Development of Sled Structural Design Procedures
Abstract
The major objective of this study was to establish improved design analysis procedures for the design of dual rail and monorail rocket sleds. The work included reviewing and evaluating past analytical studies of rocket sleds and experimental test data for two dual rail and two monorail sleds. Studies were undertaken to identify the major sources of dynamic excitation of rocket sleds. Three major sources of dynamic excitation were identified; rail roughness, unsteady aerodynamic forces and oscillating axial and lateral rocket thrust forces. Rail roughness was found to be the prime source of dynamic excitation during the coast portion of the rocket sled trajectory. During the thrust stage of the trajectory, and especially at burnout, oscillating axial and lateral thrust forces were found to produce sled dynamic loads which were the same order of magnitude as those produced by rail roughness.
