Abstract: Jet blast impingement on concrete is a problem today and will worsen when the new vectored-thrust aircraft become operational. Ground erosion has already been observed under the auxiliary power units of the Air Force B-1 and the Navy FA/18. Tests performed in this study show that explosive spalling will occur in conventional concretes under the extreme heating proposed for future vectored-thrust aircraft. This paper discusses the first phase of research by the Air Force Engineering and Services Center which addresses the issue of alternate materials to meet this problem. Twenty-four samples were tested using the British Aerospace 1/5th scale Ground Erosion Rig at British Aerospace.
