Robert Flemming


Robert Flemming
Sikorsky Aircraft Corp. (Retired)

Robert Flemming earned a bachelor of science degree in aeronautical and astronautical engineering from Purdue in 1967. He received a master of science in engineering science from Rensselaer Polytechnic Institute in 1970.

Mr. Flemming completed a 45-year Sikorsky Aircraft career in June 2012. Prior to retirement, he served in the role of engineering mentor and advisor as a technical fellow (first elected to this position in 2003), while also serving in his technical specialty as the chief of Sikorsky's icing research, development and certification activities. He now has over thirty years of experience in the field of rotorcraft icing, working on both military and civilian helicopters. As an internationally recognized aerodynamicist and aircraft icing expert, referred to as "Dr. Ice" by his Sikorsky coworkers, he has authored or coauthored over 90 technical reports, conference publications and other documents. Thirty six of these publications are publically-available icing reports, articles, and papers.

For over four years, Flemming led the project that resulted in the icing certification of the Sikorsky™ S-92A helicopter (and subsequently for the certification of the S-92A to the EASA limited icing Special Condition) and was involved with the design of the Sikorsky S-76D™ helicopter ice protection system, the Polish PZL Mielec M28 ice protection system improvement and certification program, as well as the conceptual and preliminary design of other helicopter rotor and inlet ice protection systems. He demonstrated the ability to conduct icing research and certification tasks, preparing certification and test plans, defining the methods to meet the Code of Federal Regulations and other requirements, and guiding the overall certification process. He recently completed a task with the FAA to provide material for a rotorcraft icing handbook and supports Butler America for icing activities.

He has extensive experience in icing flight tests, including tanker flight tests, and in icing and aerodynamic laboratory and wind tunnel tests. Icing wind tunnel tests include tests of model rotors, airfoils, air induction/engine systems, and icing instruments. Included in this icing work has been several National Rotorcraft Technology Center projects conducted jointly with other USA rotorcraft companies. He has experience in the use of icing instruments, the application of scaling relationships for rotors, and the fabrication of simulated ice shapes for airfoil research, engine inlets, empennage components, and rotors (simulated ice for the latter not flown due to safety concerns). He has used both rudimentary and more sophisticated analyses to support his work, both for rotorcraft and the M28 fixed-wing airplane. He has studied shed ice effects and witnessed shed ice impact tests that evaluated the potential for rotor blade damage from shed ice. He also has experience in the writing of Failure Hazard Assessment reports and in the safety engineering process for ice protection systems.

During Mr. Flemming's career, he had been in charge of the research laboratories at Sikorsky Aircraft and also had significant roles in the aerodynamic design and wind tunnel and flight testing of advanced airfoils (he is the designer of the Sikorsky SC1094 R8 and SSC-A09 airfoils), the Black Hawk, Comanche and Sikorsky S-92A helicopters, and research aircraft such as the NASA/Army Rotor Systems Research Aircraft (RSRA), the Sikorsky Cypher unmanned helicopter and the Sikorsky X-Wing helicopter. He coordinated and lectured in Sikorsky's "Helicopter Principles" technical lecture series from 2000 to 2012.

Mr. Flemming is a member of the American Helicopter Society (and had leadership roles in its icing committee), of the American Institute of Aeronautics and Astronautics, and of the SAE's AC-9C Aircraft Icing Committee (he has been a member of that committee for the past 27 years, with leadership roles on that committee). He has worked on many SAE panels, writing standards and reports including the SAE rotor ice protection design guide and the codes and tankers recommended practice documents. He has had leadership roles in several international icing conferences and is the co-chair for the 2015 International Conference on Icing scheduled for Prague in June 2015.

Mr. Flemming is an American Helicopter Society Technical Fellow (2009) and was honored with the Sikorsky Donald L. Ferris Lifetime Achievement Award (2005), the American Helicopter Society Howard Hughes Award (2006, and 2014), the Purdue University Outstanding Aerospace Engineer Award (2011), and the SAE Charles M. Manly Memorial Medal Award (2013). He has been awarded two patents for aerodynamic designs, as well as patents for the S-92A dual-channel rotor ice protection system (US Patent 8,550,402), for passive control of ice shedding (US Patent 8,770,512), and for a virtual ice accretion meter display (US Patent 8,779,945). He has one design patent pending for an icing instrument design.

Activities outside of aircraft engineering include membership on the Board of Trustees for the Greater Bridgeport Symphony, coordination of a senior's bowling league, as well as sailing, skiing, and traveling.

Richard Lewis

Vice Chair:

Richard Lewis

Richard Lewis is a certification manager for Airbus in Toulouse and is part of the Airbus expert community. He is the vice-chair of the SAE 2015 International Conference on Icing of Aircraft, Engines, and Structures.

Since leaving University in 1995 with an honours degree in Mechanical Engineering Richard has spent his entire career in the aerospace industry starting as an air systems equipment design engineer before becoming a principal engineer and project manager for Honeywell Aerospace in the UK. It was in these roles that he first encountered aircraft ice protection systems and in 2006 he took the opportunity to join the ice protection team at Airbus UK.

In this role he worked on the design, certification and support of the ice protection systems of the A400M, A380 and single aisle aircraft before moving with his family to Toulouse in 2009 to join the Airbus Product Integrity group. He now focuses primarily on the certification of aircraft for flight in icing conditions, is the Airbus Airworthiness focal point for rulemaking related to aircraft icing and provides certification expertise to research and development programs.

He is the chairman of the EUROCAE working group 89 and has been an industry co-chair of an EASA rulemaking task.

Richard is married with 3 daughters and lives in Toulouse in the South West of France.
