【Abstract】 Solar sails reflect photons streaming from the sun and convert some of the energy into thrust. This thrust, though small, is continuous and acts for the life of the mission without the need for any propellant. Solar sails provide a wide range of opportunities for low-cost large ?V-requirements interplanetary missions with many of which may be difficult or even impossible to be carried out with other types of spacecraft propulsion systems. Mechanics and state-of-the-art of solar sail are introduced briefly. The performance parameters and key technology are presented.更多还原
