerpiece of the announcement for economy travelers is the United Relax Row. Designed specifically for families, couples, and solo flyers, this product transforms a standard row of three United Economy seats into a lie-flat space. The press release details that individually adjustable leg rests fold up at a 90-degree angle to create a flat, mattress-like surface.
Passengers booking this option will receive a custom-fitted mattress pad, a specially sized plush blanket, two additional pillows, and a Children’s Travel Kit featuring a plush toy. United states that the Relax Row will be located between the standard United Economy and United Premium Plus cabins, with up to 12 sections available per aircraft.
The airline expects to launch the Relax Row in 2027, with plans to install it on more than 200 Boeing 787 and 777 widebody aircraft by 2030. Notably, United holds North American exclusivity on this design, making it the first airline on the continent to offer such a product.
Andrew Nocella, Executive Vice President and Chief Commercial Officer at United Airlines, emphasized the customer-centric approach in the company’s press release:
“Customers traveling in United Economy on long-haul flights deserve an option for more space and comfort, and this is one way we can deliver that for them. United is the only North American airline offering a product like the United Relax Row and is one of the many reasons why we’re continuing to win brand loyal customers.”
Beyond economy innovations, United’s press release outlines a record-setting fleet growth plan, adding more than 250 new aircraft by April 2028. This expansion introduces several new sub-fleets and elevated cabin experiences designed to modernize the airline’s offerings. To compete in the lucrative domestic transcontinental market, United is launching the “Coastliner” subfleet. Comprising 100 new airplanes to replace 40 older, less efficient Boeing 757s, these aircraft will feature a special livery and fly exclusively between West Coast hubs in San Francisco and Los Angeles to Newark and New York. The Coastliner will bring the United Polaris cabin experience, including Polaris lounge access, to domestic travelers. Additionally, Airbus A321XLR aircraft will enter service later in 2026, featuring 32 premium seats, an increase of 16 seats compared to the 757s they replace.
Internationally, United will debut a Boeing 787-9 with an “Elevated” interior on April 22, 2026, flying from San Francisco to Singapore. This aircraft introduces the United Polaris Studio, lie-flat, all-aisle-access suites that are 25 percent larger than standard Polaris seats. Features include privacy doors, companion ottomans, 27-inch 4K OLED seatback screens, wireless charging, and exclusive meal services with caviar and wine pairings. The airline plans to operate 33 of these upgraded aircraft by 2028. Furthermore, United reaffirmed its commitment to install free Starlink Wi-Fi for MileagePlus members on all dual-cabin planes by the end of 2027.
We view United’s latest announcements as a direct response to permanent shifts in post-pandemic consumer behavior. The “premium leisure” boom has demonstrated that travelers are increasingly willing to pay for enhanced comfort. The United Relax Row effectively captures revenue from passengers who desire a lie-flat experience but are priced out of the traditional Polaris business class cabin.
Furthermore, the introduction of the Coastliner subfleet signals a fierce escalation in the domestic transcontinental battle against competitors like Delta Air Lines and JetBlue’s Mint product. Coupled with the airline’s recent expansion into unique international markets such as Nuuk, Greenland, and Dakar, Senegal, these cabin upgrades are strategically timed to make ultra-long-haul routes more appealing and comfortable for a broader demographic, establishing a strong competitive moat.

United Airlines to Add 250 Planes with Premium Travel Focus by 2028
United Airlines plans to expand its fleet by 250+ planes by 2028, introducing new premium aircraft and enhanced passenger amenities.
This article is based on an official press release from United Airlines via PR Newswire.
United Airlines has unveiled a sweeping fleet expansion plan, announcing it expects to take delivery of more than 250 new aircraft by April 2028. According to the company’s press release, this represents the highest number of aircraft deliveries by any airline in a two-year period. The expansion heavily emphasizes “premiumization,” introducing bespoke aircraft subfleets and high-end amenities designed to attract lucrative business and luxury travelers.
The announcement, made on March 24, 2026, builds upon the carrier’s ongoing “United Next” strategy, which originally launched in 2021. Since the inception of that strategy, United reports it has added 326 Boeing and Airbus aircraft to its fleet, retrofitted 70 percent of its narrow-body planes, and increased its premium seat count per North American departure by 40 percent.
By introducing four distinct new aircraft configurations, including a custom transcontinental narrowbody and an ultra-premium long-haul widebody, United is signaling a definitive shift away from competing solely on basic ticket prices. Instead, the airline is focusing on decommoditizing the passenger experience through enhanced privacy, upgraded dining, and high-speed connectivity.
To cater to distinct market segments, United’s press release details the introduction of four specialized aircraft configurations, ranging from regional jets to international widebodies.
For domestic transcontinental routes, United is introducing the Airbus A321neo “Coastliner.” The airline has ordered 50 of these aircraft, with 40 expected to enter service by early 2028. Designed specifically for flights connecting Newark (EWR) to Los Angeles (LAX) and San Francisco (SFO), the Coastliner will feature 161 seats, including 20 Polaris lie-flat suites and 12 Premium Plus seats. Notably, the company states this is the first time it will offer a dedicated Premium Plus cabin on a narrowbody domestic flight. To further elevate the economy experience, United removed three standard seats to install a walk-up snack bar in the rear cabin. Domestic Polaris passengers on these routes will also receive access to United Polaris lounges.
For short-to-medium-haul international routes, United is bringing in the Airbus A321XLR to replace its aging Boeing 757 fleet. With 50 ordered and more than half expected by 2028, the 150-seat aircraft will feature 32 premium seats, 16 more than the 757s they replace. Like the Coastliner, the A321XLR will include an economy snack bar, but it will also feature functional privacy doors for its Polaris suites.
On the long-haul international front, United announced the Boeing 787-9 with an “Elevated” interior. The airline has ordered 47 of these widebodies, expecting 33 to fly with the new interior by 2028. The aircraft boasts 99 premium seats and debuts the “Polaris Studio”, eight exclusive front-row suites that are 25 percent larger than standard Polaris seats. According to the release, these studios feature privacy doors, a companion ottoman, a 27-inch 4K OLED screen, and an exclusive Ossetra caviar service. The inaugural flight for this aircraft is scheduled for April 22, 2026, from San Francisco to Singapore. At the regional level, United is partnering with SkyWest to operate the CRJ450. This reimagined 41-seat regional jet replaces traditional first-class overhead bins with a dedicated luggage closet, a design choice the airline says is intended to evoke a private jet environment for passengers connecting from smaller cities to hubs in Chicago and Denver.
Alongside the new hardware, United is overhauling its in-flight amenities and technological offerings. The airline confirmed it is rolling out high-speed, gate-to-gate Starlink satellite internet, which will be free for all MileagePlus members. United expects to install Starlink on all dual-cabin aircraft by the end of 2027.
In a unique culinary move, United announced a partnership with the Emmy-winning Netflix series Chef’s Table. Starting August 1, 2026, eleven renowned chefs will curate regionally-inspired meals for Polaris international flights. Additional premium cabin upgrades include Saks Fifth Avenue bedding, Perricone MD skincare kits, Meridian noise-canceling headphones, and 4K OLED screens with Bluetooth connectivity at every seat.
“This is another step in a decade-long journey that we’ve been on at United to de-commoditize the industry… to really try to win customer loyalty, make an airline that customers love to fly.” “Our collaboration with Chef’s Table shows how we’re leveraging our unique position as the world’s largest airline to deliver restaurant-quality moments in the sky.” We observe that United’s aggressive push into the premium market comes at a critical macroeconomic juncture for the aviation industry. Recent industry reports and executive warnings highlight that rising jet fuel prices, exacerbated by ongoing Middle East conflicts, pose a significant threat to airline profitability. CEO Scott Kirby recently noted that if oil remains above $100 a barrel, it could add up to $11 billion to United’s annual fuel bill.
By investing heavily in high-margin premium seating and exclusive amenities, United appears to be building a financial hedge against these volatile operational costs. Recent quarterly data indicates United’s premium revenue has increased by 9 to 11 percent, significantly outpacing basic economy growth. Furthermore, the introduction of the “Coastliner” effectively blurs the traditional lines between domestic and international travel standards. By offering widebody-grade luxury, such as lie-flat seats, premium economy, and lounge access, on single-aisle transcontinental routes, United is forcing competitors to rethink their own domestic premium products.
