- Abstract
A Conceptual study on an innovative PAGS(Pseudo Anti-Gravity Spaceship) sustained by persistent MoN(Momentum Network) is newly presented in this paper. A few theoretical feasibility study results are included here. The basic principle of obtaining “anti-gravity” force of PAGS is to constitute a triangle or a quadrangle constellation of low earth orbit satellites, and to transmit massive energy beam or mass flow(called as “momentum link”) toward another satellite with reflectors of very high energy efficiency and good precision. Steady outer-going force is generated when the direction of the beam or mass flow is changed by the reflectors, and is maintained so far as the momentum or kinetic energy of the momentum link is unchanged. The key issue is how to produce and maintain the momentum link between satellites so that a sustainable MoN(defined as “a set of momentum links”) can be established. The momentum link can be realized by either very high power laser, or charged/non-charged particle beams, or nano space robots. It is hypothetically assumed in this paper that the total momentum is well preserved by successive transfer of it inside the MoN. The PAGS can be geo-stationary even at much lower altitude than 36,500km from the earth since the pseudo anti-gravity force compensates the force difference between the gravitational force and the centrifugal force of the PAGS. Under this condition, the energy required to build MoN is proportional to the gravitational force on PAGS, and it is found to be of same order of the energy of a PAGS regardless the velocity or the mass of momentum link. Furthermore, it is proven that the total energy required to launch 3 PAGS on orbit and the energy to build MoN is exactly the same as the total energy to launch 3 conventional satellites of same mass on the same orbit altitude. Hence no additional energy is required to constitute 3 geo-stationary low earth orbit satellites compared with 3 conventional low earth orbit satellites of same altitude. For a triangle constellation case, the altitude of each PAGS is 8,370km considering the lowest altitude of the momentum links of 1,000km. For a quadrangle constellation case, it becomes 4,050km. In other words 4,050 or 8,370km altitude geo-stationary satellites may exist. Multiple MoN can be used to get non-equator stationary orbit or arbitrary altitude spaceship. A few technical issues to realize this PAGS are covered as well. The energy efficiency and mass loss requirements to keep MoN, the methods for focusing diversified beam and energizing momentum links including ground-supported system are briefly discussed here.
