Feasibility Study on Design of Self-Erecting Aircraft Shelter

Abstract

This research examined the feasibility of designing and constructing an airtransportable, self-erecting aircraft shelter. Behavior of the shelter during erection and diserection was studied by field testing a 1/4-scale, segmented arch model of semicircular geometry, and by analyzing the behavior of a circular segmental prototype structure. Analyses of the structural behavior of the model and prototype were performed using the matrix-displacement method. Large displacements of the structure were accommodated analytically by use of a procedure of incremental displacement followed by an updating of structure geometry. A computer program (BOOTSTRAP) was developed to perform these analyses. Analyses showed that stable configurations of the 1/4-scale semicircular arch were achieved only when a single internal hinge was allowed in the structure. A satisfactory diserection procedure for the full-scale prototype was not achieved.
