LITA(Laser‐Driven In‐Tube Accelerator) is a new device for the propulsion of projectile under high velocity condition. LITA is a little different from other accelerators in that it needs continuous laser source energy for acceleration process. One of the issues for LITA is the optical design of the projectile, because the focusing point of laser behind projectile decides its performance. Laser‐supported detonation wave is a main energy source mechanism. Present study shows the performance analysis of LITA using computational fluid dynamics (CFD). Laser power, laser energy, laser frequency, laser focusing point, and projectile base geometry play important roles in LITA’s performance. In this research, blast wave produced by explicitly energy input is used.
