Chrysler's new Hellcat V8 gets 707-hp SAE rating
2014-05-21
The actual J1349 rating is more than 100 hp more than Chrysler engineers teased in late May. The automaker's first production supercharged V8 uses a Lysholm-type twin-screw supercharger supplied by IHI. The engine's high-output spec required extensive upgrading of engine reciprocating components to handle the extra loads.

Bosch developing new water-injection system for production engines
2015-06-02
The WI system is in pilot development with a Bosch customer. Test results to date show a reduction of fuel consumption at high loads and low rpm (up to 4% improvement on the NEDC cycle); reduction or avoidance of fuel enrichment and lower exhaust-gas temperatures at high loads and high rpm, and improved torque.

GKN Aerospace to develop first additive-manufactured rocket engine turbines in Europe for Prometheus project
2018-09-05
GKN Aerospace in Trollhättan, Sweden, are developing and manufacturing the first additive-manufactured, or 3D-printed, rocket engine turbines in Europe, officials say. The tier 1 aerospace supplier is harnessing cutting-edge additive manufacturing (AM) technology to produce two full-scale turbines for the Prometheus reusable rocket engine demonstrator on liquid oxygen and methane propellants, while reducing the number of parts from more than 100 to 2 and cutting costs by 90 percent.

Automation streamlines accreditation to speed aerospace and defense technology deployment
2018-12-07
Automated software tools are eliminating weeks, if not months, from the Risk Management Framework (RMF) accreditation process by virtually eliminating the time of the initial hardening while also providing the required documentation. By doing so, technology integrators can significantly reduce the time to build, test, and deploy new technologies in Security Technical Implementation Guide (STIG)-compliant environments.

Bell Nexus full-scale air taxi design debuts, taps novel VTOL, hybrid propulsion, energy storage, and avionics technologies
2019-01-09
Mobility engineers and executives at Bell Helicopter, a Textron Inc. (NYSE:TXT) company, in Fort Worth, Texas, are developing new concepts of mobility to make moving people and products more efficient and effective – and launching urban air mobility (UAM) innovations, including the Bell Nexus air taxi design, at the Consumer Electronics Show (CES) in Las Vegas this week. They envision and are helping to enable a fleet of on-demand, quiet vertical-takeoff-and-landing (VTOL) aircraft capable of safely whisking passengers over traffic and across urban landscapes by the mid-2020s.

FAA, SAE International focus on engine fire protection system standards for aerospace
2018-06-18
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.
