Abstract: To carry out a scaled-model flight test of a high-gain aircraft with a proportional plus integral plus derivative (PID) flight control design, the similarity relations of the flight control ...

Abstract: This paper provides an analysis of the BADA aircraft performance model capabilities and addresses the BADA model ability to provide accurate modeling of aircraft performances over the ...

Millions of tons of microplastics flow into the ocean every year, but tracking the movement and accumulation of those microscopic polymers is difficult. A new study builds a theory of how spherical ...
