理论上和实际上,载人航天器在运行过程中发生火灾的可能性都比在地面上更大,防火事关载人航天任务的成败。美国和前苏联/俄罗斯在这方面进行了大量的研究,制定了防火规范,建立了数据库。他们的经验和教训表明,随着航天器的大型化、航天任务的复杂化和飞行时间的长期化,发生火灾的可能性显著上升。我国已经成功地实现了载人航天飞行,下一步的载人空间设施的结构更大、运行时间更长,相应地,防火任务更加重要。
In theory and in actuality, manned spacecraft is more likely to have a fire during operation than on the ground, and fire prevention is related to the success or failure of manned space missions. The United States and the former Soviet Union / Russia conducted extensive research in this area, formulated fire prevention codes and established a database. Their experiences and lessons show that with the enlargement of spacecraft, the complexity of space missions and the long-term flight time, the possibility of a fire has risen dramatically. Our country has succeeded in implementing manned space flight. The manned space facilities for the next step have a larger structure and a longer running time. Accordingly, fire prevention tasks are even more important.
