Robert Hauschild Liebeck is an American aerodynamicist,[1] professor[2] and aerospace engineer at the Boeing Company.[3] He currently heads Boeing's blended wing body program[4][5] and has been a member of the National Academy of Engineering since 1992.[3][6] He is best known for his contributions to aircraft design[6] and his aerodynamic airfoil designs known as the "Liebeck airfoil".[7]

Education[edit]

Liebeck pursued studies in aerospace engineering at the University of Illinois at Urbana–Champaign. He graduated with a Bachelor of Science in 1961, a Master of Science in 1962 and a PhD in 1968.[2][8][9][10] It was while pursuing his PhD that he produced the first airfoil designs known as the "Liebeck airfoil".[3][9][10]

Career[edit]

Liebeck worked summers at the Douglas Aircraft Company, located in Santa Monica, California,[4] until he joined the permanent staff in 1968.[3] He remained with the company after its merger with McDonnell Douglas, which later merged with Boeing in 1997.[4][11] He has managed several of Boeing's airplane programs through which several advanced-concept aircraft were designed.[3][9][10] He now serves as program manager of the company's blended wing body program.[6]

Designs[edit]

Liebeck airfoils[edit]

Designs made by Liebeck during research for his doctoral thesis "Optimization of Airfoils for Maximum Lift", have been applied to the design of high-altitude aircraft. This class of airfoils has been used by NASCAR in its Car of Tomorrow which debuted in 2007.[3]

Blended wing body[edit]

Boeing has invested in a blended wing body airplane program since 1993, a program which Liebeck manages.[4] Run through Boeing's Phantom Works division, the program has been researching, designing and prototyping a new aircraft design which would reduce energy consumption and noise production.[8][9] Initially funded by a grant from NASA of $90,000, the aircraft design moves away from the usual tube-and-wing design and instead has the wings blended into the body.[4] This design was developed by Liebeck, in conjunction with other members of the research team.[6][8] Liebeck's team first released a remote-driven model, the X-48, in 1997, and several others subsequently.[3][6][8][10][12]

Other designs[edit]

Lieback has designed wings for Indianapolis 500 and Formula One racing cars and the keel for the America³ yacht which won the 1992 America's Cup.[3][6] He has also designed propellers and wings for race cars.[3][6][8] He designed the wing for NASCAR's "Car of Tomorrow" in 2007.[8][9][10]

Teaching career[edit]

Liebeck has lectured in aerodynamics and aircraft design courses at several universities.[6] Since 1995 he has been a Professor of the Practice of Aerodynamics at the Massachusetts Institute of Technology where he lectures in aeronautics.[3][8][9][10] Since 2000, Liebeck has also been an adjunct professor at the University of California, Irvine.[3][6] He was also an adjunct professor teaching aerodynamics, flight mechanics and airplane design at the University of Southern California from 1977 to 2000.[3][8]

Awards and recognition[edit]

Lieback was presented with the Brigadier General Charles E. "Chuck" Yeager International Aeronautical Achievement Award in 2012.[6] In 2011 Liebeck was inducted into the Hall of Fame at the College of Engineering at Illinois, an honor which "recognizes Illinois engineering alumni, and others affiliated with the college, who have made significant achievements in leadership, entrepreneurship, and innovation of great impact to society".[6][8] That same year he was presented with "Engineering the Future" award from the Henry Samueli School of Engineering for his work in aeronautics and contributions to the school.[6] Lieback was also awarded:
