The new tires apparently passed rigorous tests, including being spun at 250 m.p.h. and stabbed with a titanium blade.
The TSA agents probably won't be as impressed with your slender titanium blade things.
The samples were then mixed and homogenised in an acid-washed food blender with a bowl of acrylonitrile styrene plastic and equipped with a titanium blade.
Mark P. Sullivan, a spokesman for Pratt and Whitney in East Hartford, which had refurbished the titanium engine blades for Korean Airlines, said the box was found by a driver for a food company in New York City shortly after it fell off a truck bound for John F. Kennedy International Airport in New York on Jan . 15
The extremely high endurance limit values were observed for patterns and VT8M titanium alloy blades with sharp edges after the high-power ion beam irradiation (pulse number: 15 20 at not high current density, j=60±10 andm2) and vacuum annealing at 500 °C for 2 h.
As an industrial designer who owns the Modern Fan Company, based in Ashland, Ore., Mr. Rezek has designed 10 sleek models, from the lime-green-and-blue UFO, made of die-cast aluminum with titanium-finish blades, to the Industry, which looks like something made from an Erector set.
The titanium-bladed fans are encased in a Kevlar-wrapped aluminium housing and spin so fast that the effect of the impact of a blade coming loose is equivalent to the impact of a one-ton car being dropped from a 200ft cliff.
Recent high-cycle fatigue (HCF) related failures of gas-turbine jet engines have prompted a re-examination of the design methodologies for HCF-critical components, such as titanium alloy turbine blades.
In order to investigate the stress ratio effect on notched fatigue behavior of a turbine engine blade titanium alloy (Ti-8Al-1Mo-1V), notched specimens were employed to perform ultrasonic fatigue experiments up to 1010 cycles at the stress ratios (R) of −1, 0.1 and 0.5.
