Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD) has successfully hot-fire tested a full-scale, additively manufactured thrust chamber assembly for the RL10 rocket engine that was built from a copper alloy using selective laser melting (SLM) technology, which is often referred to as 3-D printing.
"We believe this is the largest copper-alloy thrust chamber ever built with 3-D printing and successfully tested," said Additive Manufacturing Program Manager Jeff Haynes. "Producing aerospace-quality components with additive manufacturing is challenging. Producing them with a high-thermal-conductivity copper alloy using SLM technology is even more difficult. Infusing this technology into full-scale rocket engines is truly transformative as it opens up new design possibilities for our engineers and paves the way for a new generation of low-cost rocket engines."
Austrian manufacturer Diamond Aircraft is making its first foray into the helicopter market, with the unveiling at Aero of the DART 280 light-single piston-engined rotorcraft concept.

The Hamilton aEro Twister is a very light and efficient aircraft certified to fly aerobatics between +6 and -4 G. The fiberglass airframe is stiffened and strengthened by carbon elements, while the engine provides up to 100 KW power and a 45 minute-flight autonomy, including 15 minutes of aerobatics. The weight/power ratio is 4.2kg per KW, a ratio quite similar to an Extra 200, providing the required performance needed for aerobatic training.
Safety is a main topic topic as the plane can be used for demonstrations but also for beginners to train and therefore needs to be easy to operate. The Siemens engine proved its ability already in the air and is very reliable. Each battery cell has its own processor to control and monitor the situation: in case of overheating, up to 10% of cells can be switched off independently, allowing the pilot to fly back to the airport safely.
Another key aspect is sustainability and ecology. The plane defines a new way of flying by being CO2 neutral and emitting a very low noise profile. Together with other developments, this project supports the future of aviation through environmental-friendly initiatives and a long term vision. Finally, cost is also lower – about 2/5th of a regular aerobatic plane – and is aimed at attracting not only experienced aerobatic pilots but also young people who cannot currently afford to start the immense adventure of flying a plane upside down.
Dublin, April 06, 2017 (GLOBE NEWSWIRE) -- Research and Markets has announced the addition of the "Manned Electric Aircraft 2017-2027 Hybrid & Pure Electric Technology Roadmap, Market Forecasts, Companies, Models, MEA" report to their offering.
The coverage in the report includes 2017-2027 forecasts of low and high priced electric aircraft sales by number, unit price and market value and a view of figures up to 2031 including assessments by several leading players. The subject matter includes looking at how electric aircraft have largely followed electric land and water vehicles. Pure electric small ones appeared first, about 50 years after the first electric boats and cars. Hybrid ones are needed for the longer distances and tougher duty cycles and only now are these getting serious investment.
The report finds that the delays are only partly explained by the tougher demands and regulatory requirements of aircraft and how things are now changing with much larger commitments. In 2016, Siemens and Airbus agreed to pool 200 engineers to work on them, the level of effort Toyota allotted to hybrid cars twenty years earlier, with major commercial success resulting today. Toyota enjoys well over $20 billion dollars of sales of electric cars, buses and forklifts with Honda and BMW successful too - interesting because all three are now tackling aircraft. Indeed, Google and Facebook are involved in electric cars and aircraft and Apple is interested so it is wake up time. The report analyses the opportunities in new aircraft and their changing key components.
This report of over 190 slide format pages is replete with new forecasts, analysis and infographics seeing the future. The key parts of recent presentations by all the key players are embedded in this work, almost entirely researched in 2016 and early 2017 by award winning PhD level analysts travelling worldwide. Interviews, analyst databases, web searches and conference attendance were extensively used. Old information is useless in this now fast moving field.
