Abstract

For the first time, the atmospheric flight equations of a Tethered Satellite System (TSS) have been derived in this research. An alternative method to acquire the actual aerodynamic and thermodynamic data of a hypersonic flight vehicle investigated using a Tetherod Hypersonic Waverider (THW) as a model. with the previous experience of deriving the dynamic equations of TSS in space, the atmospheric flight equations of a THW with a very long tethered length have been derived. Compared to the other flight equations of a tethered satellite system which were only expressed in terms of tether variables (tether length, in-plane angle, out-of-plane angle), the now flight equations are expressed in terms of both the tether variables and flight variables of a sub-satellite (velocity, flight path angle, heading angle).
