The method is restricted to circular-to-circular in-plane tangential low-thrust maneuvers and incorporates a coast arc to ensure efficient propellant usage. The solution directly links the satellite maneuvers to the resulting ground track location, allowing for straightforward overflight targeting of a given by: 1.

“A Method for Approximating Propellant Requirements of Low-Thrust Trajectories,” NASA TN-D, Ragsac, R. V., “Study of Electric Propulsion for Manned Mars Missions,” Journal of Spacecraft and Rockets, Vol. 4, April , pp. – Inclination changes are difficult and expend a lot of delta-v that could be saved for other maneuvers. Inclination changes are most efficiently performed at apoapsis, where orbital velocity is at its lowest. In some cases, it's more efficient to transfer the vessel to a further orbit, perform the inclination maneuver, and transfer back.
1 spacecraft then employed a combination of low thrust, resonant orbits and the L1 corridor to reach lunar orbit in February after a month transfer7.

Get this from a library. A method of efficient inclination changes for low-thrust spacecraft. [Robert Falck; Leon Gefert; NASA Glenn Research Center.]. I am studying low-thrust maneuvers, in particular a change of inclination only.
According to (Ruggiero et al., ), if one writes the perturbation force in the Gauss planetary equations in terms of yaw and pitch angles $\alpha$ and $\beta$, the expression for the change in inclination is as follows.
In spaceflight, an orbital maneuver (otherwise known as a burn) is the use of propulsion systems to change the orbit of a spacecraft far from Earth (for example those in orbits around the Sun) an orbital maneuver is called a deep-space maneuver (DSM).
[not verified in body]The rest of the flight, especially in a transfer orbit, is called coasting. Non-Keplerian orbits using low thrust, high ISP propulsion systems. Such a catalogue of B orbits enables an efficient method of identifying regions of possible displaced orbits for potential. Spacecraft propulsion is any method used to accelerate spacecraft and artificial propulsion or in-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with launch l methods, both pragmatic and hypothetical, have been developed each having its own drawbacks and advantages.

A Method of Efficient Inclination Changes for Low-Thrust Spacecraft. Fig. 2 shows the scheme of the flight path which is being considered in the preliminary problem.
The trajectory with two swing-bys is analyzed. T 0, T 1, T 2, T f are the date of start, the dates of the 1th and 2nd swing-bys and the date of the SC arrival to the destination planet; t dsm0, t dsm1, t dsm2 – the dates of the impulsive velocity on the heliocentric by: 8.

The practical realisation of electrical propulsion depends on the development of efficient propulsion units and of lightweight power supplies; these and other spacecraft components are discussed, and a number of examples of orbital manoeuvres are given, including close-Earth, far Cited by: 5.
S.1 Spacecraft Propulsion Systems Spacecraft propulsion is based on jet propulsion as used by rocket motors. The principle of rocket propulsion was known as far back as B.C. In the 13th century solid rocket-powered arrows were used by the Chinese military. The Second World War and the cold war advanced rocket missile development in modern time.
Orbital inclination change is an orbital maneuver aimed at changing the inclination of an orbiting body's maneuver is also known as an orbital plane change as the plane of the orbit is tipped.
This maneuver requires a change in the orbital velocity vector at the orbital nodes (i.e. the point where the initial and desired orbits intersect, the line of orbital nodes is defined by the. A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas.
Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as.

Orbital mechanics, also called flight mechanics, is the study of the motions of artificial satellites and space vehicles moving under the influence of forces such as gravity, atmospheric drag, thrust, etc. Orbital mechanics is a modern offshoot of celestial mechanics which is the study of the motions of natural celestial bodies such as the moon and planets.
Low-thrust trajectories can benefit the search for propellant-optimal trajectories, but increases in modeling complexity and computational load remain a challenge for efficient mission design and optimization.
