Keeping the single pulse energy of the CO2 laser constant, the impulse coupling coefficients of air-breathing laser propulsion are measured at various air pressures using a high precision impact pendulum system and the corresponding altitude characteristics. The results show that the impulse coupling coefficient is about 35 dyne.s/J with less than 5 percent fluctuation when the air pressure varies from 2.8 x 104 Pa to 1 x 105 Pa and the altitude from 0 km to 10 km. When the air pressure is less than 2.8 x 104 Pa and the altitude is greater than 10 km, the impulse coupling coefficients decrease following a quadric curve. At a pressure of 1 x 103 Pa and altitude of 31 km, the impulse coupling coefficient is only 9.7 dyne.s/J i.e. a drop of 75 percent. These results, which can be explained as due to the angle of the thrust, are consistent with those of German work using a parabolic device.
