Abstract:

The marked advances achieved in the last few years in fluid dynamics can be related to the development of increasingly powerful computers of easy manipulation, new numerical methods, modern test facilities and improved data recording and processing systems. Thus an increasing amount of reliable information has become available. The state of progress reached has opened the way for improved modeling of turbulent events and allowed more and more complex problems to be investigated. For the same reason a market step forward has simultaneously been made in the field of interior ballistics. In particular, important advances are being achieved in improving the methods of analysing and predicting fluid flows in interior ballistics. At the same time new techniques are being developed in the field of propulsion especially as far as liquid propellants are concerned which give rise to new and specific problems. It was therefore considered worth while to verify the extent to which the experts in interior ballistics could take advantage of the progress recently achieved, both theoretically and experimentally, in fluid dynamics. Toward this end the AGARD Fluid Dynamics Panel decided to create a Working Group AGARD FDPWG.05 with experts in interior ballistics from six NATO countries Belgium, France, Germany, Great Britain, Netherlands, and the United States. One chapter deals with the gaseous outflow from tube launchers. One chapter is concerned with the physical and thermodynamic characteristics of propellant gases. One chapter is devoted to a few specific problems encountered in interior ballistics liquid propellants, behaviour of anti-erosive additives, behaviour of solid propellants at high pressures.
