Julian Allen, who developed the blunt-nosed blunt-nosed missile, stands before an Ames Aeronautical Laboratory wind tunnel at Moffatt Field, Calif. Allen will explain his missle on a TV show. With the United States and Russia on billion dollar missile-making missile-making binges man's conquest of space is moving along as fast as his cleverness can carry him. One of America's brightest hypersonic hy-personic flight (speeds over 3000 mph) experts has given this country's missile effort a powerful power-ful forward thrust with an idea that has rendered the needle-nosed needle-nosed rocket obsolete. Distinguished flight scientist H. Julian Allen of the National Advisory Ad-visory Commitete for Aeronautics Aeronau-tics and the Ames Aeronautical Laboratory has suggested and then proved that a blunt nosed object could re-enter the earth's atmosphere without burning itself it-self up in the ensuing friction. For years, aerodynamicists have reasoned that to minimize aerodynamic drag on a projectile re-entering the thick atmosphere from outer space, a sharp needle nose would be essenial. Allen demonstrated first on the drawing draw-ing board and then with wind tunnels and finally in space itself it-self that the pat conception was wrong. While his blunt shaped missile builds up incredible temperature through friction when contacting the atmosphere, the stub nose creates a wide angle shock wave which carries off much of the heat, keeping the temperature of the object's nose cone within acceptable ac-ceptable limits. This missile innovation and other highly significant scientific accomplishments of the man who solved a major problem of ballistic bal-listic missilemen will be one of the principal subjects of "Conquest," "Con-quest," presented Sunday, Jan. 19 on Channel 5 at 4 p.m. The new science show will deliver de-liver an exclusive report on Allen, Al-len, chief of the high speed research re-search division. Numbered in his contributions to our understanding of airflow around missiles and airplanes is now well known theory for predicting pre-dicting pressures on objects traveling trav-eling at supersonic speeds. |
