Researchers mimicked the air-trapping tricks of diving bell spiders to create aluminum that stays afloat—even when punctured ...

Controllable pitch propellers adjust blade angle instead of engine speed, letting ships change thrust, direction, and handling instantly. This explains the physics, advantages, and tradeoffs compared ...

Abstract: In order to enhance the performance of existing propellers, a study has been carried out on the adjoint-based optimization of propellers based on reverse engineering. This method facilitates ...

SINTEF has now designed and manufactured new measuring equipment for model testing of contra-rotating propellers. This could be good news for many large ships. “We see that propulsion efficiency ...

At the very crux of engineering is the desire to problem-solve, optimize, and squeeze out every bit of efficiency possible from the system being built. Aircraft design and aeronautical engineering ...

With powerful video generation tools now in the hands of more people than ever, let's take a look at how they work. MIT Technology Review Explains: Let our writers untangle the complex, messy world of ...

With their capability to fly higher, farther, and more efficiently, jet engines have transformed air travel since their introduction. From its origins in the 1930s, the jet engine was a substantial ...

Distributed ducted propellers show immense potential for low-altitude aircraft, but the vast number of possible designs complicates standardized analysis. This research introduces a novel equivalent ...

If running a nonprofit organization is anything like running a relay race, then Andrea Chen and Jess Allen have just completed one of the most extended and carefully choreographed baton handoffs in ...
