The electron density distribution over re-entry bodies of the blunt sphere cone class at angle-of-attack to the hypersonic free stream is studied in this report. The shock layer is considered as a mixture of dissociated and ionized air species chemically reacting at finite nonzero rates to produce electrons which are distributed three dimensionally by the nonzero angle-of- attack. Both the viscous three dimensional boundary layer and inviscid flow are included in the study. A numerical implicit finite difference scheme is utilized in the method of solution. Results are given in this report for the hypersonic flow over the AFCRL Trailblazer II body at the angle-of-attack of 12 degrees for the two altitudes of 240,000 ft and 220,000 ft.
