HTPB iri mu lisansi ya roketi ni iki?

Ingufu za roketi zigira uruhare runini mu bikorwa byo gushakisha ikirere. Mu myaka yashize, ubwoko butandukanye bw'ingufu za roketi bwarakozwe kandi bugeragezwa kugira ngo bugere ku musaruro mwiza no gukora neza. Imwe muri izo nyufu ni HTPB, bisobanura polybutadiene ya hydroxyl-terminated. Bitewe n'imiterere yayo myiza, ni lisansi ikoreshwa cyane muri moteri zikomeye za roketi.

Ifumbire ya roketi ya HTPB ni igikoresho gihuza amashanyarazi kigizwe n'amavuta yo gufunga, oxidizer n'ifu y'icyuma. Ifumbire (ni ukuvuga HTPB) ikora nk'isoko y'amavuta kandi igatanga ubuziranenge ku miterere y'ifumbire. Igizwe na polymeri y'uruhererekane rurerure ikorwa binyuze mu guhuza butadiene na alcool, ikayiha ubushobozi bwo gufunga hydroxyl.

Kimwe mu bintu bidasanzwe bya HTTPBni imbaraga nyinshi ifite. Ifite ubushyuhe bwinshi bwo gutwika, bivuze ko ishobora kurekura ingufu nyinshi iyo itwitswe. Ibi bituma iba nziza cyane mu gutwara roketi, kuko uko propellant ikora ingufu nyinshi, niko imbaraga nyinshi zishobora kugerwaho.

Byongeye kandi, HTPB ntabwo ibasha kwangizwa n'ihungabana cyangwa gukururana, bigatuma iba propellant ihamye kandi yizewe. Gukomera kwayo ni ingenzi cyane mu gihe cyo kubibika no gutwara, kandi inkongi iyo ari yo yose ishobora kugira ingaruka mbi cyane. HTTPBbitanga umutekano wo hejuru mu mikorere ugereranije n'ubundi bwoko bw'ibinyabutabire.

Indi nyungu ya HTTPBMuri roketi lisansi ni ubushobozi bwayo bwo gushorwa mu buryo butandukanye n'ingano. Ishobora kugirwamo ibice by'ubuso bikwiranye n'imiterere n'ibisabwa byihariye bya roketi. Ubu buryo bworoshye bwo gukora butuma abahanga mu by'inganda bahindura ibyuma bishyushya kugira ngo binoze umuvuduko wo gutwika no kugera ku miterere y'imikorere yifuza.

Gutwika HTPB muri moteri ya roketi bitanga gaze nyinshi n'umwotsi mwinshi. Umwotsi uturuka kuri propellants zishingiye kuri HTPB uterwa no gushya kutuzuye no kuba hari ibintu bimwe na bimwe bisigaye. Nubwo umwotsi ushobora kuba utari mwiza kuri bimwe mu bikorwa, ushobora kuba ingirakamaro mu gukurikirana inzira ya roketi mu gihe cyo kuyirasa.

Byongeye kandi, HTTPBIbikomoka kuri roketi bigaragaza igipimo cyo gutwika kiri hasi. Iki gipimo cyo gutwika gigenzurwa gituma habaho ikwirakwizwa ry’ibitero rigenzurwa kandi rishobora gutegurwa neza, ibyo bikaba ari ingenzi cyane ku bikorwa bisaba kugenzura no kuyobora neza. Abahanga mu by’imashini bashobora gushushanya neza inzira roketi inyuramo n’inzira inyuramo, bityo bigatuma ubutumwa bugenda neza muri rusange.

Nubwo lisansi ya roketi ya HTPB ifite ibyiza byinshi, inafite imbogamizi zimwe na zimwe. Imwe mu mbogamizi ni uko ihinduka ryihariye rito ugereranije n’andi moko y’imashini zitwara umuriro. Ihindagurika ryihariye ni igipimo cy’uburyo imashini ihindura ingano y’imashini zitwara umuriro neza. Nubwo HTPB itanga ihinduka ryiza, hari zimwe mu mashini zishobora gutanga agaciro kanini k’ihindagurika ryihariye.
