Velocity Corrections in Generalized Hohmann and Bi-elliptic Transfer Orbits

摘要

For generalized Hohmann and bi-elliptic transfer orbits, we applied small tangential impulses at peri-apse and apo-apse to acquire the precise destination of elliptic orbit stemming from an initial orbit. There are four cases for this correctional or improvement process. We took into consideration the first configuration for the time being. We determined the four relationships connecting the increments in major axes and eccentricities with the correctional increments in velocities ΔV_A, ΔV_B at points A, B for the generalized Hohmann case. We assigned the three relation-ships-for the bi-elliptic transfer-connecting slight changes in major axes with small increments in velocities at points A, B, C due to motor thrusts.
