SAE International has published a new recommended practice for assessing the amount of nonvolatile particulate matter (nvPM) that exits aircraft engine exhaust nozzles – ARP6481: Procedure for the Calculation of Non-Volatile Particulate Matter Sampling and Measurement System Losses and System Loss Correction Factors
Thermal imaging data obtained from a FLIR high-performance camera shows that the expected turbine output temperature is approximately 285°C when the helicopter is in forward flight. However, during hover operations a steady state temperature of about 343°C will be reached.
While engine manufacturers fill orders from large operators for numerous new commercial engine types, maintenance costs of older, in-service engines will also continue to rise. Analysts currently estimate that engine maintenance and repair will contribute to nearly 30% of the predicted $25 billion 2018 maintenance, repair, and overhaul (MRO) market—with most of the growth occurring in the Asia-Pacific region.
Sikorsky, a Lockheed Martin company (NYSE:LMT), in Stratford, Connecticut, and Boeing Defense, Space & Security (NYSE:BA) in Berkeley, Missouri, are introducing the SB>1 DEFIANT helicopter designed to fly with advanced agility and maneuverability at twice the speed and range of current conventional helicopters. Jointly developed for the U.S. Army’s Joint Multi-Role technology demonstrator program, the new rotorcraft design is intended to help inform the next generation of military helicopters as part of the U.S. Army's Future Vertical Lift (FVL) program.
During Consumer Electronics Show (CES) 2019, Hyundai debuted it “Elevate” concept: a modular electric vehicle (EV) that can transition between driving on flat surfaces and “walking” over treacherous terrain.
The AS2 from Aerion in Reno, Nevada, will be the first supersonic business jet to market, Boeing officials in Chicago predict. Boeing (NYSE:BA) is providing engineering, industrial, and financial resources in partnership with Aerion to accelerate technology development and aircraft design, with the goal of bringing supersonic air travel to new markets.
In March, a new demonstrator engine by Rolls-Royce, featuring a cutting-edge lean-burn and low-emissions combustion system for future jet engine programs, began icing tests at the Global Aerospace Centre for Icing and Environmental Research in Manitoba, Canada.
LiquidPiston Inc. has developed a new engine that can run on multiple fuels, including diesel, jet fuel, and gasoline. This platform uses an optimized thermodynamic cycle and a new rotary engine architecture and could increases flight endurance over conventional UAV engines by greater than 50%.
A week prior to officially revealing its new N67 200 kVA Stage V solution installed on a genset frame concept at the Middle East Electricity show, FPT Industrial gave a sneak peek of the generator—in virtual form—to select international media at Pregnana Milanese, where about 90% of the company’s engines for power generation are produced.
Aerion and Skunk Works are already collaborating on the engineering of the AS2, while GE will be adapting one of its proven cores with a new low-pressure turbine to be fuel efficient at both subsonic and supersonic flight.
The X-59 utilizes a long and slender airframe to achieve supersonic speeds without causing a high decibel sonic boom. The unconventional design precludes the use of a forward-looking window or viewport. Collins Aerospace is providing a dual multi-spectral enhanced vision system to give pilots a forward view of the airspace.
Orbex, a developer of small satellite (smallsat) launch vehicles based in Forres, Scotland, has unveiled its “Prime” launch vehicle. The rocket utilizes several novel technologies, including the world’s largest metal rocket engine produced as a single piece through additive manufacturing (AM).
Paris-based Safran SA and Munich-based MTU Aero Engines AG will partner to develop, produce, and support a new turbofan engine for “New Generation Fighter” (NGF) aircraft being developed by Airbus SE and Dassault Aviation SA. The NGF is a manned, sixth-generation fighter and a component of the future Franco-German Future Combat Air System (FCAS) architecture.
The supplier revealed a range of waste heat recovery technologies for heavy-duty diesel engines at the IAA Commercial Vehicles show in Hanover, Germany, as well as variable valve timing systems, highlighting their potential to reduce fuel consumption and help reduce emissions.
The WLTP and other 'real-world' vehicle test cycles offer new lubrication opportunities for engine designers striving to make further improvements to power units. BP Castrol's chief engineer details what can be done.
