New features for the industry-standard resistance and propulsion software, HydroComp's NavCad. Many contemporary marine vehicles are being outfitted with contra-rotating propellers (CRP), and naval ...

Serious engineering work on contra-rotating open rotors for aircraft propulsion dates back to the late 1940s, particularly as a means to enhance fuel efficiency and extend the endurance of long-range ...

这篇综述深入探讨了Shaft-Driven Variable-Speed Contra-Rotating Propeller Reversible Pump Turbines（SDCRRPTs）对水生生态的影响，通过CFD模拟和BioPA工具评估了两种原型设计对鲑鱼和鳗鱼的生物力学压力机制（如剪切应力、碰撞），为平衡可再生能源生产与生态保护提供了优化方案。

WHEN A MODIFIED MD-80 airliner flew at the 1988 Farnborough air show in Britain, it was supposed to represent the future of air travel. One of its rear-mounted jet engines had been replaced with an ...

The Russian Tu-95 'Bear' isn't just a relic of the Cold War, with the potential for a nuclear payload capable of untold devastation. It's eight contra-rotating propellers also enable to it hold the ...

Precious Metal is a staple of the air racing community. The highly modified P-51's striking yellow and polished paint job and its contra-rotating propellers are features that make it stand out, but ...

Development in 2021 for HydroComp PropElements offers new features across the range of applications, including improved wake-adapted propeller design and analysis. PropElements + FINE/Marine coupling ...
