BIOGRAPHY

Dr Ifti joined Prof Stuart Laurence's Lab (HAPL) at the University of Maryland in April 2022. Originally from Mymensingh, Bangladesh, he earned his DPhil in Engineering Science (Hypersonics) from the University of Oxford, United Kingdom, under the supervision of Prof Matthew McGilvray. For the scientific contributions in his doctoral thesis entitle, “Transpiration Cooling of a Hypersonic Vehicle,” he won the 2022 UK Doctoral Researcher Award (2nd Prize, Engineering), in a UK-wide academic competition that is awarded annually to junior researchers with promise to be amongst the world class academics of the future. Dr Ifti holds bachelor’s and master’s degrees in Aerospace Engineering from the University of Stuttgart, Germany. Outside the lab, he spends most of his time reading nonfiction books in noisy cafes and playing the game of Cricket. During his time at Oxford, he played for Wolfson College as a right-handed batsman and an off-spinner.

Instructor; ENAE488P: Hypersonic Aerodynamics

Topics: aerodynamics of high-speed vehicles, focusing on both qualitative flow features and the computation of forces/moments and surface heating. Topics to be covered include: general flow relations in the high-Mach-number limit; hypersonic similitude and Mach-number independence; the blast-wave analogy; Newtonian flow and surface inclination methods; re-entry shapes and waveriders; shock-wave reflections and interactions; hypersonic boundary layers; surface heating and viscous forces in hypersonic flows; transition and turbulence; viscous interactions; experimental facilities.

 

Teaching Assistant; ENAE482 Hypersonic Vehicle Design Capstone Project (Instructor: Dr Kevin Bowcutt, Chief of Hypersonics, Boeing)

Senior capstone design course in the aeronautics track. Introduction of computerized methods for sizing and performance analysis. More comprehensive methods to predict weight, aerodynamics and propulsion system characteristics. Consideration in design disciplines such as vulnerability, maintainability, produceability, etc. Groups of students will complete, brief and report on a major design study to specific requirements.
