The evolution of hydro-abrasive waterjet cutting has been remarkable and is one of the most effective methods of machining. There is no heat affected zone (HAZ), the small cutting widths and omni-directional cutting means we can machine virtually any material with high precision and accuracy. As a result, waterjet cutting produces a much-improved product finish with little to no secondary processing needed.
Advanced technology and methods make waterjet cutting far more environmentally friendly. So much so that the dust, chippings or gas produced with other cutting methods do not occur. There is also no need to change tool heads, blades or lubricants for each type of material which means machining time is greatly reduced.
This highly versatile cutting method produces much less waste than other forms of cutting which allows for more diverse design. The ability to cut more intricate designs and patterns offers Continue reading →
Flying cars are once again a hot topic of discussion but this time it involves Metro Skyways, a subsidiary of Israel’s Urban Aeronautics (UA). The company has announced that they are going into the full-scale development of the CityHawk VTOL flying car. The first manned flights of this hybrid-powered six-seater will take place in 2021 followed by full FAA certification. They plan to convert the CityHawk to run on hydrogen fuel cells after the launch.
Urban Aeronautics Ltd has developed advanced aerodynamic technologies that form the basis of a new internal rotor (ducted fan) aircraft known as Fancraft™. They capitalise on their extensive portfolio through two subsidiary companies, Tactical Robotics Ltd and Metro Skyways Ltd. Both companies are developing unique Fancraft™ for specific markets. The CityHawk, wingless flying car with “land anywhere” technology is their latest project and looks impressive, to say the least. Continue reading →
What does Uber have in common with NASA and the US Army? Well, nothing really besides the new partnership for developing commercial flying taxis by 2023. The new UberAir service wants to launch electric flying taxis within the next five years and working with NASA and the US Army may just realise those ambitions. Continue reading →
Flying cars have been in the news all over the world and competition is rife to produce the first commercial model. Besides finding the perfect balance between road and air capabilities, companies need to contend with legal, safety and regulatory issues. At this year’s Geneva Motor Show, Dutch company PAL-V certainly raised some eyebrows with their road-legal Liberty flying car.
Firmly in the driving seat of innovation, the PAL-V Liberty is set to undergo compliance demonstrations after the Geneva Motor Show. This is the final step in the certification process where we could very well see the world’s first flying car take to the skies as early as 2019. Continue reading →
Naval warfare could be on the brink of a total makeover through cutting-edge technology and innovation. Making waves at the center is the Sea Hunter – a new breed of unmanned, autonomous vessels launched in 2016. It forms part of the DARPA Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) program. DARPA has already completed trials of a prototype unmanned submarine hunter and claims it could lead to a new class military vessel. Continue reading →
