...Whittenberger is also directing work on a "pneumatachograph," an apparatus which clocks the amount of airflow and pressure in the breath of polio victims...
...sound with infinite trepidation. The most troublesome speed begins just below Mach I. When a wing is moving at, say, Mach .80, the air passing over it has to hurry to get around its bulge. If, in doing this, it reaches Mach I, violent things may happen. The smooth airflow breaks into turbulence as hard shock waves jump around on the wing (see cut). The drag increases enormously; the wing's lift drops. The buffeting from the irregular airflow may be strong enough to tear the wing apart. This sometimes happens when a fast subsonic airplane dives too rapidly...
...this point, a frightful thing can happen. The shock wave spoils the airflow over the wing, reducing its lift. The plane's nose drops. Faster & faster it dives. Louder screams the shock wave. The pilot struggles helplessly with the controls, but the tail surfaces do not respond normally. They cannot pull the nose up. Down to earth shoots the plane, with the screech of a siren...
...cannot make the sounds p, m, f, v, w. Such people need surgical treatment, or perhaps a mechanical palate. Their main problem is to expel air through the mouth, not the nose. To learn this, they blow soap bubbles and rubber balloons, sometimes hold to their lips an "airflow indicator"-a gadget consisting of a wheel which revolves when air escapes from the mouth, a paper which flutters when air is exhaled from the nose...
Chrysler introduced "Airflow" design in 1934, is ballyhooing streamlining again. The four lines, 26 models, are about one-and-a-half inches lower but wider at seat level. Priced from...
