Welcome to Dr. Jayant Sabnis who has Joined AESAC

Primary tabs

Dr. Jayant Sabnis has accepted an appointment to the School of Aerospace Engineering Advisory Council (AESAC).

Dr. Sabnis earned his B.Tech from IIT Bombay in 1975 and Ph.D. from Syracuse University in 1981. He started his career in Propulsion Systems Gas Dynamics in the 80's, where he made significant contributions in the development and application of computational analyses for multi-phase reacting flows in solid and liquid rocket motors. The analytical capability developed during these research programs was used in the failure analyses and design improvements in the Space Shuttle Main Engine, the Solid Rocket Motor as well as a few other solid rockets.

In 1992, Dr. Sabnis joined United Technologies Research Center, where he actively led several R&D programs in propulsion systems and turbomachinery. In 1998, Dr. Sabnis transferred to Pratt & Whitney and assumed responsibility for the Secondary Flow & Heat Transfer discipline and the internal air system integration gas turbine engines. In 1999, he was appointed Director, Mechanical Systems. In this position, Dr. Sabnis led the group in developing analytical approaches to design and analysis of Mechanical Systems and implementation of novel design concepts to manage fluid flows in lubrication systems. In 2002, Dr. Sabnis was appointed Director, Aerodynamics, where he was responsible for all aspects of aerodynamic designs of P&W engines, as well as defining technology programs related to the Aerodynamic Discipline.

 In 2004, Dr. Sabnis assumed responsibility as Chief Engineer, Systems Analysis and Aerodynamics.  In this capacity, he was reponsible for all aspects of engine performance, operability, control and diagnostics, as well as component aerodynamics and acoustics.  He was one of the three Chief Systems Engineers at Pratt & Whitney Engineering, who constitute the System Level Design Review Board for reviews through all phases of Integrated Product Development for all of Pratt & Whitney engines.  Dr. Sabnis was directly responsible for functional design of all P&W Engines.  He led a group of over 800 engineers in Systems Engineering to define engine cycles, component level aerodynamic design for all primay gas path components, the operability requirements as well as the development of engine control and diagnostics system meeting these requirements.

 Dr. Sabnis played the lead role in defining the thermodynamic cycle for the Pratt & Whitney Geared TurbofanTM family as well as securing air-framer/airline acceptance of this step change in engine architecture.  He has also provided the leadership to the team responsible for the aerodynamic design of these engines, which provide over 15% improvement in fuel consumption for the aircraft engines while simultaneously reducing the noise.  The step change in fuel consumption and the noise reduction provided by these engines has enabled the launch of the Mitsubishi Heavy Industries MJET, sole power plant for the next generation E-Jet series regional jets by EMBRAER.  Thus, the engine now powers six different next generation commercial aiarcrafts with orders for about 3,000 engines already in place.

Dr. Sabnis assumed his current role as Vice President, Engineering - Module Centers at Pratt & Whitney in March 2013.  In this role, he is responsible for the Module Center Engineering function that executes the design, development and field support of all the Pratt & Whitney Engines components.

Dr. Sabnis holds six patents and has authored over 20 technical publications.  He is a member of the advisory board for the AIAA Journal of Propulsion and Power.  He is a Fellow of the AIAA and the ASME.
