  America’s F-22 stealth fighter may be limited in Asia-Pacific conditions, China’s J-20 designer says

  Aircraft has been sent to the region but was designed for combat in Europe, which could affect its capabilities, according to Yang Wei China's answer to the Raptor has yet to be put to the test in a real combat situation, military expert notes Minnie Chan Published: 12:00am, 30 Jul, 2020 America's F-22 Raptor stealth fighter was designed for combat in Europe but is now being used in the Asia-Pacific, according to a top Chinese aircraft designer, who says the different conditions will limit its capabilities there. Yang Wei, general designer of China's first stealth fighter the J-20, said the twin-engine F-22s could face the same challenges in the region as the F-4 fighter-bombers the Pentagon sent to the Vietnam war between 1965 and 1973. “The complex environment and political constraints in Vietnam caused the F-4 to almost fail to show its high-speed performance and over-the-horizon combat capabilities,” Yang wrote in a paper published in Chinese aeronautics journal Acta Aeronautica et Astronautica Sinica last month. He said the F-22, a tactical fighter inspired by the Cold War between the United States and the former Soviet Union, was designed for battle in Europe and could face similar problems now that it had been deployed in the Asia-Pacific. Yang did not draw any comparisons between America's F-22 and China's J-20 both fifth-generation, twin-engine heavy fighter jets and of a similar size. But military experts said his remarks indicated that the J-20 Weilong, or Powerful Dragon, was clearly seen as China's answer to the F-22. Comparing the two, Song Zhongping, a military commentator in Hong Kong, said the J-20's biggest advantage was that it was developed later, meaning its designers could learn from the F-22 – including how to fix shortcomings, and what type of new technologies could be used to optimise the aircraft. “The F-22 was originally designed for combat with the former Soviet Union, or today's Russia, in Europe, but now the Raptor's main opponent is the [People's Liberation Army] in the Asia-Pacific,” Song said. “China's J-20 was inspired by the F-22's deployment. The Chinese aircraft designers used the Raptor as a rival and the F-35 [stealth multi-role fighter] as a tactical opponent to help them to come up with a more practical and capable fighter jet.” Both the F-22 and the J-20 have a ceiling of 20km (12.4 miles) and a maximum speed of over Mach 2 (2,470km per hour, or 1,535mph) – faster than the speed of sound. The F-22 has a comparatively shorter range – with a combat radius of 800km (497 miles), while the J-20's large internal fuel tank can sustain a longer combat radius of 1,100km (684 miles). But Beijing-based military expert Zhou Chenming noted that the J-20, which entered service in 2017, had yet to be put to the test in a real combat situation. Andrei Chang, founder of influential military magazine Kanwa Asian Defence, said that in contrast, the F-22's combat capabilities had been seen, most recently last year when the stealth fighters were sent to Qatar as tensions rose with Iran. “The operation of the F-22 has been perfected since it joined the US military in 2005. The Raptor has taken part in countless actual combat situations around the globe, including in the Middle East, Singapore and Okinawa in the Pacific,” Chang said. A military source close to the PLA believed the J-20 could counter the F-22 in a one-on-one combat situation, but said far fewer of the fighter jets had been made compared to America's Raptors. “At the moment China has about 60 J-20s – just one-third of the total number of F-22s,” said the source, who requested anonymity due to the sensitivity of the matter. “Now the US has deployed hundreds of F-35s to the region, so it's an even bigger threat to China,” he added. With F-22s being deployed to the Asia-Pacific region – and as relations worsen with Washington, including over the disputed South China Sea – Beijing has stepped up development of its new stealth fighter. Mass production of the J-20B began earlier this month. https://www.scmp.com/news/china/military/article/3095219/americas-f-22-stealth-fighter-may-be-limited-asia-pacific

  Singapore Airshow 2020: ST Engineering unveils Veloce family of fixed wing VTOL UAVs

  Singapore defence prime ST Engineering has unveiled the Veloce family of hybrid fixed-wing/vertical take-off and landing (VTOL) unmanned aerial vehicles (UAVs) at the 2020 Singapore Airshow, which is being held at the Changi Exhibition Centre from 11-16 February. The company is showcasing two market-ready Veloce variants - the Veloce 15 (V15) and Veloce 60 (V60) - at the event, with both air vehicles centred on a common airframe design comprising a main fuselage pod that supports the type's payload, avionics, shoulder-mounted wings, and a rear-mounted piston engine that drives a two-bladed pusher propeller. The airframe also features four vertical-lift electric motors housed in booms attached to the underside of the wings, which in turn supports an inverted V-shaped tail assembly. Like other fixed-wing VTOL UAVs produced by manufacturers elsewhere in the world, both the V15 and V60 can be deployed without a runway or a dedicated launch and recovery system (LARS) due to their ability to take-off and land vertically using their electric motors, before transitioning to conventional flight when the appropriate altitudes have been reached. The V15 will feature a 3.7 m wingspan and a maximum take-off weight (MTOW) of between 16-17 kg as well as speed and endurance ranges of between 30-40 kt and 2-3 hours depending on its configuration, although it will typically carry a nose-mounted electro-optical/infrared (EO/IR) turret. In contrast, the larger and more capable V60 will feature a 5 m wingspan and a MTOW of between 50-70 kg, while flying at payload-dependent speeds of between 50-70 kt and staying aloft for 12-14 hours. It will also carry a nose-mounted EO/IR turret with provision for an optional laser rangefinder. https://www.janes.com/article/94301/singapore-airshow-2020-st-engineering-unveils-veloce-family-of-fixed-wing-vtol-uavs?from_rss=1

  Major players pitch solutions for Navy’s next training helicopter

  By: Jen Judson NATIONAL HARBOR, Md. — Several major players in the helicopter industry pitched possible solutions at the Navy League's Sea-Air-Space conference for the Navy's next initial-entry, rotary-wing training helicopter as the service signals stronger intentions to replace its aging TH-57 Sea Ranger fleet. The Navy has announced during recent congressional hearings that it plans to buy a new training helicopter in fiscal 2020. For years, the service has put out requests for information asking industry for training helicopter options with the latest coming out in October 2017. That RFI left some requirements open-ended such as whether the aircraft should have one or two engines, but has asked for the helicopter to be Instrument Flight Rules (IFR) certified, an obvious requirement when flying over sea or in reduced visibility environments. It's also assumed the Navy wants a commercial off-the-shelf aircraft. The TH-57 is more than reaching the end of its life, having first been fielded to the Navy's training fleet in the 1970s. So three companies — Airbus, Bell and Leonardo — all brought examples of possible training helicopters to the Navy's biggest trade show. Airbus H135 Airbus is keeping all of its options on the table for a Navy trainer because the service has yet to define all of its requirements, according to John Roth, senior director of business development for Airbus Helicopters Inc. “We have a broad product range that goes from light, single-engine into light, twin-engine to medium and heavy twin-engine platforms,” Roth told Defense News at Sea-Air-Space. “Our approach is we will evaluate those requirements and offer based on those requirements. However, given the nature of training and how the complexity of training has evolved over time, we do have recommendations for the Navy as it relates to having the best possible solution to accomplish all of their missions.” And one recommendation is the H135 light, twin-engine helicopter Airbus had on display at the show. “We believe this is certainly a very capable potential solution that meets all the Navy requirements as a commercial off-the-shelf product,” Roth said. The H135 is similar to the EC-145 helicopter that the Army now uses for its trainer, replacing its TH-67 Creek helicopters with LUH-72A Lakota light utility helicopters already in the service's inventory beginning in 2014. The Army's decision to retire the TH-67s and replace them with Lakotas was met with much debate as to whether it made sense to teach helicopter pilots basic skills in a more complex digital glass cockpit helicopter with twin engines. And the decision was even met with a lawsuit. Leonardo — then known as AgustaWestland — sued the Army over its decision not to compete for a new trainer but to instead sole-source a helicopter already fielded by the service. Leonardo initially won the lawsuit but the decision was overturned in the appellate court. The Army is still filling out its Lakota training fleet, but, Roth said, “from a qualitative perspective, we've got some very positive feedback that talks to capability of the aviators when they complete the training and having them more prepared for the advanced aircraft once they arrive at their advanced training stations.” The fact that both the Lakota and the H135 have advanced digital glass cockpits, four-axis autopilot and twin-engine capability with Full Authority Digital Engine (FADEC) controls “all prepared them for the type of vehicle that they are going to get in when they get into their advanced training,” Roth said. The Army has taken tasks normally taught in the more expensive advanced aircraft and brought those down to basic training, he added. “There has been a lot of advantages realized from that decision that we think the Navy will be able to take advantage of as well,” Roth said. The H135s, if purchased by the Navy, would be built at its Columbus, Mississippi, production line where commercial EC135s and Lakotas are built. The helicopter pitched to the Navy is also used by approximately a dozen countries with nearly 130 aircraft serving as a primary trainer worldwide, Roth said. Bell 407 GXi Bell would be the incumbent in a competition for a new Navy trainer, being the current manufacturer of the TH-57. The company plans to offer up its 407 GXi, according to Steve Mathias, Bell's vice president for Global Military Business Development. Bell has already built and sold 1,500 407s worldwide which have flown over 4.75 million hours, he said, so the helicopter is “very reliable, sustainable, maintainable glass cockpit, just a great overall aircraft,” Mathias said. And from a programmatic perspective, he said, choosing Bell's trainer offers “a lot less risk because it's very similar to the TH-57 that the Navy currently has, so a transition from a Bell product to a Bell product would be a lower risk, I would think, to the customer.” Bell also provides many of the helicopters the Navy and Marine Corps fly today such as the UH-1Y Venom, the AH-1Z Viper and the V-22 Osprey tiltrotor and therefore has a high level of experience working with the services on a day-to-day basis “so we very closely understand what the Navy requirements are,” Mathias argued. The company is hoping the Navy chooses to go with a single-engine aircraft because it would “be less costly to operate” and less complex to train, according to Mathias. He added that he believes the choice would offer the best value to the service. Leonardo TH-119 Italian company Leonardo is making a play for the trainer with plans to submit its TH-119, which puts them, like Bell, into the single-engine camp, according to Andrew Gappy, who is in charge of the company's government sales and programs. The helicopter is a variant of the AW119Kx, a single-engine, full-spectrum training aircraft and can be used for training from the basics like learning how to hover above the ground all the way to advanced tactics. And while Leonardo is a foreign company, all of the 119s worldwide are manufactured in Philadelphia, Pennsylvania. The 119 is also IFR certified to meet that Navy requirement. The helicopter is known for its significant power, which means the aircraft's training mission sets can grow and change over time without affecting its performance, Gappy said. It's important for the Navy to buy a new trainer now because, Gappy said, he trained on the TH-57 “a long time ago.” The aircraft averages roughly 70,000 flight hours a year and will become more and more costly to operate as it continues to age. “When I went through, the TH-57 had a lot in common with combat aircraft, how the aircraft flew and instrumentation training was really relevant,” he said. “It's so disparate now with glass cockpits and all of them are multi-bladed rotor systems that fly differently than the twin rotor system, so it's really resetting the baseline,” which allows the service to incorporate more advanced training into the basic courses that has migrated away from that training due to the loss in power margin, Gappy said. https://www.defensenews.com/digital-show-dailies/navy-league/2018/04/11/major-players-pitch-solutions-for-navys-next-training-helicopter/
