Professor Emeritus Richard Heckel passed away Tuesday, May 25, in Wisconsin Rapids, Wis., following a battle with pancreatic cancer. Heckel, the former head of the materials science and engineering department at Carnegie Mellon University, was recruited in 1976 by then-President Dale Stein to join the Michigan Tech faculty. For 20 years he was a professor of materials science and engineering, known both for his rigorous teaching and dedication to research. Upon his retirement in 1996, he formed the consulting firm Engineering Trends, capitalizing on his longstanding interest in engineering education.

Abstract

Ceramic matrix composites (ceramic fiber in a ceramic matrix) have the promise ofproviding significant efficiency and durability improvements for gas turbine enginesbecause the material has essentially constant strength with temperature.  Thisallows higher engine operating temperatures without the need for cooling air.  Forany material, the characterization of the material and its resulting performance iskey in determining its usefulness for a given application.  Additionally, long termtesting and resulting residual capability is critical to understanding the durability ofthe material.  Such results will be shown for a characterization effort on novelSiC/SiC and C/SiC material systems.  Results from engine testing will also beshown as well as limited flight testing information.

Biography

Greg Ojard is the Discipline Chief for the Advanced Materials Group in Materials &Processes Engineering at Pratt & Whitney.  He has 18 years of experience in characterizingmaterials for aerospace applications.  He spent his first 5 years developing and performingultrasonic inspections on a wide range of development material and aerospace hardware.  Forthe last 13 years he has worked on characterizing ceramic matrix composites, ceramics andceramic coatings for hot sections in gas turbine engines.  He has been the lead engineer onseveral ceramic matrix composite characterization efforts leading to insertion and flight testopportunities. He holds 2 patents and has over 45 publications. He is also an Adjunct Professorat the University of New Haven teaching materials selection courses.  He earned his PhD fromIowa State University in Metallurgy in 1991.  He has his BS and MS degrees in MetallurgicalEngineering from Michigan Technological University in 1986 and 1988.
