Laurence Joseph Clancy (15 March 1929 - 16 October 2014 [1] ) was an Education Officer in aerodynamics at Royal Air Force College Cranwell where his textbook Aerodynamics became standard.

He was born in Egypt to Alfred Joseph Clancy and Agnes Hunter.[ citation needed ] In 1951 he gained a Bachelor of Science (Hons) degree from the University of Liverpool. [2]

Clancy studied aerodynamics[ when? ] at the College of Aeronautics at RAF Cranfield, where his teachers were Terence Nonweiler, later of Glasgow University, and Geoffrey Lilley, later of Southampton University.[ citation needed ] Clancy qualified as an Education Officer with the RAF and began teaching at Royal Air Force College Cranwell.

After 16 years with the Royal Air Force, Clancy had a long career at the University of Bradford where he served as Dean of Engineering. [1] He was a colleague of John Brian Helliwell.[ citation needed ]

He married Barbara Consterdine in 1952, they separated in 1969. He has 4 children from this marriage, Peter, Helen, Caroline & Jillian. In 1972 he married Eileen Tyne,(Nee Smith), they separated in 1986. He was married to Jane Bingham. [1] from 1992 until his death.

Aerodynamics

Clancy assembled a manuscript from his lectures. In 1975 Pitman published it as the textbook Aerodynamics. It was re-issued in 1978 by John Wiley & Sons, and in 1986 by Longman. A book review in Journal of Fluid Mechanics described the book as follows:

The scope of the book is wide and includes the mechanics of flight and aircraft performance in addition to the usual topics of basic fluid mechanics, aerofoil and wing theory, boundary layer theory, gas dynamics and experimental techniques. [3]

In his preface, Clancy portrayed aerodynamics as both an exact and experimental science:

The true aerodynamicist … must combine [mathematics and experiment], using analysis to deepen and extend his knowledge, but continually experimenting in order to check the validity of his assumptions and to improve his understanding of the physical problem. (page xviii)

Reviewer M.W. for Flight International wrote, "The author has a lucid style and puts across a traditionally difficult subject in such a way that the less prepared reader is able to follow the arguments of even the knottiest topics." [4]

<span class="mw-page-title-main">Aerodynamics</span> Branch of dynamics concerned with studying the motion of air

Aerodynamics is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term aerodynamics is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for the development of heavier-than-air flight and a number of other technologies. Recent work in aerodynamics has focused on issues related to compressible flow, turbulence, and boundary layers and has become increasingly computational in nature.

<span class="mw-page-title-main">Lift (force)</span> Force perpendicular to flow of surrounding fluid

When a fluid flows around an object, the fluid exerts a force on the object. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to counter the force of gravity, but it is defined to act perpendicular to the flow and therefore can act in any direction.

Originally established as a naval aviation training centre during World War I, the College was established as the world's first air academy in 1919. During World War II, the College was closed and its facilities were used as a flying training school. Reopening after the War, the College absorbed the Royal Air Force Technical College in 1966.
