Noncoplanar orbit transfer of debris remove vehicle needs lots of fuel. In this paper the optimal impulsive design for aeroassisted orbital transfer from Low Earth Orbit (LEO) or Geostationary Earth Orbit (GEO) to LEO with an inclination change is presented. Through comparison of the double-impulsive Hohmann orbit transfer and aeroassisted orbit transfer in noncoplanar orbit, the fuel savings of different altitude or inclination from two noncoplanar orbits are concluded. Results show that the minimum velocity increment of orbit transfer between GEO and LEO is 1.55 km·s~(-1). With the increase of orbital altitude difference, aeroassisted orbital transfer efficiency gradually reduces. Implementation of aeroassisted orbit transfer with the same orbital altitude, low orbit aeroassisted orbit transfer optimization efficiency is higher than that of high orbit. When the value of orbital inclination between two noncoplanar orbits is less than 5°,the fuel consumptions by adopting aeroassisted orbit transfer and double impulse orbit transfer are equal. For aeroassisted orbit transfer optimization between noncoplanar orbits with the same altitude but different orbital inclination difference, with the increase of orbit inclination difference, the fuel saving first increases then decreases, and when the angle is about 20°, the fuel savings rate is the maximum.
