Dr. Abdus Suttar Khan (1941 – 31 January 2008) was a Bangladeshi Oxford-scholar and an aerospace researcher for four decades with NASA, United Technology, USA and Alstom, a French power generation company.[1] Khan invented more than forty different alloys for commercial application in space shuttles, jet engines, train engines and industrial gas turbines.

Early life and education[edit]

Abdus Suttar Khan was born in Bangladesh in the village of Khagatua, PS Nabinagar, District Brahman Baria.[2]Dr. Khan attended Ratanpur High School and did his intermediate at Comilla Victoria College. After graduating at the top of his class from Dhaka University (DU) with a Bachelor of Science (Honors) in 1962 and Master’s Degree in Chemistry in 1963, Dr. Khan joined the Chemistry department as a lecturer at DU.[citation needed] In 1964, he accepted a scholarship to study in Oxford University and received his PhD degree in Chemistry in 1968.[citation needed]Following his PhD, Khan returned to the Chemistry department of DU as an Associate Professor and worked there until 1973. That year, he left Bangladesh to conduct research in the field of Materials Engineering (alloys) in the United States.[citation needed]

Professional work[edit]

During his career, Khan invented more than forty different alloys. These alloys are designed for the use in the area of high temperature, such as blades of gas turbine or jet engines. They are coated with environmentally resistant coatings to provide protection from oxidation and/or corrosion, high temperature (to prevent thermal fatigue), to provide wear resistance and etc.[3]

These have been commercially applied in space shuttles, advanced commercial jet engines, and US air force jet engines. These alloys made engines lighter, which enabled the aircraft to fly faster. Dr. Khan's work in Switzerland also involved alloys, which increased the speed of train engines and industrial gas turbines.[4][5][6]

One of Khan's inventions, high strength nickel based alloys, were used for increased fuel efficiency in F-15 & F-16 fighter engines. Subsequently, these alloys were declared as 21st Century materials for advanced aircraft engines in the Advanced Manufacturing and Materials Magazine (Popular Science, June 1990).[citation needed]

Commercial products developed[edit]

1) Nano-catalysts developed are used for in fuel flow path in advanced jet engines for high mach propulsion

2) Advanced abrasion resistant materials developed are used for increased fuel efficiencies of US AF fighter engines (Proprietary to United Technologies' Pratt & Whitney)

3) Corrosion & fatigue resistant coatings deposited by cathodic arc process is used in advanced commercial in Pratt & Whiney jet engines (Proprietary to United Technologies' Pratt & Whitney)

4) Electrodeposited wear resistant coatings developed is used in advanced GT24/26 industrial gas turbine engines by Alstom, Switzerland (Proprietary to Alstom, Switzerland)

5) Electrodeposited oxidation-corrosion resistant coatings used by Alstom, Switzerland in Alstom Power GT-11 industrial gas turbine engines (Proprietary to Alstom, Switzerland)

Awards and achievements[edit]

For Dr. Khan's outstanding research and its application in aerospace, he received numerous prestigious awards from NASA, the US Air Force, United Technology, and Alstom. In addition to these achievements, Dr. Khan was a Chartered Scientist (Professional Scientist) of the Royal Society of Chemistry (Great Britain, 2005), Elected Fellow of the Royal Society of Chemistry (Great Britain, 1996), and a member of the American Society of Metals.[citation needed]

Some of his important awards and recognitions include:

1) The ‘1986 United Technologies Special Award’ for contributing the development of high strength nickel based alloys (known as Alloy Y) used for increased fuel efficiency of F-15 & F-16 fighter engines. The Alloy Y was highlighted in Advanced Manufacturing and Materials Magazine (AMM Magazine), 4 August 1986. Subsequently the Alloy Y was declared as 21st Century Materials for advanced aircraft engines.[citation needed]

2) 'United Technologies Research Center Award of Excellence ' for developing a unique manufacturing process for hydrocarbon catalysis for high-speed aircraft & missile propulsion (1994).[citation needed]

3) The hydrocarbon fuel catalyst technology developed under NASA-Air Force contract was declared as enabling technology by NASA and US Air Force in 1992.[citation needed]

4) 'Pratt & Whitney's Special' Award for contribution to development of manufacturing technology for advanced surface protection coatings for use in jet engines (1993)[citation needed]

Retired life[edit]

During his retired life, Dr. Khan was conducting research as an honorary professor at the Department of Mechanical Engineering at Florida State University. While researching there, he tried to establish a Center of Excellence in nanomaterials for research in the area of carbon nanotechnology for applications in materials science and biomaterial technology.

Social achievements[edit]

Besides his scientific achievements, Dr. Khan was also involved in community services in the United States.
