Résumé : | In this work, the effect of Forward Facing Steps (FFS) and Backward Facing Steps (BFS) on the Hybrid Rocket Engine’s regression rate is investigated through test firings on both a classic cylindrical motor and a two-dimensional slab burner with optical access. It serves as a first experimental investigation into the proposal to distribute a set of steps along any predefined fuel port profile. For the cylindrical motor, asingle FFS or BFS increased the total average regression rate by up to 48 % and 53 % respectively. On the slab burner, the local zones of high regression rate could be directly derived from the optical access during the burn and they correlate precisely to the regression rate profiles of the cylindrical cases. |
