  2. Estimation of Reference Area Large Mars Entry Vehicle • Using the Project Legend Mars Habitat Vehicle as a starting point, the volume needed was estimated to be: • V = 1200 m^3 • Three Geometries were looked at. • Aero Shell • S = 346 m^2 • Flat Plate • S = 142 m^2 • Bended Body • S = 200 m^2

  6. Reference Slide • MHV (Project Legend) • 10 m x 20 m x 6 m • V = 1200 m^2 • Aero Shell • Estimated as Cone w/ ¼ sphere on flat face • Letting r = h • r = 10.5m • S = 346.4m^2 • Flat Plate • Estimated as rectangular prisom • Letting b = h and l = 2b • b = 8.43 m • S = 142.1m^2 • Blended Body • Used dimensions for MHV • Letting S = b x l = 10 m x 20 m • S = 200 m^2
