Application analysis for aeroassisted orbit transfer in noncoplanar orbit debris remove

【摘要】 Noncoplanar orbit transfer of debiris remove vehicle need lots of fuel,this paper presents optimal impulsive design for aeroassisted orbital transfer from low earth orbit(LEO) or geostationary earth orbit(GEO) to low-earth orbit with an inclination change.Through comparison of the double-impusive hohmann orbit transfer and aeroassisted orbit Transfer in noncoplanar orbit,the fuel saving of different altitude or inclination from two noncoplanar orbits are concluded.The results show that minimum Δv of orbit transfer between GEO and LEO is 1.55 km/s.With the increase of orbital altitude difference,aeroassisted orbital transfer efficiency gradually reduce.Implementation of aeroassisted orbit transfer with the same orbital altitude,low orbit aeroassisted orbit transfer optimization efficiency is higher than high orbit.when the value of orbital inclination between two noncoplanar orbits is less than 5°,adopting aeroassisted orbit transfer and double impulse orbit transfer is equal with fuel consumption.Aeroassisted orbit transfer optimization between noncoplanar orbits with different altitude but different orbital inclination difference,with the increase of orbit inclination difference,fuel saving first increases then decreases,when the angle is about 20° fuel savings rate is the maximum.更多还原
