As a kind of application of laser propulsion, air‐breathing laser‐spike engine can be designed for aircraft in atmospheric flight. Laser‐spike engine generates thrust using the blast wave induced by laser energy instead of combustion process. This engine uses air as propellant, therefore, it needs no on‐board propellant. For experimental study, a blow‐down type supersonic wind tunnel and spark generator were used. Supersonic wind tunnel blows Mach number 2.5 supersonic flow and a spark generator was used as energy source in place of laser. Flow visualization was performed for 2‐dimensional laser‐spike engine model and numerical simulation of the corresponding case for the experiment was done and compared with experimental case.
