2Feasibility analysis of the angular momentum reversal trajectory via hodograph method for high performance solar sails显示文摘In this paper a new phase space of hodograph method is adopted to investigate and better understand the two-dimensional angular momentum reversal(H-reversal) trajectories for high performance solar sails within a fixed cone angle.As the hodograph method and the H-reversal trajectory are not very common,both of them are briefly introduced.The relationship between them are constructed and addressed with a sample trajectory.How the phase space varies according to the sail quality and the fixed sail cone angle is also studied.Through variation of the phase space,the minimum sail lightness number can be obtained by solving a set of algebraic equations instead of a parameter optimization problem.For a given sail lightness number,there are three types of the two-dimensional possible heliocentric motion,including the spiral inward trajectories towards the Sun,the H-reversal trajectories and the directly outward escape trajectories.The boundaries that separate these different groups are easily determined by using the phase space.Finally,the method and procedures to achieve the feasible region of the H-reversal trajectory with required perihelion distance are presented in detail.ZENG XiangYuan BAOYIN HeXi LI JunFeng GONG ShengPing 2011Science China(Technological Sciences)2011,54,11:3
3Solar sailing trajectory optimization with planetary gravity assist显示文摘Significant propellant mass saving can be obtained with the use of complex multiple intermediate flyby maneuvers for conventional propulsion systems,and trip time also decreases for a portion of the proper solar sail missions.This paper discusses the performance of gravity assist(GA)in the time-optimal control problem of solar sailing with respect to sail lightness number and the energy difference between the initial and final orbit in the rendezvous problem in a two-body model,in which the GA is modeled as a substantial change in the velocity of the sailcraft at the GA time.In addition,this paper presents a method to solve the time-optimal problem of solar sailing with GA in a full ephemeris model,which introduces the third body’s gravity in a dynamic equation.This study builds a set of inner constraints that can describe the GA process accurately.Finally,this study presents an example for evaluating the accuracy and rationality of the two-body model’s simplification of GA by comparison with the full ephemeris model.CAI XingShan LI JunFeng GONG ShengPing 2015Science China(Physics,Mechanics & Astronomy)2015,58,1:3
4Review on solar sail technology显示文摘This paper reviews solar sail trajectory design and dynamics,attitude control,and structural dynamics.Within the area of orbital dynamics,methods relevant to transfer trajectory design and non-Keplerian orbit generation are discussed.Within the area of attitude control,di erent control strategies,including utilisation of solar radiation pressure and conventional actuators,are discussed.Finally,the methods of modelling structural dynamics during and after deployment are discussed,before considering possible future trends in developing of solar sailing missions.Shengping Gong Malcolm Macdonald 2019Astrodynamics2019,3,2:3

16Fuel-optimal trajectory design using solar electric propulsion under power constraints and performance degradation显示文摘The fuel-optimal transfer trajectories using solar electric propulsion are designed considering the power constraints and solar array performance degradation.Three different performance degradation models including linear,positive and negative exponential degradations are used in the analysis of three typical rendezvous missions including Apophis,Venus and Ceres,respectively.The optimal control problem is formulated using the calculus of variations and Pontryagin’s maximum principle,which leads to a bang-bang control that is solved by indirect method combined with a homotopic technique.In demonstrating the effects of the power constraints and solar array performance degradation on the power budget and fuel consumption,the time histories of the power profile and the fuel consumptions are compared for the three missions.This study indicates that it is necessary to consider the power constraints and solar array performance degradation for the SEP-based low-thrust trajectory design,espacially for long-duration outbound flights.ZHANG Peng LI JunFeng GONG ShengPing 2014Science China(Physics,Mechanics & Astronomy)2014,57,6:1
