- Abstract
The Laser-driven Flyer system with a single pulses from a Q-switched Nd: glass laser, of 15 ns duration and up to 20J energy, launched the aluminum films of 5µm thickness up to 8.3km/s velocity in Beijing Institute of Spacecrafts Environment Engineering(BISEE) are briefly introduced. The effects of laser parameters on the velocity and integrity of flyer were discussed, the relationships between the flyer velocity and laser energy were presented. The spatial profile of laser beam and the couple between laser beam and the flyer target have significant influence on the characteristic of flyer. The multi-layer films flyer target was found more better than the mono-layer film in increasing the velocity and integrity of the flyer. Some experimental aspects in our efforts on the space debris hypervelocity impacts on the outer surfaces functional of material, such as the thermal control material, window glass, and OSR etc., are reviewed. Though still developing, the Laser-driven flyer technique has been demonstrated promise in simulating micro M/OD hypervelocity impacting effects.
