Abstract

In this paper, we propose a propulsion device by Knudsen pump which applies thermal creep flow. The thermal creep flow is characteristic flow of rarefied gas, and it is induced when boundary walls have temperature gradient. We performed experiments and ascertained the thermal creep flow, and the pressure rise. We consider that we can apply the high temperature of the sunlight part while the satellite is flying, and that we utilize it to propulsion device. We also examine the availability of Knudsen pump by simulation of DSMC method.
