Jacques B. Hadler To Direct Research Activities At Webb

Webb Institute of Naval Architecture has announced the appointment of Jacques B. Hadler as director of Webb's Center for Maritime Studies. In this capacity, he will direct the research activities of Webb Institute. He will join the staff immediately on a part-time basis and assume full responsibilities upon retirement of Prof. Edward V. Lewis on December 31.

A graduate of the U.S. Naval Academy, with his Master of Science degree from Massachusetts Institute of Technology, Mr.

Hadler has had 31 years' experience at the David W. Taylor Naval Ship Research and Development Center in Carderock, Md.

There, he conducted and directed research in the fields of ship resistance, propulsion, marine propellers, vibrations, seakeeping, maneuvering and conceptual ship design. He is the author of numerous technical reports and papers published by The Society of Naval Architects and Marine Engineers, Naval Hydrodynamics Proceedings, International Towing Tank Conference, American Towing Tank Conference, and the Royal Institution of Naval Architects.

In addition to memberships and committee activities with those groups, he is also a member of The Society of Naval Architects of Japan, the honorary research society Sigma Xi, and is a registered professional engineer.

The Center for Maritime Studies has recently announced improved research capabilities in the Robinson Model Basin. A PDP- 11 /05 computer with ancillary equipment has been installed in a new instrument room to record variable tank test data expeditiously and accurately in digital form, and in the case of tests in irregular waves, to make spectral analyses of wave and response records. The wavemaker, of the oscillating plunger type with hydraulic drive, has controls that permit any desired wave spectrum to be simulated. Hence, the facility is ideal for quick, inexpensive studies of loads, motions, forces, accelerations, etc., acting on small models of ships, floating objects or fixed structures. Other facilities include a circulating flow channel, a small structures laboratory, and both in-house and time-shared computer facilities.

An oscillating table for tank sloshing tests is under construction.

Members of the Webb faculty assisting Mr. Hadler in the Center for Maritime Studies are: Norman A. Hamlin, Professor of Naval Architecture; Lawrence W.

Ward, Professor of Engineering (Hydrodynamics) ; Martin Goldberg, Professor of Engineering (Structures); Jens T. Holm, Professor of Marine Engineering; Alan Rowen, Associate Professor of Marine Engineering; and Bruce H. Stephan, Professor of Mathematics.

Robert B. Zubaly, Professor of Naval Architecture at SUNY Maritime College, is a regular part-time Research Associate.

Robert B. Marshall is a part-time Research Associate in Shipping Economics, and D.M.

Mack-Forlist is a consultant in Shipbuilding Management.

Prof. Edward V. Lewis, who has served as director of research since 1961, has accepted a ninemonth appointment at the U.S.

Naval Academy as the NAVSEA Research Professor, Naval Systems Engineering Department. It is planned that Professor Lewis will continue to participate in the research activities as a consultant to the Center for Maritime Studies.
