Depositing a reasonable amount of power ahead of a body, that is the so‐called ‘energy deposition,’ is promising for drag reduction in high‐speed flows. This paper experimentally demonstrates that by repetitively depositing laser‐pulse energies up to 80 kHz a quasi‐steady‐state active air spike is built up in the bow shock layer, and an efficiency of energy deposition of up to 600% is obtained. The drag decrease is an almost‐linear function with respect to a laser‐pulse repetition frequency.
