摘要
本文设计了用于试验的化学微推冲器 ,研究了斯蒂酚酸铅和硝酸肼镍在不同药室直径 (0 5～ 1 5mm)和不同药剂配比下的推进性能。实验测得装药量为 0 3～ 2 8mg时斯蒂酚酸铅的推力约为0 0 5～ 0 38mN ,总冲量约为 3 2× 10 - 5～ 3 0× 10 - 4mN·s ;装药量为 1 0～ 3 2mg时 ,硝酸肼镍的推力约为 0 0 6～ 0 2 5mN ,总冲量约为 1 8× 10 - 3～ 1 0× 10 - 2 mN·s.
Micro chemical thrusters having the structure of three layers were designed for experiments. When the propellants used were lead styphnate and nickel hydrazine nitrate respectively, with nitrocellulose as the binder, their thrust properties were studied under different chamber diameters (0.5～1.5mm) charged with different proportion of propellants. Experiments testified that the thrust of lead styphnate was about 0.05～0.38mN, its impulse was about 3.2×10 -5～3.0×10 -4 mN·s in 0.3～2.8mg charges, and the thrust of nickel hydrazine nitrate was about 0.06～0.25mN, its impulse was about 1.8×10 -3～1.0×10 -2 mN·s in 1.0～3.2mg charges.
