Ngwongwo siri ike siri ike bụ ihe siri ike (ngwakọta nke bekee) nke nwere ike ire n'enweghị ikuku ma n'otu oge ahụ hapụ ọtụtụ oghere ndị na-ekpo ọkụ dị ọkụ. Dị otú ahụ formulations na-eji kee ugboelu nzube na rọketi engines.

Propellants ji dị ka onye ike isi iyi nke rọketi engines. Na mgbakwunye na mmanụ siri ike, e nwekwara gel-like, mmiri mmiri na analogs ngwakọ. Ụdị mmanụ ọ bụla nwere uru na ọghọm. Mmiri mmiri na-emepụta otu akụkụ na abụọ-akụrụngwa (mmanụ + oxidizer). Gelled fuels bụ ikwọ thickened ka a jel obodo site na iji organic asịd. Ngwá ọrụ soda bụ usoro nke gụnyere mmanụ siri ike na oxidant mmiri mmiri.

Ụdị mbụ nke mmanụ akụrụngwa siri ike. Dika onye na-aru oru gunpowder na ihe analogues ji mee ihe, nke eji ya eme ihe agha na maka ime ihe oku. Ugbu a, a na-eji ogige ndị a eme ihe maka iji mepụta obere obere rọketi, dịka mmanụ ụgbọala. Ihe mejupụtara na-enye ohere ịmepụta obere rọketi (ruo mita 0.5 m) maka ọtụtụ narị mita n'ịdị elu.
