Mahle prototype single-cylinder natural gas engine

The Sikorsky-Boeing SB-1 Defiant (stylized as “SB>1 DEFIANT”) compound helicopter flew for the first time at Sikorsky’s West Palm Beach, Florida facility. Unlike current rotorcraft, the SB-1 Defiant’s propulsion system includes a rear-mounted pusher propulsor in addition to two coaxial main rotors. This unique setup allows the Defiant to reach speeds and a service range far beyond that of modern helicopters.

The latest version of Honeywell Aerospace’s seven-stage axial compressor T55 turboshaft engine is nearing the final phase of development. Designed with next-generation technology to increase reliability, power, and fuel economy, the Honeywell T55-L-71X will find a home onboard the medium-lift Sikorsky-Boeing SB-1 Defiant compound helicopter demonstrator.

Stratolaunch Systems Corp., founded by Paul G. Allen, in Seattle, Washington, has completed the first flight of the Stratolaunch, the world’s largest all-composite aircraft, with a dual-fuselage design and wingspan greater than the length of an American football field. The Stratolaunch aircraft took flight on April 13 at 0658 PDT from the Mojave Air & Space Port in Mojave, California; achieved a maximum speed of 189 miles per hour; and flew for 2.5 hours over the Mojave Desert at altitudes up to 17,000 feet. 

The National Center for Advanced Materials Performance (NCAMP) of Wichita State University (WSU) is partnering with SAE International to develop globally harmonized aerospace material and process specifications for advanced composites and non-metal additive manufacturing (AM) materials in the aerospace and air transport industries.

Standards development teams at SAE International in Warrendale, Pa., have issued 11 new technical documents and revised or reaffirmed another 54 technical reports focused on mobility engineering across the aerospace, automotive, and commercial transportation communities. The new documents, issued throughout June 2018, cover a variety of technical subject areas, including: diagnostic link connector security, mitigation strategies against illumination effects, data dictionary for quantities used in cyber physical exams, requirements for production of metal powder feedstock for use in additive manufacturing of aerospace parts, and laser powder bed fusion process.

General Atomics Aeronautical Systems, Inc. is using an integrated fuel tank structure to maximize fuel offload for the company’s proposed MQ-25 design for the U.S. Navy. The Navy plans to deploy one of three potential MQ-25 designs by the early- to mid-2020s.

The 3D printing materials market will experience high double-digit growth in the aerospace industry through 2024, as manufacturers of aircraft and spacecraft vehicles and components increasingly adopt and reap the benefits of additive manufacturing, market analysts at Frost & Sullivan in Mountain View, California, predict.

Jun 13, 2018 - The Aerospace Material Specification committee on Additive Manufacturing (AMS-AM) at SAE International in Warrendale, Pennsylvania, has released its first suite of Aerospace Material Specifications (AMS) additive manufacturing materials and process specifications. The new aerospace technical standards, now available from SAE, support the certification of critical aircraft and spacecraft parts, providing both a framework to protect the integrity of material property data and traceability within the aerospace supply chain.

The Auto-Tracking Antenna System, a new portable, ground-to-air antenna from Persistent Systems LLC in New York, incorporates aircraft into the Wave Relay mobile ad hoc network (MANET) to boost connectivity, communications, and distribution of critical sensor data, including full-motion video, on the networked battlefield. The precisely aimed tracking system works with the MPU5 radio and Wave Relay MANET to optimize connectivity and reliable communications to enable manned and unmanned aircraft to communicate further than ever before, officials say.

AeroVironment revealed its critical role in collaborating with NASA JPL to build the “Mars Helicopter” for NASA’s Mars Exploration Program. Program officials plan to have the Mars Helicopter flying on Mars in less than three years.

Under the OFFSET program, BBN Technologies (a subsidiary of Raytheon) is developing direct and control solutions for swarms of small, autonomous air, and ground vehicles.

Connected aircraft means more than just in-flight movies, free texting, and Facebook posting with friends while in flight. In fact, the connected aircraft revolutionizes airline operations, dramatically improving fleet management, flight safety, passenger experience, maintenance, flight operations, aircraft turnaround time, and costs. For aircraft operators, connectivity presents a new set of operational benefits that were previously unavailable.

Even at the early stages of this new era of urban air mobility, there is already a scramble amongst well-known aerospace giants, as well as start-ups, to develop and evaluate the civil VTOL market. And this all starts with air-taxi concepts.

Aerospace systems, subsystems, and components must continue to operate as intended when exposed to fire, rather than going up in flames and ceasing to work altogether. Fire and flammability testing is an all-important prerequisite to airworthiness, and the focus of a new technical standards committee that SAE International in Warrendale, Pennsylvania, is forming in response to a request from Federal Aviation Administration (FAA) officials in Washington.

Nano Dimension Ltd., an additive electronics provider based in Ness Ziona, Israel, has developed the world’s first side-mounting technology for printed circuit boards (PCBs) produced through additive manufacturing (AM) or “3D-printing.” The side mounted designs allow for more functionality on circuit boards, which will impact Internet of Things (IoT) and Industry 4.0 applications where customized designs and shapes are a growing demand.

In contrast to the stiff, rigid wings found on most commercial aircraft, flexible wing technology is considered essential to next generation, fuel efficient aircraft. However, flexible wings are susceptible to “flutter,” or highly destructive aeroelastic instability. To better understand and mitigate flutter, engineers at NASA’s Armstrong Flight Research Center (AFRC) equipped the X-56 with fiber optic sensing (FOS) technology.

SAE International is partnering with Ford, General Motors (GM), and Toyota to form the Automated Vehicle Safety Consortium (AVSC), which will work to help safely advance the testing, precompetitive development, and deployment of SAE Level 4 and 5 automated vehicles. The AVSC will provide a safety framework around which autonomous technology can responsibly evolve in advance of broad deployment, ultimately helping to inform and accelerate the development of industry standards for autonomous vehicles (AVs) and harmonize with efforts of other consortia and standards bodies. 

Goodfellow’s process involves breaking methane gas – a very potent greenhouse gas – into hydrogen and elemental carbon atoms in a plasma reactor. The carbon atoms recombine into graphene sheets in the hydrogen atmosphere.

Chicago-based Boeing recently completed a “demo flight” of a 737 MAX 7 narrow-body airliner equipped with updated Maneuvering Characteristics Augmentation System (MCAS) software.
