Laser Ablation Could Boost Jet, Rocket Fuel Efficiency

Facebook X LinkedIn Email
A new approach to the concept of laser propulsion could launch satellites into orbit and push aircraft past Mach 10 with enhanced fuel efficiency. By ablating solid fuel inside a jet nozzle, laser pulses could increase the speed of gas flow out of the system to supersonic speeds. The approach was proposed by Yuri Rezunkov of the Institute of Optoelectronic Instrument Engineering and Alexander Schmidt of the Ioffe Physical Technical Institute in St. Petersburg. Mach number distribution simulation for a supersonic nozzle with an off-axis paraboloid; (a) describes the system without...Read full article

    laser ablation
    Laser ablation is a process that involves the removal or erosion of material from a target surface using laser energy. This technique is widely used in various scientific, industrial, and medical applications. The intense energy from the laser beam interacts with the material, causing it to undergo physical and chemical changes, ultimately leading to its removal. Key features of laser ablation include: Laser energy: A high-energy laser beam is directed onto the surface of a material. The...
