Experimental Evaluation of a Thrust Vector Load Cell

Abstract

This report describes the results of an experimental evaluation of a half-scale (physical size) model of a previously analyzed six-component force balance for testing rocket engines. The force range of the model was scaled down from 5000 foot pounds to 200 foot pounds, and structural parameters were scaled to represent those of the full-scale version which was analyzed under Contract F40600-68-C-0004. The evaluation includes the determination of (1) first- and second-order interactions of single and combination loads and (2) the effect of combination loads at expected gimbal points for typical rocket engines. The data which are presented in tabulated form, validate the prior analysis, and demonstrate that short force measuring links, assembled into a compact integral structure, do not result in excessive interactions.
