A former NASA engineer says his propellant-free engine can beat Earth’s gravity, but the real test is whether physics lets it leave the lab

A former NASA engineer claims a new engine can beat gravity without fuel. Is it a breakthrough or just a classic physics trap ...

Physics-informed neural networks for predicting gas flow dynamics and unknown parameters in diesel engines

This paper presents a physics-informed neural network (PINN) approach for monitoring the health of diesel engines. The aim is to evaluate the engine dynamics, identify unknown parameters in a “mean ...
