“…In Russia, the laser jet engine (LJE) [13,14] has been demonstrated in both repetitive pulse and continuous wave modes. Experiments used impulse from CO 2 laser ablation and exhaust combustion to drive wire-guided LJE craft toward the laser beam, a distance of some meters, using polymer or liquid propellants and operating in atmospheric or vacuum conditions.…”

“…An ablation-assisted LSP thruster proposed by Rezunkov (Rezunkov et al, 2006) can serve as a propulsion system for atmospheric flight. Air is injected from the top of the beam concentrator mirror and a laser-sustained plasma is generated on the thruster axis by a CW-CO 2 laser.…”

“Beamed Energy Propulsion” is distinguished by its use of a collimated laser or microwave beam that enables long‐distance wireless power supply, no‐fuel airbreathing flight, high heating rates (detonation and ablation) by beam focusing, and other useful features. Remotely powered space propulsion is a potential alternative to chemical and electric propulsion. Compact onboard laser thrusters also provide unique features. This chapter presents a worldwide review of beamed energy propulsion studies, most of which have been reported at the series of International Symposium on Beamed Energy Propulsion (ISBEP).

“…That's the record of vertical and horizontal propelling so far. Russia [5] , Germany [6] , Japan [7] and IECAS [8] also accomplished vertical propulsion successfully, the structure and weight of the light craft they used are different. The success of the examination about vertical laser propulsion confirmed the theory-feasibility of laser propulsion to be used for spaceflight.…”

The air breathing vertical laser propulsion experiment refers to that in the air breathing mode the light craft under the irradiation of incident laser of vertical direction will turn pulse laser energy into the vertical propulsion thrust of the light craft and continue along the fixed rail upward propulsion flight. It is an important experiment to test the minimum single pulse energy, the optimization degree of light craft structure, and the characteristics of turning the laser energy into the thrust. The experiment is to be conducted dozens of meters in height away the ground generally. The article gives a detailed explanation of the whole process of the air breathing vertical propulsion test, including vertical propulsion light craft design, the connections design, the connections performance test, the frictional resistance detection and the whole process of movement performance test. A vertical propulsion tower was used to conduct the single pulse experiment and multi-pulse performance was predicted with a multiple-pulse thrust measuring system. The impulse coupling coefficient was estimated from fight height. Finally, through the experiments of air breathing vertical laser propulsion, the relation of the movement time and flight height was obtained. In the curve, the mean acceleration of the light craft can arrive to 6m/s 2 in the first 20 pulses and the propulsion height can reach 3.5m in 1.12s. After 0.65s, the acceleration of the light craft decreased significantly. The results of the article lay the good foundation for the laser propulsion launch system verification.
