Description
Technical field
The invention belongs to Trend of Laser Propulsion Technology field, the target band being specifically related to a kind of nitrine family macromolecule sensitization type high energy ablator and preparation method thereof and preparing with it.
Background technology
Laser micro-propulsion technology can realize gesture stability and the track maintenance of moonlet, have that momentum bit is little, mass of system be light, adjustable thrust wide ranges, without advantages such as nozzle arrangements, operating mode many employings transmission-type, has irreplaceable status in micromass culture field, space.Due to the restriction of moonlet in weight and energy, the laser apparatus (>=1W) of smaller power must be used, the wavelength that laser apparatus is launched is 100 μ s ~ 200ms near infrared section (930 ~ 980nm), burst length, and the long pulse time defines the macromolecular material that ablator is necessary for low heat conductivity.Current laser micro-propulsion target material is made up of substrate and ablation layer, for ensureing the work-ing life of thruster, target material must have certain length (tens centimetres to hundreds of rice), width (several centimetres), thickness (several microns to hundreds of micron) and amount of deflection (can be wrapped on roller), and ablation layer and substrate will bond firmly.
Different polymer substances is when laser ablation, the specific impulse produced, impulse coupling coefficient, energy transformation ratio have bigger difference, select the material of high specific impulse can meet the needs of laser micro-propulsion gesture stability, the material of heavy impulse percentage coupling can meet the needs of attitude maintenance.Whether according to working medium containing energy, ablation working medium can be divided into inertia working medium and contain can working medium.According to energy conservation, the ablation efficiency of inertia working medium can not more than 100%, if but laser energy can be induced containing can the decomposition reaction of working medium, and under the acting in conjunction of laser energy and chemical energy, the utilising efficiency of laser energy can break through 100%.PVC is best inert media, and its maximum thrust percentage coupling can reach 19dyn/W, and maximum specific impulse can reach 1800s, and most ablation efficiency is 49%.PVC can meet the service requirements of SAT-21 type moonlet and be easy to preparation, but its capacity usage ratio is low, aircraft need carry a large amount of working medium and add weight of equipment, there is the problem that discharge quantity is excessive in continuous use procedure, and the diffusion angle of the splash product of carbon containing is excessive.Owing to being subject to microthruster heavily quantitative limitation, the power of laser apparatus is all restricted with the working medium quality of carrying, so reduce the ablation threshold of working medium, improves ablation efficiency imperative.
The target band design of laser micro-propulsion device is generally divided into reflective and transmission-type two kinds, in transmission-type situation, laser produces thrust by the working medium at the transparent substrates ablation back side of ablation threshold, have compared with reflective and optical lens pollution and light path can be avoided to be easy to build two large outstanding advantages, current research mainly concentrates on transmission-type.The binding mode of transmission-type determine target band be divided into substrate and ablation layer two-layer.
