Aeronautical Engineer Richard Whitcomb literally changed the shape of modern aviation when he designed the "Coke bottle" fuselage - a narrow-waisted plane body that helps high-speed jets to slip through the sound barrier into supersonic flight. Now, 18 years later, Whitcomb has done it again. He has de veloped a radically new wing that will allow subsonic jets to fly faster, more smoothly and more efficiently...
...today's jetliners, if a pilot allows his speed to reach 85% of the speed of sound, a bell rings and a light flash es to caution him to go no faster. There is good reason for the warning. Beyond that limit, the big ships generate turbulence that causes a drastic loss in efficiency and sometimes dangerous buf feting. Thus, although the sonic barrier is around 660 m.p.h. at the normal jet cruising altitude of 35,000 ft., commercial jets are held down to a speed of about 560 m.p.h...
...long distance events and the weight classes. Roy Shaw--who sparkled in a come-from-behind mile win in last Saturday's G.B.C.T. meet--Tom Spengler, and Jon Ensco provide the team with its mile power, and Shaw and Ensco also combine to give the Crimson winning speed...
...struck by an ingenious idea. If mass becomes imaginary at high velocities, why not see what happens when an imaginary number is substituted for mass at rest? When he made the substitution, he was able to derive a real number for the energy of a particle traveling above the speed of light. Translating this concept into physical terms, Feinberg conjured up a strange particle that seemed to exist only on the other side of the speed-of-light barrier; it could move at velocities greater than 186,000 m.p.s., but never at that speed or slower. Thus, because it could...
According to the relativity equations, that "tachyon" (a name that Feinberg coined from the Greek word for "swift") should have other strange characteristics. Unlike familiar particles, which gam mass and energy as they accelerate toward the speed of light, Femberg's particle would lose mass and energy as it accelerated beyond the light barrier. At infinite speeds, it would theoretically have no mass or energy at all. Like a plane going faster than the speed of sound, a tachyon with an electrical charge would generate a "light boom" as it traveled faster than 186,000 m.p.s. The boom would...
