Vertical Flight Society Announces Winner of
2019 Alfred Gessow Best Paper Award

Fairfax, Virginia — The Vertical Flight Society (VFS) announced today the winner of the Society’s prestigious Alfred Gessow Award for the best technical paper at the 75th Annual Forum and Technology Display. This year’s winning paper is from the Aerodynamics session: Helicopter Rotor Boundary Layer Transition Measurement in Forward Flight using an Infrared Camera, by Anthony Gardner of the German Aerospace Center (DLR). The paper is available for sale in the Vertical Flight Library & Online Store.

The selection process, which began in October 2018, was very rigorous. Session chairs selected more than 280 papers from the 375+ abstracts received. At the Forum, the session chairs and technical committee chairs selected the 20 best papers for final consideration. Then the Society’s Deputy Technical Directors for Aeromechanics, Vehicle Design, Vehicle Integrity, System Integration, Systems Engineering, and Operations and Product Support winnowed that number down to six papers. Following that, the VFS Technical Director and a committee of technical experts reviewed and ranked the papers, and in that ranking, determined that the selected paper was the best of the best.

This year’s Forum 75 was held on May 13-16, 2019 in Philadelphia, Pennsylvania. Next year, the Society’s 76th Annual Forum & Technology Display will be held on May 19-21, 2020 in Montreal, Quebec.

Dr. Gardner will receive complimentary travel, registration and lodging to the European Rotorcraft Forum (ERF) in Warsaw, Poland, Sept. 17-20, 2019, where he will present his paper and receive the Alfred Gessow plaque. The award is named after the helicopter pioneer, researcher, author, professor and founder of the rotorcraft center at the University of Maryland now named for him.
