In this paper a series of viable aeroshell proп¬Ѓles are identiп¬Ѓed for satellites operating in VLEO using a Radial Basis Function-based surrogate model with data generated using both Panel Methods and Discrete Simulation Monte Carlo simulations. It is therefore desirable to reduce the drag in order to either reduce these costs or to extend the operational life. Depending on the mission, this may require a propulsive system to maintain the orbit which costs both fuel mass and volume. However, due to the higher atmospheric density of this region, satellites encounter signiп¬Ѓcantly higher atmospheric drag. Accounting for the loss of internal volume and assuming the reduction in fuel mass results in an equally proportioned reduction in fuel system volume it was observed that only a 13% to 27% reduction was achieved.ДЄB - Operating satellites at altitudes in Very Low Earth Orbit (VLEO) has many advantages. It was demonstrated that a maximum drag reduction of between 21% and 35% was achievable for the proп¬Ѓles when optimizing a bi-conic proп¬Ѓle for minimum drag based on Discreet Simulation Monte Carlo simulations with an energy accommodation coeп¬ѓcient of 0.95.
