Structural Response and Resulting Quantity-Distance Debris Collection Techniques and Results
Abstract
One of the most important factors in locating protective aircraft shelters (PAS) is the quantity of explosives that can be safely stored inside them. The maximum amount of explosives depends upon the distance to other inhabited facilities and the distribution of peak overpressures and debris which might result from an accidental detonation of the stored explosives. Experimental data provide the basis for calculating the minimum separation distance between explosives facilities and other types of base facilities. These separation distances are referred to as explosives quantity-distance (Q-D) criteria and are normally specified as scaled ranges form the source of the explosion. A new aircraft shelter designed by the Norwegians is under construction in Norway and will be used by NATO forces. The front door and other structural details of this shelter differ significantly from the U.S. Third Generation design. These differences have raised questions regarding the applicability of the Q-D criteria derived from previous test programs. The Norwegian and U.S. governments entered into a Memorandum of Understanding to address these concerns. Their test program included the construction of four 1/3 scale structural models of the PAS. These models were subjected to internal detonations of various weights of high explosives. The Norwegian/U.S. design is similar to the U.S. Third Generation PAS design, but differs significantly in the door and structural details. The door is one piece made with two steel plates with stiffeners between the two plates. The arch and rear wall have the same type of shape but there is about three times the steel in the Norwegian U.S. design. This paper will discuss the response of the shelter to different quantities of explosives in terms of structural damage and debris collection/fragment recovery results.
