- Abstract
A novel concept of PAG(Pseudo Anti-Gravity) Flying Saucer sustained by Ground MoB (Momentum Beam) is newly proposed in this paper including theoretical feasibility study results. The “anti-gravity” force of PAG Flying Saucer is obtained by reflecting high speed mass flow transmitted from Ground MoB. The “mass flow” could be either water jet or air jet, or particle beam. For the Flying Saucer of altitude 30~100km the velocity of MoB could be a few km/sec and the mass flow rate is several tens of g/sec to lift several tens of kg weight if there is no air drag, where the power needed to generate momentum beam is proportional to both mass flow rate and the square of its velocity, and is found as 100kW~1000kW for 10~100kg weight of Flying Saucer. The velocity of momentum beam is dropping as it goes high due to the earth gravitational force, and becomes eventually zero at some altitude. The maximum range of the beam must be less than 50km for 1km/sec jet from Ground MoB. Furthermore there should be additional velocity drop due to atmospheric impedance, which is roughly evaluated for water jet case in this paper. Considering these velocity drops it is verified that an optimum initial velocity exists which gives maximum lifting force for given power. Ground MoB delivers not only momentum but also energy to the Flying Saucer. An idea to utilize MoB energy is to activate cross rotating turbo-fans so that some amount of mechanical or electrical power can be generated. The mechanical power can be used to give additional lifting and to compensate air drag at relatively low altitude of less than 50km. Flying Saucer can be supported by either single Ground MoB or multi Ground MoB’s, for example 3, to control its spatial position. In case there is any obstacle such as an airplane and a bird, the beam transmission could be spontaneously ceased for 20 seconds which gives 2km altitude drop if multi Ground MoB scheme is not adopted. Furthermore there are various natural hazards such as snow, rain, hailstone, storm, and even cloud. Ground MoB should be so designed to detect and avoid, if possible, or to overcome these obstacles. An idea is to locate Ground MoB as high as possible, or provide a several km long probe to protect the momentum beam from atmospheric disturbances. The probe is not necessarily a mechanical structure but a strong wind tunnel, in which the momentum beam is safely guided. Flying Saucer can be stationary for a few months or many years to provide stationary mission services such as wide range ground monitor, local communication relay, and national security. It is air-pollution free and CO2 free, hence it is a green space technology. The altitude of 30km~100km had not been widely utilized since satellites cannot stay and UAV’s cannot go up to there, however now we have a possible candidate, the PAG Flying Saucer.
