Computational Analysis of Powered Lift Augmentation for the LEAPTech Distributed Electric Propulsion Wing

Abstract: A computational study of a distributed electric propulsion wing with a 40deg flap deflection has been completed using FUN3D. Two lift-augmentation power conditions were compared with the power-off configuration on the high-lift wing (40deg flap) at a 73 mph freestream flow and for a range of angles of attack from -5 degrees to 14 degrees. The computational study also included investigating the benefit of corotating versus counter-rotating propeller spin direction to powered-lift performance. ...

Accelerating particles—but not just for the LHC

This week, the Large Hadron Collider (LHC) was in technical stop, but particles continued to circulate in the other accelerators. This is because the chain of four injectors that feed the LHC also supplies particles to myriad experiments across several experimental areas.

A chemically functional phosphorus version of natural rubber

Goodyear's 1839 discovery of the vulcanization of natural rubber obtained from rubber trees marks the beginning of the modern rubber industry. A variety of synthetic rubber products were subsequently developed. In the journal Angewandte Chemie, scientists have now introduced a new, interesting variant: a phosphorus-containing rubber with a structure that corresponds to that of natural rubber.
