A THEORETICAL STUDY OF THE MULTISPRING STAGE SEPARATION SYSTEM OF THE BLACK ARROW SATELLITE LAUNCHER.
Abstract
A mathematical model has been developed of a multispring system for the separation of spinning and non-spinning bodies and programmed for a digital computer. This has been applied to the particular study of the second-third stage and third stage satellite separation system of Black Arrow to ascertain how various malfunctions and manufacturing tolerances can affect the tip-off errors. It is shown that strong short stroke unguided springs transmit the smallest tip-off errors. Use of spring guides can only correct the intrinsic instability of springs; if this instability is only present to a negligible degree, guides can actually increase the tip-off errors. It is concluded that guides are necessary for third stage separation on Black Arrow but not for satellite separation. (Author)
