| Sep 10, 2020 at 14:51 | comment | added | John K | I'm describing how you prevent flutter in a non-hydraulic surface, one operated by cables from a control column, or operated by a servo tab on the trailing edge of the surface and can be moved by air loads, vs one with hydraulically powered surfaces (irreversible hydraulics refers to the fact that airloads can't back drive the surface) where balancing is not required, and inferring that a craft like the Shuttle with hydraulically driven surfaces, will get its flutter resistance from the "rigid" hydraulic connection and not by mass balancing. That, and basic structural stiffness, is about it. | |
