Lub tswm ciab Roman yog pyrotechnic cov khoom lag luam uas ua rau hluav taws kub ntau lub txim nrog cov sijhawm sib npaug sib luag rau qhov siab txog plaub caug meters. Qhov cuam tshuam ntawm lub tswm ciab Roman, uas yog lub teeb ci luv luv ntawm ntau yam xim, tuaj yeem ua tiav los ntawm lub suab nrov thiab lub suab - cov pops, whistles, crackles thiab tawg ntho luv. Cov txheej txheem ntawm kev tsim lub tswm ciab Roman tau muab faib ua peb ntu loj: kev tsim cov tshuaj khib ntau ntau; cov khoom siv projectile; sau cov tshuaj khib nrog cov plhaub taum.
Nws yog qhov tsim nyog
- Rau lub tswm ciab:
- - Lub raj (ntawv fax, ntawv ntsa, thiab lwm yam),
- - ntawv xov xwm,
- - poov tshuaj nitrate,
- - magnesium shavings,
- - chaw haujlwm zoo kua nplaum.
- Rau cug:
- - cov nplooj ntawv ntau ntawm cov ntawv whatman;
- - gypsum lossis ib thooj ntawm lub tog raj kheej ntoo;
- - kua nplaum;
- - navik (ntev).
- Rau zoo li:
- - ntawv;
- - gypsum;
- - kua nplaum;
- - daim ntawv;
- - Visko qhov quav;
- - cov khoom tawg;
- - hawk;
- - cov hnub qub.
- Raug rho tawm:
- - shells;
- - ntev cug;
- - ntev Visko qhov quav;
- - mos txwv phom;
- - wads (nyiam dua nrog cov kwj dej hauv nruab nrab, yam lag ntseg)
- - hawk.
Cov Lus Qhia
Kauj ruam 1
Ua mortars:
Txhawm rau ua kom cov cug, siv cov ntawv, kis nws nrog kua nplaum thiab ua tib zoo qhwv nws ntawm cov npoo kom txog thaum cov phab ntsa ntawm lub tshuaj khib ncav cuag cov tuab uas xav tau. Tom ntej no, tshem cov tshuaj khib tso tawm los ntawm cov dab thiab qhuav nws. Tom qab ntawd koj rauj ib qho ntawm nws cov xaus nrog plaster (lossis ntoo lub tog raj kheej) ntawm cov kua nplaum, kho lub tog raj kheej nws tus kheej nrog cov ntsia hlau ntxiv (yog tias lub taub loj). Tom qab ua kom huv huv lub ntsaws, ntxig rau ntau daim cardboard wads ncaj qha mus rau hauv qab cug.

Ua zoo:
Txhawm rau ua qhov projectile, nws yog qhov yuav tsum tau yob ntawm cov xov tooj uas yuav tsum tau, nyeg, raj yuav tsum nkag mus rau ntawm rab phom. Plug cov tog raj ntawm ib sab nrog plaster, ua ntej threading lub wick. Txhawm rau txhaws qhov projectile, koj tuaj yeem nqa cov hnub qub, sib xyaw ua ke nrog pob tawg thiab tawg rau hauv lub projectile. Tom ntej no, tsav ib lub wad nyob saum cov hnub qub, thiab nchuav gypsum rau saum nws. Tom qab ntawd cia lub plaster kom qhuav. Ntawm qhov qis ntawm qhov projectile, koj tuaj yeem siv cov roj nplua nyeem los ntawm cov lus muaj rau koj.

Qhov thib peb theem yog lub ntsiab ib, qhov tshwm sim nyob ntawm nws. Nov yog qhov muab cov khoom rho tawm. Nws yog tsim nyog sau cia tias cov nqi rho tawm yuav tsum muaj tshwj xeeb ntawm cov hmoov txhuas. Cov txheej txheem tsim tawm muaj raws li hauv qab no:
Ntxig cov wick rau hauv cov cug, tso rau hauv cov phom siab, tso cov wad thiab qis dua nws nrog kev pab ntawm wad mus rau nres, ntxig rau qhov projectile, rauj wad nrog lub hauv paus channel zoo, ntxig rau projectile thiab tsav ob lossis peb cov lag luam tsis hnov lus. Rov ua qhov txheej txheem no. Los ntawm txoj kev, tsis txhob rauj lub tshuaj khib tag, tawm kaum mus rau kaum tsib centimeters - rau kev txhaj tshuaj siab. Ua rau kev txhaws rau hauv txoj hauv kev uas lub pob taws tsis raug puas ntsoog, coj tus nqi tawm hauv qhov nyiaj ntawm 1/3 ntawm tag nrho qhov hnyav ntawm lub txim.
