Cov roj foob pob hluav taws yog cov khoom siv (cov khoom sib xyaw) uas tuaj yeem hlawv yam tsis muaj cua thiab tib lub sijhawm tso tawm ntau cov roj sib txuas ua kom sov kom sov. Cov khoom sib xyaw no yog siv los tsim lub dav hlau thrust hauv foob pob hluav taws cav.
Rocket roj yog siv los ua lub zog rau lub foob pob hluav taws. Ntxiv nrog rau cov khoom siv roj, kuj tseem muaj cov gel-zoo li, kua thiab hybrid counterparts. Txhua hom roj muaj nws qhov zoo thiab qhov tsis zoo. Cov roj ua kua yog cov khoom siv ib leeg thiab ob lub ntsiab lus (roj + oxidizer). Gelled fuels yog cov khoom sib xyaw ua ke rau lub xeev gel nrog kev pab ntawm cov organic acids. Hybrid fuels yog cov tshuab uas suav nrog cov roj khov thiab cov kua oxidizer.
thawj hom roj foob pob hluav taws tau ua tiav qhov tseeb. Raws li cov khoom siv ua haujlwm, cov hmoov phom thiab nws cov analogues tau siv, uas tau siv rau hauv kev ua tub rog thiab tsim.foob pob hluav taws. Tam sim no cov tebchaw no tsuas yog siv rau kev tsim cov qauv me me foob pob hluav taws, ua foob pob hluav taws roj. Cov muaj pes tsawg leeg tso cai rau koj tso me me (txog 0.5 m) foob pob hluav taws ntau pua meters hauv qhov siab. Lub cav yog lub tog raj kheej me me. Nws tau ntim nrog cov khoom sib tov sib xyaw, uas yog ignited los ntawm cov hlau kub thiab kub hnyiab tau ob peb feeb xwb.
Cov khoom siv foob pob hluav taws roj feem ntau muaj cov oxidizer, roj, thiab cov catalyst kom ruaj khov combustion tom qab muaj pes tsawg leeg tau ignited. Nyob rau hauv thawj lub xeev, cov ntaub ntawv no yog powdery. Txhawm rau kom cov roj foob pob hluav taws tawm ntawm lawv, nws yog ib qho tsim nyog los tsim kom muaj qhov sib xyaw ntom ntom thiab homogeneous sib xyaw uas yuav hlawv rau lub sijhawm ntev, sib npaug thiab tsis tu ncua. Cov khoom siv foob pob hluav taws siv: potassium nitrate ua oxidizer, charcoal (carbon) ua roj, thiab sulfur ua catalyst. Qhov no yog qhov muaj pes tsawg leeg ntawm cov hmoov dub. Qhov thib ob ua ke ntawm cov ntaub ntawv uas siv los ua propellants yog Berthollet ntsev, txhuas los yog magnesium hmoov, thiab sodium chlorate. Cov tshuaj no kuj hu ua hmoov dawb. Cov khoom siv hluav taws xob sib xyaw ua ke rau cov tub rog cuaj luaj tau muab faib ua ballistic (nitroglycerin compressed gunpowder) thiab sib tov, uas yog siv los ua cov channel blocks.
Lub cav foob pob hluav taws ua haujlwm ua haujlwm raws li hauv qab no. Tom qab ignition, cov roj pib hlawv ntawm tus nqi predetermined, ejecting ib tug kub gaseous tshuaj los ntawm ib tug nozzle, uas muab thrust. Roj nyob rau hauv lub cavkub mus txog thaum nws ploj mus. Yog li ntawd, nws yog tsis yooj yim sua kom nres cov txheej txheem thiab tua lub cav kom txog thaum lub muab tub lim hlawv tawm mus rau qhov kawg. Qhov no yog ib qho tsis zoo ntawm cov khoom siv roj cav piv rau lwm cov analogues. Txawm li cas los xij, nyob rau hauv qhov chaw tiag tiag ballistic launch tsheb, cov khoom siv hluav taws xob siv tsuas yog thaum pib ntawm lub davhlau. Hauv cov theem hauv qab no, lwm hom roj foob pob hluav taws tau siv, yog li qhov tsis txaus ntawm cov khoom siv hluav taws xob tsis ua rau muaj teeb meem loj.

Yog qhov yuav tsum tau foob rau tus neeg ua lag luam: cov yam ntxwv ntawm kev cai lij choj ntawm Lavxias Federation, cov xwm txheej uas tus neeg ua lag luam yuav tsum muaj lub foob, tsab ntawv lees paub txog qhov tsis muaj foob, cov qauv sau, qhov zoo thiab cons ntawm kev ua haujlwm nrog lub foob
Qhov xav tau siv luam ntawv yog txiav txim siab los ntawm hom kev ua haujlwm uas tus neeg ua lag luam ua. Feem ntau, thaum ua haujlwm nrog cov neeg siv khoom loj, lub xub ntiag ntawm lub thwj yuav yog qhov tsim nyog rau kev koom tes, txawm tias tsis tas yuav tsum tau ua los ntawm txoj cai. Tab sis thaum ua hauj lwm nrog tsoom fwv txiav txim, luam ntawv yog tsim nyog
Associated petroleum gas: muaj pes tsawg leeg. Natural thiab txuam roj av roj
Roj thiab roj yog cov khoom siv tseem ceeb tshaj plaws hauv ntiaj teb. Associated petroleum gas occupies ib qho chaw tshwj xeeb hauv kev lag luam roj thiab roj. Cov peev txheej no yeej tsis tau siv ua ntej. Tab sis tam sim no tus cwj pwm ntawm qhov muaj txiaj ntsig zoo li no tau hloov pauv
