Yesterday-Today-Tomor-row—that
is what the Air Force Research Laboratories (AFRL) at Kirtland Air
Force Base, N. M. and the Wright Patterson Air Force Base (WPABF),
Ohio, are all about.
This is where weapon systems
of the future are conceived, tested, modified and tested again and
again until worthy of acceptance. This is where a heritage of a
legendary past spurs aerospace logisticians, engineers and
scientists in a quest to "keep ’em flying", faster, higher, further,
and safer than man has ever flown before.
Three of these Indian Americans such as Biswa
Ganguly, Balu Sekar, Atindra Mitra, Shekhar Guha, Datta Gaitonde and
L. R. Ram Mohan who have settled into their niche working for the
United States Air Force—not as men in uniform, but as civilian
scientists.
And among them are three senior Indian scientists
with a combined total of 80 years service for the Department of
Defence, who were ranked recently as Air Force Leaders and placed
alongside Brigadiers, Generals and Majors.
Meet the trio—Siva S. Banda and Vipperla B.
Venkayya in Ohio and Alok Das in New Mexico. These first-generation
Indian immigrants have created an enviable record that would be
difficult to surpass.
Like other eminent Indian scientists, they have
publications aplenty and patents by the dozen. They have mentored a
generation of younger scientists. They have earned the recognition
of their professional peers. They have been honoured by professional
societies, by academies and by the defence establishment. But more
importantly, the technologies emerging from their work is providing
the basis for maintaining America’s scientific and technical
pre-eminence in the world and for meeting the challenges of the
military.
The Air Vehicles Directorate is at the heart of
the USAF defence system, a defence that will be based increasingly
upon technological advancement. Much of the work here is classified.
It was once reported that a U. S. senator was denied access into a
building at Wright Patterson AFB because it was classified Above Top
Secret.
The technologies emerging from the Air Vehicles
Directorate today is expected to provide the basis for maintaining
America’s technical pre-eminence in the world and for meeting the
challenges of tomorrow.
Take the role of Dr. Siva S. Banda who leads the
Control Science Centre of Excellence at the AFRL where he performs
and directs basic and applied research that supports the future
vision of the Air Force. His primary responsibility is the
transition of basic research results from control theory to the
aerospace industry. After high-level discussions with Air Force
operational personnel in the Air Combat Command, Dr. Banda’s task is
to translate the future Air Force operational needs into a list of
future technologies by enlisting the broader academic community.
This is at the heart of Dr. Banda’s mission.
His current research efforts focus on autonomous
and cooperative control of multiple unmanned air vehicles, guidance
and control of transatmospheric vehicles, aerodynamic flow control
and formation control of micro satellite clusters.
Banda says that the Air Force interest in access
to space and NASA’s focus on the development of the next generation
of reusable launch vehicles has provided new opportunities for
researchers to develop technologies that support the objectives of
civilian and military space programmes. He recently solicited
proposals from scientists that will reduce development costs, reduce
turn-around time and increase overall vehicle safety and
reliability. After earning a Bachelor’s degree in Electrical
Engineering from Regional Engineering College, Warangal (1974),
Banda went on to earn his Ph.D (1980) in aerospace engineering from
the University of Dayton, Ohio. Since then, he has been at WPAFB
beginning his career as an aerospace research engineer and moving
step by step to a leadership role at the AFRL.
Dr. Vipperla B. Venkayya is a senior scientist
with 36 years experience at the AFRL. As a member of the scientific
and professional cadre of senior executives, he performs and directs
research and development at the Multidisciplinary Technologies
Centre in the Air Vehicles Directorate.
Dr. Venkayya is an in-house researcher, programme
manager, consultant, mentor and a technical leader in planning and
evaluating complex technology development projects. He is an
authority and strong advocate of research in modelling and
simulation of complex dynamics problems concerning aeronautics and
space structures. His research interests are in the areas of finite
element analysis, aeroelasticity and multidisciplinary optimisation
of flight vehicle structures. In addition, technology transfer is
one of his important activities at the laboratory
Dr. Venkayya initiated and promoted the planning
and development of ASTROS, a software system for designing airframe
structures that capture essential interactions of flight loads,
aeroelasticity and structures and controls in a mathematical
optimisation setting.
Venkayya and his team have trained more than 700
engineers and scientists over the years in modelling and simulation
of complex structural dynamics problems using known software systems
such as ASTROS and NASTRAN. He has served as consultant to Air Force
centres, NASA, Federal Aviation Administration and the U. S. Navy on
numerous technical projects.
Beginning with a degree in Physics from Andhra
University in 1952, Venkayya earned a Bachelor´s degree in
structural engineering with honours from the Indian Institute of
Technology in 1956. A Masters degree from the University of Missouri
and a Ph.D in structural engineering from the University of Illinois
in 1962 capped his education. After a five year teaching stint at
Suny, Buffalo, Venkayya joined the AFRL at WPAFB in 1967 as senior
aerospace engineer.
Dr. Alok Das is the senior scientist for space
structures and control, Space Vehicles Directorate, AFRL, Kirtland
Air Force Base. Das serves as the chief technologist to the director
of space vehicles in formulating, planning and implementing advanced
concepts and spacecraft technologies for future Defence Department
space systems. After earning B.Sc. and M.Sc. degrees from the Indian
Institute of Science, Bangalore, Das started his career as a
controls engineer at the Indian Space Research Organisation.
Following a two-year stint designing attitude control systems for
some of India´s initial earth observation satellites, he went on to
earn a Ph.D in aerospace engineering from Virginia Polytechnic
Institute. In 1984, he began his career as an aerospace engineer at
the Air Force Rocket Propulsion Laboratory, Edwards Air Force Base,
Calif. As the technical head for the emerging large space structures
area, he developed it into the Defence Department’s premiere
facility for developing and demonstrating advanced technologies for
modelling and precise control of such systems. Later, working
closely with the Ballistic Missile Defence Organisation, NASA and
DARPA, he was instrumental in the development and transition of the
emerging smart structures technology.
