Who is Dick Johnson?
|
Everybody in the world soaring community knows the name, Richard H. (Dick) Johnson. However, many visitors to this web site may not know the name nor his reputation, achievements or qualifications for performing flight test evaluations. The following is presented to introduce Dick Johnson to you:
Beginnings
Education
Professional Career "Dick Johnson, regarded as one of the country’s premier aeronautical engineers, returned from an international soaring competition in Yugoslavia and began retooling the proposal Word and Penisten had developed. While evaluating various ideas on an analog computer, he began defining ways for TI to place a guidance system on a missile with fins. Johnson, along with engineer Ron Hirsch, devised a unique floating head, a so-called “birdie head,” to house the seeker. Their approach enabled the bomb to stay fixed on the laser-designated spot without the use of stabilization gyros or input from the launch craft. The birdie head directed the bomb precisely toward its target." "The seeker was simple. It was low cost. And it gave TI the potential of providing the Air Force with test hardware in a mere 60 days after receiving the $99,000 study contract." "Because of the tight, 60-day deadline, however, Johnson did not have time to conduct full up-wind tunnel modeling, so he improvised, using his own lathe to machine a one-sixteenth-inch scale model of the precision-guided bombs. He then dropped them in a swimming pool to establish critical centers of pressure."
Soaring Dick learned glider performance testing techniques under Dr. August Raspet while attending Mississippi State University. He has published more than 100 sailplane flight-testing related articles, mostly in Soaring Magazine, concerning flight performance measurements and handling qualities of modern sailplanes. Dick's performance data are cited in books on sailplane design; e.g., Sailplanes 1965-2000 by Martin Simons.
