Abstract:
ONE FAMILY OF SOLUTIONS IS PRESENTED FOR A MONOTONIC TRANSITION FROM A CIRCULAR ORBIT TO AN EQUILIBRIUM GLIDE. It is performed at high lift coefficient and low LD, and terminates at a match point where the prescribed conditions of the glide are met. The vehicle then continues on the glide at a higher value of LD. The high rag required during transition entails the use of a large auxiliary light-weight drag body, which is jettisoned upon arrival at the match point. The presence of this drag body results in a reduction of the total heat load on the vehicle itself. The exact amount of this reduction depends on the details of the design, but it can be typically of the order of 34 in an entry with a peak acceleration of the order of 7 g. As a result, the maximum average vehicle temperature can be made relatively low, with consequent advantages in the structural design, and in the thermal protection of the payload. Author
