Christine Darden, Ph.D.,she was appointed as the technical leader of NASA’s Sonic Boom Group of the Vehicle Integration Branch of the High Speed Research Program, a role in which she was responsible for developing the sonic boom research program at NASA.
Oct 31, · Quieting the boom – book review Posted on October 31, by jaimeirastorza With the undertitle “The Shaped Sonic Boom Demonstrator and the Quest for Quiet Supersonic Flight”, this ebook is a new release of the NASA ebook series, and comes just after the previous one devoted to the U-2 which was also reviewed here.
InDarden was promoted to the position of aerospace engineer; and, inshe was appointed as the technical leader of NASA’s Sonic Boom Group of the Vehicle Integration Branch of the High Speed Research Program where she was responsible for developing the sonic boom research program internally at NASA.
A sonic boom is the sound associated with the shock waves created whenever an object travelling through the air travels faster than the speed of jacksonmealsmatter.com booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear.
The crack of a supersonic bullet passing overhead or the crack of a bullwhip are examples of a sonic boom in miniature. take-oﬁ/landing and high-speed cruise e–ciency is required.
Noise is an issue caused by the sonic boom that propagates to the ground from the shock waves created by a supersonic airplane and its components.
Details High-speed research, sonic boom FB2
Plotkin and Maglieri gave an overview of the sonic boom research on the state of the art and the problems that need to be solved. As discussed in Chapter 3, a more reasonable aim for sonic boom reduction is to produce “shaped” sonic signatures with an over-pressure limit somewhere between 0 and lb/ft 2 throughout the total sonic boom ground footprint (not just below the aircraft).
Low-boom, shaped signatures are intended to reduce annoyance and minimize the. Jun 21, · InDarden earned a doctorate degree and by she was appointed to the first of a number of management and leadership roles at NASA, including technical leader of.

This report is the first in a series and deals solely with advanced high-speed air-craft, including both subsonic and supersonic. Three other reports to be published in the near future comprise the remaining parts of this assessment.
They are: “Financing and Program Alternatives for Advanced High-Speed Aircraft, ” “Air Service to Small. Research in Supersonic Flight and As the sonic boom from the X-1 propagated across the California desert, this flight became the most significant milestone in aviation since the Wright brothers' epochal first flight at Kill Devil Hills fourty-four years earlier.

Apr 25, · Darden spent about 25 years researching high-speed aerodynamics and sonic boom minimization. She and her husband of 55 years, Walter, live. Apr 25, · Sonic boom is an impulsive noise similar to thunder.
It is caused by an object moving faster than sound -- about miles per hour at sea level. An aircraft traveling through the atmosphere continuously produces air-pressure waves similar to the water. Jan 04, · This report designs a supersonic passenger transport using a novel supersonic bi-directional (SBiDir) flying wing (FW) concept that achieves low sonic boom, low wave drag, and high subsonic performance.
For supersonic flight, the planform is designed to achieve optimum aspect ratio, span, and sweep angle to minimize wave jacksonmealsmatter.com by: 8. When a train nose enters a tunnel at a high speed, an impulsive pressure wave ('tunnel sonic boom' or 'micro-pressure wave') radiates from the tunnel exit and it causes an explosive sound or an.
Sep 10, · Over the next four decades, Darden rose through the ranks at NASA, serving as aerospace engineer, technical leader of the sonic boom research program, deputy program manager in the high-speed research program, and director of Langley’s Office of. Multidisciplinary design of high speed aircraft for improved sonic boom and aerodynamic performance using a multiobjective optimization procedure is addressed.
Optimization procedure for improved sonic boom and aerodynamic performance using a multiobjective formulation technique. American Institute of Aeronautics and Astronautics Inc Cited by: 2.For additional information about this book HIGH-SPEED DREAMS T he new “High Speed Research” program that Congress had approved in was the product of three years’ work by advocates in NASA and in the aircraft industry.
The ﬁrst step in the process noise and sonic boom research element was budgeted for $ million, with Cited by: 4.This operating environment makes these aircraft excellent platforms to carry out research and experiments in a variety of areas -- aerodynamics, propulsion, structures, thermal protection materials, high-speed and high-temperature instrumentation, atmospheric studies, and sonic boom characterization.
