Safran contributes to 2020 Boeing ecoDemonstrator with new landing gear noise reduction technology
Safran Landing Systems' selection underlines its high level of expertise in landing gear integration and noise reduction technology for aircraft across all market segments.
Safran Landing Systems, which supplies the landing gear for the 787 Dreamliner, will outfit the 2020 ecoDemonstrator with landing gear noise reduction devices. The objective is to attenuate the landing gear acoustic contribution by more than 20%. Modern aircraft engines have reduced their noise signature to the point that the landing gear is now one of the largest contributing factors to noise on approach and landing. On average, it can account for 30% to 40% of the external approach noise on modern long-haul aircraft.
For the 2020 program, which will begin testing in August, Boeing and Etihad Airways will use for the first time a Boeing 787-10. Sound measurements will be conducted on the airplane and the ground to validate community noise prediction processes and the sound reduction potential of a landing gear modified for quieter operations. Testing on the ecoDemonstrator will validate the efficacy of potential design solutions for the next generation of landing gear.
"This year marks our seventh ecoDemonstrator program, and continues our history of innovation and technology acceleration using flight demonstrators while collaborating with industry partners like Safran," said Kourosh Hadi, Boeing Director of Airplane Product Development including the ecoDemonstrator program. "These shared learnings benefit all as we push to make travel more sustainable, enjoyable and safe for passengers. Safran's noise reduction testing can make strides in reducing noise for our communities, and we value their contributions to the program."
"We are very proud to partner with Boeing and support environmental efforts through our involvement in the ecoDemonstrator program," said Jean-Paul Alary, Chief Executive Officer of Safran Landing Systems. "This program is fully aligned with Safran's forward-looking strategy, ensuring that the future generation of landing, braking and taxiing systems will be lighter, quieter, more cost-efficient and reliable."
Lockheed Martin and University of Southern California Build Smart CubeSats, La Jument
Lockheed Martin (NYSE: LMT) is building mission payloads for a Space Engineering Research Center at University of Southern California (USC) Information Sciences Institute small satellite program called La Jument, which enhance Artificial Intelligence (AI) and Machine Learning (ML) space technologies.
For the program, four La Jument nanosatellites -- the first launching later this year -- will use Lockheed Martin’s SmartSat™ software-defined satellite architecture on both their payload and bus. SmartSat lets satellite operators quickly change missions while in orbit with the simplicity of starting, stopping or uploading new applications.
The system is powered by the NVIDIA® Jetson™ platform built on the CUDA-X™ capable software stack and supported by the NVIDIA JetPack™ software development kit (SDK), delivering powerful AI at the edge computing capabilities to unlock advanced image and digital signal processing.
SmartSat™ provides on-board cyber threat detection, while the software-defined payload houses advanced optical and infrared cameras utilized by Lockheed Martin’s Advanced Technology Center (ATC) to further mature and space qualify Artificial Intelligence (AI) and Machine Learning (ML) technologies. The La Jument payloads are the latest of more than 300 payloads Lockheed Martin has built for customers.
“La Jument and SmartSat are pushing new boundaries of what is possible in space when you adopt an open software architecture that lets you change missions on the fly,” said Adam Johnson, Director of SmartSat™ and La Jument at Lockheed Martin Space. “We are excited to release a SmartSat software development kit (SDK) to encourage developers to write their own third-party mission apps and offer an orbital test-bed.”
Powering Artificial Intelligence at the Edge
La Jument satellites will enable AI/ML algorithms in orbit because of advanced multi-core processing and on-board graphics processing units (GPU). One app being tested in orbit will be SuperRes, an algorithm developed by Lockheed Martin that can automatically enhance the quality of an image, like some smartphone camera apps. SuperRes enables exploitation and detection of imagery produced by lower-cost, lower-quality image sensors.
“We were able to design, build and integrate the first payload for La Jument in five months,” said Sonia Phares, Vice President of Engineering and Technology at Lockheed Martin Space. “Satellites like this demonstrate our approach to rapid development and innovation that lets us solve our customers' toughest challenges faster than ever.”
Bringing Four Satellites Together
The first of the four La Jument nanosatellites is a student-designed and built 1.5U CubeSat that will be launched with a SmartSat payload to test the complete system from ground to space, including ground station communications links and commanding SmartSat infrastructure while in-orbit. The second is a 3U nanosat, the size of three small milk cartons stacked on top of each other, with optical payloads connected to SmartSat that will allow AI/ML in-orbit testing. Finally, two 6U CubeSats are being designed jointly with USC that will be launched mid-2022. The pair will launch together and incorporate future research from USC and Lockheed Martin, including new SmartSat apps, sensors and bus technologies.
Lockheed Martin has a long history of creating small satellites, having launched more than 150. More recent nanosat projects include Pony Express 1, Linus, NASA’s Lun-IR, Janus and Grail. Additionally, Lockheed Martin will be the prime integrator for DARPA’s Blackjack small sat constellation.

Preliminary results of MC-21-300 aircraft tests on engines protection against water penetration are summed up
Irkut Corporation summarized the preliminary results of MC-21-300 aircraft ground testing, which confirmed the possibility of operating the aircraft in presence of water on runway.
During the period from 16 to 22 July 2020, the MC-21-300 aircraft performed 29 runs and 3 taxing on water at speeds from 10 to 150 knots (1 knots = 1.852 km/hour) at various configurations of mechanization and power plant modes, including the use of engines thrust reversal.
The tests were carried out on the "Ulyanovsk-Vostochny" airfield, where the "pool" of more than 70 m long and more than 20 m wide was mounted. Parameters of the "pool" provided a normalized water depth in accordance with Russian and international requirements, which are established for these types of tests.
In the process of testing the possibility of safe movement on a wet runway in a wide range of speeds without any failure of marching and auxiliary power plants, as well as other systems and equipment of the aircraft were confirmed.
In addition, the tests found that the MC-21-300 aircraft is steadily moving and retains control on the runway covered with water.
The course of testing was recorded by a complex of onboard measurements of the aircraft and a system of video cameras installed on the ground and on the aircraft.
The tests were conducted as part of the MC-21-300 aircraft certification program with the participation of representatives of authorized certification centers.
