Sail Acceleration vs Sail Area
Fórmula
## Solar Sail Acceleration A perfectly reflecting solar sail receives momentum from reflected sunlight. ### Formula **a = 2S * A / (c * m * d squared)** - *S* = 1361 W/m2 (solar constant at 1 AU) - *A* = sail area - *c* = speed of light (2.998 x 10^8 m/s) - *m* = total mass - *d* = distance from the Sun in AU The factor of 2 accounts for perfect reflection (momentum change = 2p).
Ejemplo Resuelto
10 000 m2 sail, 100 kg spacecraft, at 1 AU.
- 01a = 2 * 1361 * 10000 / (2.998e8 * 100 * 1)
- 02a = 27 220 000 / 2.998e10
- 03a = 9.08e-4 m/s2
- 04About 92.6 micro-g
Preguntas Frecuentes
How fast can a solar sail go?
Acceleration is continuous so speed builds up over time. After months, a sail can reach speeds unattainable by chemical rockets, especially for interplanetary missions.
Does a solar sail work far from the Sun?
Yes, but acceleration decreases with the square of the distance. Beyond about 5 AU, solar pressure becomes very weak.
Has a solar sail ever been tested?
Yes. JAXA's IKAROS (2010) was the first successful solar sail in interplanetary space. The Planetary Society's LightSail 2 (2019) demonstrated sail propulsion in Earth orbit.
