SPACE DIVISION CHRYSLER
IMF CORPORATION

SUPERVISOR, THEORETICAL AERODYNAMICS GROUP
Position

Name J, E. Vaughn____________________________ Clearance SECRET_________

Degree(s) B .S. A.E . Professional Experience 11 Years

Education

Mr. Vaughn received a Bachelor of Science Degree in Aeronautical Engineering from
Auburn University in 1957. Since that time, he has pursued formal studies in Space Mechan­
ics and Space Technology, and has completed the Chrysler Corporation Management Course
in Leadership.

Experience

Mr. Vaughn joined Chrysler in 1960 as an Experimental Aerodynamicist and has con­
tinually advanced to his present capacity of Supervisor, Theoretical Aerodynamics Group.
His assignments during the time he has been with Chrysler have been broad and challenging,
and well qualify him for work of the nature proposed in this RFQ.

When Mr. Vaughn first joined Chrysler, he was placed on direct assignment to the
Aerodynamic Facilities Branch of MSFC. During his three years there, he gained experi­
ence in all phases of experimental aerodynamic testing. Because of the nature of the experi­
mental facilities work, Mr. Vaughn conducted many unique tests that could not utilize con­
ventional facilities. Foremost among these were the Saturn V Cold Flow Launch Deflector
Facility tests. Mr. Vaughn was project engineer for this facility from its inception and was
personally responsible for the engineering design, facility fabrication, and model manufac­
ture . He conducted all initial testing at the facility and through parametric investigations
established the design parameters for Launch Complex 39 at Cape Kennedy. Such parame­
ters as flame deflector turning angle, exhaust flame trench width, height of vehicle above
flame deflector, transporter hole size through which the engines must fire, orientation of
vehicle over flame deflector, and many other critical dimensions were first established at
this facility through Mr. Vaughn’s efforts.

Other assignments while at MSFC included that of project engineer of a pilot model shock
tube. Mr. Vaughn directed the design, manufacture, and installation of this item and gained
a thorough insight of hypersonic flow phenomena. He also acted as 14-inch tunnel project
manager for a while, which gave him further experience in more conventional wind-tunnel
testing.

For the past several years, Mr. Vaughn has worked in-house at Chrysler in the area
of theoretical aerodynamics. He has conducted an analysis of the problem of local flow pro­
perties of axisymmetric shapes and has published a report on the application of Modified
Newtonian Flow Theory to this problem. This work lead him to write a digital computer
program, using this theory, which gives the local flow properties and force parameters of
a variety of vehicle shapes. He has also done extensive work in the area of fluid mechanics
